Technical: A Brief History of Payment Channels: from Satoshi to Lightning Network

Who cares about political tweets from some random country's president when payment channels are a much more interesting and are actually capable of carrying value?
So let's have a short history of various payment channel techs!

Generation 0: Satoshi's Broken nSequence Channels

Because Satoshi's Vision included payment channels, except his implementation sucked so hard we had to go fix it and added RBF as a by-product.
Originally, the plan for nSequence was that mempools would replace any transaction spending certain inputs with another transaction spending the same inputs, but only if the nSequence field of the replacement was larger.
Since 0xFFFFFFFF was the highest value that nSequence could get, this would mark a transaction as "final" and not replaceable on the mempool anymore.
In fact, this "nSequence channel" I will describe is the reason why we have this weird rule about nLockTime and nSequence. nLockTime actually only works if nSequence is not 0xFFFFFFFF i.e. final. If nSequence is 0xFFFFFFFF then nLockTime is ignored, because this if the "final" version of the transaction.
So what you'd do would be something like this:
  1. You go to a bar and promise the bartender to pay by the time the bar closes. Because this is the Bitcoin universe, time is measured in blockheight, so the closing time of the bar is indicated as some future blockheight.
  2. For your first drink, you'd make a transaction paying to the bartender for that drink, paying from some coins you have. The transaction has an nLockTime equal to the closing time of the bar, and a starting nSequence of 0. You hand over the transaction and the bartender hands you your drink.
  3. For your succeeding drink, you'd remake the same transaction, adding the payment for that drink to the transaction output that goes to the bartender (so that output keeps getting larger, by the amount of payment), and having an nSequence that is one higher than the previous one.
  4. Eventually you have to stop drinking. It comes down to one of two possibilities:
    • You drink until the bar closes. Since it is now the nLockTime indicated in the transaction, the bartender is able to broadcast the latest transaction and tells the bouncers to kick you out of the bar.
    • You wisely consider the state of your liver. So you re-sign the last transaction with a "final" nSequence of 0xFFFFFFFF i.e. the maximum possible value it can have. This allows the bartender to get his or her funds immediately (nLockTime is ignored if nSequence is 0xFFFFFFFF), so he or she tells the bouncers to let you out of the bar.
Now that of course is a payment channel. Individual payments (purchases of alcohol, so I guess buying coffee is not in scope for payment channels). Closing is done by creating a "final" transaction that is the sum of the individual payments. Sure there's no routing and channels are unidirectional and channels have a maximum lifetime but give Satoshi a break, he was also busy inventing Bitcoin at the time.
Now if you noticed I called this kind of payment channel "broken". This is because the mempool rules are not consensus rules, and cannot be validated (nothing about the mempool can be validated onchain: I sigh every time somebody proposes "let's make block size dependent on mempool size", mempool state cannot be validated by onchain data). Fullnodes can't see all of the transactions you signed, and then validate that the final one with the maximum nSequence is the one that actually is used onchain. So you can do the below:
  1. Become friends with Jihan Wu, because he owns >51% of the mining hashrate (he totally reorged Bitcoin to reverse the Binance hack right?).
  2. Slip Jihan Wu some of the more interesting drinks you're ordering as an incentive to cooperate with you. So say you end up ordering 100 drinks, you split it with Jihan Wu and give him 50 of the drinks.
  3. When the bar closes, Jihan Wu quickly calls his mining rig and tells them to mine the version of your transaction with nSequence 0. You know, that first one where you pay for only one drink.
  4. Because fullnodes cannot validate nSequence, they'll accept even the nSequence=0 version and confirm it, immutably adding you paying for a single alcoholic drink to the blockchain.
  5. The bartender, pissed at being cheated, takes out a shotgun from under the bar and shoots at you and Jihan Wu.
  6. Jihan Wu uses his mystical chi powers (actually the combined exhaust from all of his mining rigs) to slow down the shotgun pellets, making them hit you as softly as petals drifting in the wind.
  7. The bartender mutters some words, clothes ripping apart as he or she (hard to believe it could be a she but hey) turns into a bear, ready to maul you for cheating him or her of the payment for all the 100 drinks you ordered from him or her.
  8. Steely-eyed, you stand in front of the bartender-turned-bear, daring him to touch you. You've watched Revenant, you know Leonardo di Caprio could survive a bear mauling, and if some posh actor can survive that, you know you can too. You make a pose. "Drunken troll logic attack!"
  9. I think I got sidetracked here.
Lessons learned?

Spilman Channels

Incentive-compatible time-limited unidirectional channel; or, Satoshi's Vision, Fixed (if transaction malleability hadn't been a problem, that is).
Now, we know the bartender will turn into a bear and maul you if you try to cheat the payment channel, and now that we've revealed you're good friends with Jihan Wu, the bartender will no longer accept a payment channel scheme that lets one you cooperate with a miner to cheat the bartender.
Fortunately, Jeremy Spilman proposed a better way that would not let you cheat the bartender.
First, you and the bartender perform this ritual:
  1. You get some funds and create a transaction that pays to a 2-of-2 multisig between you and the bartender. You don't broadcast this yet: you just sign it and get its txid.
  2. You create another transaction that spends the above transaction. This transaction (the "backoff") has an nLockTime equal to the closing time of the bar, plus one block. You sign it and give this backoff transaction (but not the above transaction) to the bartender.
  3. The bartender signs the backoff and gives it back to you. It is now valid since it's spending a 2-of-2 of you and the bartender, and both of you have signed the backoff transaction.
  4. Now you broadcast the first transaction onchain. You and the bartender wait for it to be deeply confirmed, then you can start ordering.
The above is probably vaguely familiar to LN users. It's the funding process of payment channels! The first transaction, the one that pays to a 2-of-2 multisig, is the funding transaction that backs the payment channel funds.
So now you start ordering in this way:
  1. For your first drink, you create a transaction spending the funding transaction output and sending the price of the drink to the bartender, with the rest returning to you.
  2. You sign the transaction and pass it to the bartender, who serves your first drink.
  3. For your succeeding drinks, you recreate the same transaction, adding the price of the new drink to the sum that goes to the bartender and reducing the money returned to you. You sign the transaction and give it to the bartender, who serves you your next drink.
  4. At the end:
    • If the bar closing time is reached, the bartender signs the latest transaction, completing the needed 2-of-2 signatures and broadcasting this to the Bitcoin network. Since the backoff transaction is the closing time + 1, it can't get used at closing time.
    • If you decide you want to leave early because your liver is crying, you just tell the bartender to go ahead and close the channel (which the bartender can do at any time by just signing and broadcasting the latest transaction: the bartender won't do that because he or she is hoping you'll stay and drink more).
    • If you ended up just hanging around the bar and never ordering, then at closing time + 1 you broadcast the backoff transaction and get your funds back in full.
Now, even if you pass 50 drinks to Jihan Wu, you can't give him the first transaction (the one which pays for only one drink) and ask him to mine it: it's spending a 2-of-2 and the copy you have only contains your own signature. You need the bartender's signature to make it valid, but he or she sure as hell isn't going to cooperate in something that would lose him or her money, so a signature from the bartender validating old state where he or she gets paid less isn't going to happen.
So, problem solved, right? Right? Okay, let's try it. So you get your funds, put them in a funding tx, get the backoff tx, confirm the funding tx...
Once the funding transaction confirms deeply, the bartender laughs uproariously. He or she summons the bouncers, who surround you menacingly.
"I'm refusing service to you," the bartender says.
"Fine," you say. "I was leaving anyway;" You smirk. "I'll get back my money with the backoff transaction, and posting about your poor service on reddit so you get negative karma, so there!"
"Not so fast," the bartender says. His or her voice chills your bones. It looks like your exploitation of the Satoshi nSequence payment channel is still fresh in his or her mind. "Look at the txid of the funding transaction that got confirmed."
"What about it?" you ask nonchalantly, as you flip open your desktop computer and open a reputable blockchain explorer.
What you see shocks you.
"What the --- the txid is different! You--- you changed my signature?? But how? I put the only copy of my private key in a sealed envelope in a cast-iron box inside a safe buried in the Gobi desert protected by a clan of nomads who have dedicated their lives and their childrens' lives to keeping my private key safe in perpetuity!"
"Didn't you know?" the bartender asks. "The components of the signature are just very large numbers. The sign of one of the signature components can be changed, from positive to negative, or negative to positive, and the signature will remain valid. Anyone can do that, even if they don't know the private key. But because Bitcoin includes the signatures in the transaction when it's generating the txid, this little change also changes the txid." He or she chuckles. "They say they'll fix it by separating the signatures from the transaction body. They're saying that these kinds of signature malleability won't affect transaction ids anymore after they do this, but I bet I can get my good friend Jihan Wu to delay this 'SepSig' plan for a good while yet. Friendly guy, this Jihan Wu, it turns out all I had to do was slip him 51 drinks and he was willing to mine a tx with the signature signs flipped." His or her grin widens. "I'm afraid your backoff transaction won't work anymore, since it spends a txid that is not existent and will never be confirmed. So here's the deal. You pay me 99% of the funds in the funding transaction, in exchange for me signing the transaction that spends with the txid that you see onchain. Refuse, and you lose 100% of the funds and every other HODLer, including me, benefits from the reduction in coin supply. Accept, and you get to keep 1%. I lose nothing if you refuse, so I won't care if you do, but consider the difference of getting zilch vs. getting 1% of your funds." His or her eyes glow. "GENUFLECT RIGHT NOW."
Lesson learned?

