Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

Syscoin Platform’s Great Reddit Scaling Bake-off Proposal

https://preview.redd.it/rqt2dldyg8e51.jpg?width=1044&format=pjpg&auto=webp&s=777ae9d4fbbb54c3540682b72700fc4ba3de0a44
We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.

Solutions

Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
  1. Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer.
  2. The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds.
  3. Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability.

Syscoin + Matic Integration

Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.

Proving Performance & Cost Savings

Our POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.
Addresses used: 100,014

It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.

Cost Savings

Total cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

Syscoin Bridge

Mainnet Demonstration of Syscoin Bridge with the Basic Attention Token ERC-20
A two-way blockchain interoperability system that uses Simple Payment Verification to enable:
  • Any Standard ERC-20 token to be moved from Ethereum to the Syscoin blockchain as a Syscoin Platform Token (SPT), and back to Ethereum
  • Any SPT to be moved from Syscoin to the Ethereum blockchain as an ERC-20 token, and back to Syscoin

Benefits

  • Permissionless
  • No counterparties involved
  • No trading mechanisms involved
  • No third-party liquidity providers required
  • Cross-chain Fractional Supply - 2-way peg - Token supply maintained globally
  • ERC-20s gain vastly improved transactionality with the Syscoin Token Platform, along with the security of bitcoin-core-compliant PoW.
  • SPTs gain access to all the tooling, applications and capabilities of Ethereum for ERC-20, including smart contracts.

HOWTO: Setup an Agent
Developer & User Diligence

Trade-off

The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.

Cost

Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.

Z-DAG

Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).

Benefits

  • Unique fee-market that is more efficient for microtransaction redemption and settlement
  • Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks
  • Provides high throughput and secure fulfillment even if blocks are full
  • Probabilistic and interactive
  • 99.9999% security assurance within 10 seconds
  • Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain
  • Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus

Z-DAG White Paper
Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana

Trade-off

Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.

Syscoin Specs

Syscoin 3.0 White Paper
(4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging)
  • 16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average
  • SHA256 merge mined with Bitcoin
  • UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core
  • Z-DAG on asset layer, bridge to Ethereum on asset layer
  • On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution
  • Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers.
  • Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization.
  • Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this.

Wallets

Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask.
Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2.
Current supported wallets
Syscoin Spark Desktop
Syscoin-Qt

Explorers

Mainnet: https://sys1.bcfn.ca (Blockbook)
Testnet: https://explorer-testnet.blockchainfoundry.co

Thank you for close consideration of our proposal. We look forward to feedback, and to working with the Reddit community to implement an ideal solution using Syscoin Platform!

Why Ethereum Problems Make UMI the Flagship Among the New Generation Cryptocurrencies

Why Ethereum Problems Make UMI the Flagship Among the New Generation Cryptocurrencies

https://preview.redd.it/8skuypxp9lj51.jpg?width=1023&format=pjpg&auto=webp&s=ba5a38ba592428f92dc7c1943a780ff127132875
Ethereum cryptocurrency that comes second in terms of capitalization on the crypto market is traditionally seen as fast and profitable. However, over the last few weeks it's had a rough patch. Since early August, the network has had huge queues of transactions pending processing while fees have skyrocketed and surpassed the historical high.
The main issue though is that even fees of a few dollars per transfer don't help get rid of the“traffic jams”. The cause of this is numerous DeFi projects and a huge number of financial pyramids based on the Ethereum platform. Both generate excessive load on the network.
The situation is downright unpleasant, and our users might question whether the UMI network could face a similar challenge? We'd like to assure you it could not. The UMI network is by default protected against these problems — it cannot have “traffic jams”, fees or financial pyramids. But first things first.
How has the Ethereum network ground to a halt?
In its report dated August 4, Arcane Research that provides analysis within the field of cryptocurrency stated that over the previous week the daily size of transaction fees in the Ethereum network has surged up to a record high for over two and a half years. On August 3, the median value #%D0%9F%D1%80%D0%B8%D0%BC%D0%B5%D1%80_%D0%B8%D1%81%D0%BF%D0%BE%D0%BB%D1%8C%D0%B7%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F)of the fee amounted to $0.82, with the overall amount of transaction fees totaling $2 mln. However, it only signaled the start of real problems.
Over the next week, fees continued to grow and by August 11 the median fee value almost doubled equaling $1.57. Larry Cermak, an expert at a big analytical and news-making crypto portal The Block, wrote in his August 15 tweet that over a week the total amount of transaction fees in the Ethereum network totaled $34.5 mln, having surpassed its historical high. Meanwhile, in the Bitcoin network that is seen as too expensive the fees were almost four times lower at $9 mln.
The total fee amount paid by cryptocurrency users over a week:
  • Ethereum — $34.5 mln;
  • Bitcoin — $9 mln;
  • Monero — $2,240;
  • Tezos — $1,876;
  • Cardano — $1,615;
  • XRP — $1,138;
  • BSV — $1,102;
  • Stellar — $1,059;
  • Bitcoin Cash — $1,027;
  • UMI — $0. Let's talk about it a little later.

https://preview.redd.it/z9azd9v6alj51.png?width=1600&format=png&auto=webp&s=25c365d6e14665ecda4a2b8d19b2fc57dd5cde1e
Historical Growth Chart for Ethereum Fees. Source
The existing situation shows that Ethereum is actually not as fast and profitable as commonly cited. Additionally, this could happen to almost any cryptocurrency except UMI that charges no fees whatsoever. We will tell you why.
Why have these problems emerged?
There is nothing unoriginal: the Ethereum network simply can't handle an increased load. Arcane Research analysts consider that a principal cause of this situation is the constantly increasing number of the DeFi ecosystem projects built on the Ethereum blockchain. Their number is growing all the time which causes the overload of the network. As of August 12, the total amount of funds in DeFi applications reached $4.3 billion which is 19.5% higher than that in the past week. At the time of writing this article, the amount surged to $6.21 billion. You can see the current data here. What is the most unpleasant about DeFi protocols is that a lot of them are scam projects.
Which is not the worst part though. There is also another factor that significantly slows down the Ethereum network. There are a lot of pyramid-like projects that are built on the EOS platform and use smart contracts. One of them is SmartWay Forsage, which regularly overloads the network with a large number of transactions, causes traffic jams, and, consequently, leads to increased fees (keep in mind that Ethereum miners choose transactions with a higher commission). Vitalik Buterin, the co-founder of Ethereum, revealed his disapproval of the SmartWay Forsage methodology and asked them to "leave and not pollute Ethereum ecology in the future". However, the project is slow to do this — it continues to deceive users.
This is only the tip of the iceberg of scam projects which abounds on the EOS network –– they continually emerge, work for a while, then go down as scams and are replaced with new ones. This never-ending stream of "investment projects" based on the Ponzi scheme overloads the system. This is the reason why Adam Back, a pioneer of the crypto industry and founder of the technology company Blockstream, equated Ethereum with such infamous projects as Onecoin and Bitconnect. Adam Back's solid dig at Ethereum became the subject of much debate among crypto enthusiasts.
Of course, it all doesn't mean that Ethereum is a bad cryptocurrency. On the contrary, it has a lot of advantages over other coins. But all that has happened exposes Ethereum's faults which must be eliminated. The problem is that they may not be fixable. It is far from certain that the developers will be able to get rid of all the defects as the system has huge scalability problems.
The crypto community has to admit that Ethereum, like other first-generation cryptocurrencies, has issues with capacity, fees, and scalability and is gradually becoming obsolete.
2020 is the time for young innovative cryptocurrencies such as UMI.
UMI is the flagship of new-generation cryptocurrencies.
In real fact, any cryptocurrency could face it. Each cryptocurrency charges fees which typically surge when the network is overloaded or the price is going up. Everyone will remember 2017 when in line with price growth and the network's overload Bitcoin transaction fee reached a high of around $40.
But when it comes to UMI, it works the other way round. The UMI network's advantages are high capacity, no fees, and scaling possibilities. It uses the best and fastest crypto industry solutions and excludes all inefficient methods by default. Smart optimization in combination with the Proof-of-Authority technology operating on the master node basis enables almost instant payments.
At the stage of network testing, an incredibly high capacity was achieved:
  • up to 4,369 transactions per second;
  • up to 262,140 transactions per minute;
  • up to 15,728,400 transactions per hour;
  • up to 377,481,600 transactions per day.
Ethereum processes about 20 transactions per second. It means that the UMI network can process transactions that Ethereum processes over a year in 1 to 5 days — and with no fees.
https://preview.redd.it/rwohnov3alj51.png?width=1125&format=png&auto=webp&s=4329b75c0bd8b7a22276b529f5ca433d17a0874f
The UMI network can process transactions that Ethereum processes over a year in a few days and with no fees. More details
What is more important is that less than 0.001% of the network's overall potential is used now. The UMI network has a lot of reserve capacity and can handle hundreds of thousands of times heavier load. Moreover, with scaling possibilities, UMI can keep up with the times. The UMI code ensures the safe introduction of any upgrades — the network can be easily modified and scaled with cutting edge technology solutions. In other words, traffic jams will never pose a problem for us. UMI will instantly process all transactions, with no fees. Always.
https://preview.redd.it/t0068th0alj51.png?width=544&format=png&auto=webp&s=019f46ec8c093480c4638cf098312a5a146134a8
A real-time speedometer displays the number of transactions processed by the UMI network per second. Link
Additionally, unlike Ethereum and other cryptocurrencies, the UMI's staking smart contract prevents possibilities of any pyramid schemes, meaning eliminates their negative influence. Our staking is completely safe and secured against scammers. Read more about this in our article. Any UMI staking structure could work forever. In other words, you can multiply your coins at a rate of up to 40% per month for an indefinitely long period of time.
UMI doesn't inherit the disadvantages of the first-generation cryptocurrencies. This is an innovative, carefully designed network based on state-of-the-art technologies. UMI is an ambitious step toward the future. And we're making it together right now!
Sincerely yours, UMI team

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.
  • Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
  • Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with a blockchain network structure, a notion first created by Stuart Haber and W. Scott Stornetta in 1991.
  • Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
  • The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
  • With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.

https://preview.redd.it/s2gmpmeze3151.png?width=256&format=png&auto=webp&s=9759910dd3c4a15b83f55b827d1899fb2fdd3de1

1. What is Bitcoin (BTC)?

  • Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
  • Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
  • The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
  • The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
  • Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).

2. Bitcoin’s core features

For a more beginner’s introduction to Bitcoin, please visit Binance Academy’s guide to Bitcoin.

