Fanboyism, maximalism, interoperabilty, working with others and division of time transcript

Hi everybody, this is Charles Hoskinson broadcasting live from warm sunny Colorado.
I wanted to make a video about division of time. I've been recently making a lot of commentary on the ETC ecosystem. I've also reached out to other ecosystems like the Bitcoin Cash ecosystem, the Litecoin ecosystem for a variety of reasons and I noticed that there are some people in the comments and then telegram and twitter and other places say "oh no" focus 100% of your effort on Cardano! Why are you talking to ETC, why are you doing this and doing that?
So first off I run a big company. I we have over 250 people. About half of those people wake up every day and they're involved in Cardano. The other half are not so. As the CEO of a company where you have that kind of division there's non-Cardano things I do. Cardano's our largest project, we're heavily involved in it and obviously we wake up every day and we want Cardano to be successful and have billions of users and this is why we are following the process we're following. We're building the technology we're building. It's why we work very hard trying to commercialize it.
Every deal we do in Africa, every deal we do in eastern Europe, every deal we do in Asia, we have a Cardano first policy of deploying those deals on that platform and we built that platform to service those deals and as that platform evolves you'll see more use and utility from our sales channels in that respect. That said, one of the pillars of a third generation cryptocurrency is interoperability. It's kind of a silly thing to be a maximalist but then also talk about interoperability. What the hell is the point that? Either you want one chain to rule them all and therefore you don't care at all about talking to other systems or you put your money where your mouth is and you work on those other systems. You build expertise in those systems, you affect changes in those systems so that those systems can partner with our systems and work with our systems.
You know the Samsung CEO? He has a division that every day gets up and works with Apple and they work on the motherboards of the iPhone and build memory for them. Do all kinds of cool things and Samsung's division knows what the iPhone is going to look like before any of us knows. At the same time, there's another division at Samsung that wakes up every day and works on phones like the Galaxy to compete with the iPhone. Great companies have the capacity to do these things and we are a great company in that respect we have different and dedicated teams for different products and projects.
Now, we will never work on overlapping systems. It's not the case that we're going to have developers go and work on Cardano and something that's a direct competitor of Cardano because it makes no competitive sense for that to happen and I do not view ETC as a competitor of Cardano. It's a proof-of-work system, not a proof-of-stake system. It's a code-is-law system, not a world-financial operating system. It's a system that will always have a smaller group of people in it and always have a smaller set of things to do so time spent there with a completely separate team has no bearing or impact on our ability to deliver things with Cardano.
I can't accelerate things above and beyond what the teams can do, for example, today. I'm waiting for Daedalus flight to come out. There is nothing I can do. I can't pick up the phone and call the engineers and say can you ship it 15 minutes faster. The plan, it's been set, the release manager is there, the QA, team's there, everybody knows what to do. There's consensus amongst that team. They're going off to the mountain top, get it done and when it's done they'll let me know and then I'll tweet "new Daedalus is out guys" go play with it and it gives me some work to do of course but until they finish their job there's nothing to do in that respect. The Cardano plans we have are well set , we know exactly what we need to do. Those teams are working hard and I do everything in my power to accelerate things where and when it's safe to do so and everything in my power to get things done.
Shelley, for example. We worked so hard to get that out on July 29th, we had almost unlimited overtime. Everyone worked the weekend. Some people worked over 40 days straight to get that release done. Meanwhile half of the company was doing other things in other capacities and working on those projects. None of their work or the other cryptocurrencies we tend to work with had any bearing or impact on our ability to accelerate or decelerate the Shelley work stream. I just want to make sure everybody understands that and for people who have developed a maximalist mindset to get out of that maximalist mindset. There's a place for maximalism, it's called Bitcoin maximalism. If you live there, go there, okay and go believe in that project, in that chain but this is the Cardano ecosystem. It's going to literally work with hundreds if not thousands of different standards over its life. From central banks to other cryptocurrencies to legacy financial operators from the Chases of the world to the Goldman Sachs' of the world.