CLTV-protected Spilman Channels

Using CLTV for the backoff branch.
This variation is simply Spilman channels, but with the backoff transaction replaced with a backoff branch in the SCRIPT you pay to. It only became possible after OP_CHECKLOCKTIMEVERIFY (CLTV) was enabled in 2015.
Now as we saw in the Spilman Channels discussion, transaction malleability means that any pre-signed offchain transaction can easily be invalidated by flipping the sign of the signature of the funding transaction while the funding transaction is not yet confirmed.
This can be avoided by simply putting any special requirements into an explicit branch of the Bitcoin SCRIPT. Now, the backoff branch is supposed to create a maximum lifetime for the payment channel, and prior to the introduction of OP_CHECKLOCKTIMEVERIFY this could only be done by having a pre-signed nLockTime transaction.
With CLTV, however, we can now make the branches explicit in the SCRIPT that the funding transaction pays to.
Instead of paying to a 2-of-2 in order to set up the funding transaction, you pay to a SCRIPT which is basically "2-of-2, OR this singlesig after a specified lock time".
With this, there is no backoff transaction that is pre-signed and which refers to a specific txid. Instead, you can create the backoff transaction later, using whatever txid the funding transaction ends up being confirmed under. Since the funding transaction is immutable once confirmed, it is no longer possible to change the txid afterwards.

Todd Micropayment Networks

The old hub-spoke model (that isn't how LN today actually works).
One of the more direct predecessors of the Lightning Network was the hub-spoke model discussed by Peter Todd. In this model, instead of payers directly having channels to payees, payers and payees connect to a central hub server. This allows any payer to pay any payee, using the same channel for every payee on the hub. Similarly, this allows any payee to receive from any payer, using the same channel.
Remember from the above Spilman example? When you open a channel to the bartender, you have to wait around for the funding tx to confirm. This will take an hour at best. Now consider that you have to make channels for everyone you want to pay to. That's not very scalable.
So the Todd hub-spoke model has a central "clearing house" that transport money from payers to payees. The "Moonbeam" project takes this model. Of course, this reveals to the hub who the payer and payee are, and thus the hub can potentially censor transactions. Generally, though, it was considered that a hub would more efficiently censor by just not maintaining a channel with the payer or payee that it wants to censor (since the money it owned in the channel would just be locked uselessly if the hub won't process payments to/from the censored user).
In any case, the ability of the central hub to monitor payments means that it can surveill the payer and payee, and then sell this private transactional data to third parties. This loss of privacy would be intolerable today.
Peter Todd also proposed that there might be multiple hubs that could transport funds to each other on behalf of their users, providing somewhat better privacy.
Another point of note is that at the time such networks were proposed, only unidirectional (Spilman) channels were available. Thus, while one could be a payer, or payee, you would have to use separate channels for your income versus for your spending. Worse, if you wanted to transfer money from your income channel to your spending channel, you had to close both and reshuffle the money between them, both onchain activities.

Poon-Dryja Lightning Network

Bidirectional two-participant channels.
The Poon-Dryja channel mechanism has two important properties:
Both the original Satoshi and the two Spilman variants are unidirectional: there is a payer and a payee, and if the payee wants to do a refund, or wants to pay for a different service or product the payer is providing, then they can't use the same unidirectional channel.
The Poon-Dryjam mechanism allows channels, however, to be bidirectional instead: you are not a payer or a payee on the channel, you can receive or send at any time as long as both you and the channel counterparty are online.
Further, unlike either of the Spilman variants, there is no time limit for the lifetime of a channel. Instead, you can keep the channel open for as long as you want.
Both properties, together, form a very powerful scaling property that I believe most people have not appreciated. With unidirectional channels, as mentioned before, if you both earn and spend over the same network of payment channels, you would have separate channels for earning and spending. You would then need to perform onchain operations to "reverse" the directions of your channels periodically. Secondly, since Spilman channels have a fixed lifetime, even if you never used either channel, you would have to periodically "refresh" it by closing it and reopening.
With bidirectional, indefinite-lifetime channels, you may instead open some channels when you first begin managing your own money, then close them only after your lawyers have executed your last will and testament on how the money in your channels get divided up to your heirs: that's just two onchain transactions in your entire lifetime. That is the potentially very powerful scaling property that bidirectional, indefinite-lifetime channels allow.
I won't discuss the transaction structure needed for Poon-Dryja bidirectional channels --- it's complicated and you can easily get explanations with cute graphics elsewhere.
There is a weakness of Poon-Dryja that people tend to gloss over (because it was fixed very well by RustyReddit):
Another thing I want to emphasize is that while the Lightning Network paper and many of the earlier presentations developed from the old Peter Todd hub-and-spoke model, the modern Lightning Network takes the logical conclusion of removing a strict separation between "hubs" and "spokes". Any node on the Lightning Network can very well work as a hub for any other node. Thus, while you might operate as "mostly a payer", "mostly a forwarding node", "mostly a payee", you still end up being at least partially a forwarding node ("hub") on the network, at least part of the time. This greatly reduces the problems of privacy inherent in having only a few hub nodes: forwarding nodes cannot get significantly useful data from the payments passing through them, because the distance between the payer and the payee can be so large that it would be likely that the ultimate payer and the ultimate payee could be anyone on the Lightning Network.

Future

After LN, there's also the Decker-Wattenhofer Duplex Micropayment Channels (DMC). This post is long enough as-is, LOL. But for now, it uses a novel "decrementing nSequence channel", using the new relative-timelock semantics of nSequence (not the broken one originally by Satoshi). It actually uses multiple such "decrementing nSequence" constructs, terminating in a pair of Spilman channels, one in both directions (thus "duplex"). Maybe I'll discuss it some other time.
The realization that channel constructions could actually hold more channel constructions inside them (the way the Decker-Wattenhofer puts a pair of Spilman channels inside a series of "decrementing nSequence channels") lead to the further thought behind Burchert-Decker-Wattenhofer channel factories. Basically, you could host multiple two-participant channel constructs inside a larger multiparticipant "channel" construct (i.e. host multiple channels inside a factory).
Further, we have the Decker-Russell-Osuntokun or "eltoo" construction. I'd argue that this is "nSequence done right". I'll write more about this later, because this post is long enough.

CRYPTOCURRENCY CARDANO (ADA)

CRYPTOCURRENCY CARDANO (ADA)

https://preview.redd.it/ajbfzpprwmt31.png?width=1901&format=png&auto=webp&s=6509343a0c882b97a7fe55eeccb873062ba09c66
Cardano is a cryptocurrency running on a decentralized blockchain platform that is under development. The project team strives to gain the trust of users by ensuring transparency of everything that happens in the system.

THE HISTORY OF THE EMERGENCE

Cardano (ADA) was created by a team led by Charles Haskinson, who previously worked on Ethereum, but left the number of cryptocurrency developers before the ICO. In 2014, he and Jeremy wood formed IOHK. In the same year, a group of Japanese investors signed a 6-year contract with this firm to create a blockchain project based on the use of algorithms for independent execution of exchange operations with different types of assets.

https://preview.redd.it/2i65etfaxmt31.png?width=308&format=png&auto=webp&s=29c9fbda1552a59c33452e60afb1bd1b8d6c3d48
The platform was named after Gerolamo Cardano, an Italian mathematician, engineer, philosopher and astrologer. The Ada token was composed of 3 letters of the scientist's surname so that the name of the world's first female programmer-Ada Lovelace - turned out.
The currency ICO was held in several stages in 2015-2017. as a result, $62 million was collected during operations only within the ADA Coin system. Until 2019, the developers plan to launch a number of decentralized applications and services for the implementation of smart contracts.
In the beginning, the team warned that the low speed of operations (only 5-10 transactions per second) can affect the rate of cryptocurrency. Experts plan to increase the speed of transactions by introducing the system of bandwidth nodes, the Protocol of which will be written in the programming language Haskell. Also prevent the success of the project could reputation of the author of the idea of Charles Hoskinson, who left his previous job without explanation. But the cost of the coin was not affected by these factors, the prospects for the project are good.

Cardano Presentation
The success of the project is also facilitated by the fact that it is engaged in 3 institutions performing different functions:

  • IOHK is responsible for the construction of the siege system. This institution is engaged in the technical side of the platform, its improvement.
  • The Cardano Foundation is located in Switzerland. Responsible for the control of the organization and its development, standardization and protection of technologies.
  • Emurgo is based on the Isle of man. The organization was created to promote the company's products in the market.
The goal of the creators of the project is a sustainable system that is able to attract investment and thereby support itself.