Unspent Transaction Output (UTXO) model

A UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.
https://preview.redd.it/t1j6anf8f3151.png?width=1601&format=png&auto=webp&s=33bd141d8f2136a6f32739c8cdc7aae2e04cbc47

Nakamoto consensus

In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).
The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.
Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs.
As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”).
Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.
With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.
Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.

The blockchain

Block production

The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979.
With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”).
An illustration of block production in the Bitcoin Protocol is demonstrated below.

https://preview.redd.it/m6texxicf3151.png?width=1591&format=png&auto=webp&s=f4253304912ed8370948b9c524e08fef28f1c78d

Block time and mining difficulty

Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty.
Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly.
Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.

What are orphan blocks?

In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.
It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.
Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.
The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.
However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.

3. Bitcoin’s additional features

Segregated Witness (SegWit)

Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017.
SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin.
SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become.
https://preview.redd.it/depya70mf3151.png?width=1601&format=png&auto=webp&s=a6499aa2131fbf347f8ffd812930b2f7d66be48e
The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit.
Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade.
Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values.
For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890.
Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid.
This can create many issues, as illustrated in the below example:
  1. Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
  2. Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
  3. At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
  4. Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
  5. As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID.
Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.

Lightning Network

Lightning Network is a second-layer micropayment solution for scalability.
Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins.
Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ.
A list of curated resources relevant to Lightning Network can be found here.
In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions.
Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel.
https://preview.redd.it/cy56icarf3151.png?width=1601&format=png&auto=webp&s=b239a63c6a87ec6cc1b18ce2cbd0355f8831c3a8
One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel.
However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.

Schnorr Signature upgrade proposal

Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain.
https://preview.redd.it/hjeqe4l7g3151.png?width=1601&format=png&auto=webp&s=8014fb08fe62ac4d91645499bc0c7e1c04c5d7c4
However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys.
This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block.
https://preview.redd.it/axg3wayag3151.png?width=1601&format=png&auto=webp&s=93d958fa6b0e623caa82ca71fe457b4daa88c71e
The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually.
Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.

4. Economics and supply distribution

The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years.
As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.

Zhuling Chen
It’s always great to hang out in this group. This group means a lot to the Aelf community. It is the first Aelf community and has been there through all the ups and downs in the world. I would like to start with wishing everyone is staying safe at home during the virus outbreak. It definitely has been a difficult time for all of us, but together we can pull through it.
We understand that the situation is quite striking to all of us. But I really believe that the solution to the virus outbreak is about more global coordination and collaboration.
All of you to be assured, our team in different places are all safe and working from home as normal.
The Aelf team in Beijing were among the early ones experiencing the virus outbreak. As everyone was on the way home for Lunar New Year holiday and then experienced a total city lock-down followed by a 40 days’ work from home policy. It was definitely not easy for them, but our team stayed strong, took necessary precautions and focused on work with the right morale. Mappo has recently published some tips on how to work from home effectively based on our experience. Do check it out. Despite not working in the office since February, we have achieved great progress, including launching Aelf 1.0 preview, which is an important milestone in technical delivery and also the roadmap to mainnet launch (which listed out the essential steps for the community to work together to launch a successful public network)
Let's first talk about Aelf v1.0 preview. It is the cornerstone of the mainnet launch. The product itself has all the features that the public network is needed. The codebase has been reviewed and tested rigorously by the team. And a few highlights of how the network would look like:
  1. The code allows a stable and high throughput blockchain network to operate publicly.
  2. For developers, they will love how flexible the system is to be customized, the number of tools and documentation to help them start developing applications on the network
  3. For the whole community, the system is an ever-evolving one where the voting system is ready in place to conduct network-wide voting on various topics, such as transaction fee adjustment, network protocol upgrade, incentive adjustment, etc
  4. Aelf system is able to run multi-chain architecture where each side chain will host different applications and still ready to work with each other
So you may ask since the software is ready, why have we not yet launched the public network? The answer, in short, is that a public blockchain is launched not by a team but through a community effort and that's why we are coordinating the community effort based on the roadmap we proposed. Aelf team has launched the public testnet based on Aelf v1.0 preview and currently, all nodes are under the team. The goal is to let the community and elected nodes to take it over and launch it on a global scale. Not only launch it but also be familiar with the network and also set the launch parameters in a decentralized way. If we take a car as an example, we have made the car, but ultimately the drivers are you guys and therefore before it really hits on the road, we need to guide the community to do a test drive, adjust the car based on what really works for YOU, and ultimately let YOU drive the car freely and safely
So how are we going to help the community launch the network:
First of all, we have launched the codes, documents about the economic system and governance model and technical features. With all the things available, you are able to understand what the system is about, as a token holder what's your benefit in the system, and being a node in the system plays a big role in the governance
Next, without yet electing the nodes, we will get all token holders to join the current Aelf network through a mapping event. That means as long as you have Aelf tokens, you will be able to get 1:1 test tokens on the public testnet. that gives you full access to all the features, and you will feel like you are already using the mainnet. You will get rewarded in making transactions, voting, etc.
Do try out the Aelf wallet and voting features, you will see how easy to transfer tokens cross-chain. and also how flexible the system allows people to make changes. For example, the community may want to adjust the block rewarding parameters or fees to use certain services on mainnet, they can initiate a discussion and then vote in the system and once voted through, it will be reflected on mainnet.
For people or organizations that want to play a bigger role in the system, we will do a dry run of node election. Take it as the real node election before mainnet launch. We will see who the active members of the community are and being trusted by the community. Among the nodes, we will form a network launch committee. The committee will be the crucial party to oversees and ensures the smooth launch of Aelf mainnet, instead of just relying on the Aelf team. This is our step towards decentralization.
The committee will agree on the actual launch process, final checking all the parameters in the system to be ready for launch and then decide when the criteria are met to launch the network. Once all that is decided. We will invite all interested nodes to apply for the election and let the community know what's their plan to grow the Aelf network. the network will initially be launched with a few nodes from the committee and gradually be replaced by the selected nodes (a bootstrap phase). Along the way, we will work with exchanges to conduct token swap (which we are also designing an innovative system to further enhance security and usability of Aelf tokens in exchanges)
Among this isolated and worrisome time, at least we all have something to look forward to: a successful launch of Aelf network! Once it is launched, we are excited to see a vibrant and technically superior network that is good for Dapps to run on top of it.

Doris Guo Q1: As a Blockchain start-up, what difficulties have you overcome when starting Aelf project? What motivates you to solve difficulties and achieve success today?
Zhuling Chen First, just like launching any start-up, its community and investors are usually regional. There is always some bias on if Asian projects are solid. It is really rare to have an Asian project to be supported by western funds and community from day 1. We were lucky to have overcome that obstacle. Having a global investor line-up from day 1. Having a global team from day 1 and also working with a global community from day 1. This benefited us to have an international perspective which is crucial in the blockchain industry.
Secondly, as a hardcore technology company, it is really hard to put in plain words what is our ambition. Our ambition is huge, achieving key innovations in multiple fronts of blockchain technology and organically combined them to serve real users for the future. Our marketing team has been working really hard to elaborate on what Aelf is. Now we have come to a point that the product is ready. Therefore, it is much easier for all of us to understand how solid Aelf is by trying out the network ourselves! That's exactly what the following events will be about - Try out all the exciting features of Aelf network before mainnet launch.
Doris Guo Q2: What critical problems do you see occurring in the blockchain industry nowadays? How does Aelf solve these problems?
Haobo Ma First, we need to distinguish the difference between BTC and ETH. One is Digital Cash and the other is the Smart Contract Platform. Aelf addresses most of the latter's problems. In short, it can be summarized as performance, end-user friendly, developer-friendly, network economy, and self-governance and upgrading. Each of these areas will probably take up a lot of space, and as a whole are the issues described in our two white papers. In short, Aelf is faster, end-users do not need to know the rules of the blockchain, developers can set up the development environment in 10 minutes, have a good economic model and can carry out proposal governance on the chain.
Doris Guo Q3: What is your long-term vision about the industry which Aelf is working at? Are you afraid someday there will be another project with more innovative technology can replace Aelf?
Haobo Ma Let's talk about where Aelf stands in the traditional Internet. It is essentially a cloud service provider, Aelf provides resources and infrastructure for developers to deploy their services, known as smart contracts. We eventually want Aelf to grow like AAA (Amazon, Azure, AliCloud). Because Aelf is a network that can be dynamically scaled, we can accept any new technology, some of the more advanced technologies we can put on a side chain.
Doris Guo Q4: Why did Aelf choose for cross-chain interaction?
Haobo Ma As I mentioned earlier, Aelf solves the Smart Contract Platform problem. However, there are other digital cash problems as well which we would need to use existing infrastructure such as Bitcoin's chain in order to interact with Bitcoin. There are a lot of infrastructures on Ethereum that we want to interact with. Multi-chain on Aelf network mainly is to isolate resources to improve network performance and network stability.
Doris Guo Q5: What difficulties do the Aelf team have now (I talk about COVID-19)? How does the Aelf team solve it? Have you changed the roadmap?
Haobo Ma There is no great impact. The teams in Singapore and Beijing are communicating with each other remotely on a regular basis. The only change is that most of us are now working from home which has no impact and in fact, it seems conducive to the acceptance of more community developers in the future to come. From the internal working schedule and development timeline, there is no great impact. We do not publish specific timeline as we do not want short term holders (traders) to create too much negative pressure on product development.
Doris Guo Q6: Aelf is an open-source blockchain, and there's the common problem of taking a substantial amount of time for the different participants to agree on strategic decisions. What types of governance models do you use in Aelf to address this issue???
Haobo Ma The issue is about public blockchain network, and who can decide the direction of the network. Our answer is long-term holders. For the short-term holders (traders), we refuse to allow them to participate in any discussion of the direction of Aelf because the short-term holders are likely to make a profit and sell quickly, which is essentially the same example of a person who cheats the President and then runs away for his personal gain. We defined a number of proposal processes, including the logic of the two-party system in the United States, and the participation in the referendum to ensure that the final proposal represents the majority. At the same time, we are looking for some legal solutions to avoid bifurcation, such as prohibiting exchanges from intervening in bifurcated new tokens. While we cannot limit a community, we should be able to find ways to limit a centralized organization. This restriction is akin to a ban on national secession.
Doris Guo Q7: How will Aelf empower Investors, Companies, Developers, Platform Users to deliver impactful solutions and bring value to people all over the world?
Haobo Ma We will learn from the operational experience of successful foundations such as the LINUX foundation and license some commercial companies to use Aelf solutions to solve business problems. At the same time, Aelf is an open-source product under the MIT License, and we accept any use that does not violate this open-source principle.
Zhuling Chen Let me add on to Haobo’s statement: to incentivize and empower the community, we are also exploring ways to let the community decide how to use the funds for Aelf (allocate to where it matters to our community) once mainnet is launched. This means you guys can decide what are the projects to be funded on Aelf, etc
Doris Guo Q8:When will the node campaign start? How will Aelf attract users to participate in nodes election?
Haobo Ma According to our published roadmap, the timeline can be dynamic, but I don't think it will be too long. The main idea is to let everyone understand what we envision Aelf to be like, and what are the rights and benefits of being a node in the future. We hope to find nodes that fully recognize the efforts of Aelf at the present stage and are willing to participate in the future development of Aelf. We will run a simulation of the node campaign on the testnet and set up a temporary mainnet launch committee. Please follow our official Twitter for more upcoming details!
Doris Guo Q9: Token swap form 2 is some kind of cross-chain transfer? It will be handled by a smart contract?
Haobo Ma It is handled by the smart contract, we define an asset cross-chain transfer protocol, but it may be opened after a snapshot.
Doris Guo Q10: Which Exchanges will support token swap? Do you have any plan to list Aelf in some big exchange like Binance, Houbi, Kucoin, .......?
Haobo Ma We are already in talks with some exchanges, there is still competition between exchanges, and many are still hoping to attract more users by getting access to mainnet token swap early.
Doris Guo Q11: Aside conversion of the current tokens to mainnet tokens, what other main features will be accomplished with the mainnet launch?
Haobo Ma We have a documentation file that has been published, which has listed some features: https://Aelf.io/gridcn/Aelf_public_testnet_and_supporting_features_introduction_en_v1.0.pdf
Doris Guo Q12: Do you have any plan to burn or buyback your coin?
Haobo Ma We have plans for the community to govern through DAO, we have no interest in short-term price incentive adjustment as we would prefer to drive the project to higher adoption. After mainnet starts operation, there will be a part of network revenue get destroyed automatically.
Doris Guo Q13: Often, as a newbie developer, I face difficulties on most blockchains. How easy and convenient is it for me on Aelf, and what programming language and tools are needed??
Haobo Ma We set up staging for DAPP developers on GitHub and configured CI. Develop a smart contract using C# with React Native on the front end. So, in fact, developers can fork the source code without setting up the environment locally, and you can conduct unit testing with the help of CI. You can also release the smart contract and generate the installation package of iOS and android online. https://github.com/AElfProject/Aelf-boilerplate
Doris Guo Q14: What is the progress of business development and what are some of your commercial partnerships? How will Aelf rapidly develop the number & performance of DAPP?
Haobo Ma First of all, the blockchain industry is still fairly small and users with ETH and EOS wallets are considered a very small group and its not effective to even promote within these groups. What we need to consider is how to enable users who have never been exposed to blockchain to use DAPP. The competitiveness of Aelf is to make it easier for Aelf developers to promote their DAPP to ordinary users, rather than to teach ordinary users a lot on blockchain knowledge. The average user doesn't like to hear about private keys, mnemonic, Gas Price, RAM, CPU, etc. Only until we solve such problems, companies that need to solve problems through blockchain will be more inclined to use Aelf in technology selection. Therefore, our main work is to explain the competitive advantages of Aelf, ETH and EOS to everyone. We have some business cooperation’s, but we also believe that simply through case-by-case business cooperation will not be able to gain adoption so quickly, therefore we still need to put our products to stay ahead of the next generation.
Doris Guo Q15: What other activities can encourage more people to be confident about Aelf?
Haobo Ma We are only going to state the truth by having those that have faith in us to stay and those that don't to leave. The development of Aelf is not driven by a single foundation, but by a steady stream of contributions from the community. In the future, we will also place the activities in the DAO for on-chain governance, and let the community make decisions by itself.