Provisions will be made to build special hooks for these systems including interoperability with permission systems. It's very likely in the next 24 months Cardano will be talking to an instance of Hyperledger Fabric from IBM. Very likely that that's going to happen. It's very likely that we'll consult on a project that does that and no way does this diminish the road map or somehow make Cardano less competitive. It's actually quite the opposite. The fact that we can work with those systems, the fact that we can do things with those systems means that the platform as a whole is intrinsically more valuable. It's easier to sell to Fortune 500 companies. It's easier to get use utility and adoption because people understand that they're not being led down the road of vendor lock-in and regressing back to the old days of internet explorer or what ConsenSys is trying to do with Ethereum, trying to lock everybody into one standard, one system, rather the value proposition we offer.
Is true interoperability the ability to move in and out? Furthermore, when you create partnerships with other ecosystems then their success is our success. For example, if the treasury system proposal succeeds in ETC they will be in the market for a permanent treasury system in 2021. We as a community can make the case that we've constructed with Voltaire is a great choice for them and of course we'll try to make that case and if it's successful we provide mutual value and benefit more volume and transactions and activity on the Cardano network, and for ETC they have a best-in-class treasury system that meets the values of that community. The exact same argument can be made for Litecoin, or for Bitcoin cash or for other systems and if you want to see the wrapped Litecoin video that I did earlier in the year it gives a great road map for a potential push there.
Furthermore, what if we turn Daedalus into a multi-currency wallet? That's already going to happen because we have a multi-asset standard and so when people issue tokens on Cardano Daedalus will support those tokens sometime in the future. It would be very easy for us to pull Ethereum classic and Litecoin and Bitcoin cash and other ecosystems into the Daedalus wallet. What does that mean? It means that people who live in that ecosystem will be using our technology as their day-to-day experience in hosting for their token! What does that mean if we have a DEX built into that thing? It potentially could create more adoption in use and utility for ada and this is the point we accomplish so much more working together than beating each other down.
I am damn tired of the cryptocurrency markets as they are. The fanboys, the trolls, the FUD, the maximalism, the relentless allegations that people you disagree with or hold different tokens are scammers or criminals or bad human beings. It's time we as an industry set this aside and grow up. Just grow up or else what's the point? Why would anybody looking from the outside at all of this chaos and noise and insanity and maximalism want to come play in this pool? It's like you're about to enter a bar and you see a bar fight. Do you keep going in or you turn around and walk away and say I don't want that trouble. I'm going to go down the street somewhere else that's safer and so how will we ever get mainstream adoption, how will we ever make the argument to governments that they should trust their elections, their property, perhaps even the money of their people on our systems if we're incapable of entertaining other ideas, other philosophies and other ecosystems? We don't deserve the right for that responsibility if we're not mature enough to have differences of opinion and be able to welcome other ecosystems into our own.
So this video is a call against maximalism first and foremost and second it's a realization that the duties of an executive officer are extensive meaning that there are days I wake up and there are Ethereum days and, by the way, working in that ecosystem gives me and my company exhaustive knowledge on how Ethereum works which allows me then to build a better product than they have and understand where all the bodies are buried: all the flaws in the protocols, the security issues, the performance issues, the smart contract development experience. That intimacy is extremely important to be able to predict, react and also plan a competitive strategy that can take you in a different and better direction.
You just don't live in a mono-culture. It's a bad deal, that's the second point. You have many projects. When you have a larger company, some of those projects are completely separate from each other. Some of those projects may have a bit of overlap. We have a philosophy that we don't work on competing products. For example we have done work with horizon (Horizon2020?) and as a consequence of doing work with them we're probably not going to work on zcash at the same time. As long as we have that relationship there we, for example, work on Cardano so we're not going to go work on another proof-of-stake system that wants to be a financial operating system. That would be a direct competitor. For example, Tezos would be happy to jointly author papers and coordinate collaboration but there needs to be a Cardano benefit in that relationship whereas ETC as I've mentioned is a totally different system and it's something that we have as a company historically worked on for years.
We started our participation in 2016. We built a full client in that process. Did that have any impact on our ability to deliver Cardano? We had a completely separate engineering team. That team was actually sourced from external companies. Scalac and Atix Labs to begin with and then we built on top of it and it had different product and project management and it was completely written with a different group. So it might as well have been a different company for that matter and I just talked to the team but the Cardano team was doing its own thing so I I think we need to just cut it out. Cut out the maximalism, cut out this idea that there is only one truth. We live in a nuanced world and we live in a world of interoperability. We have to embrace that if we wish to be successful and let us be the adults in the room. Let's be the place where this isn't the bar fight and let's be the place that welcomes everybody.
