Ultimate glossary of crypto currency terms, acronyms and abbreviations

I thought it would be really cool to have an ultimate guide for those new to crypto currencies and the terms used. I made this mostly for beginner’s and veterans alike. I’m not sure how much use you will get out of this. Stuff gets lost on Reddit quite easily so I hope this finds its way to you. Included in this list, I have included most of the terms used in crypto-communities. I have compiled this list from a multitude of sources. The list is in alphabetical order and may include some words/terms not exclusive to the crypto world but may be helpful regardless.
2FA
Two factor authentication. I highly advise that you use it.
51% Attack:
A situation where a single malicious individual or group gains control of more than half of a cryptocurrency network’s computing power. Theoretically, it could allow perpetrators to manipulate the system and spend the same coin multiple times, stop other users from completing blocks and make conflicting transactions to a chain that could harm the network.
Address (or Addy):
A unique string of numbers and letters (both upper and lower case) used to send, receive or store cryptocurrency on the network. It is also the public key in a pair of keys needed to sign a digital transaction. Addresses can be shared publicly as a text or in the form of a scannable QR code. They differ between cryptocurrencies. You can’t send Bitcoin to an Ethereum address, for example.
Altcoin (alternative coin): Any digital currency other than Bitcoin. These other currencies are alternatives to Bitcoin regarding features and functionalities (e.g. faster confirmation time, lower price, improved mining algorithm, higher total coin supply). There are hundreds of altcoins, including Ether, Ripple, Litecoin and many many others.
AIRDROP:
An event where the investors/participants are able to receive free tokens or coins into their digital wallet.
AML: Defines Anti-Money Laundering laws**.**
ARBITRAGE:
Getting risk-free profits by trading (simultaneous buying and selling of the cryptocurrency) on two different exchanges which have different prices for the same asset.
Ashdraked:
Being Ashdraked is essentially a more detailed version of being Zhoutonged. It is when you lose all of your invested capital, but you do so specifically by shorting Bitcoin. The expression “Ashdraked” comes from a story of a Romanian cryptocurrency investor who insisted upon shorting BTC, as he had done so successfully in the past. When the price of BTC rose from USD 300 to USD 500, the Romanian investor lost all of his money.
ATH (All Time High):
The highest price ever achieved by a cryptocurrency in its entire history. Alternatively, ATL is all time low

Block:
A package of permanently recorded data about transactions occurring every time period (typically about 10 minutes) on the blockchain network. Once a record has been completed and verified, it goes into a blockchain and gives way to the next block. Each block also contains a complex mathematical puzzle with a unique answer, without which new blocks can’t be added to the chain.
Blockchain:

## Pundi X Q2 2019 Highlights
* Pundi X has integrated more public chains into our products. In Q2, we completed integration of Binance Chain. NEM chain is in the work. As of today we’ve launched BNB, the Binance Chain native Coin and XEM, NEM native coin on Pundi X payment platform. We will integrate at least one more public chain in Q3.