Kun Aguero As you know that in the present market situation many new coins or either dying or thriving for liquidity? How will you manage this liquidity problem?
Zhuling Chen Aelf started in 2017. we have gone through a few cycles in the market, still, remember the big down period in 2018-2019. Aelf is financially solid and the team has always been working hard. if you are referring to liquidity in exchanges, we are among the lucky ones that are listed in all major exchanges
Xinshu Dong Hello, great discussions! I would like to ask what are the criteria to join the committee for launching the mainnet? Would love to participate
Zhuling Chen Hi xinshu, great to see you here. The committee will be chosen among the nodes elected during the testnet dry run. Which means, it is really important to participate in the testnet dry run and also start to establish your reputation in the community so that people will elect you as a node. The detailed criteria will include what is your plan to help Aelf to grow, tech competency and reputation.
An Da What are Aelf’s achievements in 2019? Who had supported you to get those things?
Zhuling Chen To name a few, in 2019, Aelf is one of the most active projects on GitHub. This means Aelf is evolving and improving fast in this space and our team has the tech strength. In addition, we have also successfully listed on all major cloud service providers, such as AWS, Azure, Google. So large companies can easily launch Aelf side chains in their organization with minimum hassle.
John How does the voting for master nodes candidates occur? And why is the development of this system important for your project?
Zhuling Chen Voting is going to be pretty simple. All token holders can vote for the nodes they support on our block explorer.
Miha After mainnet lunch, how will you assure that transactional fees will stay low? We know what sometimes happens to fees on ETH blockchain.
Zhuling Chen First of all, due to the fact that is Aelf is scalability, this will reduce transaction fee. Secondly, all transaction fees will be voted by the nodes (which will be elected by you). So they will represent your interest
Bobbyfernandito Currently, as we see All projects are concerned with the speed and security. So, tell us here - what are the facilities Aelf provide to their user and investors?
Haobo Ma Security: we have an automated smart contract code audit. During contract deployment, production nodes and the community audit participation are required. On the other hand, we are also planning to provide a standardized model of centralized exchange access for 100% asset certification and emergency measures to deal with exchange attacks, which we will be released later. Speed: Aelf has been working on improving performance, which is transparent to users which they can also experience by themselves.
An Da What effect does Aelf token have on the Aelf ecosystem? Holding Aelf, what benefits will users receive?
Zhuling Chen Holding ELF enables you to use all the services on the Aelf network. ELF has a deflating system where the total amount will reduce as the network grows. token holders can also vote for the nodes to run the network and also vote for big decisions in the network. part of the fees in the system will also be distributed to token holders via a smart contract
ahihi132 Which companies do you view them as potential partners and that they are somewhat also beneficial for both the user base and Aelf itself?
Zhuling Chen Great question, if I could write a wish list, that will be: let medium-sized financial institutions to use Aelf to challenge the big boys. Let telecommunication companies use Aelf for micro-payment and other innovative business models. We also would like to try out a few public sector projects, which blockchain will is still more transparency and trust
Misun Q1: Which programming languages are you using in your project? And why? Q2-What are another big MILESTONES you have planned for 2020 roadmap and how are they supposed to benefit your costumers? Will it be an exciting year?
Haobo Ma For Q1: We mainly use C# for development, I personally like it. Performance is good, development environment IDEs are strong, and C# creators are influential in the industry. We believe in the right thing, though it may take a while to develop. The smart contract will then add support for multiple languages, such as WebAssembly, depending on the needs of the community. Now it seems that C# is enough.
Hambi crypto Which platforms are your competitors? How will you soar above them, and what better things do you offer than them? So, What’s your outlook on the future of cryptocurrencies in this year and next few years?
Haobo Ma As I have already mentioned this before, Eth and Eos. We provide better performance, cross-chain support (already implemented), end-users do not need to know the details of the blockchain, developer’s payment models and so on.
Floris-Jan What plans is Aelf making to prevent centralized exchange to take over the DPoS algorithm like what happened to Steem? Are we talking about blacklisting exchange wallets, or having the foundation say "No", or putting all trust in the community?
Zhuling Chen Great question, Floris. I’m not going to give away all the details of what Haobo has proposed to work on this, but in a nutshell, in Aelf system, exchange wallets will not be allowed to vote, but only the sub-wallets for each individual can vote. This will also help exchanges to prevent hacking and theft in the future
Alex What your plans in place for global expansion, are Aelf wallet focusing on the only market at this time? Or focus on building and developing or getting customers and users, or partnerships? Can you explain this?
Haobo Ma Our core focus will be through the developers to promote, developers will help Aelf to attract more users. So our product has to be attractive to developers. Just like AWS, they only focus on getting their service right, their developers will think about how to promote it. We don't want to burden them in their promotion process.
Ellkay What do you think are the major threats and barriers that could face the development and adoption of Aelf?
Haobo Ma If I'm a DAPP developer and I need to promote my APP to people who don't recognize blockchain, then I'd like to choose a platform that doesn't have to explain a lot of blockchain details to the end-user, so they can use it easily. We've provided some options in the Boilerplate that allow you to log-in simply via QR code + Password, and our recommended Dapp is an independent wallet and a separate iOS/Android application.
ahihi132 Give me some important reasons why we need to hold Aelf token where in fact hundreds of projects failed and it went to bankruptcy or even developers run when they collect millions/billions of funds?
Haobo Ma First of all, we will not give any suggestions as we only describe the fact that the long-term token holder will be able to govern the Aelf network, get Aelf mining reward and Aelf network profit. At the same time, Aelf network is a deflation model, Aelf network received transaction fees, profit dividends will immediately destroy 10% etc. All investments are risky, and we don't judge the behaviour of other developers. There are so many things in this world that cannot be understood and unfair. It is important to do our job well. I cannot explain these things.
见愁 I remember that boss Ma mentioned to only find those truly innovative applications and enterprises with blockchain, how to find and win partners in these aspects?
Haobo Ma When Linus was developing Linux, I did not think he would find a lot of collaboration when the code was not good. The response we can give is that we already have a lot of interest in cooperation, including what we have announced, what we have not announced, etc.
见愁 How interested are cloud computing providers in participating nodes?
Haobo Ma The vast majority of our nodes should be using cloud services, and as long as a large number of our 17 nodes and other candidate nodes are based on cloud services, our network robustness is determined by these cloud computing providers. Of course, in the expansion, we can also use cloud computing services.