Furthermore, I've noticed some criticism from my own community. When people criticize us and they go to the politics of destruction or personal attacks or yield on criticizing people's intelligence or whatever have you... Cut that out too. Let's be a better community. I repeatedly call upon the Tezos foundation to tell its community to stop criticizing Cardano and calling it's "a scam project". So, I'll call upon my own community, I have seen things that shouldn't have happened. Certain members of Cardano community replying to people over twitter, replying to people who criticize us have resorted to personal attacks and so forth. Again, just ignore them , mute, let's embrace unity, let's embrace being better, yes, occasionally you got to kick people in the teeth especially when people are lying and what you do is you call them out on the lies that they've made. You specifically point out where they have done things that are a bit crazy or disingenuous and dishonest.
For example, we had a meeting today with Ethereum classic and it was blatantly apparent to me that this process has been set up to fail and be exclusive and prevent alternative ideas from a certain power structure from being held. So, I made a 30-minute whiteboard video where I not only called it out but I proposed an alternative and said this is how we're going to transcend that process and get to a much more productive way of doing things. Some of the criticism we have is justified because of product delays or because people don't fully understand who we are and what we're trying to do and obviously there's history there. So, first and foremost, let's reply with facts. First and foremost let's reply with dignity and respect and empathy for the other person's position and you know what? If they continue to push forward then you kick him in the teeth and you say it's obvious you don't want to have a conversation. You're a troll, but to my community please do this and please have this level of respect and dignity with others and with each other.
For example, we right now have a lot of debates with small stake pools versus large stake pools, there's plenty of people floating around with differences of opinion and our mantra should always be disagree without being disagreeable. People are going to have other values people, are gonna have differences of opinion and people are gonna have different perspectives. You can't change that reality nor should you. We all have the right to think and have differences of opinion but we also should expect a dialog that's fair and has empathy in it and so I call upon everybody to preserve that decorum as we move forward and also understand that some days we wake up we have to do things that are non-Cardano related in order for us all to be successful because not all the world will ever be Cardano related. We always need partners whether it be great pieces of hardware like Ledger and Trezor or exchanges to work with different wallets and sometimes those partners do stuff with us and sometimes those partners do things with other people. We have friends, we have projects we admire and respect.
For example, I've expressed repeatedly great admiration for the Algorand project. I think they're doing a phenomenal job and they have great leadership with Silvio Micali. I think the research and the engineering there is top notch. I personally believe Cardano is better. That's because we built it and that's because we think we have a better strategy to market and ultimately the market's going to decide which standards to go with and whether it's going to be many standards or a consolidation. That's not my decision. I just have to wake up every day and fight for the things I believe in. That said, never once have we ever criticized Algorand because they are in essence the model of empathy and dignity and good communication and being very proactive at focusing on solutions when they make announcements. They make announcements about new things that they're doing and new partners that they have and never once have they ever criticized another project or engaged in fanboyism. That's a great community, that's a great project and it's a model for where the space should go and I admire that deeply and greatly especially when you contrast it with other projects that have been less empathetic in their history.
We all have our problems, we all have our issues. I know that we all can be better and so that's my final point. Let's do that. Let's be better as an industry. Let's be a bit friendlier and let's invest the time and effort necessary to really understand and listen to each other because ultimately I think that's going to get us where we need to go and be able to get us to a point where we have that adoption of millions and billions of people and fundamentally change the fabric of society.
Otherwise we will be victims of our own success and descend into tribalism and descend into sectarian violence and then ultimately destroy the entire industry because it will become co-opted by large companies who use a surface-level marketing to take the brand, take the notion of a blockchain but then install centralized authorities behind them and in which case we've lost. I don't want that to happen I want the movement to succeed. I want us to understand each other and I enjoy having great competitors sometimes working with them sometimes fighting them in the battle of the markets, in the markets of ideas and ultimately I think we as a community have a chance to also be a model for everyone else.
So, let's do that. Thank you...