MAIN FEATURES OF CARDANO COIN

Cardano (ADA) is a cryptocurrency whose task is to secure smart contracts between users on terms beneficial to both parties. Such principles of asset exchange will be the basis for further development of digital currencies. The Ada token has many pluses, but there are also minuses.

Advantages

  • Democracy in the control of transactions and mining.
  • Scientific approach in the development of the mathematical block of the platform, allowing to have a good traffic generation.
  • High degree of protection against hacker attacks.
  • Anonymity.
  • Protection of users from unscrupulous partners.

Disadvantages

  • Using test software.
  • Incomplete platform management.
  • No protocols for long-term planning.
  • Insufficient control over the data provided by users.

HOW TO MINE CARDANO

The Cardano platform is based on the Proof of Stake algorithm. This means that the chances of a miner to create a block are directly proportional to the assets available to him, the results of work on solving a mathematical problem do not matter.

Advantages of Cardano mining:

  • Easy entry.
  • No expensive equipment is required.
  • Don't need a lot of electricity.
  • Relative stability.

WHERE AND HOW TO BUY CARDANO ADA CRYPTOCURRENCY

Cardano coins are traded in pairs with other cryptocurrencies on most exchanges (Finance, Bitrix, Http, Upbit, Bithumb, Cryptopia, etc.). There are exchangers (Prostocash, Xchange, 60 cek) and Exmo exchange, where you can buy Cardano cryptocurrency for rubles and other Fiat currency, after exchanging it for bitcoins or ethers. You can pay in exchangers via PayPal or Bank card.
Purchase instructions ADA:
  1. To buy in exchange for Bitcoin or Etherium.
  2. Register on the exchange and install a wallet with Cardano support.
  3. Exchange purchased bitcoins or ethers for Cardano.
  4. Withdraw ADA to wallet.

Purchase on Binance
Crypto exchanges provide the ability to store funds, but it is better to withdraw tokens to the wallet immediately after purchase. If this is not possible, you should take care of the security of your account. Asset storage is better not to trust little-known exchanges.

CARDANO WALLET

Until March 2018, the only e-wallet in which ADA could be stored was Daedalus. There are versions for Windows, Mac and Linux. The wallet is suitable for anonymous transactions. The Cardano team plans to issue a debit card that can be replenished through this e-wallet.
Daedalus installation instructions:
  1. Go to the site Cardanohub.org.
  2. Find the Get started tab and go to Deadalus wallet.
  3. Click on Download, download the app.
  4. Open the file, configure the installation settings.

https://preview.redd.it/tyomywqj2nt31.png?width=400&format=png&auto=webp&s=d0cf94f05c85c2205abde505831e5aeaca03dd8e
In March, it became possible to store ADA tokens in the Centra wallet. This means that the currency can be withdrawn using the Centra card in 36 million terminals around the world.

Web wallets are popular because of convenience. Many sites offer to download them to store ADA, but this should not be done, so as not to fall for the tricks of scammers. On the official website of the company there is no data on cooperation with owners of online wallets.

WHAT ARE THE PROSPECTS FOR THE ADA CRYPTOCURRENCY

Given the big plans of Cardano developers, the forecast for 2020 regarding this cryptocurrency is good. If the team implements its ideas to expand the use of coins, ADA may become popular in the market after a while, despite the fall in user confidence in cryptocurrencies.

Road map of Cardano

The author of the platform Hoskinson said that the work on scaling the data will not yield results until 2019. Developers want to introduce innovative technologies into their project, their creation and research takes a lot of time. By the end of the year, it is planned to standardize the protocols and improve the reliability of the system, but the achievement of these goals may be delayed due to the complexity of the ideas. At this stage of operation of the platform, information about the use of high technologies in support of Cardano's work is not proven.
Cryptocurrency faces competition among firms providing such services. It interferes with its development. Specialists working on improving Litecoin and Dash use similar principles when conducting transactions. Ripple plans to become an element combining currencies recognized as official and digital assets, making it more attractive to investors.
The exclusivity of the project is that its development is scientifically justified. But this is not a significant advantage, as most traders do not want to spend time figuring out the details of the technical side of the project, and are interested in its functionality.
If the Cardano project team fulfills its plans by the end of the year, the prospect of this currency is quite good. The success of ADA depends on how convenient the token will be to use.

Decred Journal — June 2018

Note: You can read this on GitHub, Medium or old Reddit to see the 207 links.

Development

The biggest announcement of the month was the new kind of decentralized exchange proposed by @jy-p of Company 0. The Community Discussions section considers the stakeholders' response.
dcrd: Peer management and connectivity improvements. Some work for improved sighash algo. A new optimization that gives 3-4x faster serving of headers, which is great for SPV. This was another step towards multipeer parallel downloads – check this issue for a clear overview of progress and planned work for next months (and some engineering delight). As usual, codebase cleanup, improvements to error handling, test infrastructure and test coverage.
Decrediton: work towards watching only wallets, lots of bugfixes and visual design improvements. Preliminary work to integrate SPV has begun.
Politeia is live on testnet! Useful links: announcement, introduction, command line voting example, example proposal with some votes, mini-guide how to compose a proposal.
Trezor: Decred appeared in the firmware update and on Trezor website, currently for testnet only. Next steps are mainnet support and integration in wallets. For the progress of Decrediton support you can track this meta issue.
dcrdata: Continued work on Insight API support, see this meta issue for progress overview. It is important for integrations due to its popularity. Ongoing work to add charts. A big database change to improve sorting on the Address page was merged and bumped version to 3.0. Work to visualize agenda voting continues.
Ticket splitting: 11-way ticket split from last month has voted (transaction).
Ethereum support in atomicswap is progressing and welcomes more eyeballs.
decred.org: revamped Press page with dozens of added articles, and a shiny new Roadmap page.
decredinfo.com: a new Decred dashboard by lte13. Reddit announcement here.
Dev activity stats for June: 245 active PRs, 184 master commits, 25,973 added and 13,575 deleted lines spread across 8 repositories. Contributions came from 2 to 10 developers per repository. (chart)

Network

Hashrate: growth continues, the month started at 15 and ended at 44 PH/s with some wild 30% swings on the way. The peak was 53.9 PH/s.
F2Pool was the leader varying between 36% and 59% hashrate, followed by coinmine.pl holding between 18% and 29%. In response to concerns about its hashrate share, F2Pool made a statement that they will consider measures like rising the fees to prevent growing to 51%.
Staking: 30-day average ticket price is 94.7 DCR (+3.4). The price was steadily rising from 90.7 to 95.8 peaking at 98.1. Locked DCR grew from 3.68 to 3.81 million DCR, the highest value was 3.83 million corresponding to 47.87% of supply (+0.7% from previous peak).
Nodes: there are 240 public listening and 115 normal nodes per dcred.eu. Version distribution: 57% on v1.2.0 (+12%), 25% on v1.1.2 (-13%), 14% on v1.1.0 (-1%). Note: the reported count of non-listening nodes has dropped significantly due to data reset at decred.eu. It will take some time before the crawler collects more data. On top of that, there is no way to exactly count non-listening nodes. To illustrate, an alternative data source, charts.dcr.farm showed 690 reachable nodes on Jul 1.
Extraordinary event: 247361 and 247362 were two nearly full blocks. Normally blocks are 10-20 KiB, but these blocks were 374 KiB (max is 384 KiB).

ASICs

Update from Obelisk: shipping is expected in first half of July and there is non-zero chance to meet hashrate target.
Another Chinese ASIC spotted on the web: Flying Fish D18 with 340 GH/s at 180 W costing 2,200 CNY (~340 USD). (asicok.comtranslated, also on asicminervalue)
dcrASIC team posted a farewell letter. Despite having an awesome 16 nm chip design, they decided to stop the project citing the saturated mining ecosystem and low profitability for their potential customers.

Integrations

bepool.org is a new mining pool spotted on dcred.eu.
Exchange integrations:
Two OTC trading desks are now shown on decred.org exchanges page.
BitPro payment gateway added Decred and posted on Reddit. Notably, it is fully functional without javascript or cookies and does not ask for name or email, among other features.
Guarda Wallet integrated Decred. Currently only in their web wallet, but more may come in future. Notable feature is "DCR purchase with a bank card". See more details in their post or ask their representative on Reddit. Important: do your best to understand the security model before using any wallet software.

Adoption

Merchants:
BlueYard Capital announced investment in Decred and the intent to be long term supporters and to actively participate in the network's governance. In an overview post they stressed core values of the project:
There are a few other remarkable characteristics that are a testament to the DNA of the team behind Decred: there was no sale of DCR to investors, no venture funding, and no payment to exchanges to be listed – underscoring that the Decred team and contributors are all about doing the right thing for long term (as manifested in their constitution for the project).
The most encouraging thing we can see is both the quality and quantity of high calibre developers flocking to the project, in addition to a vibrant community attaching their identity to the project.
The company will be hosting an event in Berlin, see Events below.
Arbitrade is now mining Decred.