Weekly Update: Parachute Townhall, Welcome $GET to ParJar, Uptrennd reaches 50k members, Fantom on IncognitoChain... – 6 Dec - 12 Dec'19
Hi Parachuters! As part of 2 of 3 from today's rapid catch up series of pending updates, here’s your week at Parachute + partners (6 Dec - 12 Dec'19):

As mentioned last week, Cap and Ice hosted a townhall to talk about where we are at and where we are heading along with ample feedback and Q&A from the community. We covered a lot of ground: "value hypothesis for ParJar, Product Market fit, and our growth approach for 2020...performance of two key PAR utility metrics, staking and gas, and how we see growth for each in 2020...questions from the community and reviewed upcoming community initiatives". Click here to catch up on all that happened. GET Protocol’s $GET token was added to ParJar this week. Belated Birthday wishes to Doc Vic from Cuba. Jason lost a 5k $PAR wager with Cap on Victor’s age. Haha. Congratulations to Martha for winning this week’s Parena. As per the latest Fantasy Premier League (#FPL) update shared by LordHades this week, he is still ruling the charts at the top with NovelCloud and Alexis hot on his heels. From next week, "You can now view your first opponent in the 2019/20 FPL Cup on the My Team page - under Leagues". While you slay those miles with the Parachute Running Club (which has done 44 miles so far BTW), here’s a podcast to listen to. Cap’s recommendation: "It's geared towards people building products - but super super useful to think about any products you use. Skip to like 9 minutes in to skip through all the advertiesments ". Yes, I know. Cap wouldn’t be Cap without typos. Typos FTW!
Parachute townhall
Parachute-themed shirts designed by Doc Vic and Alejandro on Doc’s birthday. These are sick!
If you want to see yourself on the Parachute world map, make sure to enter your location here. The entries are anonymous. In this week's Parachute Fantasy Football League update, Hang is in the first position followed by Clinton and Andy. Connor made it to the playoffs and is now in 4th position. So it means farewell to Nilz, Ken, Kamo and Cap from this season. CoD mobile players, don't forget to join the Parachute WarZone hosted by Doc Vic from Cuba. I hear there's $PAR and $AMGO to be won! The TTR Hat Contest ended this week with some solid entries running in the lead. Epic creation Wendell! In this week’s creative prompt by Jason, Parachuters had to “do 3 nice things for a total stranger”. Basically, be a true blue Parachuter 😊. For this week's Two-for-Tuesday, Gian made it free-for-all. No theme. Post music as you wish and win 500 $PAR. Cool! Benjamin and Charlotte hosted trivias in TTR this week. Those were loads of fun! Andy announced the start of a College Football Bowl Game Pickem contest in Parachute. 100k $PAR prize pool. Doc Vic hosted another round of Champions League wager this week in TTR.
So much epicness in one picture. Jose, you are a genius!
Andy's Advent Calendar journey continues
Catch up on the latest aXpire update and 20k AXPR burn here and here respectively. As you would already know, instead of pitting both startups against each other, XIO decided to accept both Opacity and Uptrennd into the incubator program and opened up staking for them. This marks the official launch of the XIO Blockchain Incubator and it’s been a roaring start with USD 7k worth of tokens locked up in one hour and Opacity portal getting oversubscribed in no time. Video instructions for staking can be found here. Read up on the startups here. In three days, the total staking crossed 1M XIO levels. Insane! That is a great metric to measure performance. How does the $XIO token play a role in all this? The crew explained in this tweet thread. And with that a series of related discussions got off starting with the possibility of self-nomination for startups. Have a sub-100 CMC project that you think should be part of the incubator? Don’t forget to tag them. Plus, a cool 25k $XIO giveaway was launched. Remember, meaningful conversation is always welcome at the incubator and more often than not, they get rewarded. Check out the latest update on the Birdchain App SMS feature along with an expanded list of supported countries. Silent Notary reduced the $LAW token requirement for running a Masternode from 100M to 20M this week. Russian research company sudexpa.ru also gave its vote of confidence to Silent Notary in terms of its immutability. Wibson Marketing Manager Fi Scantamburlo attended the Latin American Bitcoin Conference Uruguay to speak on Data privacy, monetisation and how Wibson helps achieve these. Opacity now allows shared file preview for uploaded docs.
Shared File Preview on Opacity
Fantom's foray into the Afghan Ministry of Health's efforts to fight counterfeit drugs and other public health initiatives were covered by Forbes this week. Last week, we shared that Sikoba's e-voting platform, Itugen, which is based on Fantom’s Lachesis consensus was released. This week, they published its technical whitepaper. With so many moving parts in the project and so much happening all around, a recap is always a welcome refresher to catch up. $FTM got listed on South Korea’s Coinone with a $KRW pairing. It was also integrated with the IncognitoChain project’s pDEX with a $pUSDT pairing (remember, Harmony was added to the same platform a few days back?). IncognitoChain allows cryptos to be transacted privately using sidechains including those coins/tokens which are not privacy-oriented. Fantom also launched a developer portal and technical documentation ahead of the XAR Network mainnet release. The interoperability bridge is out as well. This allows both ERC20 and BEP2 token holders to move their tokens to the XAR Network. The wallet allows both staking and delegation. For the guide to joining XAR Network as a validator node, click here. A simple guide to staking on XAR Network can be found here. The team also sat down for an AMA with COTI this week. Blockchain Magazine’s interview of Michael was published. Continuing with Uptrennd’s 24 Days of Celebrations started last week, this week they hosted an Escape Room contest and Photo contest. The latest $1UP tokenomics update can be seen here. After 11 months, the platform now has 50k users across 177 countries. Wowza! And wicked stats on the engagement metrics as well. Jeff’s interview with Crypto Beadles came out this week.
A few entries for the Uptrennd Photo Contest
Click here and here for the latest District Weekly and Dev Update from District0x. In case you missed this week’s Dapp Digest, you can watch it here. Aragon fans will be in for a treat since it features Aragon Co-Founder Luis Cuende as a special guest. Remember, we had discussed last week that the Shuffle Monster Raffle had crossed a 10k $SHUF pool. Turns out it got to 13k+. Wow! The latest Hydro developer update is a comprehensive roundup from the entire ecosystem. VCC Exchange listed $HYDRO with a $BTC pairing. Hydro’s security tokenisation protocol, Hail, moved to mainnet this week. The team travelled to Boston for MassChallenge Fintech. Hydro will be hosting a Banking-as-a-Service happy hour next week to talk on how they are building solutions in the BaaS space. For starters, don’t forget to read their article on blockchain applications in finance. The team appeared for an AMA with Apache Traders which also featured a 45k $HYDRO giveaway. Digital payments platform VoPay is now partnered with Hydro for end-to-end payment solutions using Hydrogen API and other Hydro tools. Hydro’s smart contract was audited by Callisto and passed their test with flying colours except for one "low severity" issue. The result: "The contract can be deployed". CTO Tim Allard was interviewed by Ethereum Network Nigeria as part of their Ethereum personality chat series. For the latest update on the community explorer Frost, click here. In Pynk’s first guest blog post, community member (or, Pynkster) Alistaire Wallace talks about what the coming year could hold for Pynk and its community of predictors.

This week at OST was all about the Pepo app: from angel investor Kartik to Rocket NFT’s Alex Masmej joining the platform, accelerator The Fledge using Pepo Conversations to power community-sourced improvements to businesses, Home for the Holidays Challenge to explain crypto/blockchain to relatives (with a total USD 2k in Pepo coins in prizes) and a “best lifehack” bounty posted by Jason on the app. If you’ve missed all SelfKey news from the past month, you can catch up from the November progress report. Also, did you know that the group Legion of Doom which was once considered to be the most capable hacking group in the world was in a long drawn feud with Masters of Deception in what is now known as the Great Hacker War? Learn more info like this from SelfKey’s latest article on hacking groups. Constellation CEO Ben Jorgensen will be speaking at the Crypto 2020 Summit. If you’re attending, make sure to say Hi. Arena Match announced a trading competition on DDEX with 4M $AMGO tokens to be won. Lucky Bluff Poker will be sponsoring next week’s Arena Match Raffle. The latest Harmony update compilation from the whole team can be found here. In the latest Pangea statistics (Harmony’s experimental staking game to test the limits of its tech), the average staking position is 1.8M $ONE with 75% of participants operate nodes themselves while the rest use delegates. Plus, check out the newest upgrades here. Honest Mining announced mainnet support for the native $ONE token swap. $ONE is also in consideration for listing on Binance US. The token was listed on Pionex this week. The Intellishare website registration and login functions will be down next week for a scheduled upgrade. Also, $INE traders make sure to keep a note of WBFex temporarily disabling the $ETH trading pair. Jobchain’s $JOB token got listed on Bilaxy exchange, P2PB2B exchange, SWFT Blockchain wallet and SWOP.SPACE exchange. The project was also given an A+ score by Xangle. Congrats!

And with that, it’s a wrap. See you again soon with another weekly update. Bye!

US Tax Guide for ETH and other cryptocurrencies

Introduction:  
Greetings, fellow ethtraders! Happy New Year! In the next few months, taxpayers across the US will be filing their 2017 tax returns. As an Enrolled Agent and a ETH/cryptocurrency investor and enthusiast, I wanted to write up a brief guide on how your investments in ETH and other cryptocurrencies are taxed in the US.
 
 
1. Are ETH/cryptocurrency realized gains taxable?
Yes. The IRS treats virtual currency (such as cryptocurrency) as property. That means if you sell ETH, BTC, or any other cryptocurrency that has appreciated in value, you have realized a capital gain and must pay taxes on this income. If you held the position for one year or less, it is a short-term capital gain which is taxed at your ordinary income tax rate. If you held the position for more than one year, it is a long-term capital gain which is taxed at your long-term capital gains tax rate. In most cases, this is 15%, but could also be 0% or 20% depending on your specific ordinary income tax bracket.
 
2. If I sell my ETH for USD on Coinbase but do not transfer the USD from Coinbase to my bank account, am I still taxed?
Yes. The only thing that matters is that you sold the ETH, which creates a taxable transaction. Whether you transfer the USD to your bank account or not does not matter.
 
3. If I use my ETH to buy OMG or another cryptocurrency, is this a taxable transaction?
Most likely yes. See #4 below for a more detailed explanation. If assuming crypto to crypto trades are not able to be like-kind exchanged, then continue on to the next paragraph here.
This is actually two different transactions. The first transaction is selling your ETH for USD. The second transaction is buying the OMG with your USD. You must manually calculate these amounts. For example, I buy 1 ETH for $600 on Coinbase. Later on, the price of 1 ETH rises to $700. I transfer that 1 ETH to Bittrex and use it to buy 37 OMG. I have to report a capital gain of $100 because of this transaction. My total cost basis for the 37 OMG I purchased is $700.
 