## On XPOS
* **Where are we on official global location of XPOS?**
Zac: We have made a map on our official website that merchants can self report and feature their locations. It’s at [https://www.pundix.com/product\](https://www.pundix.com/product). We’ll be increasing and updating the map once we have permission form the merchants to update their locations.
* **The marketing from pundi has shifted from 100,000–700,000 xpos units by 2021 to 100,000. I understand the bear market has affected this but please share the strategy moving forward to hit your goal. How do you feel about hitting this goal?**
Zac: The 100K XPOS target has always been the initial goal and it’s stated in our whitepaper. And we are still working on achieving the goal by the end of 2021. Part of our growth strategy is to also explore the possibility to port our platform to traditional POS manufacturers to increase the adoption, which is ongoing at the moment.
* **1 year ago you sent 5000 XPOS somewhere. When, at least half of them, will be working? 3 year target was 100,000 by 2021. Now we have only 150 units, how do you expect to reach this goal?**
Zac: Yes, we have shipped thousands of XPOS to over 30 countries in the world. The 150 you’ve mentioned are the featured merchants which are published on the map. The active XPOS devices are deployed over 33 countries and we are actively talking to B2B partners to have higher wholesale and big deployments.
* **How many XPOS are live and used?**
Zac: We have gone through a very serious bear market, and some of the initial inbound requests for XPOS are not delivered. However, we are working slowly but surely with our Business Development team to not just roll-out into individual buyers, such as what we did on Pizza Day, but also to B2B partners. With the certifications approved, that will also help us to officially roll out to some of the key markets.
Individual merchants can use XWallet collection feature to accept crypto payment with QR code. For the merchants who have physical offline storefronts, they can use XPOS to enable the instant crypto transaction seamlessly. Moreover, as mentioned previously, we are exploring the integration on leading traditional POS terminal so that their distributors have option to enable crypto transaction feature. As for the challenge to adopt XPOS, it is the regulatory compliance in different countries. For this, our legal team think ahead and encourage our merchants to complete KYC.
I must be very honest to say the activation takes longer time than we expect but it will be worth at the end.
* **What’s the average number of transactions per xpos in use?**
Zac: The transaction number has increased very well. The number of each XPOS differs, due to the frequency of using crypto currency to purchase item or crypto assets. There’s no standard answer to this, but overall we see the transaction number and volume are going up.
* **How do you plan to reach the target of 100,000 by 2021?**
Zac: One of the challenges that we have is regulatory compliances in different countries. There are certain markets that do not allow crypto currencies and some require a clear approval for us to deploy XPOS. We are working on both challenges by talking to governments and applying for certifications. So how we plan to reach 100,000 XPOS user by 2021 is to work with distributors, B2B partners on a government / business level, and with existing POS companies to integrate our software solution into the system.
* **We understand as there was bear market and hence Xpos usage demand was low. Are you guys seeing growth of Xpos usage with current market conditions. Can you guys put some statistics comparison like last 30 days Xpos usage vs any month from bear market usage?**
Zac: It is very clear that as we moved out from the bear market, the demand for XPOS has been increasing. As we’ve shared just now both the transaction number and volume of Q2 have beaten Q1. We’ll be able to share more transaction numbers once we receive approval from our XPOS merchants.
One exciting thing is that, with the listing of different tokens, we also see users using these tokens as a way to transact on XPOS, which means we will be having more ways to transact and this is a growth point for XPOS.
* **When will there be more details for XPHONE and XPOS HANDY?**
Zac: For XPOS handy, we have finished production and it will be released in Q3
* **When will the iOS version of XWallet and XPOS be fully translated to other languages?**
Zac: Right now, the XWallet has Traditional Chinese, Korean, Spanish, German and English. With the latest version update, it now includes Portuguese. XPOS also comes with many languages and we hope to finish with more language, either working with professionals or volunteers. If you’re interested in volunteering, please contact us.
* **When will the Merchant back office have Product Registration and SKU id ability and also integrate with other POS software?** * **When will the top-up feature go away for XPOS to allow liquidity for XPOS**
Zac: We constantly update features in XPOS and merchant backend to make it easier for distributors and merchants to use. We understand that one of the ways for mass adoption is to enhance our distributor management system. With that, the distributors can manage manay XPOS at one time with different merchants.
Please stay tuned as we announce more and more functions of this feature.
## On Dubai
* **When will we see the deployment of the XPOS in Dubai?** * **Can we spend NPXS on the Dubai XPOS?**
Zac: As with all big projects there are a lot of moving parts, that includes working very closely with the local government, in Dubai’s case, the Credit Bureau of the Finance Ministry. Things are progressing for the Dubai project but due to confidentiality agreements with the parties involved, we cannot reveal much. All we can say is that we and our Dubai partners are working hard to have XPOS roll-out in the Dubai market and the UAE.
We are also discussing aggressively with Dubai partners whether to include crypto assets in the XPOS in Dubai. That clearly will involve local compliance and legal for that to happen.
* **Your system upgrades expect merchants to have downtime on their XPOS terminals, can you explain if you plan to run a business why this would be considered feasible (specially at the rate you have been doing your upgrades)?**
Zac: Yes, the benefit / strength of the XPOS is that most of the updates can be done on the fly. For example, when we have a token update on our XPOS where developers submit their tokens on Open Platform, the updates of this token are on the fly, which means that once we approve the token on our Open Platform, it will automatically appear on XPOS without any software updates.
The great thing that we believe about XPOS is not just the support of crypto assets, but also the ability to update most things on the fly, which means that whenever we have a good feature or a new token, the updates will be done instantaneously.
* **Can you guys arrange at least a community voting which is the next blockchain we would like to see next in XPOS? Voting will help to prioritize to chose the projects.**
Zac: One of the reasons why BNB is being listed on the XPOS is simply because of its popularity and also our user demand, in a way that we are already answering to our community’s request.
Right now, our main focus is getting all the tokens submitted on Open Platform to be listed on the XPOS. The submission process includes legal and compliance valid, so our legal and compliance teams are working hard to make sure that we have more tokens to roll out onto Open Platform, which means that they will be on XPOS, XWallet, and XPASS.
As to a specific voting mechanism, we’d like to consider that and hopefully we’ll be able to run a specific voting for the chain which users would like to see.
* **While comparing Xpos handy to Square POS devices at least with mobile it’s very cheap like under $30 and easy to use. When can we expect such light weight and cheaper version for XPOS? Is team working on such devices ?**
Zac: There are different POS companies around the globe and pour focus is to work with these POS companies with our software, so that a crypto sales feature will be part of the existing POS system. The more support of crypto asset usage using our software on existing POS, the better it is for global adoption.
We actually strongly believe that the pricing of our POS system is competitive in the market. And one of the great features of the XPOS is that the merchants will not need not to pay a certain percentage to existing acquirer but to be able to earn certain percentage from each transaction. That is the key differentiator for merchant to want to adopt this.
* **From the website with some of the key Countries for XPOS adoption looks great. However, the concern is for Venezuela, there is no reference link like the others have. Can you guys add the link with details to clear the ambiguity?**
Zac: Let’s give a little bit more patience so that we can actually release more information about our Venezuelan partnership. The good news is that we expect concrete news from Venezuela in the coming 2 weeks. So stay up-to-date about our Venezuelan roll out on XPOS, the best way is to subscribe to our telegram group for Venezuela.
## On Partnerships
* **Are there some major partnership in the works? I’m also interested in how you do immediate transactions? Do you anticipate scaling issues?**
Zac: The way XPOS is being designed is that when you use your crypto assets to purchase, it will have instantaneous confirmation because the action is an off-chain process. An on-chain action happens when a user who owns crypto assets in our system transferring the assets out of the Pundi X ecosystem to their own wallets; or to transfer crypto assets in Pundi X from an off-chain to a private wallet, which we will have very soon on XWallet itself.
That is why we are able to handle scaling. When a person wants to use crypto currency to buy a coffee, the transaction will happen instantaneously.
For specific partnership, especially with B2B partnership, we oblige to the NDA that we have signed. But if you follow us closely, you’ll know that we go to different parts of the world, talking to major companies to try to land more deals so that NPXS usage will increase dramatically.
* **Any big partnerships for making xphone or using the software for xBlockchain?**
Zac: These partnerships are also subjected to NDA, so please be patient for us to release more news.
* **When will XPOS have approval to process Visa and MasterCard payments?**
Zac: We have met representatives from these players including some of the key management people. They are obviously looking into crypto currency attentively, and we hope that there’s something we can do with MasterCard and/or Visa.
This is something that the community has suggested and we agree fully. Please allow us with some time to work on this. We have also showcased XPOS to the CEO of MasterCard. For what or when will anything happen, please wait for our official announcement.
* **What’s the status on Quantum fund and their contribution or involvement with Pundi’s project?**
Zac: We announced last year that we are creating a fund to invest in projects beneficial to our ecosystem. We’ve identified some interesting projects, and we have invested in at least 1 project. The reason why we’re investing in that project is because of the services that it will bring onto the Pindi X ecosystem. So the purpose of the investment of the companies is that these companies in turn will benefit on our ecosystem. This is our key consideration.
The team has evaluated the projects that will benefit the Pundi X / Function X ecosystem. Vic and his team will be able to reveal more details on the companies we have invested in and how they will contribute to our ecosystem in Q3.
* **Recent update on NPXSXEM is highly ambiguous as mentioned that it will be now BEP token and later once FX goes live it will get back to Fx platform. Why you guys had so rush to use Binance chain only for few months? Isn’t you guys switching to much in a short time span?**
Zac: Liquidity and utility have been an issue for NPXSXEM. Due to the design philosophy and the limit of token that can be created on NEM’s smart contract, we are only able to create a small number of tokens on NPXSXEM. By moving into the Binance chain for NPXSXEM, the BEP2 token version will be able to support all the NPXSXEM tokens, which means that we’ll migrate and also be able to make sure all the NPXSXEM tokens are under the same contract address.
We believe with the strong liquidity, we will be able to give our NPXSXEM token holders a good reason of what the token holders have been waiting for. We hope to bring NPXSXEM to match the level of NPXS.
* **When #XRP?**
Zac: Our OpenPlatform is a currency agnostic platform, which means that we will work on integrating public chain as well as tokens that are most requested by the users. We’ll also be looking into the listing of different tokens that are being mentioned by the community.
As said, we will have at least one more public chain integration in Q3, perhaps even more.
* **Are you as a company going to try and connect with libra? If they have said they want to be a payment remittance service, have Square, PayPal, Visa on board I as an investor would prefer you try to join them rather than beat such large competitors**
Zac: Of course, we’ll be delighted to work with Facebook and also the Libra coin. Pundi X and XPOS is a currency agnostic / currency neutral platform, if there’s opportunity to list Libra coin or work with Facebook in different ways to promote crypto currency adoption, we’ll certainly look into that and work on reaching out to them.
## On Trading
* **Can you confirm during AMA, Pundi team is not involved with any trading with their own token like selling over time to manage the fund to run the company.**
Zac: All the wallet addresses of the team holdings are disclosed and transparent. This is one of the first things that we did after ICO. Hence, our token holdings are transparent and everyone can monitor our fund transactions. Also, we have strict internal financial regulation and compliance, shows that we are here to build a long-term project.
The best way to make NPXS or the NPXSXEM to rise is real daily life use case.
* **When will you stop manipulating NPXS chart?**
Zac: Our focus has always been and will be building great products. The more product usage, the demands for NPXS and NPXSXEM will increase. Let’s address again that, Pundi X the company is NOT involved in any manipulation of the NPXS price.
There are trading teams, market makers, financial institutions that profit from the drop and rise of token prices in the crypto market. The good thing about NPXS is that we have managed to create a high liquidity by listing on 40+ exchanges and having global trades and demand from all over the world. We hope this and coupled with the fact that we are a solid product and roll out the use cases, the demand of NPXS will only continue to rise and will be able to deter any of the traders or speculators there is for NPXS.
These traders gain profit from manipulating tokens whether BTC or other tokens. In fact, the traditional financial markets have similar challenges as well. What I want to stress is that, we at Pundi X, do NOT speculate or manipulate the price. We work very hard to create demands for NPXS and as a company, it is only beneficial for us to see the prices of NPXS and NPXSXEM rise.
* **Can we please address the elephant in the room which is the Binance bot with huge sell walls and buy walls causing huge distress and concern among users?**
Zac: First, I cannot confirm nor deny that whether Binance has a bot. I think this is something that you need to ask Binance. We need to work with Binance because Binance has one of the biggest liquidities, if not the greatest liquidity, for NPXS. The best way to counter manipulators is to create more use case, more demand and more acceptance of our tokens.
* **Why on almost all exchanges do you not offer a USDT trading pair?**
Zac: We have USDT trading pairs on Bittrex, Bittrue, and more. In addition, we have fiat pairs in Korean Won, IDR, INR, and Turkish liras. We will continue to work on adding trading pairs for NPXS to make it more liquidate.
* **Why don’t you offer a stable coin sell and purchase on the xpos to help with adoption? Places in Africa with volatile currencies would go crazy for this.**
Zac: It’s a great observation. This is a request that’s been asked from many users. We’re working on stable coin listing on XPOS and hopefully it’ll come soon. Stable coin requires a greater compliance and legal validate, which we have been working on since months ago and we hope to have the stable coin up in XPOS soon.
* **When will you add an active tracker for coin burn, whether its measured in usd, NPXS or whatever you choose. The community has been asking for this on twitter, reddit and telegram for this entire year.**
Zac: It will be hard for us to have a daily tracker of the coin burn, but what we might be able to work on is a tracker which have shown all of the tokens that have been removed from the usage. Thank you for giving us this great suggestion and we will work on it in some form.
Zac: Our token supply has always been specified in our white paper, and as promised in our white paper, we will continue to remove tokens through usage and use cases, which we’re working on all the time.
* **Price movement. When will NPXS go to which price?**
Zac: We cannot comment on the change of the price. Our focus is on building products. We hope by doing that the NPXS value will go up. Again, there’s no way that we can comment on the price.
**I believe that burning tokens every 14 weeks keeps the price suppressed and will only lead to huge pumps and dumps. Imo, If the burns were more frequent, the price would move organically.**
Zac: We continue removing tokens quarterly per advised by our legal and compliance team.
**Is it mandatory npxs swap? What happens for token we have in binance?**
Zac: No it’s not a mandatory NPXS swap for FX.
**How many NPXS or NPXSXEM was converted?**
Zac: In Q2, we will remove 29B NPXSXEM and 9B NPXS.
## On XWallet
* **Why not put in XWallet like the place where we can buy and sell like restaurants and shops?**
Zac: You are correct. In fact, if you look at XWallet, there is a merchant feature, whereby you can register as a merchant. By becoming a merchant, you will be able to print out your QR code and stick it on your restaurant. People are able to make payment through this QR code. This will act like a mini-XPOS.
* **In addition to that having multiple different blockchain in XWallet will increase the XWallet adoption. Hence, we would like to see aggressive game plan and execution from the team and would like to hear that**
Zac: That’s a great suggestion. Every day we want to increase use cases for XWallet. In fact, our XWallet update is one of the most frequent in the market. Within 5 months, we have over 10 updates on iOS and Google Play. This does not include soft update which happens every several days. In my view, the effort is very tremendous.
* **Is there any plan to add Swap option within XWallet so that people can trade the coins within XWallet?**
Zac: Yes, there’s such plan and in fact there is an upcoming feature that people will be able to use coins in XWallet to exchange into other things. The exact form and format have not been reviewed. We hope to share more when we have concrete example. But what you suggested is what we are planning for months ago.
* **When will XPOS and XWallet have fiat on ramps?**
Zac: This is a good question. It’s not only involved with regulatory compliance but also involved the technical part. This is also something we are planning for months. Once approved, hopefully we are able to support fiat currency on ramps and off ramps on XWallet.
**On Others*\*
* **How is the internal organization doing? Currently how many employees work for Pundi? Currently how many job positions are open?**
Zac: Pundi X has grown tremendously. We are now having over seven offices around the globe. I’m sitting in the Singapore office. We have office in Jakarta, Taiwan, Tokyo, Shenzhen, São Paulo and London. These are the places we have physical offices and house approximately 100 full time employees of Pundi X.
The positions open from Pundi X are legal associate in Singapore and other offices. We are looking for more R&D people, especially in Taiwan. We are looking at marketing and PR people in different parts of the world. And we are looking for POS distributors. As a POS distributor, you will work with our business development team and also our technical team to roll out many XPOS which you have a network to control in your local market.
* **Would you consider removing the KYC to allow u.s. holder to stake and be rewarded?**
Zac: We would love to have more users, including US. However, our compliance and legal advisors have not allowed us to accept US holders to stake and be rewarded.
I’m sorry to say that but this is after serious consideration to make such a decision. In fact, it is a very hard decision because we have healthy user base in the US.
will continue to monitor the situation in the different markets and be compliant. There are also ways to be rewarded when using XWallet service without KYC. We are looking into to explore more on this and launch new features. Hopefully we are able to bring the beta version for you to test this week or next.
**On XPhone*\*
* **Where are we on pre-sale announcement of Xphone? It was highlights of Q2 goal. If we are getting delay, that’s ok. But at least community will have some clarification why it’s getting late and when approximately it coming?**
Zac: Pre-sale order will start this month. It’s likely the end of July. Pre-sale will take place in different channel including the official website and XWallet. Apart of our own channel, the pre-sale will go live on a 3rd party channel. People will be able to pre-order crypto either in crypto or in fiat.
* **Can you discuss in AMA, is participants can pay with Crypto or Credit/debit card or in both ways?**
Zac: As a crypto company, we prefer payment in crypto, but fiat, Visa, MasterCard, and other traditional payment methods will be accepted on different pre-order channels. Stay tuned for pre-order which will happen in late July.
* **Will the Xphone be open to purchase in all regions of the world?**
Zac: Yes, pre-orders will be able to be done on-line, and products will be shipped from our offices to users in different parts of the world.
* **Will the blockchain mode on the Xphone be operable during the testnet or will this function not work until mainnet?**
Zac: XWallet and XPhone are the first channel and avenue for Function X testnet, so once the testnet is operateble, we will start to engage certain services on XWallet and XPhone into Function X testnet, and ultimately into mainnet. Slowly but surely.
* **Does Xphone have hard protective cover,extra Sim slot, also is it enhanced with ip68 water rating?**
Zac: XPhone will not be waterproof, so please do not submerge XPhone into water. XPhone will definitely be eavesdrop-proof because we’re using a blockchain mode, only you and you control your own conversation.
* **Which country accept the Xphone?** * **Will I also be able to use the SIM-card?** * **The blockchain modus will work in every country (what in the absense of nodes)?** * **Will the XPhone I buy now support updates in the future?**
Zac: People from any country will be able to buy XPhone on-line. You will be able to use a SIM for we have built a SIM slot. Wherever you are, the XPhone can be turned on to become a node.
Will XPhone support future updates? Yes, of course. Just like the XPOS, we support silent update. It will be like how we support XPOS, many updates. The updates will always be supported on XPhone.
**On Function X*\*
* **When is the detail white paper coming for FunctionX? Why the team is very resistive to have well documented white paper? We need scientific approach and well documentation on FunctionX to have developers to be more involved.**
Zac: Yes, developer involvement is a key criterion of the growth of Function X. We have done 2 things, one is that we have set up Function X Foundation which is led by David Ben Kay and will involve third party adviser and board members. Second, we have set up a developer relations team led by one of our own members as well. This team will work on creating developer documents, developer demos and sample, so that excellent developers can tap into working with Function X resources.
The first version of developer documentation is ready in English and Chinese. We are still polishing up the documents and hopefully to release them soon.
We are also working with third party developers, and are engaging at least 2 third party developer companies, so that we can help create their services on Function X and also XWallet.
We are hoping to showcase a smooth and usable service to the audience, we think this is the key criterion of the Function X growth.
Thank you for this suggestion. We need to update more often on github developer documentation as well.
As for the white paper, we did not have one per se because Function X did not do an ICO. But we will continue to update our white paper and include not only technical details, but also details on the chain and how we can get more developers and users so that the future hardware will be added as a node and you will be rewarded financially, at least through our ecosystem genesis fund. Please stay tuned and there are a lot of things going on in the company. Each and one of us is working hard.
* **Why does the FX ecosystem need a decentralized OS?**
Zac: The mantra of Function X is decentralization and having private control of your data. A full private control of your data comes with a decentralized system not just in transmission of your data, but with the operating system built fully for decentralization , which includes a transmission protocol replacing http. The apps uploaded into Function X will be decentralized as well as the data that is stored on the app, which means that how BitCoin or crypto assets are verified on different nodes will also be part of the way we store data and content.
The decentralized OS is key to fulfilling a decentralized environment for a more private and free usage.
* **What about FX are you most excited about?**
Zac: We are actually creating a shift of how people view of blockchain and how decentralization is not just about transacting commercial commodity, but also data, including your identity, are all decentralized. That is what we are most excited about.
The only way for us to achieve this is to have developer support, for we need the developers to build on the foundation we have to offer those exciting services.
* **We understand that developing a new blockchain is time consuming. As a community we are in a dark space to understand where exactly the development of FX right now.**
Zac: We are working hard on creating the testnet and eventually the mainnet. For the latest updates of Function X, what I can encourage you to do is to go on and subscribe to the Function X telegram group where discussions are made. We have formed the Function X Foundation and created the developer relations team, so that the Function X progress will go smoother and with more partnership from outside, whether it’s developers, third party companies, teleco, etc.
* **When FX goes live on the mainnet, will FX coin be used to stake and earn NPXS? how will staking work on that new mainnet?**
Zac: The NPXS/NPXSXEM staking will last till March 9, 2020 as announced. What we are committed is to create more use cases. For FX tokens, the use cases will be focusing on the Function X Chain and the use cases on Function X that include DApp on Function X and different hardware/software services.
* **When fx testnet will be available?**
Zac: First I would like to thank you for your constant support. In Q3, we plan to open Function X testnet so that we will be migrating and creating certain use cases that can be used on Function X testnet, starting with our own XWallet. Which means, the XWallet will migrate some features into Function X testnet, and slowly followed by our other Pundi X products, including XPhones, XPASS, Open Platform and Function X own developer related products from third parties.