A new kind of DEX was the subject of an extensive discussion in #general, #random, #trading channels as well as Reddit. New channel #thedex was created and attracted more than 100 people.
A frequent and fair question is how the DEX would benefit Decred. @lukebp has put it well:
Projects like these help Decred attract talent. Typically, the people that are the best at what they do aren’t driven solely by money. They want to work on interesting projects that they believe in with other talented individuals. Launching a DEX that has no trading fees, no requirement to buy a 3rd party token (including Decred), and that cuts out all middlemen is a clear demonstration of the ethos that Decred was founded on. It helps us get our name out there and attract the type of people that believe in the same mission that we do. (slack)
Another concern that it will slow down other projects was addressed by @davecgh:
The intent is for an external team to take up the mantle and build it, so it won't have any bearing on the current c0 roadmap. The important thing to keep in mind is that the goal of Decred is to have a bunch of independent teams on working on different things. (slack)
A chat about Decred fork resistance started on Twitter and continued in #trading. Community members continue to discuss the finer points of Decred's hybrid system, bringing new users up to speed and answering their questions. The key takeaway from this chat is that the Decred chain is impossible to advance without votes, and to get around that the forker needs to change the protocol in a way that would make it clearly not Decred.
"Against community governance" article was discussed on Reddit and #governance.
"The Downside of Democracy (and What it Means for Blockchain Governance)" was another article arguing against on-chain governance, discussed here.
Reddit recap: mining rig shops discussion; how centralized is Politeia; controversial debate on photos of models that yielded useful discussion on our marketing approach; analysis of a drop in number of transactions; concerns regarding project bus factor, removing central authorities, advertising and full node count – received detailed responses; an argument by insette for maximizing aggregate tx fees; coordinating network upgrades; a new "Why Decred?" thread; a question about quantum resistance with a detailed answer and a recap of current status of quantum resistant algorithms.
Chats recap: Programmatic Proof-of-Work (ProgPoW) discussion; possible hashrate of Blake-256 miners is at least ~30% higher than SHA-256d; how Decred is not vulnerable to SPV leaf/node attack.

Markets

DCR opened the month at ~$93, reached monthly high of $110, gradually dropped to the low of $58 and closed at $67. In BTC terms it was 0.0125 -> 0.0150 -> 0.0098 -> 0.0105. The downturn coincided with a global decline across the whole crypto market.
In the middle of the month Decred was noticed to be #1 in onchainfx "% down from ATH" chart and on this chart by @CoinzTrader. Towards the end of the month it dropped to #3.

Relevant External

Obelisk announced Launchpad service. The idea is to work with coin developers to design a custom, ASIC-friendly PoW algorithm together with a first batch of ASICs and distribute them among the community.
Equihash-based ZenCash was hit by a double spend attack that led to a loss of $450,000 by the exchange which was targeted.
Almost one year after collecting funds, Tezos announced a surprise identification procedure to claim tokens (non-javascript version).
A hacker broke into Syscoin's GitHub account and implanted malware stealing passwords and private keys into Windows binaries. This is a painful reminder for everybody to verify binaries after download.
Circle announced new asset listing framework for Poloniex. Relevant to recent discussions of exchange listing bribery:
Please note: we will not accept any kind of payment to list an asset.
Bithumb got hacked with a $30 m loss.
Zcash organized Zcon0, an event in Canada that focused on privacy tech and governance. An interesting insight from Keynote Panel on governance: "There is no such thing as on-chain governance".
Microsoft acquired GitHub. There was some debate about whether it is a reason to look into alternative solutions like GitLab right now. It is always a good idea to have a local copy of Decred source code, just in case.
Status update from @sumiflow on correcting DCR supply on various sites:
To begin with, none of the below sites were showing the correct supply or market cap for Decred but we've made some progress. coingecko.com, coinlib.io, cryptocompare.com, livecoinwatch.com, worldcoinindex.com - corrected! cryptoindex.co, onchainfx.com - awaiting fix coinmarketcap.com - refused to fix because devs have coins too? (slack)

About This Issue

This is the third issue of Decred Journal after April and May.
Most information from third parties is relayed directly from source after a minimal sanity check. The authors of Decred Journal have no ability to verify all claims. Please beware of scams and do your own research.
The new public Matrix logs look promising and we hope to transition from Slack links to Matrix links. In the meantime, the way to read Slack links is explained in the previous issue.
As usual, any feedback is appreciated: please comment on Reddit, GitHub or #writers_room. Contributions are welcome too, anything from initial collection to final review to translations.
Credits (Slack names, alphabetical order): bee and Richard-Red. Special thanks to @Haon for bringing May 2018 issue to medium.

5 most promising Altcoins for long-term investments | Coinscapture

5 most promising Altcoins for long-term investments | Coinscapture

After the success of Bitcoin and the rise in the price of the first-ever cryptocurrency, many new coins were developed in cryptoworld. In simple words, any coin other than bitcoin is termed as “Altcoins”. These coins are created by tweaking the Bitcoin's or any other existing cryptocurrencies protocol. In the growing world of cryptocurrency, there are more than 3000 cryptocurrencies which came into existence and so it is a tough job to choose the right Altcoin to invest in it. Here are the 5 most promising Altcoins that can help you to narrow your search.
Disclaimer: This guide should not be considered as financial advice. It is highly recommended to do appropriate market research before any investments.

Litecoin

After the successful launch of Bitcoin, Litecoin was the next one to enter the Cryptoworld in 2011. Charlie Lee - a computer scientist created Litecoin by making some technical changes in the bitcoin’s source-code and made it the fastest peer-to-peer currency that enabled instant, near-zero cost payments to anyone across the world. Also, litecoin has a total supply of 84 million with an average block mining time of 2.5 minutes.

Reasons why to choose Litecoin as a Long-Term Investment

  • Improved: Litecoin algorithm is generally easier to mine but difficult to crack The bitcoin mining is highly processed intensive requiring, application-specific integrated circuit devices with high processing capabilities, while Litecoin mining is memory-intensive requiring less cost-intensive graphics processing units (GPU).
  • Faster block-processing rate: The technical changes done on Bitcoin’s source-code allows Litecoin to processes a block at a much faster rate and giving out rewards to the miner faster in every 2.5 minutes as compared to Bitcoin which processes a block in every 10 minutes. Litecoin network have more capacity to handle the transactions than bitcoin's network
  • SegWit upgrade: Litecoin's SegWit upgrade boost the capacity of the number of transactions a block can hold in litecoin's blockchain, thereby speeding up the transaction settlement times and lowering transaction costs.
  • Higher trading volume: The trading of Litecoin has begun since 2011 and since then it was in the top 10 list of coins. The popularity of Litecoins is so much that you won't face any problem selling them in the future which brings less fear of having risk as compared to other new coins.

Ethereum

Ethereum is the second-largest digital currency introduces Vitalik Buterin in late 2015. It has been a popular choice in many industries as its cool feature named Smart Contracts helps developers to build decentralized applications (dApps) on top of its (i.e. Ethereum's) blockchain which helps to avoid fraud, downtime, and control or interference from a third party. Ethereum can also be used for banking and financial service contracts, ICOS, prediction markets, replacing escrow, identity management. The Enterprise Ethereum Alliance founded in 2017 has over 200 organizations that are testing on various versions of Ethereum's blockchain in different industries. Ethereum has a circulating supply of 106,376,346 ETH, the market capitalization of $26,307, 580,992 and faster transaction of 6 minutes as compared to Bitcoin.

Reasons why to choose Ethereum as a Long-Term Investment

  • Multi-purpose usage- Other than trading Ethereum can be used for ICOs, prediction markets, building tokens and many more ways that very few cryptocurrencies can do as good as Ethereum.
  • Safety: The apps built on Ethereum’s blockchain termed as dApps or decentralized apps are significantly safer and more resistant to hacking than the software you use now.
  • Smart contracts: The smart contract feature offers significant business benefits over more traditional conventional forms of cloud computing and transaction-clearing.
  • Initial Coin Offerings: Ethereum is used ICOs (Initial Coin Offerings) that means it acts as a launchpad for new tokens which thereby makes it a valuable platform and price will increase with its use.

Ripple

Ripple is the hot choice in banking and financial institutions as it can be used as an intermediary for quick transaction-processing and settlement service; allowing to transact directly and instantly across national borders. XRP currently has a fast transaction processing time of about 4 seconds and a cheap transaction fee about $0.004 per transaction (which is less than half a cent). It has a circulating supply of 42,181,995,112 and a market capitalization of around 17 billion USD.

Reasons why to choose Ripple as a Long-Term Investment

  • Well distributed: Ripple is an open-source technology, built on the principles of blockchain with an increasing set of validators.
  • Highly Scalable: XRP has the potential to handle 1,500 transactions per second, 24x7, and can scale to deal with a similar throughput as Visa.
  • Highly Stable: The most stable record of Ripple makes it ready for institutional and enterprise use.
  • Global Bank partners: Ripple has partnered with over 100 banks like Bank of America, UBS, Standard Chartered, Barclays, JP Morgan, Santander, and American Express.