RiB Newsletter #13 – Stuck inside, hacking away

It was another month in 2020, like previous months in 2020. Stuck inside, hacking away.
We don’t see a consistent blockchain Rust theme to highlight this month, but interesting new Rust crypto and blockchain projects continue to be launched. They are noted in the “Interesting Things” section.
Oasis launched what will probably become their mainnet. Congrats to them!
Ethereum 2 keeps creeping closer, and it looks like Lighthouse, in Rust, might be the fastest implementation.
The Holochain team asked that we highlight the Holochain DevCamp, running until August 27th. Now is your opportunity to learn more about the project. There are a number of other online blockchain hackathons going on this summer, noted in our “Events” section. Could be a good way to spend time this summer instead of going to the beach.
Well, anyway, keep on hacking.

Thanks

This edition of RiB was produced with contributions from Darosior, James Waugh, Ken Shamir, Paulii Good, Taylor Lee, Brian Anderson, and Aimee Zhu. Thank you for your help!
RiB needs help to keep up with Rust blockchain projects. If you follow a particular project, or otherwise find information that is beneficial to the Rust & blockchain community, please contribute to the next issue. Either submit a PR to the #14 draft, or Tweet @rust_blockchain.

Project Spotlight

Each month we like to shine a light on a notable Rust blockchain project. This month that project is…
electrs.
electrs is a server for the Electrum Bitcoin wallet, written in Rust. Electrum is a light wallet that needs to connect to a server to transact with the Bitcoin network. Although there are public Electrum servers, and they are safe to transact with, they can deanonymize users, so it might be prudent to run one’s own Electrum server, like electrs , or bwt (also written in Rust).
As mentioned recently in a blog post, Blockstream, one of the primary Bitcoin developers, uses electrs in its block explorer, esplora, which is live at blockstream.info.

The complementation of blockchain and IoT (Internet of Things)

Although blockchain technology is well known as the underlying technology of bitcoin, its potential now goes beyond the case of cryptocurrency. Currently, the industry is investigating the use of blockchain as a tool to better secure the Internet of things (IoT) network, thereby reducing the huge risks associated with the Internet of Things.
There are many levels in the IoT ecosystem. The weakest layer is the sensors--when all these sensors gather information, they become the point of entry for hackers. The connection between the sensor and the cloud processing unit is another weakness. Using blockchain technology, it is possible to ensure the connection between all the sensors in the area through a specific programming language, where several links in the program must be confirmed by some algorithm that each transmission is known to them and understood. For example, if someone tries to send you information about temperature, and the temperature will be transmitted in a certain way over a certain range, that information will be accepted. This information is then verified through the blockchain to ensure that everyone receives the same information. You can also add blockchain stacks at multiple levels depending on how deep you want them to be and how fast you want them to be processed.
The security issue in the Internet of Things is the same as it is in any kind of network--the challenge is considerable. First, there are technical limitations. Even if you have the best encryption, the best firewall, you can't say your system is 100 percent secure. Sooner or later, someone smarter than you will crack the encryption or firewall.
The other big problem is the users. Not everyone is tech-savvy, and not everyone understands the importance of changing passwords often, or not clicking on links they can't recognize, etc. The non-technical user is the weak point in the system, which can also be the entry point for hackers.
Another challenge is the different types of hardware and software we can use. Therefore, there will be a compatibility process problem, and this will also create vulnerabilities that hackers can access.
Blockchain is not an attempt to address these issues. Instead, the technology deals with processes, not components, and not software. Instead of solving every software and hardware problem, blockchain changes the process of identifying and approving who enters. Blockchain looks at these issues from a completely different perspective.
Blockchain, of course, has its problems, namely storage. At this moment, we have to store all the pieces of information that are being processed, and over time this information will accumulate. We need some kinds of hardware that can handle all this information.
Expanding the blockchain is another challenge. If we can overcome this expansion problem by distributing blockchain in a way that only addresses the very important areas of the Internet of things, the ones we worry about, then there will be no problem. Mass adoption of blockchain remains a challenge. That's why so far we don't see many big companies (except IBM) using blockchain.
Many companies, from banking to insurance to healthcare, are considering blockchain as a starting point to address these issues, but all are using it for special purposes to ensure that its use is limited to specific, highly sensitive areas.
A lot of big companies realize that blockchain could be a solution, so I think eventually these companies will come up with their algorithms, their systems. We could be facing the same problem that the Internet of things is facing right now, which is that no one company can be an industry standard. Alexa, Siri, and Google Home, each of which could be the center of the Internet of things, each want to dominate the market. The result could be big competition, or perhaps these big players will learn the benefits of being part of each other's market.
What will happen when blockchain technology is applied to the Internet of Things? What I hope is that these big companies in finance or insurance will adopt this technology and see it as a way to save money, save time, solve problems, whatever, and I hope that these companies will start investing in this technology. This will be the driving force behind the development of this technology. Blockchain seems to be a much more secure technology than what we have today. It's smart to choose blockchain, but is it the best technology? I think time will tell. However, with all the information we have so far about the technology, these companies are wise to invest in it. To get the attention of these companies, we need a business model, and the technology needs to be further developed to make it easier for people to deploy blockchain. And we need the government's supervision and understanding to recognize blockchain as a technology that can ensure the security of sensitive information. That's what we're working on.
We hope that we can realize the blockchain certified products, and at the same time realize the goal of establishing a connection between the blockchain certified products. Blockchain device to achieve plug and play. If we can do that, then these violations, and the hacking we hear about, will be less.