Logs of yesterday's dev meeting

 Dev meeting?  Would say so, yes  The people are still exhausted from the payment ID meeting :)  Guess we could ping some people  vtnerd, moneromooo, hyc, gingeropolous, TheCharlatan, sarang, suraeNoether, jtgrassie  Anyone up for a meeting?  Yep I'm here  Here  o/  Perhaps we should just start and people will eventually hop in?   oof   sorry guys, I'm working on the new FFS and I forgot all about this. Got a couple of new volunteers.   This literally might be able to launch tomorrow.  I know that. It's called "flow" :)  I could run if you're out of time?   go for it dEBRUYNE   you guys are going to like this new FFS. We're like 99% done.  Hi  rehrar: someone else do the milestone thing already?  All right, jtgrassie, perhaps you'd to start w/ briefly describing your most recent PR? https://github.com/monero-project/monero/pull/5091   oneiric, xiphon did everything   like....everything  As far as I can see, it allows the user to push his transaction over I2P, thereby masking the origin IP of the sendeuser  great  And it hooks into vtnerd's PR right?  Sure. It basically just builds on vtnerds Tor stuff.  sorry dEBRUYNE  Really not much added.  I have it running and tested.  From the perspective of the user, what needs to be configured exactly?  Nice  Assuming the PR is included in the release binaries  I'm using knacccs i2p-zero duirng testing but will of course work with any i2p setup   sorry dEBRUYNE <= Np  Looks a little like dams breaking, now that we have some dark clouds over Kovri and people take matters into their own hands ...  User needs to run i2p, expose a socks service and and inbound tunnel.  Basically same as Tor  Okay, so should be reasonable as long as we write proper documentation for it (e.g. an elaborate guide)  rbrunner, yes, knaccc credit for jumping on i2p-zero really  dEBRUYNE: documentation monero side is kindof done. i2p side is very much implementation specific.  I suppose we could write some guides for the most popular implementations?  e.g. i2p-zero aims to be zero conf, but i2pd or Kovri would be differnet.  I see, great  vtnerd___: Do you want to add anything?  could amend the current kovri guide for monero use from --exclusive-peer to the new proxy support  Now I have i2p-zero running and tested with the #5091, I plan to jump back over to helping knaccc on getting that polished.  I added support for socks proxy in the basic wallets  ^ excellent  Yes vtnerd___ I havent tested it yet but looks sweet.  So connections to `monerod` over Toi2p are possible within wallet cli and wallet rpc  Awesome  This also implies auth+encryption even if ssl is not in use (when using an onion or i2p address)  All right  moneromooo: are you here? If so, could you perhaps share what you've been working on?  I am.  I revived the SSL PR, more stuff on multi sender txes, an implementation of ArticMine's new block size algorithm.  I presume a multi sender tx works similar to multisig insofar as the senders have to exchange data before the transaction can be performed right?  Yes.  There are 2 SSL PRs. What's the diff?  Theoretically this would also allow the sender to provide an output right? Which would be kind of similar to Bitcoin's P2EP  The second one adds some things like selecting a cert by fingerprint.  Yes.  (for the first sentence)  All right, awesome  For anyone reading, this breaks the assumption of the inputs belonging to a single sender, which makes analysis more difficult  Nice side-effect.  Much work coming for the various wallets to support that  rbrunner: Anything you'd like to share in the meeting btw?  Yes, just a little info  I have started to seriously investigate what it would mean to integrate Monero into OpenBazaar  I have already talked with 2 of their devs, was very interesting  In maybe 2 or 3 weeks I intend to write a report  Too early to tell much more :)  Soon^tm I guess :)  Yep  Currently wrestling with Go debugging  whole new world  moneromooo: Has pony recently shared any insights regarding the upcoming 0.14 release btw?  No.  All right  I would love to see the tor & i2p PR's merged sooner rather than later so we can get more testing done.  ^ +1  Isn't that famous early code freeze already on the horizon?  fluffypony, luigi1111 ^  I suppose I could provide a little update regarding the GUI btw  As always, lots of bug fixes and improvements :-P  selsta has recently added a feature to support multi accounts  dsc_ has revamped the wizard and will now start working on implementing the different modes and a white theme  dsc_ is working fulltime on the GUI already?  yes  :)   dsc_ is bae  In light of the recent payment ID discussion, we've also, by default, disabled the option to add a payment ID unless the user explicitely activates the option on the settings page  rehrar ^  nice   I spoke about this yesterday at the coffee chat, this is not a good decision.  How does it handle integrated addresses? The same way?  rehrar ?   For the next many months, we are still stuck with PAyment IDs in the ecosystem. Making it harder for people to access them will make Monero suck so hard to use for the average person for many months.  i agree with rehrar   Remove the option of Payment IDs when we remove Payment IDs  rehrar: The new GUI release won't be live until probably mid march though  Which is a few weeks in advance of the scheduled protocol upgrade   Payment ID removal comes in October   right, but Payment IDs are not removed in March  Did we not have loose consensus on removing the old, unencrypted payment IDs in march?   they are removed in October  We had discussed a deprecation in March  and a ban in October   ok, then if we are going to do that, we have to commit to it and contact the exchanges like Binance that use them and get rid of them in the next few months  (of unencrypted)   Binance is huge, and if they still use them, then people will be very upset that they can't deposit or use Payment IDs easily   I'm just speaking from a UX perspective.  I thought it was unencrypted in April and possibly encrypted in October  Yes I do agree  Timeline and notes: https://github.com/monero-project/meta/issues/299  impossible to remove them for march, many exchanges still use them  We can defer it to the 0.15 release if needed  Well, that wasn't the impression for them log that I just read today  This was all discussed in the earlier meeting linked above   We have to force the ecosystem off of Payment IDs before we remove them from the UI, is all I'm saying  Remove != make difficult to use  ... or make them more difficult there, right?  ping sgp_   sarang, I understand, and I agreed with you during that meeting. But then I started thinking of it as a UX person, which I am.   And that huge massive problem leapt out at me  i think making them difficult to generate is a good idea but making them difficult to consume and use is a bad idea  well, maybe not a good idea, but a better idea   ^  If we defer the decision to depriciate long payment IDs to october, won't we have the same issue then?  The UI can gave an expandable payment ID field like MyMonero and we can still call it deprecated   It is foolhardy to remove an option that the ecosystem uses. So I suggest we keep the Payment ID in the UI until October when they are completely banned.   no dEBRYUNE, because they will be banned via consensus  sgp_ imo it may be a misdirection of dev resources to add that since things are proceeding in the short term rather than long term  but this is a relatively minor point  Nothing matters til exchanges change  All right   The issue is that consensus will still have them in April, and exchanges won't upgrade because they are still allowed. Thus they must still be in the UI.  endogenic these changes are already merged in the GUI to hide it like you do  ok   But when they are banned, exchanges are forced to upgrade or stop using Monero, so we can remove them safely because they won't be in use  rehrar: that's a strong assumption   sarang that they will upgrade?  yes   if they don't, then they can't use Monero  If exchanges require pid, users need a way to set a pid. Making it hard for the user in the interim is just going to be a nightmare.   we have decided to take our "stand" in October  A way that is not too hard, then  To be clear, we still intend to deprecate long encrypted payment IDs in April right? But no enforcement until October   the term "deprecated" doesn't mean much if it's still allowed, and used in popular places   yes, as far as I understand it   jtgrassie, exactly  True I suppose  dEBRUYNE: we need to be more specific when talking about deprecation   the person who suffers is the user  There are two proposals for GUI deprecation:  1. Hide it in the send screen with a simple option to expand (currently merged iirc)  2. Hide it completely in the send screen unless users enable the field in advanced settings (PR'd but not merged yet iirc)  What are the arguments for 2?   Both are poor options, but 1 is better than 2 by a long shot   Well the people who need to be made to "suffer" are the exchanges. And I don't see a way to make exchanges "suffer" other than by having their suffering customers complain to them constantly that they need to update.  ^  CLI has something similar where users need to set a manual payment ID transfer mode. Not sure if it's merged yet   the way to make the exchanges suffer is when we ban PIDs. They either upgrade or don't use Monero.  exact;y  Agree with rerahr here  have exchanges been provided with clear, practical, sufficient technical upgrade plans for supporting what they're doing with PIDs but with subaddrs?    Both are poor options, but 1 is better than 2 by a long shot <= I wouldn't call 1. a poor option. Have you actually checked how it looks?  Because it states "Payment ID" and a user has to click on the + to expand the field  endogenic: yes the email when out. Blog post coming soon, but contains the same info as the email  also the exhcnages' users are often using wallets that don't support subaddresses  ok great   as well, it should be noted that the timeline for exchanges to upgrade is September, not October when the fork is.  Which wallets are that?  Rehrar: I don't see option 1. causing any issues/confusion  i guess it doesnt matter too much if withdrawing as a personal user the main address should suffice   Because September is when the new versions will be coming out without PIDs in the UI  If there's opposition to 2, 1 is fine. We can still call it deprecated which is the optics we need anyway   exchange users are often just using other exchanges lol. No wallets involved.   dsc_ dEBRUYNE, ok, I trust you guys here then  rbrunner: i was thinking mymonero last i heard  Ok  pigeons: rbrunner yes receiving on subaddresses won't be supported yet  sending to them has been possible though  and yes as learnandlurkin says often they withdraw to other systems like exhcnages that also dont yet support subaddresses  I really can't come up with any good argument for 2. right now  endogenic: seems not much of an issue then. Exchanges will typically support withdrawals to both subaddresses and plain addresses (especially if we are going to force them to use subaddresses)  For deposits, MyMonero works properly if the user sends to a subaddress  Actually the second solution was already merged: https://github.com/monero-project/monero-gui/pull/1866  Maybe not enough eyes watching :)   The important thing is to have done something to justify having a big "DEPRECATED IN APRIL" stamp on PIDs to spook exchanges in the interim  This was for solution 1: https://github.com/monero-project/monero-gui/pull/1855   The Monero Community Workgroup will start making noise everywhere we can to exchanges, and everywhere else that will listen. Try to get on those garbage news sites also.   So everyone knows that deprecated in April, and banned in September  Hey, for solution 1, write "Payment ID (optional, deprecated)" or similar there  rbrunner: noted  rehrar: probably wait until the blog post, but it should only be a few days   Maybe a Reddit sticky post would be useful?   With the blog post   If people are over freaking out about the hashrate  or terabyte blockchain :)  sigh  Any questions for the MRL side?  Is someone checking ArticMine's block size changes for weird behaviour in some cases etc ?  How would such testing work? Private blockchain?  I'm waiting on cost information from ArticMine to complete the model  Or just simulations?  Also, smooth suggested a mean rather than median for the 100000 block op. It would indeed be much nicer if it doesn't make the change worse.  You mean computationally or what?  Nicer ? Yes.  no sorting needed for mean  I'll add a separate sim for that  Well, just nicer. Forger the much.  Forger the Much sounds like the formal name of a Lord of the Rings character  :)  To close the payment ID discussion, in essence, we agree that we shouldn't make it difficult for the user to add a payment ID right (until 0.15 is released)  ?  I don't. I did make it harder.  In the CLI, somewhat other story, I would say  than the GUI  People there are used to juggle with options and CL parameters  rehrar: I recommend opening another issue to reverse 1866 and we can gather feedback on it there  Sounds good, to me at least   Dudes, if I do a Jitsi stream right now to show the new FFS in action, would you guys be interested in watching it?  I'd watch it, if the meeting is formally done  sure  yeah, can I start one and record it?   I'll give it in like fifteen minutes   I'll let you all know, stand by  I have a question on tx_extra if no one else has anything to talk about  People have said you can put arbitrary data in there in whatever format you want as long as you're willing to pay for it. However, do you need to mine the transaction for it to be included? I didn't think nodes would block transactions with arbitrary tx_extra data  It'll be in nodes' txpool when you relay it. A wallet could see it before it's mined.  moneromooo: will it be mined though?  by others  Is it valid ?  assume it's otherwise valid  Does it have a high enough fee ?  assume it does yes  I ran into conflicting information here: https://monero.stackexchange.com/a/3627/42  Then it will probably be mined.  I once had the idea to put "my" MMS messages in there, looked at the code, and found no hard blocks for tx_extra data  That answer looks incorrect.  It is incorrect  If it will be mined, then that meets my assumption. There seems to be some misconception that people will not mine transactions with arbitrary tx_extra. I can add some comments there  And please don't spam it, and don't put fingerprintable stuff in it. It's meant to be here for *useful* stuff that's "uniform" enough.  It will be mined, whether a wallet *displays* the tx_extra is a different question.  I don't think any wallet currently displays that  it soes if its a pid  I think  Yeah, of course :)  Great, that answers my question