Stellar

Stellar offers the fastest and the cheapest online payment and cross-border payment services as compared to the other large companies. Also, it does not use proof of work verification which is time and energy consuming which allows processing a transaction in approx 5 seconds. It has a market capitalization of $2,378,213,121 and a circulating supply of 19.331,689,641.

Reasons why to choose Stellar as a Long-Term Investment

  • Low-cost transactions: Stellar’s payment protocol prioritizes profit, the low transaction time and high operational efficiency translates to a lower cost of transactions.
  • Currency exchanger: Stellar’s platform also acts as a currency exchanger between government-backed currencies, such as dollars to euros.
  • Creating tokens: Launching a token on the Stellar platform is super easy because of the simple programming.
  • Tech elements: Stellar can integrate with elements such as blockchain smart contracts, and multi signatures that enhances the functionality of the payment protocol

Binance Coin

Binance coin is the official coin of the Binance platform that offers a stage for trading cryptocurrencies. Binance is soon launching its own decentralized exchange, Binance DEX that would be available on all platforms, such as Windows, Linux, Mac OS, iOS and Android. BNB has a market capitalization of 4 billion USD and a circulating supply of 141,175,490.

Reasons why to choose Binance Coin a Long-Term Investment

StrataMiner is ready for download. Feature-packed software package for controlling and monitoring any number of rigs.

StrataMiner is now released for beta testing. Looking for a few brave miners.
Go to strataminer.com to learn and install.
I'll be answering any questions here today. For technical support, please email me at [email protected]. Tell me what operating system you're on in the email message.
Features
Windows and Linux - Made for both. Client and Control Center don't need to be on the same OS either.
Profit Switching - Flip the switch and you'll always be mining the best currency for each device.
Any pool - StrataMiner works with any pool using a standard stratum protocol.
Web Portal - Control your rigs from anywhere on the planet with an internet connection.
24 coins and counting - AEON, Bitcoin Gold, Denarius, Ethereum, Ethereum Classic, GoByte, Groestlcoin, HUSH, Komodo, LOKI, Monacoin, Monero, MusicCoin, Pirl, Quantum Resistant Ledger, Ravencoin, Trezarcoin, Ubiq, Verge, Vertcoin, Vivo, ZCash, ZClassic, Zen. More coming.
Exchange address generation - StrataMiner can generate deposit addresses on your Cryptopia and Bittrex accounts. Once your crypto hits your exchange, you can easily exchange for 100s of others. More exchanges coming soon.
One-click updates - No installers required for updates of mining core software. Stay up-to-date through Control Center with a single click.
Community features - With pool sharing enabled, you become part of a community working to ensure pools are always available and trustworthy. This service is part of StrataMiner's commitment to decentralized mining.
Hashrate verification - StrataMiner's proprietary Adaptive Proxy technology enables auditing of pool communications to verify that hashrate reports match share submission statistics. In other words, StrataMiner makes sure everybody is being honest.
Familiar miner cores - Ethminer, Claymore Miner, CCMiner, EWBF, XMR-Stak
Automatic network configuration - The Control Center and Client know how to find each other. Turn them on and go.
Email notifications - Requires Gmail. Receive an email if something's not right. The messaging is still a little rudimentary.
Low fees - 0.5% for development. Miner cores and pools may have additional fees.
Earnings tracking - Earnings estimations are tracked over time. Earnings are recorded in both USD and crypto.
Market data - Up to date market information for each currency, including market capitalization, price, and 24-hour change.
Open source software - The Control Center is open-source and written in Python 3. See pystrata on github if you're interested in fiddling with the code.
What you get for your fee
New miners and algorithms - New stable miners will be incorporated based on community desire. Strataminer tracks algorithm changes and blockchain forks for you, so you'll always have working software, if available.
New coins - Many can be added within hours of receiving a request. No software updates required.
New features - The feature set will be improved based on community feedback. This is only the beginning.
Technical support - Development fees enable StrataMiner to respond to issues and fix bugs quickly and continuously.
StrataMiner API - New coin data, new mining software, and some market data come from the StrataMiner API.
An obvious drawback is that you'll need an address for each currency that you want to mine. If you have Cryptopia and Bittrex accounts, you can use auto-generation to make addresses for all but 4 of the supported currencies (XMR, AEON, LOKI, QRL). I'll work on integrating Binance, CoinExchange, and HitBTC next.
The Coinomi mobile wallet can also get you 16 of the 24 supported currencies.
You'll need pretty fresh drivers, partly for StrataMiner and partly for the miner cores, i.e. Ethminer, ... I actually expect to ease up on StrataMiner's driver requirements a little, but you'll still want to keep fresh drivers for the mining software updates, as they come.
On request, I've lowered the driver requirements for StrataMiner itself, but if you don't have the newest drivers, you may not be able to use Ethminer. You can still use Claymore for Ethash though. Minimum drivers are now >= 385.54 on Windows, >= 384.81 on Linux.
StrataMiner is not affiliated with or sponsored by any exchange, any pool, any other website, or any other software vendor.

Groestlcoin Release September 2018

Introduction

As always, the past 3 months since 22nd June have been crazy busy. The bears might still be around, but the show must go on and of course has not slowed the Groestlcoin development team in the slightest. Here’s a quick overview of what has already happened since the last release: - Integrated into the bitbns exchange, with the ability to buy Groestlcoin directly with the Indian Rupee. - Groestlcoin Rebrand Vote – Whilst there was much talk and push for a rebrand vote, the overall result was almost unanimously in favour of keeping our unique and conversation-starting name. With just 83 votes to Rebrand, and 2577 votes to No Rebrand. Thank you for all who voted, the funds raised are being used to fund ongoing hosting and development costs. - Integrated into the Cryptobridge exchange. Cryptobridge is a popular decentralised exchange where you always hold the private keys to your funds, only YOU have access to them. - Groestlcoin has been added to SimpleSwap – Groestlcoin can now be swapped with over 100 other cryptocurrencies, without signing up! - Groestlcoin has been added to UnoDax, one of the leading cryptocurrency exchanges in India, with TUSD, BTC and INR trading pairs. - Groestlcoin has been added to SwapLab.cc, where you can buy Groestlcoin using Bitcoin and over 50 other altcoins. Purchasing with VISA/Mastercard is coming VERY SOON. Discussed later: - Groestlcoin has been listed on #3 largest exchange in the world on volume, Huobi Global! More on this to come further on in the announcements. - Groestlcoin has been added to the Guarda Multi-Currency Wallet. - Groestlcoin has been added to Melis Multi-Device, Multi-Account, Multi-Platform, Multi-Signature advanced wallet! Already this list is far more than most other cryptocurrencies have achieved in the past 3 months. But this is just the tip of the iceberg of what has been developed.

What's been Happening?

GRSPay Released

We are so excited for this, that it has it's own separate reddit thread. Head over there now at https://www.reddit.com/groestlcoin/comments/9ikr5m/groestlcoin_releases_grspay/? to see more on this!
https://www.melis.io/assets/logo-navbar-4b6f0d372f15b2446d3fa4c68f346e4fb08ee113941186cee58fd6135f3f8b7d.svg

Melis Wallet

The the most advanced wallet for Bitcoin, Bitcoin Cash, Litecoin and now Groestlcoin.
With Melis you have the complete control of your bitcoins and private keys, you can define spending limits policies and make use of two or more factors authentication. Melis is open source, published on GitHub.

How Melis Works?

You can create as many accounts as you want. An account is a part of your wallet that can be customised to your requirements. You can choose how many co-signers are required to spend funds. The accounts are completely independent and act like separate wallets from each other but can be accessed via the same details. A core feature of Melis is the ability to set a ‘primary’ device. With this you can set an account as ‘Secure’ so it is only viewable (and accessible at all) from the Primary device. You can have a savings account hidden from the outside world whilst also having your ‘spending’ funds available on the go. With Melis you can create a multi-signature account between N people, where up to N signatures are required to sign a transaction, choosing if any of those should be mandatory.

Integrated into Blockchain Financial

What is Blockchain Financial?

Blockchain Financial is a set of web based services for individuals and companies that want to make things happen with the Cryptocurrencies Ecosystem. - For those that don't know anything about cryptocurrencies, we offer tools that will let them receive, send and operate with an assortment of coins. - For those that are already riding the wave, we offer tools that will let them do all those things that they weren't able to do.

Blockchain Financials mission

We're not here to reinvent the wheel. We're here to make it run smoother for you, and we provide some of the most useful services you'll find on the internet, made in a way that is easy to understand and use on a daily basis. In short, we're a bunch of people that claim to be Crypto Evangelists. We strongly believe in cryptocurrencies, and our main promise is to push them up so more people get involved and take all the advantages they offer.