4. If I use my ETH to buy OMG or other cryptocurrency, could that be considered a tax-free like-kind exchange?
Probably not. The new tax law says that like-kind exchanges only pertain to real estate transactions. This was done with Section 13303, which replaced “property” with “real property” for all of Section 1031 (page 72 near the bottom). My personal interpretation:
In 2018 and going forward, cryptocurrencies can definitely not be like-kind exchanged.
In 2017 and before, it is a very gray area. I personally am not taking the position that they can be like-kind exchanged, because if the IRS went after a taxpayer who did this, the IRS would probably win and the taxpayer would owe taxes, interest, and probably penalties on every single little gain made from trading one cryptocurrency for another.
Here is a great interpretation of why trading cryptocurrency for cryptocurrency is probably not a like-kind transaction.
In my opinion, the biggest factor is that like-kind exchanges must be reported on Form 8824 and not just ignored. Therefore, if a taxpayer is claiming like-kind exchanges on crypto to crypto exchanges, he or she would have to fill out a Form 8824 for each individual transaction of crypto to crypto, which would be absolutely cumbersome if there are hundreds or thousands of such trades.
Here is another article about like-kind exchanges.
Here is the American Institute of CPAs' letter to the IRS, dated June 10, 2016, asking them to release guidance on whether crypto to crypto can be like-kind exchanged or not. The IRS has not responded to the letter.
 
5. How do I calculate the realized capital gain or loss on the sale of my cryptocurrency?
The realized gain or loss is your total proceeds from the sale minus what you purchased those positions for (your cost basis). For example, you bought 1 ETH for $300 in June of 2017. In December of 2017, you sold that 1 ETH for $800. Your realized gain would be $800 - $300 = $500. Since you held it for one year or less, the $500 would be a short-term capital gain taxed at your ordinary income tax rate.
 
6. Which ETH's cost basis do I use if I have multiple purchases?
The cost basis reporting method is up to you. For example, I buy my first ETH at $300, a second ETH at $530, and a third ETH at $400. Later on, I sell one ETH for $800. I can use:
FIFO (first in first out) - cost basis would the first ETH, $300, which would result in a gain of $500.
LIFO (last in first out) - cost basis would be the third ETH, $400, which would result in a gain of $400.
Average cost - cost basis would be the average of the three ETH, $410, which would result in a gain of $390.
Specific identification - I can just choose which coin's cost basis to use. For example, I can choose the second ETH's cost basis, $530, which would result in the lowest capital gains possible of $270.
 
7. If I end up with a net capital loss, can I claim this on my tax return?
Capital gains and capital losses are netted on your tax return. If the net result of this is a capital loss, you may offset it against ordinary income on your tax return, but only at a maximum of $3,000 per year. The remaining losses are carried forward until you use them up.
 
8. What is the tax rate on my capital gains?
If long-term, the tax rate is 0%, 15%, or 20%, depending on your ordinary income tax bracket. If short-term, the tax bracket you’ll be in will depend on your total income and deductions. The ordinary income tax brackets are 10%, 15%, 25%, 28%, 33%, 35%, and 39.6% in 2017 and 10%, 12%, 22%, 24%, 32%, 35%, and 37% in 2018 and going forward.
Here are the 2017 and 2018 ordinary income tax brackets.
Here are the 2017 and 2018 long-term capital gains tax brackets.
Here is a detailed article on how the calculation of long-term capital gains tax work and how you can take advantage of the 0% long-term capital gains rate, if applicable.
 
9. If I mine ETH or any other cryptocurrency, is this taxable?
Yes. IRS Notice 2014-21 states that mining cryptocurrency is taxable. For example, if you mined $7,000 worth of ETH in 2017, you must report $7,000 of income on your 2017 tax return. For many taxpayers, this will be reported on your Schedule C, and you will most likely owe self-employment taxes on this income as well. The $7,000 becomes the cost basis in your ETH position.
 
10. How do I calculate income for the cryptocurrency I mined?
This is the approach I would take. Say I mined 1 ETH on December 31, 2017. I would look up the daily historical prices for ETH and average the high and low prices for ETH on December 31, 2017, which is ($760.35 + $710.12) / 2 = $735.24. I would report $735.24 of income on my tax return. This would also be the cost basis of the 1 ETH I mined.
 
11. Can I deduct mining expenses on my tax return?
If you are reporting the income from mining on Schedule C, then you can deduct expenses on Schedule C as well. You can deduct the portion of your electricity costs allocated to mining, and then you depreciate the cost of your mining rig over time (probably over five years). Section 179 also allows for the full deduction of the cost of certain equipment in year 1, so you could choose to do that if you wanted to instead.
 
12. If I receive ETH or other cryptocurrency as a payment for my business, is this taxable?
Yes. Similar to mining, your income would be what the value of the coins you received was. This would also be your cost basis in the coins.
 
13. If I received Bitcoin Cash as a result of the hard fork on August 1, 2017, is this taxable?
Most likely yes. For example, if you owned 1 Bitcoin and received 1 Bitcoin Cash on August 1, 2017 as a result of the hard fork, your income would be the value of 1 Bitcoin Cash on that date. Bitcoin.tax uses a value of $277. This value would also be your cost basis in the position. Any other hard forks would probably be treated similarly. Airdrops may be treated similarly as well, in the IRS' view.
Here are a couple more good articles about reporting the Bitcoin Cash fork as taxable ordinary income. The second one goes into depth and cites a US Supreme Court decision as precedent: one, two
 
14. If I use ETH, BTC, or other cryptocurrency to purchase goods or services, is this a taxable transaction?
Yes. It would be treated as selling your cryptocurrency for USD, and then using that USD to purchase those goods or services. This is because the IRS treats cryptocurrency as property and not currency.
 
15. Are cryptocurrencies subject to the wash sale rule?
Probably not. Section 1091 only applies to stock or securities. Cryptocurrencies are not classified as stocks or securities. Therefore, you could sell your ETH at a loss, repurchase it immediately, and still realize this loss on your tax return, whereas you cannot do the same with a stock. Please see this link for more information.
 
16. What if I hold cryptocurrency on an exchange based outside of the US?
There are two separate foreign account reporting requirements: FBAR and FATCA.
A FBAR must be filed if you held more than $10,000 on an exchange based outside of the US at any point during the tax year.
A Form 8938 (FATCA) must be filed if you held more than $75,000 on an exchange based outside of the US at any point during the tax year, or more than $50,000 on the last day of the tax year.
The penalties are severe for not filing these two forms if you are required to. Please see the second half of this post for more information on foreign account reporting.
 
17. What are the tax implications of gifting cryptocurrency?
Small gifts of cryptocurrency do not have a tax implication for the gift giver or for the recipient. The recipient would retain the gift giver's old cost basis, so it could be a good idea for the gift giver to provide records of the original cost basis to the recipient as well (or else the recipient would have to assume a cost basis of $0 if the recipient ever sells the cryptocurrency).
Large gifts of cryptocurrency could start having gift and estate tax implications on the giver if the value exceeds more than $14,000 (in 2017) or $15,000 (in 2018) per year per recipient.
Here's a good article on Investopedia on this issue.
An important exception applies if the gift giver gives cryptocurrency that has a cost basis that is higher than the market value at the time of the gift. Please see the middle of this post for more information on that.
 
18. Where can I learn even more about cryptocurrency taxation?
Unchained Podcast: The Tax Rules That Have Crypto Users Aghast
IRS Notice 2014-21
Great reddit post from tax attorney Tyson Cross from 2014
 
19. Are there any websites that you recommend in helping me with all of this?
Yes - I have used bitcoin.tax and highly recommend it. You can import directly from an exchange to the website using API, and/or export a .csv/excel file from the exchange and import it into the website. The exchanges I successfully imported from were Coinbase, GDAX, Bittrex, and Binance. The result is a .csv or other file that you can import into your tax software.
I have also heard good things about cointracking.info but have not personally used it myself.
 
20. Taxation is theft!
I can't help you there.
 
 
That is the summary I have for now. There have been a lot of excellent cryptocurrency tax guides on reddit, such as this one, this one, and this one, but I wanted to post my short summary guide on ethtrader which hopefully answers some of the questions you all may have about US taxation of ETH and other cryptocurrencies. Please let me know if you have any more questions, and I’d be happy to answer them to the best of my ability. Thank you!
Regarding edits: I have made many edits to my post since I originally posted it. Please refresh to see the latest edits to my guide. Thank you.

Update: Hi /r/Bitcoin! I quit my job to start Cointaxes. Here to answer questions about taxes and digital currencies! I published a YouTube series on top questions, launched crypto tax tools and would love your input on ANY other topics or questions! :)

Hi /Bitcoin! Thank you for reading!
In the last two months since I posted here, my team and I have been hard at work trying to make everyone's lives a bit easier for cryptocurrency and tax. In fact, we will be able to launch some tools this summer that will help optimize your trades from a tax perspective - as you make them. We think there's a chance we could even make it tax advantageous to use crypto vs. fiat... more on that later. For now, we would love to get your feedback on what we're working on.
The TLDR: We made Cointaxes so you can estimate your tax liability and whether or not you have FINCEN obligations for free on our site. It was important to make this summary information free because our mission is create confidence and certainty around cryptocurrencies.
Please let me know if you have any questions or comments (I'll probably respond to every comment here!)
Watch a Cointaxes' YouTube Series answering the top questions How are cryptocurrencies taxed? Why should you pay this year? Am I taxed when I convert into fiat or pull money out of my exchanges? What about mining and airdrops? All this and more is covered!
We launched a tool to help measure your FINCEN requirements for FBAR & FATCA
In my last post, I mentioned a "fun" fact around FINCEN requirements. The media is talking about this more (i.e. CNBC - "How cryptocurrency investors could find themselves behind bars"). The good news is it's really simple for the ledger technology we built to check if you cross the $10,000 or $50,000 thresholds. On our site, Cointaxes, you can add your exchanges and then check if you have crossed the threshold. Importantly, we wanted to make this critical information available for free. Particularly because the the deadline is April 15.
If you fail to file the FBAR, the deadline will be extended to October 15. You can read more about this on official government sites General FBAR information, FBAR FAQS (not super helpful IMO) and the online form itself.
About Cointaxes
Cointaxes was formed and funded with the mission to establish confidence and certainty around cryptocurrency. We have a base tax preparation tool with support for Coinbase, GDAX, Binance, Bittrex, Poloniex, and Kraken.
We made Cointaxes so you can estimate your tax liability and whether or not you have FINCEN obligations for free on our site. Your detailed reports or Form 8949 for tax filing is behind a modest paywall compared to what we've seen other tools out there charging.
We see global adoption of digital currencies as an inevitability. The uncertainty lies in how effectively and smoothly this once-in-a-lifetime shift occurs. As a tax preparation service, we have a special seat in the cryptocurrency ecosystem directly related to this uncertainty: it is our job to help both citizens and governments around the world understand how to use and treat digital currencies.
If our mission excites you
Newsletter update
If you want to stay on top of regulatory and tax related crypto news (as well as when we roll out shiny new tools) then consider subscribing to our newsletter.
If you signed up for our newsletter two months ago - sorry for the lack of content! We've been too focused on trying to get this product up and running in time for the deadline (barely made it!) We recently expanded our team and will be able to be much more consistent about the content we're creating!
Important Disclaimers: For this post and any of my replies to your questions below... this is not tax advice and should not be relied upon for making any tax decisions. We always recommend speaking to a tax professional before making decisions related to your taxes and our guides are not a substitute for tax advice.