What is Quant Networks Blockchain Operating System, Overledger? And why are Enterprises adopting it at mass scale?
Overledger is the world’s first blockchain operating system (OS) that not only inter-connects blockchains but also existing enterprise platforms, applications and networks to blockchain and facilitates the creation of internet scale multi-chain applications otherwise known as mApps.
In less than 10 months since launching Overledger they have provided interoperability with the full range of DLT technologies from all the leading Enterprise Permissioned blockchains such as Hyperledger, R3’s Corda, JP Morgan’s Quorum, permissioned variants of Ethereum and Ripple (XRPL) as well as the leading Public Permissionless blockchains / DAGs such as Bitcoin, Stellar, Ethereum, IOTA and EOS as well as the most recent blockchain to get added Binance Chain. In addition, Overledger also connects to Existing Networks / Off Chain / Oracle functionality and it does all of this in a way that is hugely scalable, without imposing restrictions / requiring blockchains to fork their code and can easily integrate into existing applications / networks by just adding 3 lines of code.

What is a blockchain Operating system?

You will be familiar with Operating systems such as Microsoft Windows, Apple Mac OS, Google’s Android etc but these are all Hardware based Operating Systems. Hardware based Operating Systems provide a platform to build and use applications that abstracts all of the complexities involved with integrating with all the hardware resources such as CPU, Memory, Storage, Mouse, Keyboard, Video etc so software can easily integrate with it. It provides interoperability between the Hardware devices and Software.
Overledger is a Blockchain Operating System, it provides a platform to build and use applications that abstracts all of the complexities involved with integrating with all the different blockchains, different OP_Codes being used, messaging formats etc as well as connecting to existing non-blockchain networks. It provides interoperability between Blockchains, Existing Networks and Software / MAPPs

How is Overledger different to other interoperability projects?

Other projects are trying to achieve interoperability by adding another blockchain on top of existing blockchains. This adds a lot of overhead, complexity, and technical risk. There are a few variants but essentially they either need to create custom connectors for each connected blockchain and / or require connected chains to fork their code to enable interoperability. An example of the process can be seen below:
User sends transaction to a multi sig contract on Blockchain A, wait for consensus to be reached on Blockchain A
A custom connector consisting of Off Chain Relay Nodes are monitoring transactions sent to the smart contract on Blockchain A. Once they see the transaction, they then sign a transaction on the Interoperability blockchain as proof the event has happened on Blockchain A.
Wait for consensus to be reached on the Interoperability Blockchain.
The DAPP running on the Interoperability Blockchain is then updated with the info about the transaction occurring on Blockchain A and then signs a transaction on the Interoperability blockchain to a multi sig contract on the Interoperability Blockchain.
Wait for consensus to be reached on the interoperability Blockchain.
A different custom connector consisting of Off Chain Relay Nodes are monitoring transactions sent to the Smart Contract on the Interoperability Blockchain which are destined for Blockchain B. Once they see the transaction, they sign a transaction on Blockchain B. Wait for consensus to be reached on Blockchain B.

Other solutions require every connecting blockchain to fork their code and implement their Interoperability protocol. This means the same type of connector can be used instead of a custom one for every blockchain however every connected blockchain has to fork their code to implement the protocol. This enforces a lot of restrictions on what the connected blockchains can implement going forward.

https://preview.redd.it/pe166qyexel31.png?width=1561&format=png&auto=webp&s=d4c982089276e64cd909537c9ce744b59e168b6d
Some problems with these methods:
  • They add a lot of Overhead / Latency. Rather than just having the consensus of Blockchain A and B, you add the consensus mechanism of the Interoperability Blockchain as well.
  • Decentralisation / transaction security is reduced. If Blockchain A and Blockchain B each have 1,000 nodes validating transactions, yet the Interoperability Blockchain only has 100 nodes then you have reduced the security of the transaction from being validated by 1000 to validated by 100.
  • Security of the Interoperability Blockchain must be greater than the sum of all transactions going through it. JP Morgan transfer $6 Trillion every day, if they move that onto blockchain and need interoperability between two Permissioned blockchains that have to connect via a public Interoperability blockchain, then it would always have to be more costly to attack the blockchain than the value from stealing the funds transacted through the blockchain.
  • Imposes a lot of limitations on connected blockchains to fork their code which may mean they have to drop some existing functionality as well as prevent them from adding certain features in the future.
  • Creates a single point of failure — If the Interoperability blockchain or connector has an issue then this affects each connected blockchain.
  • It doesn’t scale and acts as a bottleneck. Not only does building complex custom connectors not scale but the Interoperability blockchain that they are forcing all transactions to go through has to be faster than the combined throughput of connected blockchains. These Interoperability blockchains have limited tps, with the most being around 200 and is a trade off between performance and decentralisation.

But some Interoperability blockchains say they are infinitely scalable?