More information from Blockchain Financial

Back in 2014, the world was taken by storm when Facebook approved the first cryptocurrencies tipping apps. The first was for Dogecoin, and the second was for multiple coins.
The project was hosted on whitepuma.net, and persisted for almost two years, built up a massive user community and gave a home to Bitcoin, Litecoin, Dogecoin and dozens of other bitcoin-based altcoins.
After very active months, the tipping hype started to fade away. Then, the developers decided to jump into the next stage: bringing not only tipping, but also mining and a widget that could be embedded on websites to allow everyone to accept payments. Sadly, the work was never completed because the project started to require an unsustainable amount of resources. Then, in a painful decision, a shutdown was announced by December 2015.
A couple of months after whitepuma.net was closed, the source code was released by its creator as Open Source on GitHub. But it wasn't maintained.
Now, some of the original members of the dev and admin teams gathered up with a handful of the WhitePuma's elite users, and decided to make something good with the best pieces of the old source code. That, with fresh new ideas and the power of the BardCanvas engine, synthesized the core of Blockchain Financial.

Groestlcoin Core v2.16.3 - Please Update ASAP

A new major Groestlcoin Core version 2.16.3 is now available for download which includes both a Denial of Service component and a critical inflation vulnerability, so it is recommended to upgrade to it if you are running a full Groestlcoin node or a local Groestlcoin Core wallet.
v2.16.3 is now the official release version of Groestlcoin Core. This is a new major version release with a very important security updates. It is recommended to upgrade to this version as soon as possible. Please stop running versions of Groestlcoin Core affected by CVE-2018-17144 ASAP: These are 2.13.3 and 2.16.0.
As a result in this, all exchanges and services have been asked to upgrade to this version, so please be patient if wallets go in to maintenance mode on these services.

What's new in version v2.16.3?

This is a major release of Groestlcoin Core fixing a Denial of Service component and a critical inflation vulnerability (https://nvd.nist.gov/vuln/detail/CVE-2018-17144) exploitable by miners that has been discovered in Groestlcoin Core version 2.13.3 and 2.16.0. It is recommended to upgrade to 2.16.3 as soon as possible. If you only occasionally run Groestlcoin Core, then it's not necessary to run out and upgrade it right this second. However, you should upgrade it before you next run it. If you know anyone who is running an older version, tell them to upgrade it ASAP. Stored funds are not at risk, and never were at risk. At this time we believe over half of the Groestlcoin hashrate has upgraded to patched nodes. We are unaware of any attempts to exploit this vulnerability. However, it still remains critical that affected users upgrade and apply the latest patches to ensure no possibility of large reorganizations, mining of invalid blocks, or acceptance of invalid transactions occurs.

The Technicals

In Groestlcoin Core 2.13.3, an optimization was added (Bitcoin Core PR #9049) which avoided a costly check during initial pre-relay block validation that multiple inputs within a single transaction did not spend the same input twice which was added in 2012 (Bitcoin Core PR #443). While the UTXO-updating logic has sufficient knowledge to check that such a condition is not violated in 2.13.3 it only did so in a sanity check assertion and not with full error handling (it did, however, fully handle this case twice in prior to 2.1.0.6). Thus, in Groestlcoin Core 2.13.3, any attempts to double-spend a transaction output within a single transaction inside of a block will result in an assertion failure and a crash, as was originally reported. In Groestlcoin Core 2.16.0, as a part of a larger redesign to simplify unspent transaction output tracking and correct a resource exhaustion attack the assertion was changed subtly. Instead of asserting that the output being marked spent was previously unspent, it only asserts that it exists. Thus, in Groestlcoin Core 2.16.0, any attempts to double-spend a transaction output within a single transaction inside of a block where the output being spent was created in the same block, the same assertion failure will occur. However, if the output being double-spent was created in a previous block, an entry will still remain in the CCoin map with the DIRTY flag set and having been marked as spent, resulting in no such assertion. This could allow a miner to inflate the supply of Groestlcoin as they would be then able to claim the value being spent twice.
Groestlcoin would like to publicly thank Reddit user u/Awemany for finding CVE-2018-17144 and reporting it (https://lists.linuxfoundation.org/pipermail/bitcoin-core-dev/2018-Septembe000064.html). You deserve gratitude and appreciation from cryptoworld, and you have ours.

Groestlcoin EasyVanity Released

Groestlcoin EasyVanity is a Windows app is built from the ground-up in C# and makes it easier than ever before to create your very own bespoke Groestlcoin address(es), even whilst not connected to the internet! You can even generate multiple keys with the same prefix and leave it on overnight whilst your CPU or GPU collects and stores these addresses locally.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then Groestlcoin EasyVanity is the right choice for you to create a more personalized address.

Features

• Ability to continue finding keys after first one is found • Includes warning on startup if connected to the internet • Ability to output keys to a text file (And shows button to open that directory) • Ability to make your match case sensitive (Where possible) • Show and hide the private key with a simple toggle switch, and copy the private key straight to your clipboard • Show full output of commands • Includes statistics whilst the application is running • Ability to choose between Processor (CPU) and Graphics Card (GPU) • Automatically detects 32 or 64 bit systems • Features both a Light and Dark Material Design inspired Themes • EasyVanity's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky. • EasyVanity includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. • Prefixes are exact strings that must appear at the beginning of the address. When searching for prefixes, Easyvanity will ensure that the prefix is possible, and will provide a difficulty estimate. • The percentage displayed just shows how probable it is that a match would be found in the session so far. If it finds your address with 5% on the display, you are extremely lucky. If it finds your address with 92% on the display, you are unlucky. If you stop EasyVanity with 90% on the display, restart it, and it finds your address with 2% on the display, your first session was unlucky, but your second session was lucky. • EasyVanity uses the OpenSSL random number generator. This is the same RNG used by groestlcoin and a good number of HTTPS servers. It is regarded as well-scrutinized. Guessing the private key of an address found by EasyVanity will be no easier than guessing a private key created by groestlcoin itself. • To speed up address generation, EasyVanity uses the RNG to choose a private key, and literally increments the private key in a loop searching for a match. As long as the starting point is not disclosed, if a match is found, the private key will not be any easier to guess than if every private key tested were taken from the RNG. EasyVanity will also reload the private key from the RNG after 10,000,000 unsuccessful searches (100M for oclvanitygen), or when a match is found and multiple patterns are being searched for. • Free software - MIT. Anyone can audit the code. • Written in C# - The code is short, and easy to review.

What is Finatch?