A Beginners Guide to Bitcoin, Blockchain & Cryptocurrency

As cryptocurrency, and blockchain technology become more abundant throughout our society, it’s important to understand the inner workings of this technology, especially if you plan to use cryptocurrency as an investment vehicle. If you’re new to the crypto-sphere, learning about Bitcoin makes it much easier to understand other cryptocurrencies as many other altcoins' technologies are borrowed directly from Bitcoin.
Bitcoin is one of those things that you look into only to discover you have more questions than answers, and right as you’re starting to wrap your head around the technology; you discover the fact that Bitcoin has six other variants (forks), the amount of politics at hand, or that there are over a thousand different cryptocurrencies just as complex if not even more complex than Bitcoin.
We are currently in the infancy of blockchain technology and the effects of this technology will be as profound as the internet. This isn’t something that’s just going to fade away into history as you may have been led to believe. I believe this is something that will become an integral part of our society, eventually embedded within our technology. If you’re a crypto-newbie, be glad that you're relatively early to the industry. I hope this post will put you on the fast-track to understanding Bitcoin, blockchain, and how a large percentage of cryptocurrencies work.

Community Terminology

Altcoin: Short for alternative coin. There are over 1,000 different cryptocurrencies. You’re probably most familiar with Bitcoin. Anything that isn’t Bitcoin is generally referred to as an altcoin.
HODL: Misspelling of hold. Dank meme accidentally started by this dude. Hodlers are much more interested in long term gains rather than playing the risky game of trying to time the market.
TO THE MOON: When a cryptocurrency’s price rapidly increases. A major price spike of over 1,000% can look like it’s blasting off to the moon. Just be sure you’re wearing your seatbelt when it comes crashing down.
FUD: Fear. Uncertainty. Doubt.
FOMO: Fear of missing out.
Bull Run: Financial term used to describe a rising market.
Bear Run: Financial term used to describe a falling market.

What Is Bitcoin?

Bitcoin (BTC) is a decentralized digital currency that uses cryptography to secure and ensure validity of transactions within the network. Hence the term crypto-currency. Decentralization is a key aspect of Bitcoin. There is no CEO of Bitcoin or central authoritative government in control of the currency. The currency is ran and operated by the people, for the people. One of the main development teams behind Bitcoin is blockstream.
Bitcoin is a product of blockchain technology. Blockchain is what allows for the security and decentralization of Bitcoin. To understand Bitcoin and other cryptocurrencies, you must understand to some degree, blockchain. This can get extremely technical the further down the rabbit hole you go, and because this is technically a beginners guide, I’m going to try and simplify to the best of my ability and provide resources for further technical reading.

A Brief History

Bitcoin was created by Satoshi Nakamoto. The identity of Nakamoto is unknown. The idea of Bitcoin was first introduced in 2008 when Nakamoto released the Bitcoin white paper - Bitcoin: A Peer-to-Peer Electronic Cash System. Later, in January 2009, Nakamoto announced the Bitcoin software and the Bitcoin network officially began.
I should also mention that the smallest unit of a Bitcoin is called a Satoshi. 1 BTC = 100,000,000 Satoshis. When purchasing Bitcoin, you don’t actually need to purchase an entire coin. Bitcoin is divisible, so you can purchase any amount greater than 1 Satoshi (0.00000001 BTC).

What Is Blockchain?

Blockchain is a distributed ledger, a distributed collection of accounts. What is being accounted for depends on the use-case of the blockchain itself. In the case of Bitcoin, what is being accounted for is financial transactions.
The first block in a blockchain is referred to as the genesis block. A block is an aggregate of data. Blocks are also discovered through a process known as mining (more on this later). Each block is cryptographically signed by the previous block in the chain and visualizing this would look something akin to a chain of blocks, hence the term, blockchain.
For more information regarding blockchain I’ve provided more resouces below:

What is Bitcoin Mining

Bitcoin mining is one solution to the double spend problem. Bitcoin mining is how transactions are placed into blocks and added onto the blockchain. This is done to ensure proof of work, where computational power is staked in order to solve what is essentially a puzzle. If you solve the puzzle correctly, you are rewarded Bitcoin in the form of transaction fees, and the predetermined block reward. The Bitcoin given during a block reward is also the only way new Bitcoin can be introduced into the economy. With a halving event occurring roughly every 4 years, it is estimated that the last Bitcoin block will be mined in the year 2,140. (See What is Block Reward below for more info).
Mining is one of those aspects of Bitcoin that can get extremely technical and more complicated the further down the rabbit hole you go. An entire website could be created (and many have) dedicated solely to information regarding Bitcoin mining. The small paragraph above is meant to briefly expose you to the function of mining and the role it plays within the ecosystem. It doesn’t even scratch the surface regarding the topic.

How do you Purchase Bitcoin?

The most popular way to purchase Bitcoin through is through an online exchange where you trade fiat (your national currency) for Bitcoin.
Popular exchanges include:
  • Coinbase
  • Kraken
  • Cex
  • Gemini
There’s tons of different exchanges. Just make sure you find one that supports your national currency.

Volatility

Bitcoin and cryptocurrencies are EXTREMELY volatile. Swings of 30% or more within a few days is not unheard of. Understand that there is always inherent risks with any investment. Cryptocurrencies especially. Only invest what you’re willing to lose.

Transaction & Network Fees

Transacting on the Bitcoin network is not free. Every purchase or transfer of Bitcoin will cost X amount of BTC depending on how congested the network is. These fees are given to miners as apart of the block reward.
Late 2017 when Bitcoin got up to $20,000USD, the average network fee was ~$50. Currently, at the time of writing this, the average network fee is $1.46. This data is available in real-time on BitInfoCharts.

Security

In this new era of money, there is no central bank or government you can go to in need of assistance. This means the responsibility of your money falls 100% into your hands. That being said, the security regarding your cryptocurrency should be impeccable. The anonymity provided by cryptocurrencies alone makes you a valuable target to hackers and scammers. Below I’ve detailed out best practices regarding securing your cryptocurrency.

Two-Factor Authentication (2FA)

Two-factor authentication is a second way of authenticating your identity upon signing in to an account. Most cryptocurrency related software/websites will offer or require some form of 2FA. Upon creation of any crypto-related account find the Security section and enable 2FA.

SMS Authentication

The most basic form of 2FA which you are probably most familiar with. This form of authentication sends a text message to your smartphone with a special code that will allow access to your account upon entry. Note that this is not the safest form of 2FA as you may still be vulnerable to what is known as a SIM swap attack. SIM swapping is a social engineering method in which an attacker will call up your phone carrier, impersonating you, in attempt to re-activate your SIM card on his/her device. Once the attacker has access to your SIM card he/she now has access to your text messages which can then be used to access your online accounts. You can prevent this by using an authenticator such as Google Authenticator.

Authenticator

The use of an authenticator is the safest form of 2FA. An authenticator is installed on a seperate device and enabling it requires you input an ever changing six digit code in order to access your account. I recommend using Google Authenticator.
If a website has the option to enable an authenticator, it will give you a QR code and secret key. Use Google Authenticator to scan the QR code. The secret key consists of a random string of numbers and letters. Write this down on a seperate sheet of paper and do not store it on a digital device.
Once Google Authenticator has been enabled, every time you sign into your account, you will have to input a six-digit code that looks similar to this. If you happen to lose or damage the device you have Google Authenticator installed on, you will be locked out of your account UNLESS you have access to the secret key (which you should have written down).

Hardware Wallets

A wallet is what you store Bitcoin and cryptocurrency on. I’ll provide resources on the different type of wallets later but I want to emphasize the use of a hardware wallet (aka cold storage).
Hardware wallets are the safest way of storing cryptocurrency because it allows for your crypto to be kept offline in a physical device. After purchasing crypto via an exchange, I recommend transferring it to cold storage. The most popular hardware wallets include the Ledger Nano S, and Trezor.
Hardware wallets come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key as well as any other sensitive information in a safety deposit box.
I know this all may seem a bit manic, but it is important you take the necessary security precautions in order to ensure the safety & longevity of your cryptocurrency.

Technical Aspects of Bitcoin

TL;DR
  • Address: What you send Bitcoin to.
  • Wallet: Where you store your Bitcoin
  • Max Supply: 21 million
  • Block Time: ~10 minutes
  • Block Size: 1-2 MB
  • Block Reward: BTC reward received from mining.

What is a Bitcoin Address?

A Bitcoin address is what you send Bitcoin to. If you want to receive Bitcoin you’d give someone your Bitcoin address. Think of a Bitcoin address as an email address for money.

What is a Bitcoin Wallet?

As the title implies, a Bitcoin wallet is anything that can store Bitcoin. There are many different types of wallets including paper wallets, software wallets and hardware wallets. It is generally advised NOT to keep cryptocurrency on an exchange, as exchanges are prone to hacks (see Mt. Gox hack).
My preferred method of storing cryptocurrency is using a hardware wallet such as the Ledger Nano S or Trezor. These allow you to keep your crypto offline in physical form and as a result, much more safe from hacks. Paper wallets also allow for this but have less functionality in my opinion.
After I make crypto purchases, I transfer it to my Ledger Nano S and keep that in a safe at home. Hardware wallets also come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key in a safety deposit box.

What is Bitcoins Max Supply?

The max supply of Bitcoin is 21 million. The only way new Bitcoins can be introduced into the economy are through block rewards which are given after successfully mining a block (more on this later).

What is Bitcoins Block Time?

The average time in which blocks are created is called block time. For Bitcoin, the block time is ~10 minutes, meaning, 10 minutes is the minimum amount of time it will take for a Bitcoin transaction to be processed. Note that transactions on the Bitcoin network can take much longer depending on how congested the network is. Having to wait a few hours or even a few days in some instances for a transaction to clear is not unheard of.
Other cryptocurrencies will have different block times. For example, Ethereum has a block time of ~15 seconds.
For more information on how block time works, Prabath Siriwardena has a good block post on this subject which can be found here.