If the interoperability blockchain is limited to say 200 tps then the idea is to just have multiple instances of the blockchain and run them in parallel, so you benefit from the aggregated tps, but just how feasible is that? Lets say you want to connect Corda (capable of 2000+ tps) to Hyperledger (capable of up to 20,000 tps with recent upgrade). (Permissioned blockchains such as Hyperledger and Corda aren’t one big blockchain like say Bitcoin or Ethereum, they have separate instances for each consortium and each is capable of those speeds). So even when you have just 1 DAPP from one consortium that wants to connect Corda to Hyperledger and use 2000 tps for their DAPP, you would need 100 instances of the Interoperability blockchain, each with their own validators (which maybe 100–200 nodes each). So, 1 DAPP would need to cover the costs for 100 instances of the blockchain and running costs for 10,000 nodes…This is just one DAPP connected to one instance of a two permissioned blockchains, which are still in the early stages. Other blockchains such as Red Belly Blockchain can achieve 440,000 tps, and this will surely increase as the technology matures. There is also the added complexity of then aggregating the results / co-coordinating between the different instances of the blockchain. Then there are the environmental concerns, the power required for all of these instances / nodes is not sustainable.

It’s not just transactions per second of the blockchain as well, its the latency of all these added consensuses along the path to reach to the destination and not knowing whether the security of each of the hops is sufficient and can be trusted. To see examples of how this potential issue as well as others effect Cosmos you can see my article here. I recommend also reading a blog done by the CEO of Quant, Gilbert Verdian, which explains how Overledger differs here as well as detailed in the whitepaper here.

https://preview.redd.it/2cwj4k7hxel31.png?width=1169&format=png&auto=webp&s=d6fc49086f944089cef7ffa1dfc9d284107ad2e3

Overledger’s approach

In 1973 Vint Cerf invented the protocol that rules them all: TCP/IP. Most people have never heard of it. But it describes the fundamental architecture of the internet, and it made possible Wi-Fi, Ethernet, LANs, the World Wide Web, e-mail, FTP, 3G/4G — as well as all of the inventions built upon those inventions.
Wired: So from the beginning, people, including yourself, had a vision of where the internet was going to go. Are you surprised, though, that at this point the IP protocol seems to beat almost anything it comes up against?Cerf: I’m not surprised at all because we designed it to do that.This was very conscious. Something we did right at the very beginning, when we were writing the specifications, we wanted to make this a future-proof protocol. And so the tactic that we used to achieve that was to say that the protocol did not know how — the packets of the internet protocol layer didn’t know how they were being carried. And they didn’t care whether it was a satellite link or mobile radio link or an optical fiber or something else.We were very, very careful to isolate that protocol layer from any detailed knowledge of how it was being carried. Plainly, the software had to know how to inject it into a radio link, or inject it into an optical fiber, or inject it into a satellite connection. But the basic protocol didn’t know how that worked.And the other thing that we did was to make sure that the network didn’t know what the packets had in them. We didn’t encrypt them to prevent it from knowing — we just didn’t make it have to know anything. It’s just a bag of bits as far as the net was concerned.We were very successful in these two design features, because every time a new kind of communications technology came along, like frame relay or asynchronous transfer mode or passive optical networking or mobile radio‚ all of these different ways of communicating could carry internet packets.We would hear people saying, ‘The internet will be replaced by X25,’ or ‘The internet will be replaced by frame relay,’ or ‘The internet will be replaced by APM,’ or ‘The internet will be replaced by add-and-drop multiplexers.’Of course, the answer is, ‘No, it won’t.’ It just runs on top of everything. And that was by design. I’m actually very proud of the fact that we thought of that and carefully designed that capability into the system.
This is the approach Quant have taken with their Blockchain OS, Overledger to solve Blockchain interoperability. Compared to other Interoperability platforms that are trying to achieve interoperability at the transaction layer by connecting two blockchains via another blockchain, these will be ultimately be made redundant once faster methods are released. Overledger is designed to be future proof by isolating the layers so it doesn’t matter whether it’s a permissioned blockchain, permissionless, DAG, Legacy network, POW, POS etc because it abstracts the transaction layer from the messaging layer and runs on top of blockchains. Just as the Internet wasn’t replaced by X25, frame relay, APM etc, Overledger is designed to be future proof as it just runs on top of the Blockchains rather than being a blockchain itself. So, if a new blockchain technology comes out that is capable of 100,000 TPS then it can easily be integrated as Overledger just runs on top of it.
Likewise, with protocols such as HTTPS, SSH etc these will also emerge for blockchains such as ZK-Snarks and other privacy implementations as well as other features made available, all will be compatible with Overledger as its just sitting on top rather than forcing their own implementation for all.
It doesn’t require blockchains to fork their code to make it compatible, it doesn’t add the overhead of adding another blockchain with another consensus mechanism (most likely multiple as it has to go through many hops). All of this adds a lot of latency and restrictions which isn’t needed. The developer can just choose which blockchains they want to connect and use the consensus mechanisms of those blockchains rather than forced to use one.
Overledger can provide truly internet scale to meet whatever the demands may be, whether that be connecting multiple red belly blockchains together with 440,000 tps it doesn’t matter as it doesn’t add its consensus mechanism and uses proven internet scale technology such as that based on Kubernetes, which is where each task is split up into a self-contained container and each task is scaled out by deploying more to meet demand. Kubernetes is what runs Google Search engine where they scale up and down billions of containers every week.
Due to this being more of a summary, I strongly recommend you read this article which goes into detail about the different layers in Overledger.

https://preview.redd.it/1lpt98cixel31.png?width=1126&format=png&auto=webp&s=3928cf66cfe25bfce7dc84be7b6db670ac952ccf

But how does it provide the security of a blockchain if it doesn’t add its own blockchain?

This is often misunderstood by people. Overledger is not a blockchain however it still uses a blockchain for security, immutability, traceability etc, just rather than force people to use their own blockchain, it utilises the source and destination blockchains instead. The key thing to understand is the use of its patented technology TrustTag, which was made freely available to anyone with the Overledger SDK.
Please see this article which explains TrustTag in detail with examples showing how hashing / digital signatures work etc
A quick overview is if i want to send data from one blockchain to another the Overledger SDK using Trusttag will put the data through a hashing algorithm. The Hash is then included in digital signature as part of the transaction which is signed by the user’s private key and then validated through normal consensus and stored as metadata on the source blockchain. The message is then sent to the MAPP off chain. The MAPP periodically scans the blockchains and puts the received message through a hashing algorithm and compares the Hash to the one stored as metadata on the blockchain. This ensures that the message hasn’t been modified in transit, the message is encrypted and only the Hash is stored on chain so completely private, provides immutability as it was signed by the user’s private key which only they have and is stored on the blockchain for high availability and secure so that it can’t be modified, with the ability to refer back to it at any point in time.
Despite Overledger being a very secure platform, with the team having a very strong security background such as Gilbert who was chief security information officer for Vocalink (Bank of England) managing £6 trillion of payments every year and classified as national critical security (highest level you can get), ultimately you don’t need to trust Overledger. Transactions are signed and encrypted at client side, so Overledger has no way of being able to see the contents. It can’t modify any transaction as the digital signature which includes a hash of the transaction would be different so would get rejected. Transaction security isn’t reduced as it is signed at source using however many nodes the source blockchain has rather than a smaller amount of nodes with an interoperability blockchain in the middle.

Patents

The core code of Overledger is closed source and patented, one of the recent patents can be seen here, along with TrustTag and further ones are being filed. The Overledger SDK is open source and is available in Java and Javascript currently, with plans to support Pyhton and Ruby in the near future. Java and Javascript are the most popular programming languages used today.
The Blockchain connectors are also open source and this allows the community to create connectors to connect their favourite blockchain so that it can benefit from blockchain interoperability and making it available to all enterprises / developers currently utilising Overledger. Creating is currently taking around a week to implement and so far, have been added based upon client demand.

Multi Chain Applications (MAPPs)

Multi Chain Applications (MAPPs) enable an application to use multiple blockchains and interoperate between them. Treaty Contracts enable a developer to build a MAPP and then change the underlying blockchain it uses with just a quick change of couple of lines of code. This is vital for enterprises as it’s still early days in Blockchian and we don’t know which are going to be the best blockchain in the future. Overledger easily integrates into existing applications using the Overledger SDK by just adding 3 lines of code. They don’t need to completely rewrite the application like you do with the majority of other projects and all existing java / javascript apps on Windows / Mobile app stores / business applications etc can easily integrate with overledger with minimal changes in just 8 minutes.

Treaty Contracts

What Overledger will allow with Treaty contracts is to use popular programming languages such as Java and create a smart contract in Overledger that interacts with all of the connected blockchains. Even providing Smart contract functionality to blockchains that don’t support them such as Bitcoin. This means that developers don’t have to create all the smart contracts on each blockchain in all the different programming languages but instead just create them in Overledger using languages such as Java that are widely used today. If they need to use a different blockchain then it can be as easy as changing a line of code rather than having to completely rewrite the smart contracts.
Overledger isn’t a blockchain though, so how can it trusted with the smart contract? A Hash of the smart contract is published on any blockchain the MAPP developer requires and when called the smart contract is run its run through a hashing function to check that it matches the Hash value stored on the blockchain, ensuring that it has not been modified.
By running the Smart contract off chain this also increases Scalability enormously. With a blockchain all nodes have to run the smart contract one after another rather than in parallel. Not only do you get the performance benefit of not having to run the code against every single node but you can also run them in parallel to others executing smart contracts.
You can read more about Treaty Contracts here

The different versions of Overledger

Enterprise version

The current live version is the Enterprise version as that is where most of the adoption is taking place in blockchain due to permissioned blockchains being preferred until permissionless blockchains resolve the scalability, privacy and regulatory issues. Please see this article which goes into more details about Entereprise blockchain / adoption. The Enterprise version connects to permissioned blockchains as well as additional features / support suited for Enterprises.

Community version

The community version is due to be released later this year which will allow developers to benefit from creating MAPPs across permissionless blockchains. Developers can publish their MAPPs on the MAPP Store to create additional revenue streams for developers.

Where does Overledger run from? Is it Centralised?

Overledger can run from anywhere. The community version will have instances across multiple public clouds, Enterprises / developers may prefer to host the infrastructure themselves within a consortium which they can and are doing. For example SIA is the leading private Financial Network provider in Europe, it provides a dedicated high speed network which connects all the major banks, central banks, trading venues etc. SIA host Overledger within their private network so that all of those clients can access it in the confinement of their heavily regulated, secure, fast network. AUCloud / UKCLoud host Overledger in their environment to offer as a service to their clients which consist of Governments and critical national infrastructure.
For Blockchain nodes that interact with Overledger the choice is entirely up to the developer. Each member within a consortium may choose to host a node, some developers may prefer to use 3rd party hosting providers such as Infura, or Quant can also host them if they prefer, its entirely their choice.
Overledger allows for higher levels of decentralisation by storing the output across multiple blockchains so you not only benefit from the decentralisation of one blockchain but the combination of all of them. Ultimately though decentralisation is thrown around too much without many actually understanding what it means. It’s impossible to have complete decentralisation, when you sign a transaction to be added to a blockchain ultimately you still connect through a single ISP, connect through a single router, or the input into a transaction is done through a piece of software etc. What matters to be decentralised is where trust is involved. As i have mentioned before you don’t need to trust the OS, it’s just providing instructions on how to interact with the blockchains, the end user is signing the transactions / encrypting at client side. Nothing can be seen or modified with the OS. Even if somehow the transaction did get modified then it would get rejected when consensus is done as the hash / digital signature won’t match at the destination blockchain. Where the transaction actually gets put onto the blockchain is where decentralisation matters, because thats what needs to be trusted and conensus is reached and Overledger enables this to be written across multiple blockchains at the same time.