Tkeycoin — security, that’s what we’re betting on

Tkeycoin — security, that’s what we’re betting on
Today we will talk about the security of using the Tkeycoin platform and the TKEYSPACE mobile blockchain wallet.
Tkeycoin is a peer-to-peer payment system based on p2p principles and the concept of electronic cash. P2P technology is a fairer means of mutual settlements between users and companies around the world. Modern payment systems are imperfect and may depend on the will of high-ranking officials.
We approached the market from an economic and scientific point of view, borrowing the best from Bitcoin, Ethereum, DASH, and other alternative currencies, mixing modern concepts and building on the global experience of IBM, Microsoft and a number of other companies and research.
The Tkeycoin blockchain is protected by various mechanisms that include advanced cryptographic methods and mathematical models of behavior and decision-making. Blockchain technology prevents duplication or destruction of digital assets.

https://i.redd.it/idy42g9rntx41.gif
In addition to providing security and recording transactions in registers, cryptography also plays a role in ensuring the security of wallets used to store Tkeycoin. Paired public and private keys, which respectively allow users to receive and send payments, are created using asymmetric encryption or public-key cryptography. Public keys are used to generate digital signatures for transactions, which allows you to authenticate ownership of the coins being sent.

https://i.redd.it/95yuky0tntx41.gif
The asymmetric cryptography architecture does not allow anyone other than the owner of the private key to access funds stored in the cryptocurrency wallet, so these funds are kept safe until the owner decides to spend them.
In simple words, in the Tkeycoin peer-to-peer system, only you are the real owner of your money and only You have access to it.
Using tools such as a local Tkeycoin Core wallet or TkeySpace provides you with reliable storage, privacy, and security.
TkeySpace, in turn, adds maximum usability by combining the highest level of security and easy intuitive design.

https://i.redd.it/f0de51vuntx41.gif

How does TKEYSPACE provide security?

TKEYSPACE is one of the first applications that support blockchain in a mobile device and is also the first decentralized application of the TKEY platform.
Its serverless architecture provides the highest level of security for storing all assets in the application. unlike centralized applications that are managed by companies, TkeySpace does not have a Central management authority and operates in accordance with all the principles of peer-to-peer networks.

https://preview.redd.it/4bret8hwntx41.png?width=1253&format=png&auto=webp&s=535c5d879a36eac4ca8c807ee7af1b5fe05e12a9
As we said above, the wallets in the blockchain have a public and private key. Centralized applications usually store users ‘private keys on their servers, which makes users’ funds vulnerable to hacker attacks or theft.
TkeySpace-stores the encrypted key only on the user’s device and in encrypted form. The encrypted key is displayed as a mnemonic phrase (backup phrase), which is very convenient for users. Unlike complex cryptographic ciphers, the phrase is easy to save or write. The backup phrase provides the maximum level of security and thanks to its usual appearance, an attacker is unlikely to ever guess what these words are and what they are for.
A mnemonic phrase is 12 or 24 words that are generated using random number entropy. If the phrase consists of 12 words, then the number of possible combinations is 2048¹² or 211³² — the phrase will have 132 security bits. To restore the wallet, you must enter the mnemonic phrase in the strict order as it was presented after generation.
And so that you do not get confused in the definitions and concepts, we will briefly describe simple and clear principles of how it all works. Let’s look briefly at the factors.

Lock Screen

The simplest thing that protects your phone from unauthorized access is Pincode, a snake, a fingerprint or a Face Id login. And it would seem that this is related to TKEYSPACE?

  • At a minimum, it is almost impossible to open new mobile devices and pick up a pin code, even in the case of theft, most often the factory settings are reset, which leads to the deletion of all data on the phone, respectively-your funds are safe even for this reason.
  • Even if there was some “craftsman” and somehow managed to change the pin code on your device, the TKEYSPACE app will automatically delete all the keys and backup phrases, the wallet will simply be empty, and the attacker will be left with nothing.
As we can see, even a simple screen lock with a pin or fingerprint protects your data. It’s not as simple a screen lock as you and I might think.
Every platform, whether it’s Android or AppStore, uses specialized key stores. Cryptography, symmetric and asymmetric encryption, keys, and certificates are directly related to this task.
Keys and certificates that are used to protect information must also be securely protected. Android uses Keystore, a certificate and a Keystore, for this purpose.
Keystore is a specialized secret data store that is used by Java applications to encrypt, authenticate, and establish HTTPS connections.
For two-way authentication, the client and server exchange certificates, respectively, and the server and client must have a Keystore with a private/public key pair and a certificate. In other words, the Keystore is used to store keys and certificates that are used to identify the key owner (client or server).
Starting with Android 8, the encryption systems have been upgraded, the system is checked for signs of hacking at startup, and the screen lock allows you to restrict access to the device. Data encryption and the use of keys ensure the security of information when it is stored and transmitted.

https://i.redd.it/2c0b9re1otx41.gif
In the new version of the OS — Android 9 (Pie) — the developers also added support for hardware to protect against unauthorized changes.
Android apps run in an isolated software environment that restricts access to your information to other apps. OS components are also protected, which prevents attackers from exploiting system errors for their purposes.
Android uses both hardware and software to protect users and their data. Therefore, even at the operating system level, there are a lot of security factors. Of course, if you “flash” the phone (change the factory firmware) and enable Root access, this will reduce the security of Your device, but this is more an exception than a rule and such changes are usually introduced by very experienced users.
IOS uses Keychain — a specialized database for storing metadata and confidential information. Using a Keychain is the best practice for storing small pieces of data that are critical to your apps, such as secrets and passwords. In addition to the Keychain, Apple provides a full range of maximum protection for Your device.
And so we will continue,