What is Bitcoins Block Size?

There is a limit to how large blocks can be. In the early days of Bitcoin, the block size was 36MB, but in 2010 this was reduced to 1 MB in order to prevent distributed denial of service attacks (DDoS), spam, and other malicious use on the blockchain. Nowadays, blocks are routinely in excess of 1MB, with the largest to date being somewhere around 2.1 MB.
There is much debate amongst the community on whether or not to increase Bitcoin’s block size limit to account for ever-increasing network demand. A larger block size would allow for more transactions to be processed. The con argument to this is that decentralization would be at risk as mining would become more centralized. As a result of this debate, on August 1, 2017, Bitcoin underwent a hard-fork and Bitcoin Cash was created which has a block size limit of 8 MB. Note that these are two completely different blockchains and sending Bitcoin to a Bitcoin Cash wallet (or vice versa) will result in a failed transaction.
Update: As of May 15th, 2018 Bitcoin Cash underwent another hard fork and the block size has increased to 32 MB.
On the topic of Bitcoin vs Bitcoin Cash and which cryptocurrency is better, I’ll let you do your own research and make that decision for yourself. It is good to know that this is a debated topic within the community and example of the politics that manifest within the space. Now if you see community members arguing about this topic, you’ll at least have a bit of background to the issue.

What is Block Reward?

Block reward is the BTC you receive after discovering a block. Blocks are discovered through a process called mining. The only way new BTC can be added to the economy is through block rewards and the block reward is halved every 210,000 blocks (approximately every 4 years). Halving events are done to limit the supply of Bitcoin. At the inception of Bitcoin, the block reward was 50BTC. At the time of writing this, the block reward is 12.5BTC. Halving events will continue to occur until the amount of new Bitcoin introduced into the economy becomes less than 1 Satoshi. This is expected to happen around the year 2,140. All 21 million Bitcoins will have been mined. Once all Bitcoins have been mined, the block reward will only consist of transaction fees.

Technical Aspects Continued

Understanding Nodes

Straight from the Bitcoin.it wiki
Any computer that connects to the Bitcoin network is called a node. Nodes that fully verify all of the rules of Bitcoin are called full nodes.
In other words, full nodes are what verify the Bitcoin blockchain and they play a crucial role in maintaining the decentralized network. Full nodes store the entirety of the blockchain and validate transactions. Anyone can participate in the Bitcoin network and run a full node. Bitcoin.org has information on how to set up a full node. Running a full node also gives you wallet capabilities and the ability to query the blockchain.
For more information on Bitcoin nodes, see Andreas Antonopoulos’s Q&A on the role of nodes.

What is a Fork?

A fork is a divergence in a blockchain. Since Bitcoin is a peer-to-peer network, there’s an overall set of rules (protocol) in which participants within the network must abide by. These rules are put in place to form network consensus. Forks occur when implementations must be made to the blockchain or if there is disagreement amongst the network on how consensus should be achieved.

Soft Fork vs Hard Fork

The difference between soft and hard forks lies in compatibility. Soft forks are backwards compatible, hard forks are not. Think of soft forks as software upgrades to the blockchain, whereas hard forks are a software upgrade that warrant a completely new blockchain.
During a soft fork, miners and nodes upgrade their software to support new consensus rules. Nodes that do not upgrade will still accept the new blockchain.
Examples of Bitcoin soft forks include:
A hard fork can be thought of as the creation of a new blockchain that X percentage of the community decides to migrate too. During a hard fork, miners and nodes upgrade their software to support new consensus rules, Nodes that do not upgrade are invalid and cannot accept the new blockchain.
Examples of Bitcoin hard forks include:
  • Bitcoin Cash
  • Bitcoin Gold
Note that these are completely different blockchains and independent from the Bitcoin blockchain. If you try to send Bitcoin to one of these blockchains, the transaction will fail.

A Case For Bitcoin in a World of Centralization

Our current financial system is centralized, which means the ledger(s) that operate within this centralized system are subjugated to control, manipulation, fraud, and many other negative aspects that come with this system. There are also pros that come with a centralized system, such as the ability to swiftly make decisions. However, at some point, the cons outweigh the pros, and change is needed. What makes Bitcoin so special as opposed to our current financial system is that Bitcoin allows for the decentralized transfer of money. Not one person owns the Bitcoin network, everybody does. Not one person controls Bitcoin, everybody does. A decentralized system in theory removes much of the baggage that comes with a centralized system. Not to say the Bitcoin network doesn’t have its problems (wink wink it does), and there’s much debate amongst the community as to how to go about solving these issues. But even tiny steps are significant steps in the world of blockchain, and I believe Bitcoin will ultimately help to democratize our financial system, whether or not you believe it is here to stay for good.

Final Conclusions

Well that was a lot of words… Anyways I hope this guide was beneficial, especially to you crypto newbies out there. You may have come into this realm not expecting there to be an abundance of information to learn about. I know I didn’t. Bitcoin is only the tip of the iceberg, but now that you have a fundamental understanding of Bitcoin, learning about other cryptocurrencies such as Litecoin, and Ethereum will come more naturally.
Feel free to ask questions below! I’m sure either the community or myself would be happy to answer your questions.
Thanks for reading!

I wrote a 30,000 ft. "executive summary" intro document for cryptos. Not for you, for your non-technical parents or friends.

This document was originally written for my dad, an intelligent guy who was utterly baffled about the cryptocurrency world. The aim was to be extremely concise, giving a broad overview of the industry and some popular coins while staying non-technical. For many of you there will be nothing new here, but recognize that you are in the 0.001% of the population heavily into crypto technology.
I've reproduced it for Reddit below, or you can find the original post here on my website. Download the PDF there or hit the direct link: .PDF version.
Donations happily accepted:
ETH: 0x4e03Bf5CCE3eec4Ddae4d3d6aAD46ca4f198AeD6 BTC: 1GqWMZRRygRJJWYYTWHkAVoRcgyQHjgBMZ XMR: 42Y1S1KBoPk381kc7hA68zaiC78BxMoCADjLrFcTdWiE7ejhZc49s1t9i7P2EmTnHsLDiKoSUiogCbLVHXRJxjrCT4WG8ic XRB: xrb_1bpzh745s9kzk8ymfnks3jtdi65ayumdstokzd4yw4ohu3fopxmiocjcntcu 

Background

This document is purely informational. At the time of writing there are over 1000 cryptocurrencies (“cryptos”) in a highly volatile, high risk market. Many of the smaller “altcoins” require significant technical knowledge to store and transact safely. I advise you to carefully scrutinize each crypto’s flavor of blockchain, potential utility, team of developers, and guiding philosophy, before making any investment [1] decisions. With that out of the way, what follows are brief, extremely high-level summaries of some cryptos which have my interest, listed in current market cap order. But first, some info:
Each crypto is a different implementation of a blockchain network. Originally developed as decentralized digital cash, these technologies have evolved into much broader platforms, powering the future of decentralized applications across every industry in the global economy. Without getting into the weeds, [2] most cryptos work on similar principles:
Distributed Ledgers Each node on a blockchain network has a copy of every transaction, which enables a network of trust that eliminates fraud. [3]
Decentralized “Miners” comprise the infrastructure of a blockchain network. [4] They are monetarily incentivized to add computing power to the network, simultaneously securing and processing each transaction. [5]
Peer-to-peer Cryptos act like digital cash-- they require no third party to transact and are relatively untraceable. Unlike cash, you can back them up.
Global Transactions are processed cheaply and instantly, anywhere on Earth. Using cryptos, an African peasant and a San Francisco engineer have the same access to capital, markets, and network services.
Secure Blockchains are predicated on the same cryptographic technology that secures your sensitive data and government secrets. They have passed seven years of real-world penetration testing with no failures. [6]

Bitcoin (BTC)

The first cryptocurrency. As with first movers in any technology, there are associated pros and cons. Bitcoin has by far the strongest brand recognition and deepest market penetration, and it is the only crypto which can be used directly as a currency at over 100,000 physical and web stores around the world. In Venezuela and Zimbabwe, where geopolitical events have created hyperinflation in the centralized fiat currency, citizens have moved to Bitcoin as a de facto transaction standard. [7]
However, Bitcoin unveiled a number of issues that have been solved by subsequent cryptos. It is experiencing significant scaling issues, resulting in high fees and long confirmation times. The argument over potential solutions created a rift in the Bitcoin developer community, who “forked” the network into two separate blockchains amidst drama and politicking in October 2017. Potential solutions to these issues abound, with some already in place, and others nearing deployment.
Bitcoin currently has the highest market cap, and since it is easy to buy with fiat currency, the price of many smaller cryptos (“altcoins”) are loosely pegged to its price. This will change in the coming year(s).

Ethereum (ETH)

Where Bitcoin is a currency, Ethereum is a platform, designed as a foundational protocol on which to develop decentralized applications (“Dapps”). Anyone can write code and deploy their program on the global network for extremely low fees. Just like Twitter wouldn’t exist without the open platform of the internet, the next world-changing Dapp can’t exist without Ethereum.
Current Dapps include a global market for idle computing power and storage, peer-to-peer real estate transactions (no trusted third party for escrow), identity networks for governments and corporations (think digital Social Security card), and monetization strategies for the internet which replace advertising. Think back 10 years to the advent of smartphones, and then to our culture today-- Ethereum could have a similar network effect on humanity.
Ethereum is currently the #2 market cap crypto below Bitcoin, and many believe it will surpass it in 2018. It has a large, active group of developers working to solve scaling issues, [8] maintain security, and create entirely new programming conventions. If successful, platforms like Ethereum may well be the foundation of the decentralized internet of the future.

Ripple (XRP)

Ripple is significantly more centralized than most crypto networks, designed as a backbone for the global banking and financial technology (“fintech”) industries. It is a network for exchanging between fiat currencies and other asset classes instantly and cheaply, especially when transacting cross-border and between separate institutions. It uses large banks and remittance companies as “anchors” to allow trading between any asset on the network, and big names like Bank of America, American Express, RBC, and UBS are partners. The utility of this network is global and massive in scale.
It is extremely important to note that not all cryptos have the same number of tokens. Ripple has 100 Billion tokens compared to Bitcoin’s 21 Million. Do not directly compare price between cryptos. XRP will likely never reach $1k, [9] but the price will rise commensurate with its utility as a financial tool.
In some sense, Ripple is anathema to the original philosophical vision of this technology space. And while I agree with the cyberpunk notion of decentralized currencies, separation of money and state, this is the natural progression of the crypto world. The internet was an incredible decentralized wild west of Usenet groups and listservs before Eternal September and the dot-com boom, but its maturation affected every part of global society.