The Team

The team are very well connected with a wealth of experience at very senior roles at Global enterprises which I will include a few examples below. Gilbert Verdian the CEO was the Head of security for the payment infrastructure for the Bank of England through his CISO role with Vocalink (Mastercard)managing £6 trillion every year. This is treated by the government as critical national infrastructure which is the highest level of criticallity because its so fundamental to the security of the country. They have experience and know what it takes to run a secure financial infrastructure and meeting requirements of regulators. Gilbert was director for Cybersecurity at PWC, Security for HSBC and Ernst & Young as well as various government roles such as the CISO for the Australian NSW Health, Head of Security at the UK government for Ministry of Justice and HM Treasury in addition to being part of the committee for the European Commission, US Federal Reserve and the Bank of England.
Cecilia Harvey is the Chief Operating Officer, where she was previously a Director at HSBC in Global Banking and Markets and before that Director at Vocalink. Cecilia was also Chief Operating Officer at Citi for Markets and Securities Services Technology as well as working for Barclays, Accenture, IBM and Morgan Stanley.
Vijay Verma is the Overledger platform lead with over 15 years of developer experience in latest technologies like Java, Scala, Blockchain & enterprise technology solutions. Over the course of his career, he has worked for a number of prestigious organisations including J&J, Deutsche, HSBC, BNP Paribas, UBS Banks, HMRC and Network Rail.
Guy Dietrich, the managing director of Rockefeller Capital (manages $19 Billion in assets) has joined the board of Quant Network, and has recently personally attended meetings with the Financial Conduct Authority (FCA) with Gilbert

As well as advisors such as Paolo Tasca, the founder and Executive Director of the Centre for Blockchain Technologies (UCL CBT) at University College Londonfounder and executive director as well as Chris Adelsbach, Managing Director at Techstars, the worldwide network that helps entrepreneurs succeed. Techstars has partners such as Amazon, Barclays, Boeing, Ford, Google, Honda, IBM, Microsoft, PWC, Sony, Target, Total, Verizon, Western Union etc.
Due to client demand they are expanding to the US to setup a similar size office where board members such as Guy Dietrich will be extremely valuable in assisting with the expansion.

The most exciting part about the project though is just how much adoption there has been of the platform, from huge global enterprises, governments and cloud providers they are on track for a revenue of $10 million in their first year. I will go through these in the next article, followed by further article explaining how the Token and Treasury works.

JP Morgan transfer $6 Trillion every day, if they move that onto blockchain and need interoperability between two Permissioned blockchains that have to connect via a public Interoperability blockchain, then it would always have to be more costly to attack the blockchain than the value from stealing the funds transacted through the blockchain.
  • Imposes a lot of limitations on connected blockchains to fork their code which may mean they have to drop some existing functionality as well as prevent them from adding certain features in the future.
  • Creates a single point of failure — If the Interoperability blockchain or connector has an issue then this affects each connected blockchain.
  • It doesn’t scale and acts as a bottleneck. Not only does building complex custom connectors not scale but the Interoperability blockchain that they are forcing all transactions to go through has to be faster than the combined throughput of connected blockchains. These Interoperability blockchains have limited tps, with the most being around 200 and is a trade off between performance and decentralisation.

But some Interoperability blockchains say they are infinitely scalable?

If the interoperability blockchain is limited to say 200 tps then the idea is to just have multiple instances of the blockchain and run them in parallel, so you benefit from the aggregated tps, but just how feasible is that? Lets say you want to connect Corda (capable of 2000+ tps) to Hyperledger (capable of up to 20,000 tps with recent upgrade). (Permissioned blockchains such as Hyperledger and Corda aren’t one big blockchain like say Bitcoin or Ethereum, they have separate instances for each consortium and each is capable of those speeds). So even when you have just 1 DAPP from one consortium that wants to connect Corda to Hyperledger and use 2000 tps for their DAPP, you would need 100 instances of the Interoperability blockchain, each with their own validators (which maybe 100–200 nodes each). So, 1 DAPP would need to cover the costs for 100 instances of the blockchain and running costs for 10,000 nodes…This is just one DAPP connected to one instance of a two permissioned blockchains, which are still in the early stages. Other blockchains such as Red Belly Blockchain can achieve 440,000 tps, and this will surely increase as the technology matures. There is also the added complexity of then aggregating the results / co-coordinating between the different instances of the blockchain. Then there are the environmental concerns, the power required for all of these instances / nodes is not sustainable.

It’s not just transactions per second of the blockchain as well, its the latency of all these added consensuses along the path to reach to the destination and not knowing whether the security of each of the hops is sufficient and can be trusted. To see examples of how this potential issue as well as others effect Cosmos you can see my article here. I recommend also reading a blog done by the CEO of Quant, Gilbert Verdian, which explains how Overledger differs here as well as detailed in the whitepaper here.

Overledger’s approach

In 1973 Vint Cerf invented the protocol that rules them all: TCP/IP. Most people have never heard of it. But it describes the fundamental architecture of the internet, and it made possible Wi-Fi, Ethernet, LANs, the World Wide Web, e-mail, FTP, 3G/4G — as well as all of the inventions built upon those inventions.
***Wired: So from the beginning, people, including yourself, had a vision of where the internet was going to go. Are you surprised, though, that at this point the IP protocol seems to beat almost anything it comes up against?***Cerf: I’m not surprised at all because we designed it to do that.This was very conscious. Something we did right at the very beginning, when we were writing the specifications, we wanted to make this a future-proof protocol. And so the tactic that we used to achieve that was to say that the protocol did not know how — the packets of the internet protocol layer didn’t know how they were being carried. And they didn’t care whether it was a satellite link or mobile radio link or an optical fiber or something else.We were very, very careful to isolate that protocol layer from any detailed knowledge of how it was being carried. Plainly, the software had to know how to inject it into a radio link, or inject it into an optical fiber, or inject it into a satellite connection. But the basic protocol didn’t know how that worked.And the other thing that we did was to make sure that the network didn’t know what the packets had in them. We didn’t encrypt them to prevent it from knowing — we just didn’t make it have to know anything. It’s just a bag of bits as far as the net was concerned.We were very successful in these two design features, because every time a new kind of communications technology came along, like frame relay or asynchronous transfer mode or passive optical networking or mobile radio‚ all of these different ways of communicating could carry internet packets.We would hear people saying, ‘The internet will be replaced by X25,’ or ‘The internet will be replaced by frame relay,’ or ‘The internet will be replaced by APM,’ or ‘The internet will be replaced by add-and-drop multiplexers.’Of course, the answer is, ‘No, it won’t.’ It just runs on top of everything. And that was by design. I’m actually very proud of the fact that we thought of that and carefully designed that capability into the system.
This is the approach Quant have taken with their Blockchain OS, Overledger to solve Blockchain interoperability. Compared to other Interoperability platforms that are trying to achieve interoperability at the transaction layer by connecting two blockchains via another blockchain, these will be ultimately be made redundant once faster methods are released. Overledger is designed to be future proof by isolating the layers so it doesn’t matter whether it’s a permissioned blockchain, permissionless, DAG, Legacy network, POW, POS etc because it abstracts the transaction layer from the messaging layer and runs on top of blockchains. Just as the Internet wasn’t replaced by X25, frame relay, APM etc, Overledger is designed to be future proof as it just runs on top of the Blockchains rather than being a blockchain itself. So, if a new blockchain technology comes out that is capable of 100,000 TPS then it can easily be integrated as Overledger just runs on top of it.
Likewise, with protocols such as HTTPS, SSH etc these will also emerge for blockchains such as ZK-Snarks and other privacy implementations as well as other features made available, all will be compatible with Overledger as its just sitting on top rather than forcing their own implementation for all.
It doesn’t require blockchains to fork their code to make it compatible, it doesn’t add the overhead of adding another blockchain with another consensus mechanism (most likely multiple as it has to go through many hops). All of this adds a lot of latency and restrictions which isn’t needed. The developer can just choose which blockchains they want to connect and use the consensus mechanisms of those blockchains rather than forced to use one.
Overledger can provide truly internet scale to meet whatever the demands may be, whether that be connecting multiple red belly blockchains together with 440,000 tps it doesn’t matter as it doesn’t add its consensus mechanism and uses proven internet scale technology such as that based on Kubernetes, which is where each task is split up into a self-contained container and each task is scaled out by deploying more to meet demand. Kubernetes is what runs Google Search engine where they scale up and down billions of containers every week.
Due to this being more of a summary, I strongly recommend you read this article which goes into detail about the different layers in Overledger.

https://preview.redd.it/6x7tjq9jwel31.png?width=1126&format=png&auto=webp&s=52ac5b9ebb45908ef6070d2eed6d107d380da1df

But how does it provide the security of a blockchain if it doesn’t add its own blockchain?

This is often misunderstood by people. Overledger is not a blockchain however it still uses a blockchain for security, immutability, traceability etc, just rather than force people to use their own blockchain, it utilises the source and destination blockchains instead. The key thing to understand is the use of its patented technology TrustTag, which was made freely available to anyone with the Overledger SDK.
Please see this article which explains TrustTag in detail with examples showing how hashing / digital signatures work etc
A quick overview is if i want to send data from one blockchain to another the Overledger SDK using Trusttag will put the data through a hashing algorithm. The Hash is then included in digital signature as part of the transaction which is signed by the user’s private key and then validated through normal consensus and stored as metadata on the source blockchain. The message is then sent to the MAPP off chain. The MAPP periodically scans the blockchains and puts the received message through a hashing algorithm and compares the Hash to the one stored as metadata on the blockchain. This ensures that the message hasn’t been modified in transit, the message is encrypted and only the Hash is stored on chain so completely private, provides immutability as it was signed by the user’s private key which only they have and is stored on the blockchain for high availability and secure so that it can’t be modified, with the ability to refer back to it at any point in time.
Despite Overledger being a very secure platform, with the team having a very strong security background such as Gilbert who was chief security information officer for Vocalink (Bank of England) managing £6 trillion of payments every year and classified as national critical security (highest level you can get), ultimately you don’t need to trust Overledger. Transactions are signed and encrypted at client side, so Overledger has no way of being able to see the contents. It can’t modify any transaction as the digital signature which includes a hash of the transaction would be different so would get rejected. Transaction security isn’t reduced as it is signed at source using however many nodes the source blockchain has rather than a smaller amount of nodes with an interoperability blockchain in the middle.