Passcode in the app

Now we understand that to get access to the tools, an attacker needs to hack the hardware security of the Google and Apple giants to somehow get access to the app, which is impossible.
To increase security and eliminate other risk factors, we have included an access code (secret code) in the app.
You set an additional level of security by enabling a pin code to log in to the app. The access code additionally encrypts all data stored in the app.
Just so you understand — it’s not just numbers that you enter on the screen, this combination affects the ciphers inside the app. When creating a key, a user interface element is called. when the user swipes the screen, the application receives a random set of bytes — thus, all information is additionally covered by a new layer of cryptography.
And as we said above, if you try to disable the pin code, the app will delete all the data, and the attacker will be left with nothing.
As we have already realized, only 2 of these factors provide the maximum level of security for the TKEYSPACE application.
And the most important thing is that the application runs on the blockchain, which guarantees its full Autonomous operation, data immutability, and privacy.
Generation of new addresses, absence of accounts, phone numbers, e-mail and other personal data-provides you with a social level of security, which is a huge advantage in our time.
In a world where security is based on the level of cryptography, attackers try to influence You with the human factor using social engineering, so when you use applications with accounts, phone numbers, you have more risks.
Social engineering is a method of obtaining the necessary access to information based on the characteristics of human psychology.
For example, a copy of a SIM-card has become a new tool for fraudsters, but there is no personal information in TKEYSPACE, so even such groups of fraudsters can’t get access to your funds.

You don’t have to worry about security — it’s already built into the TKEYSPACE system.

A mixed encryption system based on the principles of computational complexity, with the deterministic generation of signatures using elliptic curves, provides absolute security and safety of user funds, and reserve phrases will help you restore funds at any moment.
A mnemonic phrase is 12 or 24 words that are generated using the entropy of random numbers.
If the phrase consists of 12 words, then the number of possible combinations is 2048¹² or 211³² — the phrase will have 132 security bits. To restore the wallet, you must enter the mnemonic phrase in the strict order as it was presented after generation.
Only you and no one else has access to the phrase. When you get the key, the app has restrictions on the screenshot, and the clipboard is disabled, which protects against malicious software.
It is you, as a user, who sees the phrases, and everything in the device is encrypted, the blockchain architecture protects against hacker attacks, information forgery, and other hacks.
For those who are a bit obsessed with persecution mania, we offer a small lifehack:
Buy several USB drives, connect them to a device that does not have access to the Internet, preferably on a clean operating system, create a text file, write backup phrases there, and encrypt the USB drives with passwords.

https://i.redd.it/shan90o4otx41.gif
Once again, to ensure security and easy recovery, it is enough to record backup phrases once and make several backups. you do not need to resort to an additional encryption method, because we have already done everything for you :)

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

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.

https://preview.redd.it/3t3z6hkbxel31.png?width=1920&format=png&auto=webp&s=ac989c2752c726e10d2291eb271721ceaa332a30

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.

https://preview.redd.it/xew1eu1exel31.png?width=1558&format=png&auto=webp&s=df960ded46d40fc9bf0ae8b54ff3b3b86276708a
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.
https://twitter.com/gverdian/status/1151549142235340800
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?

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/4axzxx57wel31.png?width=1561&format=png&auto=webp&s=a8c3de8468ef9b67bc1db75cffbef81ef8c0aa70
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/m9036lzfwel31.png?width=1169&format=png&auto=webp&s=50e54198a97106b3921f79ca928f7e808a5529d7

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.