ABOUT FINATCH Finatch is a private Blockchain Technology Company which aim's at revolutrionizing the Blockchain Technology industry.
Looking at the lack of stable, fast and reliable decentralized crypto exchanges which causes inconviniences to crypto traders in the space. We have come up with the solution to the problems faced by decentralized exchanges.
There are basically two different types of exchanges: Centralized and Decentralized exchanges. We will focus on the Deentralized exchange system. We have a strong belief that Decentralized based crypto exchanges will be bigger than Centralized based crypto exchanges in the nearest future, because Blockchain is all about Decentralization.
They will play an evermore role in the world of finance, and we call this FINATCH EXCHANGE. FINATCH EXCHANGE Finatch Exchange is a Decntralized crypto exchange, which is run and powered by the Finatch Smart Contract Blockchain. Problems Poor technical architecture in Decentralized exchanges There are a good number of exchanges set up by professionals who have little or no experience in finance or in operating an exchange. They often take the easiest route to get the system up and running. While this may work well in the beginning, as traffic grows, the system will not be able to handle the increased load. Exchange systems need to be engineered from the ground up with security, efficiency, speed, and scalability in mind. This often slows down the initial development, but is critical for long-term success.
Our team has decades of combined experience building and maintaining world class financial systems that shape the economy. We understand how these systems are built from the ground up. Slow Smart Contract confirmation time Deployment of Smart contract on the blockchain takes time and causes inconveniences becauses of the poorly built blockchain, this results in a bad user experience in decentralized crypto exchanges.
Our team has designed a new and capable type of Blockchain that speeds up confirmation time for smart contratcts, making the platform user friendly and smooth. Insecured Platform There are hundreds of exchanges that went down due to being hacked.
Finatch is built to top notch quality, audited, and penetration tested. We have experience building financial systems to the highest security standards and strive to ensure security first. Poor market liquidity Professional traders and normal users are significantly affected by this. Having a shallow orderbook means high slippage when trading, which is very expensive for traders.
Finatch’s team have been in both the finance and crypto industry for many years. The team has worked on and operated a number of exchanges, and have accumulated a large network of partners in this space. These partners will be key in bootstrapping the exchange. Poor customer service Traders are a different breed when it comes to users. Understanding the trader mentality is vital for running a successful exchange. Money is literally on-the-line. Many exchange service trades as if they were running a social media site. A 3-second delay in seeing your friends’ status update would hardly be noticed, but on an exchange, the same would be unacceptable, resulting in a torrent of user complaints.
In additional to the technology stack, Finatch is built with service in mind. Finatch shares and supports responsibilities across the entire staff and company. When a trader has a problem, they get an answer directly from someone who knows the system and not someone reading from a script. Limited access to decentralized services There are few existing decentralized exchanges with close to good user interface and lacks quick and reasonable smart contract transaction fees, causing slow platorm functioning.
Our team has designed a new and capable type of Blockchain that speeds up confirmation time for smart contratcts, making the platform user friendly and smooth. Poor internationalization and language support Blockchains have no borders. Most exchanges focus only on one language or one country.
Our international multi-lingual team has extensive working experience in North America, Europe, Asia and Africa and we are able to smoothly support the global market. Lack of transparency All trading activities should be decentralized and open to the general public to insure trust and transparency in trades. Centralized crypto exchanges lack this quality.
Finatch runs on a Decentralized crypto platform where all trading activities are transparent.
Finatch is a Crypto Decentralized crypto exchange that has the feel and look of Centralized Crypto exchange but with more convinience And extra Blockchain Security Layer. An Exchange where you own your private keys.
Finatch exchange is a huge decentralized trading exchange platform equipped with various sub-platform, trading tools and secure decentralized wallet.
Finatch exchange consists of various sub platforms to choose from, this changes the trading experience namely: 1. Binary Platform: Fin vault platform, FinBox platform 2. Finatch trading tools: Finatch exchange have the best trading tools ready for traders on all our trading platform, taking trading experience to the next level. You can choose from our multiple trading tools the one that suits your trading skills. 3.Andriod and iOs Mobile Trading Application. MATCHING ENGINE With our Unique Smart Contract Blockchain Our matching engine is capable of sustaining 1,500,000 orders / second, making Finatch one of the fastest exchanges in the market today. You can be certain, on our exchange, that your orders will never be stuck due to the matching engine being overwhelmed.
FEATURE ROLLOUT We will roll out the platform in roughly the following order: Decentralized (on-chain) exchange Spot trading Margin trading Futures Anonymous instant exchange and more... COINS Finatch will support trading pairs in the following coins: BTC ETH LTC BCH FIN (Finatch Coin) More coins will be added over time. We generally will only add coins that have strong credibility, user base, and liquidity. If you have a coin that you wish to be listed on Finatch later. DEVICE COVRAGE We will provide cross-platform trading clients for: Web-based decentralized trading client Android native client iOS native client (pending App Store review) Mobile HTML5 client (including WeChat H5 client) PC (Windows) native client REST API MULTILINGUAL SUPPORT We will support English, Chinese, Japanese and Korean on all of our user interfaces. (The very initial release will be in English only.) More languages will be added over time.
FINATCH COIN We will build our own Blockchain based Crypto coin, called the Finatch Coin. The Finatch Coin Total Supply is capped at 952.5M, but a strict pre mine of 200M FIN will be mined during the genesis Block. FIN Coin will run on the Finatch Blockchain. Percentage (%) Amount (FIN) Participant 25% 50,000,000 Airdrop&Bounty Programs 25% 50,000,000 Project Development 40% 80,000,000 Founding Team 10% 20,000,000 Angel Investors No ICO or Pre-ICO will take place. 50% of pre-mined Coins will be distributed to the general Public Via Airdrop stages and Bounty Programs. FIN VALUE AND REPURCHASING PLAN You can use FIN to pay for any fees on our platform, inculding but not limited to: Exchange fees Withdraw fees Listing fees Any other fee
When you use FIN to pay for fees, you will receive a significant discount: 1st year 2nd year 3rd year 4th year 5th year Discount Rate 60% 30% 12.5% 6.75%5 no discount
REPURCHASING PLAN Every quater, we will use 15% of our profits to buy back the pre-mined FIN coin and Burn them, until we buy up 50% of the pre-mined FIN coin during genesis block (100M) back. All buy back transactions will be annouced on the blockchain. FUNDS USAGE
35% of the funds will be used to build the Finatch platform and perform upgrades to the system, which inculdes team recruiting, training, and the development budget. 50% will be used for Finatch branding and marketing, including continuous promotion and education of Finatch and Blockchain innovations in industry mediums. A sufficient budget for various advertisment activities, to help Finatch become popular among investors, and to attract active users to the platform. 15% will be kept in reserve to cope with any emergency or unexpected situation that might come up. FINATCH BLOCKCHAIN Finatch Blockchain is a powerful unique blockchain built to solve the problems of long confirmation times and high transaction fees on smart contract Blockchains.
We also solve the scalablity problem with block size, by increasing the block size limit to 1GB. Finatch Blockchain can handle more than 100,000,000 tranactions per second, with as little to as low as $0.001 tranaction fee, making our blockchain the most convinent and reliable blockchain in exixtence.
Our Blockchain runs on Scrypt PoW/PoS and Fault Tolorence Algorithms, making it one the most secure blockchains. You can deploy smart contracts, decentralized applications and create your own (FRC Tokens) on our blockchain.
BUILD DECENTRALIZED APPLICATIONS Combining a modified Bitcoin Core infrastructure with an intercompatible version of the Ethereum Virtual Machine (EVM), Finatch Blockchain merges the reliability of Bitcoin’s unfailing blockchain with the endless possibilities provided by smart contracts.
Designed with stability, modularity and interoperability in mind, Finatch Blockchain is the foremost toolkit for building trusted decentralized applications, suited for real-world, business oriented use cases. Its hybrid nature, in combination with a PoS/PoW consensus protocol, allows Finatch Blockchain applications to be compatible with major blockchain ecosystems, while providing native support for mobile devices and IoT appliances.
DEPLOY DECENTRALIZED SMART CONTRACTS Finatch makes it easier than ever for established sectors and legacy institutions to interface with blockchain technology. Create your own tokens, automate supply chain management and engage in self-executing agreements in a standardized environment, verified and tested for stability.
SMART CONTRACT LIFE CYCLE MANAGMENT Finatch, in cooperation with its academic partners, develops tools and methods to standardize the workflow for business smart contract development. This includes the formally verifiable translation of human-readable agreements to machine smart contracts, and the error-resilient specification of their elements, terms and conditions.
SETTING INDUSTRY STANDARDS Cooperating with a series of partners and third parties, Finatch aims to establish a smart contract hub, offering secure and thoroughly tested contract templates, tailor fitted for a multitude of industries and use cases, such as supply chain management, telecommunications, IoT, social networking, Crypto exchanges and many more. ABOUT FIN COIN FIN Coin is a decentralised Cryptocurrency based on Finatch. It is the local based Cryptocurrency of Finatch Blockchain. FIN Coins are cryptographic software tokens used to engage with distributed applications (DApps) and smart contracts on the Finatch Platform. FIN Coins will serve as the staking currency of the Finatch blockchain and fuel computational operations performed by the Finatch network.
SPECIFICATION Total Pre-Mined Supply: 200,000,000 Block Target: 3-15 seconds Stake Return: ~5 FIN Coin Algorithm: Scrypt PoW/PoS and FT The FINATCH Foundation: Governance Structure The development and maintenance of the FINATCH Blockchain, as well as all services provided by FINATCH, are directed and supervised by the FINATCH Foundation - a non-profit organization, representing FINATCH’s stake and token holders as elaborated below.
In order to avoid the inefficient conduct, open source and blockchain projects often suffer from, and to ensure a coherent and standardized implementation of the FINATCH blockchain, the FINATCH Foundation was established under the guidance and support of FINATCH Inc. The Foundation will oversee the development of the FINATCH Blockchain, advocate governance transparency, and promote the safety and harmony of the open source ecosystem.
The design of the Foundation’s governance structure mainly considers sustainability, management effectiveness, and fund-raising security in the open source community. The Foundation consists of various committees, such as Executive Judgment, Code Review, Finance & HR, as well as Marketing & PR. The different committees work in cooperation to manage FINATCH’s daily operations and special occasions with detailed operational procedures and rules.
Learn more here: https://finatch.org/governance-structure
Decentralized Governance Protocol The Decentralized Governance Protocol (DGP) is designed so that individual blockchain parameters can be modified through a specially designed smart contract on the blockchain. Most importantly, this technology allows these blockchain parameters to be changed without any disruption to the ecosystem. After a setting change, no new software must be downloaded by users, and no intervention is needed from stakers, miners and node operators.
The way the DGP works is relatively straightforward. First, a governing party for the DGP makes a proposal to change a parameter. Afterward, all the governing parties for the DGP can vote on the proposal, and if it receives enough approval votes, then the parameter change proposal becomes active. The proposal data is then placed in a standardized format and a particular storage space so that the blockchain software can easily access it without needing to execute the DGP contract directly.
Learn more here: https://finatch.org/decentralized-governance-protocol
The FINATCH Foundation will list the total assets that it holds including Bitcoin, Ethereum, Legal Tender, and FIN COINS. The Foundation will also seek complementary services to aid our efforts in transparency and professionalism with a professional auditing firm, legal team and a professional digital asset management solution. We hope this will help promote the healthy development of the FINATCH Project and serve as a model for other projects. The content will be made public to the community on the FINATCH.org Website