Patents

The core code of Overledger is closed source and patented, one of the recent patents can be seen here, along with TrustTag and further ones are being filed. The Overledger SDK is open source and is available in Java and Javascript currently, with plans to support Pyhton and Ruby in the near future. Java and Javascript are the most popular programming languages used today.
The Blockchain connectors are also open source and this allows the community to create connectors to connect their favourite blockchain so that it can benefit from blockchain interoperability and making it available to all enterprises / developers currently utilising Overledger. Creating is currently taking around a week to implement and so far, have been added based upon client demand.

Multi Chain Applications (MAPPs)

Multi Chain Applications (MAPPs) enable an application to use multiple blockchains and interoperate between them. Treaty Contracts enable a developer to build a MAPP and then change the underlying blockchain it uses with just a quick change of couple of lines of code. This is vital for enterprises as it’s still early days in Blockchian and we don’t know which are going to be the best blockchain in the future. Overledger easily integrates into existing applications using the Overledger SDK by just adding 3 lines of code. They don’t need to completely rewrite the application like you do with the majority of other projects and all existing java / javascript apps on Windows / Mobile app stores / business applications etc can easily integrate with overledger with minimal changes in just 8 minutes.

Treaty Contracts

What Overledger will allow with Treaty contracts is to use popular programming languages such as Java and create a smart contract in Overledger that interacts with all of the connected blockchains. Even providing Smart contract functionality to blockchains that don’t support them such as Bitcoin. This means that developers don’t have to create all the smart contracts on each blockchain in all the different programming languages but instead just create them in Overledger using languages such as Java that are widely used today. If they need to use a different blockchain then it can be as easy as changing a line of code rather than having to completely rewrite the smart contracts.
Overledger isn’t a blockchain though, so how can it trusted with the smart contract? A Hash of the smart contract is published on any blockchain the MAPP developer requires and when called the smart contract is run its run through a hashing function to check that it matches the Hash value stored on the blockchain, ensuring that it has not been modified.
By running the Smart contract off chain this also increases Scalability enormously. With a blockchain all nodes have to run the smart contract one after another rather than in parallel. Not only do you get the performance benefit of not having to run the code against every single node but you can also run them in parallel to others executing smart contracts.
You can read more about Treaty Contracts here

The different versions of Overledger

Enterprise version

The current live version is the Enterprise version as that is where most of the adoption is taking place in blockchain due to permissioned blockchains being preferred until permissionless blockchains resolve the scalability, privacy and regulatory issues. Please see this article which goes into more details about Entereprise blockchain / adoption. The Enterprise version connects to permissioned blockchains as well as additional features / support suited for Enterprises.

Community version

The community version is due to be released later this year which will allow developers to benefit from creating MAPPs across permissionless blockchains. Developers can publish their MAPPs on the MAPP Store to create additional revenue streams for developers.

Where does Overledger run from? Is it Centralised?

Overledger can run from anywhere. The community version will have instances across multiple public clouds, Enterprises / developers may prefer to host the infrastructure themselves within a consortium which they can and are doing. For example SIA is the leading private Financial Network provider in Europe, it provides a dedicated high speed network which connects all the major banks, central banks, trading venues etc. SIA host Overledger within their private network so that all of those clients can access it in the confinement of their heavily regulated, secure, fast network. AUCloud / UKCLoud host Overledger in their environment to offer as a service to their clients which consist of Governments and critical national infrastructure.
For Blockchain nodes that interact with Overledger the choice is entirely up to the developer. Each member within a consortium may choose to host a node, some developers may prefer to use 3rd party hosting providers such as Infura, or Quant can also host them if they prefer, its entirely their choice.
Overledger allows for higher levels of decentralisation by storing the output across multiple blockchains so you not only benefit from the decentralisation of one blockchain but the combination of all of them. Ultimately though decentralisation is thrown around too much without many actually understanding what it means. It’s impossible to have complete decentralisation, when you sign a transaction to be added to a blockchain ultimately you still connect through a single ISP, connect through a single router, or the input into a transaction is done through a piece of software etc. What matters to be decentralised is where trust is involved. As i have mentioned before you don’t need to trust the OS, it’s just providing instructions on how to interact with the blockchains, the end user is signing the transactions / encrypting at client side. Nothing can be seen or modified with the OS. Even if somehow the transaction did get modified then it would get rejected when consensus is done as the hash / digital signature won’t match at the destination blockchain. Where the transaction actually gets put onto the blockchain is where decentralisation matters, because thats what needs to be trusted and conensus is reached and Overledger enables this to be written across multiple blockchains at the same time.

The Team

The team are very well connected with a wealth of experience at very senior roles at Global enterprises which I will include a few examples below. Gilbert Verdian the CEO was the Head of security for the payment infrastructure for the Bank of England through his CISO role with Vocalink (Mastercard)managing £6 trillion every year. This is treated by the government as critical national infrastructure which is the highest level of criticallity because its so fundamental to the security of the country. They have experience and know what it takes to run a secure financial infrastructure and meeting requirements of regulators. Gilbert was director for Cybersecurity at PWC, Security for HSBC and Ernst & Young as well as various government roles such as the CISO for the Australian NSW Health, Head of Security at the UK government for Ministry of Justice and HM Treasury in addition to being part of the committee for the European Commission, US Federal Reserve and the Bank of England.
Cecilia Harvey is the Chief Operating Officer, where she was previously a Director at HSBC in Global Banking and Markets and before that Director at Vocalink. Cecilia was also Chief Operating Officer at Citi for Markets and Securities Services Technology as well as working for Barclays, Accenture, IBM and Morgan Stanley.
Vijay Verma is the Overledger platform lead with over 15 years of developer experience in latest technologies like Java, Scala, Blockchain & enterprise technology solutions. Over the course of his career, he has worked for a number of prestigious organisations including J&J, Deutsche, HSBC, BNP Paribas, UBS Banks, HMRC and Network Rail.
Guy Dietrich, the managing director of Rockefeller Capital (manages $19 Billion in assets) has joined the board of Quant Network, and has recently personally attended meetings with the Financial Conduct Authority (FCA) with Gilbert

As well as advisors such as Paolo Tasca, the founder and Executive Director of the Centre for Blockchain Technologies (UCL CBT) at University College Londonfounder and executive director as well as Chris Adelsbach, Managing Director at Techstars, the worldwide network that helps entrepreneurs succeed. Techstars has partners such as Amazon, Barclays, Boeing, Ford, Google, Honda, IBM, Microsoft, PWC, Sony, Target, Total, Verizon, Western Union etc.
Due to client demand they are expanding to the US to setup a similar size office where board members such as Guy Dietrich will be extremely valuable in assisting with the expansion.

The most exciting part about the project though is just how much adoption there has been of the platform, from huge global enterprises, governments and cloud providers they are on track for a revenue of $10 million in their first year. I will go through these in the next article, followed by further article explaining how the Token and Treasury works.

What is Quant Networks Blockchain Operating System, Overledger? And why are Enterprises adopting it at mass scale?

Won't let me post the related images here, but please refer to this article which includes them https://medium.com/@CryptoSeq/what-is-a-blockchain-operating-system-and-what-are-the-benefits-c561d8275de6
Overledger is the world’s first blockchain operating system (OS) that not only inter-connects blockchains but also existing enterprise platforms, applications and networks to blockchain and facilitates the creation of internet scale multi-chain applications otherwise known as mApps.
In less than 10 months since launching Overledger they have provided interoperability with the full range of DLT technologies from all the leading Enterprise Permissioned blockchains such as Hyperledger, R3’s Corda, JP Morgan’s Quorum, permissioned variants of Ethereum and Ripple (XRPL) as well as the leading Public Permissionless blockchains / DAGs such as Bitcoin, Stellar, Ethereum, IOTA and EOS as well as the most recent blockchain to get added Binance Chain. In addition, Overledger also connects to Existing Networks / Off Chain / Oracle functionality and it does all of this in a way that is hugely scalable, without imposing restrictions / requiring blockchains to fork their code and can easily integrate into existing applications / networks by just adding 3 lines of code.

What is a blockchain Operating system?

You will be familiar with Operating systems such as Microsoft Windows, Apple Mac OS, Google’s Android etc but these are all Hardware based Operating Systems. Hardware based Operating Systems provide a platform to build and use applications that abstracts all of the complexities involved with integrating with all the hardware resources such as CPU, Memory, Storage, Mouse, Keyboard, Video etc so software can easily integrate with it. It provides interoperability between the Hardware devices and Software.
Overledger is a Blockchain Operating System, it provides a platform to build and use applications that abstracts all of the complexities involved with integrating with all the different blockchains, different OP_Codes being used, messaging formats etc as well as connecting to existing non-blockchain networks. It provides interoperability between Blockchains, Existing Networks and Software / MAPPs

How is Overledger different to other interoperability projects?

Other projects are trying to achieve interoperability by adding another blockchain on top of existing blockchains. This adds a lot of overhead, complexity, and technical risk. There are a few variants but essentially they either need to create custom connectors for each connected blockchain and / or require connected chains to fork their code to enable interoperability. An example of the process can be seen below:
User sends transaction to a multi sig contract on Blockchain A, wait for consensus to be reached on Blockchain A
A custom connector consisting of Off Chain Relay Nodes are monitoring transactions sent to the smart contract on Blockchain A. Once they see the transaction, they then sign a transaction on the Interoperability blockchain as proof the event has happened on Blockchain A.
Wait for consensus to be reached on the Interoperability Blockchain.
The DAPP running on the Interoperability Blockchain is then updated with the info about the transaction occurring on Blockchain A and then signs a transaction on the Interoperability blockchain to a multi sig contract on the Interoperability Blockchain.
Wait for consensus to be reached on the interoperability Blockchain.
A different custom connector consisting of Off Chain Relay Nodes are monitoring transactions sent to the Smart Contract on the Interoperability Blockchain which are destined for Blockchain B. Once they see the transaction, they sign a transaction on Blockchain B. Wait for consensus to be reached on Blockchain B.

Other solutions require every connecting blockchain to fork their code and implement their Interoperability protocol. This means the same type of connector can be used instead of a custom one for every blockchain however every connected blockchain has to fork their code to implement the protocol. This enforces a lot of restrictions on what the connected blockchains can implement going forward.
Some problems with these methods:

But some Interoperability blockchains say they are infinitely scalable?

If the interoperability blockchain is limited to say 200 tps then the idea is to just have multiple instances of the blockchain and run them in parallel, so you benefit from the aggregated tps, but just how feasible is that? Lets say you want to connect Corda (capable of 2000+ tps) to Hyperledger (capable of up to 20,000 tps with recent upgrade). (Permissioned blockchains such as Hyperledger and Corda aren’t one big blockchain like say Bitcoin or Ethereum, they have separate instances for each consortium and each is capable of those speeds). So even when you have just 1 DAPP from one consortium that wants to connect Corda to Hyperledger and use 2000 tps for their DAPP, you would need 100 instances of the Interoperability blockchain, each with their own validators (which maybe 100–200 nodes each). So, 1 DAPP would need to cover the costs for 100 instances of the blockchain and running costs for 10,000 nodes…This is just one DAPP connected to one instance of a two permissioned blockchains, which are still in the early stages.