PCHAIN & Gate.io AMA Summary

PCHAIN & Gate.io AMA Summary

https://preview.redd.it/tpke0a4ckmk41.jpg?width=1400&format=pjpg&auto=webp&s=6f48550202be5ec32428a0edf5214954dcd345cc
Glad to have a great AMA with Gate.io on Feb.13th, 2020. Read patiently and you will get more known about PCHAIN and the future of PCHAIN.
For the AMA in Chinese, welcome to visit: https://www.gate.io/help/livetext/17312
Gate.io: Very happy to invite Dr. Jeff, founder of PCHAIN as our guest today!
Dr Jeff: I am very happy to receive an exclusive interview with Gate.io to share and exchange some things about the development of PCHAIN ​​with you.
Gate.io: Dr Jeff, you were engaged in Internet finance in 2017. Why did you want to do PCHAIN ​​as a public chain?
Dr Jeff: The development path of the Internet is that applications are king. You can see that many good Internet companies are doing applications. The blockchain is the next generation Internet. At that time, considering applications was a very good place to stay, and the best direction. It is the financial sector. At the time, I was the chief scientist of Internet finance at IBM and the head of the blockchain. At the time of 2015 and 2016, Ethereum was also very early. But after completing the application discovery, I found that the underlying technology is not enough. All applications need a good public chain as the basic support. It is in line with the stable development law and it is gradual, so I decided to do this underlying building block. In addition, many functions of Ethereum have been criticized, such as performance. Many public chains 2.0 and 3.0 have emerged to solve the performance problem-TPS, and we have also made many innovations. From TPS, interoperability, cross-chain to application direction by 2020, changes are very fast. Of course, we have also achieved very good results on TPS: Under the 1064 intercontinental (Asia, Europe, America) node environment, it can support 256 childchains to produce blocks in parallel and interoperate with the main chain without issue. The test network measured 126,000 TPS, theoretical TPS is 180,000 TPS, and can be infinitely expanded horizontally. This is not difficult from a technical perspective in the local area network, but it is difficult to achieve it in a transcontinental environment. This is a very good foundation, and we will develop applications in the future.
Gate.io: Users ask: How do you think of the progress made in PCHAIN ​​and how do you think of Private CCC?
Dr Jeff: This is what I want to talk about in this AMA. One direction is DeFi, including Staking. In addition to these two directions, more opportunities from the applications in the industry. In terms of industry opportunities, we have a pioneering layout, which is to propose a new concept: commercial childchain, Private CCC. Because the domestic regulatory environment is difficult to achieve large-scale direct public chain applications in China, everyone expects the form of alliance chains. However, the alliance chain has limited imagination space, produces results in a small scope, and the communication link between the alliance chain and the public chain does not exist. It is equivalent to setting up many small local area networks, but now everyone is directly connected to the Internet. We did a multi-chain commercial childchain architecture at the time, including 256 childchains in parallel worldwide, also to verify the scalability and technical stability of this architecture. A question of mutual trust. How to trust it? Through the interaction between the main chain and the childchain, the information on the childchain is continuously updated to the main chain. When an alliance chain wants to know the information of its alliance chain, it can fully trust the information recorded on the main chain in history. This will surely link everyone together and is in line with China’s policies. This is a very important logic that we propose for the commercial childchain. It is a consideration and design oriented to supervision and future-oriented.
Gate.io: When did PCHAIN ​​start?
Dr Jeff: The white paper was released at the end of March 2018, and the mainnet was launched on March 30, 2019. In less than a year, the main chain has generated more than 10 million blocks. Let’s take a specific example: Ethereum launched the mainnet in July 2015. Until this year, about 5 years already, the total block is 9 million.
Gate.io: Will it produce invalid information accumulation?
Dr Jeff: Yes, but there is a follow-up solution, which is SmartData-Intelligent Data Processing, which was released last year. It is scored on this framework. It is different from the simplest highest TPS. In the past, many blocks will be empty. Redundancy is even worthless, which will put a lot of pressure on the node disk. After the release of SmartData reduction, it successfully compressed 200G to 20G, which is almost 10 times compression. In theory, mobile phones can run on it. But because of some bandwidth requirements, the subsequent continuous evolution process, the ultimate goal is to make the nodes lighter and lighter and let more nodes access.
Gate.io: We are also mining at Pos nodes. Staking is hot in 2019, what do you think of Staking?
Dr Jeff: Halved, burning is also very hot this year. Why is burning important? I think it is related to Staking. Staking is naturally an inflation. There will be more and more tokens. Only burning will make the value continuously increase.
Gate.io: How did you consider this piece of PCHAIN?
Dr Jeff: We have such a mechanism for planning POS in the white paper, and we have always believed that it is leading the technology development trend in the industry. People who have read the PCHAIN ​​white paper will understand that PCHAIN ​​is also a halved token. Like Bitcoin, our mechanism is also halved in 4 years. This year is the second year. Second, the total amount is constant. How much Ethereum will issue on the original basis each year, and the newly mined Token on PCHAIN ​​is limited to 15% of pos. If it cannot be mined already, the owner on the childchain can go to the market to buy Token and inject it into the childchain, so that the miners of the childchain have the motivation to continue mining. This is different from Bitcoin and Ethereum.
