Huobi Exchange Review

A HISTORY OF HUOBI
Huobi was founded in 2013 by their current CEO and chairman, Leon Li. Li’s background includes having attended Tshingua University, specializing in Automation. Before starting the Huobi Group, Li spent time as a computer engineer at Oracle. In December of 2013, Huobi was named as the largest digital asset exchange operating in China. 2017 saw Huobi extend their limbs into Korea, Singapore, and Japan.
Currently, Huobi has headquarters of various financial sectors based in: Singapore; South Korea; Japan; Australia; Indonesia; Russia; Argentina; Thailand; and China. The company has strived to give customers not only a great exchange, but a great resource for any service one may need. Despite the many difficulties faced with Chinese government in regards to cryptocurrency laws, Huobi has managed to adapt to the changes and thrive globally, eventually branching off into various sectors including venture capital, a cryptocurrency wallet project, and a division dedicated to working with mining pools.

HUOBI'S PLATFORM
spot trading : Huobi offers several different platforms to serve any customer’s needs. For starters, Huobi offers a standard spot trading platform that operates similarly to many other spot trading platforms in the industry. The platform features a multi-timeframe chart, a depth chart, and integration with TradingView (including their tools). Customers are able to view the order book and the asset trading history, as well as their own personal order history. Limit orders, Market orders, and Stop-Limit orders are all available options for traders.
margin trading : For the trader that prefers to trade with a little more volume or risk, Huobi offers a Margin trading platform. Customers can apply for loans through Huobi to trade a greater quantity of cryptocurrencies and profit from the price spread. The original loan must be paid back, and accounts can be liquidated if the risk ratio falls below 110% (calculated as: [(Loaned Amount + Tradable Balance) Total Asset] / [(Interest Payable + Loaned Amount)] x 100%.) Traders can margin trade with Bitcoin; Ethereum; XRP; Litecoin; Bitcoin Cash; and EOS. These assets can be traded with USDT or BTC.
futures trading : Huobi also offers a Futures trading platform. While margin trading can be risky, trading contracts is said to be very high-risk. With that being said, Huobi offers Weekly, Bi-Weekly, and Quarterly contracts in Bitcoin; Ethereum Classic; Ethereum; EOS; Litecoin; Bitcoin Cash; XRP; TRX; and Bitcoin SV.
OTC(P2P) - The OTC, or over-the-counter, section of Huobi offers potential buyers and sellers a way to move large quantities of coins without exposure to the fickle exchange market. Certified merchants can register here, and slippage can be minimized by matching buyers and sellers directly instead of creating market orders.


HUOBI APPS
While you do have the online trading interface, Huobi does have computer programs and mobile apps that you can use.
I found that the PC programmes were more functional as they did not have to rely on the PC browser and were hence much faster. They also have better charting and you are in more control of your trading parameters. These programs are available on Windows and Mac devices.
However, if you are a trader that is always on the go, that is where the Huobi mobile apps come in. These were developed for the main exchange but you can switch to the derivative markets on the futures and swaps platform.
This was a pretty well designed application and you have one-touch ordering as well as some basic charting functionality. The app is available in iOS and Android and you can head on over to the respective app stores to get a sense of the feedback.


EXCHANGE SECURITY
Huobi operates a hot and cold wallet storage procedure. This means that they keep the vast amount of their coin holdings in an offline environment away from hackers. They then have a smaller percentage in “hot” wallets with multisig capability.
They also operate a decentralized server structure around the world which can ensure uptime irrespective of whether one of the servers goes down. You can think of this as effective load balancing.
Finally, they have anti DDoS measures in place. We all know that crypto exchanges are prime targets for Denial of Service attacks and it can be quite frustrating when these are perpetrated in peak market times.