Transaction costs are fractions of a penny and our blockchain and open ledger players can be confidant their deposited funds are safe and used only to pay out prize pools.
Unlike using traditional centralized payment processing the Fantasy Gold project does not charge any addition transaction or service fees to use the payment network. Senders pay a small transaction fee that is awarded to miners who process the transactions and Masternodes who verify the transactions. Anyone with access to standard desktop graphics cards can act as a miner and anyone who holds 10,000 Fantasy Gold coins can run a Masternode on a basic VPS server or even a Raspberry Pi.
Fantasy Sports Fantasy Gold will host daily fantasy sports contests on its own branded site DraftDaily.com using the Company’s proprietary Daily Fantasy Sports (“DFS”) platform. DraftDaily.com allows users compete against one another to win prizes awarded in Fantasy Gold Coin (FGC). The site currently offers daily and weekly fantasy sports contests for the following sports leagues: NFL, MLB, NBA and NHL. We anticipate lunching Fantasy Cricket in May 2018 followed by Fantasy Soccer.
Esports eSports tournaments and 1v1 contests will be hosted on the Company’s proprietary eSports platform, FGCArena.com. Fantasy Gold will hold monthly live tournament events starting in May 2018 in Las Vegas with a minimum of 300,000 expected viewers per event. Fantasy Gold Coin will be the in game currency used for tournament entries and prize pools. Live events may also include additional cash prizes provided by sponsors and from crowd sourcing. FantasyGold has partnered with Millennial eSports to organize the events to be held at their eSports Arena in Las Vegas.
FantasyGold Masternodes Masternodes help secure the Fantasy Gold network by making it more decentralized, providing a consensus for every transaction.
Masternodes are nodes (servers) that run the Fantasy Gold wallet software that provide additional services to the network including instant and private transactions. However the one of the more important features are decentralized community governance and budgeting systems and the ability to publish immutable proposals to the community with the means to vote on proposals. For providing these important services, Masternode owners are rewarded a portion of each block.
Block Rewards will be split between POS and Masternodes as follows: 20% POS / 80% Masternodes The block reward is 90% to Masternodes and 10% to Miners. After block 43200 the reward is split 80% to Masternodes and 20% to staking.

Since Bastiat didn't post this today, I would like to post it again because it's necessary.
TL/DR
Bitcoin users can help lower transaction fees and improve Bitcoin by switching to SegWit addresses and encourage wallets and exchanges to do the same.
SUMMARY
Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous Bitcoin transactions ([Understanding Segregated Witness]1 ). Since that time wallets and exchanges have been slow to deploy SegWit, some admitting in December 2017 that they have not even started work on integrating it. Others, such as Zebpay in India [have already implemented SegWit]2 and are reaping the benefits of reduced transaction fees. If Bitcoin users demand SegWit now it will temporarily relieve the transaction backlog while more even more advanced solutions such as Lightning are developed.
Batching is another great way that exchanges can reduce their fees. See: [Saving up to 80% on Bitcoin transaction fees by batching payments]3 . Despite the benefits of batching, some exchanges have been slow to implement it.
There is an opportunity now for all Bitcoin users to individually contribute to help strengthen and improve the Bitcoin protocol. At this point, the process requires a bit of work/learning on the part of the user, but in doing so you'll actually be advancing Bitcoin and leaving what could turn out to be a multi-generational legacy for humanity.
MEMPOOL/SEGWIT STATISTICS
BACKGROUND
On Dec 18 Subhan Nadeem has pointed out that:
[If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 180,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again]7 .
A few thousand Bitcoin users from /Bitcoin switching to making their next transactions SegWit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy SegWit for everyone ASAP. Let's make 80%+ SegWit happen fast. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of Bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to Bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing Bitcoin through non-SegWit ready exchanges that are harming Bitcoin.
  4. Spread the word! Contact individuals, websites, etc that use Bitcoin, explain the benefits of SegWit to everyone, and request they make the switch
IMPORTANT NOTE: The mempool is currently still quite backlogged. If you are a long-term holder and really have no reason to move your Bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your Bitcoins to a SegWit address or SegWit friendly exchange.
SELECTED TOP EXCHANGES BY BATCHING & SEGWIT STATUS
Exchange Segwit Status Batching Status
Binance NOT READY Yes
Bitfinex Ready Yes
Bitonic Ready Yes
Bitstamp Deployed Yes
Bittrex ? Yes
Coinbase/GDAX NOT READY No
Gemini Ready No
HitBTC Deployed Yes
Huboi ? ?
Kraken Deployed Yes
LocalBitcoins Deployed Yes
OKEx ? ?
Poloniex ? Yes
QuadrigaCX Deployed Yes
Shapeshift Deployed No
Note: all exchanges that have deployed SegWit are currently only sending to p2sh SegWit addresses for now. No exchange will send to a bech32 address like the ones that Electrum generates
[Source 1: BitcoinCore.org]8
[Source 2: /Bitcoin]9
Official statements from exchanges:
  • Bitonic: [SegWit: In testing (including send from bech32). Batching: Have been for years. ]10
  • Kraken: [Deposits are made to Segwit addresses and withdrawls are sent in Segwit format, but frontend presentation is pending full implementation/support in wallets such as bitcoin core.]11
  • Shapeshift: [We don't order batch, but we will get to it. So much engineering to do :/]12

FAQs
Where can I get a fee estimate for a SegWit transaction?
  • [Here's a good website that could help.]13
How can I get a SegWit address from my Bitcoin Core wallet?
  • Currently, Bitcoin Core hasn't implemented a way to get a SegWit address using the GUI. But you can get a receiving SegWit address using the debug console. To do it, go to the "Receive" tab and copy a receiving address (it starts with 1). Then just click Help > Debug window > Console and type: addwitnessaddress addr
  • You should replace addr with the receiving address that you just copied. Tap enter and you'll get an address (starts with 3). This is your SegWit address. You can use this one to receive funds. When you spend from this address, it will be a SegWit transaction. Easy huh?
If I'm a HODLer, will it help to send my BTC to a SegWit address now?
  • No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unneccessary transactions for now.
Why is SegWit adoption going so slowly? Is it a time-consuming process, is there risk involved, is it laziness, or something else?
  • SegWit will require some extra work to be done right and securely. Also, most exchanges let the user pay the fee, and up to now users have not been overly concerned about fees so for some exchanges it hasn't been a priority.
Once Segwit is FULLY adopted, what do we see the fees/transaction times going to?
  • Times stay the same - fees will go down. How much and for how long depends on what the demand for transactions will be at that time.
What determines Bitcoin transaction fees, to begin with?
  • Fees are charged per byte of data and are bid up by users. Miners will typically include the transaction with the highest fee/byte first.
Can you please tell me how to move my Bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
  • The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download Electrum v3.0.5 to generate a SegWit address.
    A transaction between two SegWit addresses is a SegWit transaction.
    A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.
    A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Tx if the sending address is a SegWit address.
    [Source: HowToToken]14
What wallet are you using to "batch your sends"? And how can I do that?
  • Using Electrum, the "Tools" menu option: "Pay to many".
    Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.
Why doesn't the Core Wallet yet support SegWit?
  • The Core Wallet supports SegWit, but its GUI doesn't. The next update will likely have GUI support built-in
Why isn't a large exchange like Coinbase SegWit ready & deployed when much smaller exchanges already are? Why do they default to high fees? Where is the leadership there?
  • Draw your own conclusions based on their own words:
    [March 2016 - Coinbase CEO Brian Armstrong has reservations about Core]15
    [Dec 2017 - Coinbase is STILL working on Segwit]16
P2SH/bech32 FAQs
What are the two SegWit address formats and why do they exist?
  • It's been a challenge for wallet developers to implement SegWit in a way that users can easily and without too much disruption migrate from legacy to SegWit addresses. The first wallets to enable SegWit addresses – Ledger, Trezor, Core, GreenAddress – use so-called “nested P2SH addresses.” This means they take the existing Pay 2 Script Hash address – starting with a “3” – and put a SegWit address into it. This enables a high grade of compatibility to existing wallets as every wallet is familiar with these addresses, but it is a workaround which results in SegWit transactions needing around 10 percent more space than they otherwise would.
    Electrum 3.0 was the first wallet to use bech32 addresses instead of nested p2sh addresses.
    [Source: BTCManager.com]17
What is the difference in address format between SegWit address formats P2SH and bech32?
  • P2SH starts with "3..."
    bech32 starts with "bc1..."
Which addresses can I send from/to?
  • P2SH Segwit addresses can be sent to using older Bitcoin software with no Segwit support. This supports backwards compatibility
    bech32 can only be sent to from newer Bitcoin software that support bech32. Ex: Electrum
    [Source: BitcoinTalk.org]18
Why did ThePirateBay put up two Bitcoin donation addresses on their frontpage, one bech32 and one not?
  • The address starting with a "3..." is a P2SH SegWit address that can be sent BTC from any Bitcoin address including a legacy address. The address starting with a "bc1..." is a bech32 SegWit address that can only be sent to from newer wallets that support bech32.

PREVIOUS DAY'S THREADS
There's lots of excellent info in the comments of the previous threads:
  • [Day 1: If every Bitcoin tx was a SegWit tx today, we'd have 8,000 tx blocks & the tx backlog would disappear. Tx fees would be almost non-existent once again.

  • [Day 7: I will post this guide regularly until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and tx fees are low. Refer a friend to SegWit today. There's no $10 referral offer, but you'll both get lower fees and help strengthen the BTC protocol]27
  • [Day 8: I will post this guide regularly until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and TX fees are low. Do you want low TX fees? This is how you get low TX fees]28