Cardano (ADA)

Cardano’s main claim to fame: it is the only crypto developed using academic methodologies by a global collective of engineers and researchers, built on a foundation of industry-leading, peer-reviewed cryptographic research. The network was designed from first-principles to allow scalability, system upgrades, and to balance the privacy of its users with the security needs of regulators.
One part of this ecosystem is the Cardano Foundation, a Swiss non-profit founded to work proactively with governments and regulatory bodies to institute legal frameworks around the crypto industry. Detractors of Cardano claim that it doesn’t do anything innovative, but supporters see the academic backing and focus on regulation development as uniquely valuable.

Stellar Lumens (XLM)

Stellar Lumens and Ripple were founded by the same person. They initially shared the same code, but today the two are distinct in their technical back-end as well as their guiding philosophy and development goals. Ripple is closed-source, for-profit, deflationary, and intended for use by large financial institutions. Stellar is open-source, non-profit, inflationary, and intended to promote international wealth distribution. As such, they are not direct competitors.
IBM is a major partner to Stellar. Their network is already processing live transactions in 12 currency corridors across the South Pacific, with plans to process 60% of all cross-border payments in the South Pacific’s retail foreign exchange corridor by Q2 2018.
Beyond its utility as a financial tool, the Stellar network may become a competitor to Ethereum as a platform for application development and Initial Coin Offerings (“ICOs”). The theoretical maximum throughput for the network is higher, and it takes less computational power to run. The Stellar development team is highly active, has written extensive documentation for third-party developers, and has an impressive list of advisors, including Patrick Collison (Stripe), Sam Altman (Y Combinator), and other giants in the software development community.

Iota (IOT)

Iota was developed as the infrastructure backbone for the Internet of Things (IoT), sometimes called the machine economy. As the world of inanimate objects is networked together, their need to communicate grows exponentially. Fridges, thermostats, self-driving cars, printers, planes, and industrial sensors all need a secure protocol with which to transact information.
Iota uses a “Tangle” instead of a traditional blockchain, and this is the main innovation driving the crypto’s value. Each device that sends a transaction confirms two other transactions in the Tanlge. This removes the need for miners, and enables unique features like zero fees and infinite scalability. The supply of tokens is fixed forever at 2.8*1015, a staggeringly large number (almost three thousand trillion), and the price you see reported is technically “MIOT”, or the price for a million tokens.

Monero (XMR)

The most successful privacy-focused cryptocurrency. In Bitcoin and most other cryptos, anyone can examine the public ledger and trace specific coins through the network. If your identity can be attached to a public address on that network, an accurate picture of your transaction history can be built-- who, what, and when. Monero builds anonymity into the system using strong cryptographic principles, which makes it functionally impossible to trace coins, [10] attach names to wallets, or extract metadata from transactions. The development team actively publishes in the cryptography research community.
Anonymous transactions are not new-- we call it cash. Only in the past two decades has anonymity grown scarce in the first-world with the rise of credit cards and ubiquitous digital records. Personal data is becoming the most valuable resource on Earth, and there are many legitimate reasons for law-abiding citizens to want digital privacy, but it is true that with anonymity comes bad actors-- Monero is the currency of choice for the majority of black market (“darknet”) transactions. Similarly, US Dollars are the main vehicle for the $320B annual drug trade. An investment here should be based on the underlying cryptographic research and technology behind this coin, as well as competitors like Zcash. [11]

RaiBlocks (XRB)

Zero fees and instantaneous transfer make RaiBlocks extremely attractive for exchange of value, in many senses outperforming Bitcoin at its original intended purpose. This crypto has seen an explosion in price and exposure over the past month, and it may become the network of choice for transferring value within and between crypto exchanges.
Just in the first week of 2018: the CEO of Ledger (makers of the most popular hardware wallet on the market) waived the $50k code review fee to get RaiBlocks on his product, and XRB got listed on Binance and Kucoin, two of the largest altcoin exchanges globally. This is one to watch for 2018. [12]

VeChain (VEN)

Developed as a single answer to the problem of supply-chain logistics, VeChain is knocking on the door of a fast-growing $8 trillion industry. Every shipping container and packaged product in the world requires constant tracking and verification. A smart economy for logistics built on the blockchain promises greater efficiency and lower cost through the entire process flow.
Don’t take my word for it-- VeChain has investment from PwC (5th largest US corporation), Groupe Renault, Kuehne & Nagel (world’s largest freight company), and DIG (China’s largest wine importer). The Chinese government has mandated VeChain to serve as blockchain technology partner to the city of Gui’an, a special economic zone and testbed for China’s smart city of the future. This crypto has some of the strongest commercial partnerships in the industry, and a large active development team.
  1. “Investment” is a misnomer. Cryptos are traded like securities, but grant you no equity (like trading currency).
  2. The weeds for Bitcoin: basic intro (1:36), non-technical explanation (5:24), Bitcoin 101 – Andreas Antonopoulos (23:51).
  3. It is impossible to double-spend or create a fake transaction, as each ledger is confirmed against every other ledger.
  4. Some utility token blockchains use DAG networks or similar non-linear networks which don’t require mining.
  5. In practice, these are giant warehouses full of specialized computers constantly processing transactions. Miners locate to the cheapest electricity source, and the bulk of mining currently occurs in China.
  6. Centralized second-layer exchange websites have been hacked, but the core technology is untouched.
  7. This effect has been termed "bitcoinization".
  8. The Ethereum roadmap shows moving from a Proof of Work (PoW) to Proof of Stake (PoS) consensus model.
  9. At $2.62 per XRP token, Ripple already commands a $100B market cap.
  10. After a January 2017 update.
  11. Monero uses ring signatures while Zcash uses ZK-SNARKs to create anonymity. Both have pros and cons.
  12. Note: all signs point to this crypto being renamed “Nano” in the coming weeks: nano.co.

Welcome to Komodo. A Beginner's Guide.

Overview: the basics of the Komodo ecosystem.
 
1. Privacy: a mighty privacy coin that protects your data and rewards you 5% annually.
 
What is a privacy coin? Privacy coins implement various protocols to create a layer of privacy between blockchain transactions. This can be utilized to prevent blockchain traceability or provide different levels of privacy for data stored on the blockchain.
 
What is Jumblr? A decentralized cryptocurrency shuffler that allows your transactions to become incognito and protects them from being traced through a time or knapsack attack. It adds a privacy layer to your transactions because after your coins are Jumbled, an analysis of the amounts that went in or times that they came out is futile. This function is unique to Komodo and does not require third parties.
 
2. Security: a secure and robust consensus mechanism called delayed Proof of Work (dPoW) that protects your funds and our ecosystem. This unique technology uses a notarization process to create a backup of the entire Komodo blockchain onto the Bitcoin blockchain thereby increasing security and resilience. This happens roughly every ten minutes. The backups are then saved (notarized) onto the Bitcoin blockchain because it has the highest hashrate available. So even if Komodo suffered a devastating attack (which is extremely unlikely), the Komodo blockchain would merely revert to the most recently notarized copy of the chain. If Bitcoin loses superiority in terms of hashrate the dPOW mechanism can be switched to another blockchain on demand. Hence, Komodo is the most flexible platform to build on and one of the most secure.
 
What is hashrate? A proof of work blockchain needs a lot of calculations. Hashrate is the way it is measured. The amount of data hashed in a given time by a machine. It is a unit used to define the amount of calculations made by a machine. When you add all the machines together you have the hashrate for that blockchain (here’s a great chart that illustrates it). It's like a river of transactions and the broader and wider it is, the harder it is to manipulate it.
 
Hashrate historical chart: https://bitinfocharts.com/comparison/hashrate-btc-eth-bch-ltc.html#1y.
 
3. Freedom from middlemen: a decentralized exchange (DEX) called BarterDEX, with a fully working order book, powered by our world-class atomic swap technology. This reduces risk and transaction fees. Komodo’s atomic swaps work between Bitcoin protocol and ERC20 tokens which means we can support over 95% of all the tokens and coins in existence. Our decentralized exchange offers ‘liquidity power-ups’ which mean that you can place more than one buy order with the same funds (i.e. pick your top 5 coins and if any of them drop below 50% of their value you’ll buy it and cancel the other orders at the same time) which means your funds have a greater value! On top of all that, Komodo’s DEX has fast transaction speeds and super low transaction fees (0.15%). You can find live BarterDEX and Komodo Stats here: https://dexstats.info/index.php.
 
What are atomic swaps? Atomic swaps are a method of trading cryptocurrencies peer-to-peer, directly from one blockchain to another, without the need to trust a third-party. Here is a good article to read that will take you about 11 minutes ‘Atomic Swaps & Etomic Swaps, Explained in Plain English’ written by John Westbrook on Medium.
 
Why do YOU want an exchange to be decentralized? A centralized exchange is a third party and requires you to trust them with your funds. If they’re hacked you’re at risk of losing your funds. Centralized exchanges also require you to trade between pillars (i.e. BTC or USDT) which can involve higher transaction fees and a greater number of trades than necessary to swap the token you have for the one you want (i.e. DOGE sell to BTC to buy KMD is two trades when all you really want is DOGE to KMD).
 
4. Independence: decentralized ICO crowdfunding and scalability solutions for blockchain startups.
You can think of a blockchain as a motorway and if you build a project on the same blockchain as other projects you will be impacted by how well the other drives behave, or by the motorway introducing tolls, or you could suffer from congestion (i.e. if you’re familiar with how crypto kitties caused ETH transaction fees to greatly increase and transaction speeds to slow down then you’ll understand multiple projects on one blockchain cause a scalability and independence problem ).
Komodo offers parallel chains which mean a project or decentralized ICO is given its own chain which uses Komodo’s technology. This also solves the scalability issue because using the motorway analogy we can simply open more lanes for a project with a high amount of congestion. This is possible because of the dPOW notarisation. It allows projects to launch completely independent blockchains.
Every independent blockchain created on Komodo Platform is automatically integrated into Komodo’s BarterDEX (DEX) which means they have instant access to liquidity for their token and their community can buy and trade immediately. If you compare this to a centralized exchange where projects are often met with a list of onerous demands and fees to be listed and risk being delisted then you’ll understand how important this is for any project especially smaller teams and decentralized apps (dAPPS).
 
5. Universal Wallet: the Agama Wallet is a universal secure, multi-coin wallet to store funds on and claim the 5% reward for your $KMD tokens. There is also a paper wallet available if you would prefer a cold storage option for those who want to maximize their security.