IS HUOBI TRUSTWORTHY?
Huobi, like many exchanges in the space, has had, at one time, some shady history, but for the most part, has managed to maintain a clean reputation. Historically, Chinese exchanges have shown to operate in accordance with different standards, with many exchanges having to suffer at the will and whim of the Chinese government. Some of the controversy Huobi has seen in the past has been a result of this (particularly with the Chinese ban on ICO tokens). It should be noted that in 2017, the exchange did invest into “wealth-management products” using idle customer funds. This sort of activity shouldn’t be taken lightly.
However, with that being said, the exchange continues to turn over a large amount of volume. For the most part, the exchange can be considered a trustworthy platform to trade popular and exotic cryptocurrencies. This does not mean it is entirely safe to store user funds on the exchange, as the exchange (or the user funds) can be susceptible to risk at any given moment. No matter how comfortable one may be with the internet, one should always remember that the internet is not as safe as many would like to believe. Huobi does have measures in place in the unfortunate event that an account is breached, and if verifiable, the customer may be able to retrieve lost funds.
A unique feature offered on Huobi is their Official Media Authenticator. This essentially lets users enter the URL of a content channel to see if the channel is authentic. A feature like this, while seemingly simple, could save anyone from potentially losing their funds due to a scam or phishing website.


HUOBI REVIEW VERDICT
Huobi Global offers a signficant host of features to its users and has maintained its credibility over a long period of time. This is largely one of the main reasons it a ranked as a top 4 exchange by liquidity as its users trust their funds there.
After establishing itself in Asia, Huobi is trying to branch out and take on other areas of the globe which is great news for Western traders. Additionally, the Huobi prime platform could provide some great opportunities for the exchange users moving forward.

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.

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.

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.

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:
  • 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.

Overledger’s approach

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

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

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

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

Patents

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

Multi Chain Applications (MAPPs)

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

Treaty Contracts

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

The different versions of Overledger

Enterprise version

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

Community version

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

Where does Overledger run from? Is it Centralised?

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

The Team

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

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

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

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

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

What is a blockchain Operating system?

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

How is Overledger different to other interoperability projects?

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

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

But some Interoperability blockchains say they are infinitely scalable?

Overledger’s approach

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

And that was by design. I’m actually very proud of the fact that we thought of that and carefully designed that capability into the system.
This is the approach Quant have taken with their Blockchain OS, Overledger to solve Blockchain interoperability. Compared to other Interoperability platforms that are trying to achieve interoperability at the transaction layer by connecting two blockchains via another blockchain, these will be ultimately be made redundant once faster methods are released. Overledger is designed to be future proof by isolating the layers so it doesn’t matter whether it’s a permissioned blockchain, permissionless, DAG, Legacy network, POW, POS etc because it abstracts the transaction layer from the messaging layer and runs on top of blockchains. Just as the Internet wasn’t replaced by X25, frame relay, APM etc, Overledger is designed to be future proof as it just runs on top of the Blockchains rather than being a blockchain itself. So, if a new blockchain technology comes out that is capable of 100,000 TPS then it can easily be integrated as Overledger just runs on top of it.

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.

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

Treaty Contracts

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

The different versions of Overledger

Enterprise version

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

Community version

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

Where does Overledger run from? Is it Centralised?

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

The Team

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

The best Tezos Wallets

The best Tezos Wallets
Tezos is a decentralized blockchain that simplifies formal verification, a method that mathematically proves the accuracy of the code controlling transactions. The Tezos blockchain has its own cryptocurrency called Tezos (XTZ), a cryptocurrency with two main functions – a self-administration system and the ability to form launch contracts using its own programming language – Michelson.
If you decide to convert your fiat savings into Tezos or exchange other cryptocurrencies for XTZ, you may have to make a choice among reliable wallets for this. In this article we will look into the best Tezos Wallets so that can help you understand them better.