Gate.io: Users ask: When will the commercial childchain start?
Dr Jeff: First quarter. The most important part of the year 2020 plan is the commercial childchain. The commercial childchain project in the first quarter must be confirmed. Although the impact of the new coronavirus, we are still very confident and communication has been ongoing.
Gate.io: How many commercial childchains are expected to be in PCHAIN ​​this year?
Dr Jeff: It’s hard to predict, but I can tell you that there are three childchains moving forward. Recently, there have been successive partners and domestic top software developers communicating. Because of the high incidence of blockchain applications this year, if they cooperate with large-scale software development, there may be a relatively explosive momentum.
Gate.io: What do you think of Staking?
Dr Jeff: Many of us still think from a technical point of view. POW has been for many years. The disadvantages of power consumption have been around for a long time, but the degree of decentralization is high. The future trend must be the large-scale application of the blockchain. This is a trend, and efficiency is very important. All projects are talking about POS. Staking is a derivative of the consensus mechanism. Only by holding the token in it will we focus on its security . Many early projects also exposed a lot of problems, which gradually reduced by half.
Gate.io: What are the shortcomings in the development process that need to be improved?
Dr Jeff: The shortcomings in the market are still relatively lacking. In 2018, our focus is all overseas, so the domestic voice is relatively small. After 2019, it has been developing and strengthening in the domestic market area, so that more people recognize PCHAIN.
Gate.io: I think we have our own wallet?
Dr Jeff: Yes, the current function can be staking, and a cross-chain transfer can be performed between the main chain and the childchain. Its basic positioning is a technology-oriented wallet, and the future plan is also in terms of technology. For example, quickly put some interesting applications (especially Ethereum) on PCHAIN, which is also a relatively important function. We are compatible with EVM of Ethereum. An Ethereum application developer can put it on PCHAIN ​​with almost no code changes.
Gate.io: What other application scenarios does the blockchain have in addition to the cryptocurrency circle? How to balance speed and decentralization under safe conditions?
Dr Jeff: Impossible triangle of blockchain, security, efficiency and security, in a certain perspective, there is no solution. The fundamental problem of balance lies in whether the consensus algorithm itself is good enough. Our original new consensus algorithm is called PDBFT consensus algorithm. Last year, everyone talked more than BFT, VIF random numbers, and a BOS data compression, including the Cosmos overseas team said that BOS has been integrated, our PDBFT integrates these three factors together, let the communication volume from the square of N to N, the degree of decentralization has been improved while ensuring efficiency.
Gate.io: The current commercial childchain is Private Chain. How to connect to Public Chain?
Dr Jeff: Cross-chain. In the future, in addition to its own main chain and childchains, it can also cross other chains.
Gate.io: Why did you choose to be listed at Gate.io?
Dr Jeff: Gate.io is one of the few exchanges that is very consistent with our basic thinking and philosophy of work, including founder Mr. Han, who has been persistently committed to technology, and even we have studied technical details for several hours. We have also contacted the founders of many exchanges. There are not many people like founder Mr. Han who know every detail very well. Secondly, Gate.io has a good community foundation. I think Gate.io is also in the world TOP position, its transaction volume and non-wash trading order are very real, this is very consistent with the spiritual pursuit of the blockchain.
Gate.io: Our users ask you, how to reduce the number of communication handshake to maintain consistency? The current workload proofs are all based on Sha256. Is there any further progress?
Dr Jeff: The Sha256 workload proof belongs to POW’s consensus algorithm and belongs to an axiom proof. Based on this axiom, everyone agrees that its decentralization is very good. However, in all POS, the emphasis is on cooperative handshake, which cannot be reduced from the perspective of collaboration, but it can reduce the amount of information transmitted during the collaboration process. Example: The reduction of communication volume makes the amount of collaboration less. Through communication compression, a lot of people shaking hands at the same time also improve the efficiency.
Gate.io: If the user wants to know some information, in addition to the official website and public account, and where can I find the desired content on the domestic platform?
Dr Jeff: If you prefer technology, you can go to github to watch it. There have been 23 major and minor upgrades since the mainnet launch last year.
Gate.io: What are the main adjustments to the mainnet upgrade?
Dr Jeff: It’s mainly rewarding. It’s a small part of staking for optimization.
Gate.io: Can you talk about future plans?
Dr Jeff: In the future, the focus will be on the commercial childchain. In addition to this, SmartData will be more important. At present, it is relatively new. Like Oracle, it is also part of SmartData.
Gate.io: How many people are using the new commercial childchain?
Dr Jeff: Generally speaking, there were thousands of data on a commercial childchain last year.
Gate.io: Some of the businesses on PCHAIN ​​are private chains. How can we get to the common chain in the future?
Dr Jeff: The commercial childchain itself has such a switch, uploading a part of the hash value to the public chain, and the user can operate it if he wants to open the switch, which depends on the consensus of these enterprises participating in the alliance chain.

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. 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.

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
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.