There is also the added complexity of then aggregating the results / co-coordinating between the different instances of the blockchain. Then there are the environmental concerns, the power required for all of these instances / nodes is not sustainable.
It’s not just transactions per second of the blockchain as well, its the latency of all these added consensuses along the path to reach to the destination and not knowing whether the security of each of the hops is sufficient and can be trusted. To see examples of how this potential issue as well as others effect Cosmos you can see my article here.

Overledger’s approach

In 1973 Vint Cerf invented the protocol that rules them all: TCP/IP. Most people have never heard of it. But it describes the fundamental architecture of the internet, and it made possible Wi-Fi, Ethernet, LANs, the World Wide Web, e-mail, FTP, 3G/4G — as well as all of the inventions built upon those inventions.
Wired: So from the beginning, people, including yourself, had a vision of where the internet was going to go. Are you surprised, though, that at this point the IP protocol seems to beat almost anything it comes up against? Cerf: I’m not surprised at all because we designed it to do that. This was very conscious. Something we did right at the very beginning, when we were writing the specifications, we wanted to make this a future-proof protocol. And so the tactic that we used to achieve that was to say that the protocol did not know how — the packets of the internet protocol layer didn’t know how they were being carried.

And that was by design. I’m actually very proud of the fact that we thought of that and carefully designed that capability into the system.
This is the approach Quant have taken with their Blockchain OS, Overledger to solve Blockchain interoperability. Compared to other Interoperability platforms that are trying to achieve interoperability at the transaction layer by connecting two blockchains via another blockchain, these will be ultimately be made redundant once faster methods are released. Overledger is designed to be future proof by isolating the layers so it doesn’t matter whether it’s a permissioned blockchain, permissionless, DAG, Legacy network, POW, POS etc because it abstracts the transaction layer from the messaging layer and runs on top of blockchains. Just as the Internet wasn’t replaced by X25, frame relay, APM etc, Overledger is designed to be future proof as it just runs on top of the Blockchains rather than being a blockchain itself. So, if a new blockchain technology comes out that is capable of 100,000 TPS then it can easily be integrated as Overledger just runs on top of it.
Likewise, with protocols such as HTTPS, SSH etc these will also emerge for blockchains such as ZK-Snarks and other privacy implementations as well as other features made available, all will be compatible with Overledger as its just sitting on top rather than forcing their own implementation for all.
It doesn’t require blockchains to fork their code to make it compatible, it doesn’t add the overhead of adding another blockchain with another consensus mechanism (most likely multiple as it has to go through many hops). All of this adds a lot of latency and restrictions which isn’t needed. The developer can just choose which blockchains they want to connect and use the consensus mechanisms of those blockchains rather than forced to use one.
Overledger can provide truly internet scale to meet whatever the demands may be, whether that be connecting multiple red belly blockchains together with 440,000 tps it doesn’t matter as it doesn’t add its consensus mechanism and uses proven internet scale technology such as that based on Kubernetes, which is where each task is split up into a self-contained container and each task is scaled out by deploying more to meet demand. Kubernetes is what runs Google Search engine where they scale up and down billions of containers every week.
Due to this being more of a summary, I strongly recommend you read this article which goes into detail about the different layers in Overledger.

But how does it provide the security of a blockchain if it doesn’t add its own blockchain?

This is often misunderstood by people. Overledger is not a blockchain however it still uses a blockchain for security, immutability, traceability etc, just rather than force people to use their own blockchain, it utilises the source and destination blockchains instead. The key thing to understand is the use of its patented technology TrustTag, which was made freely available to anyone with the Overledger SDK.

A quick overview is if i want to send data from one blockchain to another the Overledger SDK using Trusttag will put the data through a hashing algorithm. The Hash is then included in digital signature as part of the transaction which is signed by the user’s private key and then validated through normal consensus and stored as metadata on the source blockchain. The message is then sent to the MAPP off chain. The MAPP periodically scans the blockchains and puts the received message through a hashing algorithm and compares the Hash to the one stored as metadata on the blockchain.

Transaction security isn’t reduced as it is signed at source using however many nodes the source blockchain has rather than a smaller amount of nodes with an interoperability blockchain in the middle.

Creating is currently taking around a week to implement and so far, have been added based upon client demand.

Multi Chain Applications (MAPPs)

Multi Chain Applications (MAPPs) enable an application to use multiple blockchains and interoperate between them. Treaty Contracts enable a developer to build a MAPP and then change the underlying blockchain it uses with just a quick change of couple of lines of code. This is vital for enterprises as it’s still early days in Blockchian and we don’t know which are going to be the best blockchain in the future. Overledger easily integrates into existing applications using the Overledger SDK by just adding 3 lines of code. They don’t need to completely rewrite the application like you do with the majority of other projects and all existing java / javascript apps on Windows / Mobile app stores / business applications etc can easily integrate with overledger with minimal changes in just 8 minutes.

Treaty Contracts

What Overledger will allow with Treaty contracts is to use popular programming languages such as Java and create a smart contract in Overledger that interacts with all of the connected blockchains. Even providing Smart contract functionality to blockchains that don’t support them such as Bitcoin. This means that developers don’t have to create all the smart contracts on each blockchain in all the different programming languages but instead just create them in Overledger using languages such as Java that are widely used today. If they need to use a different blockchain then it can be as easy as changing a line of code rather than having to completely rewrite the smart contracts.
Overledger isn’t a blockchain though, so how can it trusted with the smart contract? A Hash of the smart contract is published on any blockchain the MAPP developer requires and when called the smart contract is run its run through a hashing function to check that it matches the Hash value stored on the blockchain, ensuring that it has not been modified.
By running the Smart contract off chain this also increases Scalability enormously. With a blockchain all nodes have to run the smart contract one after another rather than in parallel. Not only do you get the performance benefit of not having to run the code against every single node but you can also run them in parallel to others executing smart contracts.

The different versions of Overledger

Enterprise version

The current live version is the Enterprise version as that is where most of the adoption is taking place in blockchain due to permissioned blockchains being preferred until permissionless blockchains resolve the scalability, privacy and regulatory issues. Please see this article which goes into more details about Entereprise blockchain / adoption. The Enterprise version connects to permissioned blockchains as well as additional features / support suited for Enterprises.

Community version

The community version is due to be released later this year which will allow developers to benefit from creating MAPPs across permissionless blockchains. Developers can publish their MAPPs on the MAPP Store to create additional revenue streams for developers.

Where does Overledger run from? Is it Centralised?

Overledger can run from anywhere. The community version will have instances across multiple public clouds, Enterprises / developers may prefer to host the infrastructure themselves within a consortium which they can and are doing. For example SIA is the leading private Financial Network provider in Europe, it provides a dedicated high speed network which connects all the major banks, central banks, trading venues etc. SIA host Overledger within their private network so that all of those clients can access it in the confinement of their heavily regulated, secure, fast network. AUCloud / UKCLoud host Overledger in their environment to offer as a service to their clients which consist of Governments and critical national infrastructure.
For Blockchain nodes that interact with Overledger the choice is entirely up to the developer. Each member within a consortium may choose to host a node, some developers may prefer to use 3rd party hosting providers such as Infura, or Quant can also host them if they prefer, its entirely their choice.
Overledger allows for higher levels of decentralisation by storing the output across multiple blockchains so you not only benefit from the decentralisation of one blockchain but the combination of all of them. Ultimately though decentralisation is thrown around too much without many actually understanding what it means. It’s impossible to have complete decentralisation, when you sign a transaction to be added to a blockchain ultimately you still connect through a single ISP, connect through a single router, or the input into a transaction is done through a piece of software etc. What matters to be decentralised is where trust is involved. As i have mentioned before you don’t need to trust the OS, it’s just providing instructions on how to interact with the blockchains, the end user is signing the transactions / encrypting at client side. Nothing can be seen or modified with the OS. Even if somehow the transaction did get modified then it would get rejected when consensus is done as the hash / digital signature won’t match at the destination blockchain. Where the transaction actually gets put onto the blockchain is where decentralisation matters, because thats what needs to be trusted and conensus is reached and Overledger enables this to be written across multiple blockchains at the same time.

The Team

The team are very well connected with a wealth of experience at very senior roles at Global enterprises which I will include a few examples below. Gilbert Verdian the CEO was the Head of security for the payment infrastructure for the Bank of England through his CISO role with Vocalink (Mastercard)managing £6 trillion every year. This is treated by the government as critical national infrastructure which is the highest level of criticallity because its so fundamental to the security of the country. They have experience and know what it takes to run a secure financial infrastructure and meeting requirements of regulators. Gilbert was director for Cybersecurity at PWC, Security for HSBC and Ernst & Young as well as various government roles such as the CISO for the Australian NSW Health, Head of Security at the UK government for Ministry of Justice and HM Treasury in addition to being part of the committee for the European Commission, US Federal Reserve and the Bank of England.
Cecilia Harvey is the Chief Operating Officer, where she was previously a Director at HSBC in Global Banking and Markets and before that Director at Vocalink. Cecilia was also Chief Operating Officer at Citi for Markets and Securities Services Technology as well as working for Barclays, Accenture, IBM and Morgan Stanley.
Vijay Verma is the Overledger platform lead with over 15 years of developer experience in latest technologies like Java, Scala, Blockchain & enterprise technology solutions. Over the course of his career, he has worked for a number of prestigious organisations including J&J, Deutsche, HSBC, BNP Paribas, UBS Banks, HMRC and Network Rail.
Guy Dietrich, the managing director of Rockefeller Capital (manages $19 Billion in assets) has joined the board of Quant Network, and has recently personally attended meetings with the Financial Conduct Authority (FCA) with Gilbert
https://twitter.com/gverdian/status/1168628166644183042
As well as advisors such as Paolo Tasca, the founder and Executive Director of the Centre for Blockchain Technologies (UCL CBT) at University College Londonfounder and executive director as well as Chris Adelsbach, Managing Director at Techstars, the worldwide network that helps entrepreneurs succeed. Techstars has partners such as Amazon, Barclays, Boeing, Ford, Google, Honda, IBM, Microsoft, PWC, Sony, Target, Total, Verizon, Western Union etc.
Due to client demand they are expanding to the US to setup a similar size office where board members such as Guy Dietrich will be extremely valuable in assisting with the expansion.
The most exciting part about the project though is just how much adoption there has been of the platform, from huge global enterprises, governments and cloud providers they are on track for a revenue of $10 million in their first year. I will go through these in the next article, followed by further article explaining how the Token and Treasury works.