Hardware Wallets

Hardware wallets are not liable to spam, viruses, phishing attacks, or malicious of the system. Moreover, they provide a high degree of protection to the private keys. Below is the list of hardware wallets that can be used for XTZ.
https://preview.redd.it/j79t9vbgeth31.jpg?width=800&format=pjpg&auto=webp&s=d828387479fc4a2efed4fc857eb9bdf03f9878e9
  • Ledger Nano S
Nano S is a hard wallet from the product line of Ledger, a French manufacturer company. As all other Ledger products, Nano S traditionally looks like a USB flash drive. But this time, you will need to use the USB cable that comes with the wallet to connect to a computer. Ledger Nano S has a chip that is similar with chips on bank cards or biometric passports. Your private key is stored in an isolated environment and is effectively protected. Ledger Nano S also has a screen on it where you can see each transaction made. In case you lose your Nano S wallet, the account can be easily restored on any other Ledger device. Ledger Nano S supports over 20 cryptocurrencies including Tezos (XTZ).
  • Trezor Model T
Trezor T is the flagship model from the well-known Czech manufacturer SatoshiLabs. Model T has a color Touch-Screen display, an SD port and a quantity of supported coins – XTZ is among those coins. When Trezor T is not connected to the computer, it turns off and disconnects from the Internet. Thus, user funds are stored on the device beyond the reach of attackers. Trezor hardware case is ultrasonically soldered, making it difficult to be restored after being damaged.

Web Wallets

Web wallets can be a simple way to get started investing in cryptocurrency. All web wallets can be used right from a browser without the need of downloading software. Beyond that, many of web wallets offer free mobile apps.
  • TezBox Wallet
TezBox was the first GUI released for Tezos. The wallet was developed by the Tezos community and released during the ICO period. TezBox is available for web, desktop and mobile wallets with its user-friendly interface. Users may be assured that all private keys will be stored on their devices safely due to the secured wallet interface. TexBox is the first wallet integrated with hardware wallets Trezor and Ledger Nano S that gives it the increased security.

  • Guarda Wallet
Guarda Wallet is available as a Web, Mobile and Desktop Wallet and a Chrome extension. It supports more than 40 coins and 10,000 tokens as well as XTZ. The web wallet enables to access cryptocurrency from any modern browser, the website itself looks presentable and made convenient to use. Using the mobile wallet, you can create a new wallet or import an existing one. Besides the common functions such as storage, deposit/withdrawal of cryptocurrency, users can instantly buy the exact amount of cryptocurrency using a bank card or exchange coins and tokens.
  • Magnum Wallet
While Magnum is a multi-asset wallet, one of the best known assets it supports is Tezos (XTZ). Being a light wallet, you do not need to download the full blockchain of any of the cryptocurrencies it works with. The wallet does not keep users’ personal information. As Magnum is a web wallet, it has the extra benefit of being available for nearly any platform, easy of access from any kind of device with an internet browser. Magnum wallet also supports Ledger devices so those can be easily linked to the app.

Mobile Wallets

Mobile wallets are used on your smartphone via an app. Similar to Apple or Google Pay, you can use mobile wallets when shopping in physical shops as cryptocurrencies become more popular and acceptable. Mobile wallets may be safer compared to online wallets and also be easy to use on the go.
  • Trust Wallet
Trust is a wallet for tokens of ERC20 standard, tooled for mobile devices. It offers simple installation and affordable feature set, that does not require additional user skills and abilities. Trust Wallet and Binance are working on new features, including market monitoring, user networks, test networks, and deep integration with the Binance infrastructure. Trust Wallet already supports Tezos as well as other digital currencies.

  • AirGap Wallet
AirGap is a wallet, that allows you to keep your cryptocurrency securely on your mobile. AirGap is a system with two device access: you can use your old mobile device as a hardware wallet using the AirGap Vault app to keep the private key there; while your working smartphone will have the wallet itself. The connection occurs with QR codes, this ensures a genuine one-way communication between AirGap Wallet and AirGap Vault. This implies that no private information ever leaves the air-gapped old phone. Besides Tezos, AirGap supports diverse amount of cryptocurrencies.
  • Tezos.Blue Wallet
In spite of being a lightweight wallet, Tezos.Blue does not scant on security or its features. It is an original app and that is why it gets strong protection straight from the operating system. Using the Tezos.Blue you will have actual updates from the network for a truly live operational comfort. Tezos.Blue is also available in a desktop version. Tezos.Blue is also available in a desktop version.

Desktop Wallets

Desktop wallet can be downloaded and installed on a computer. Desktop wallets may be safer if your computer is not, or more preferably, has never used the Internet connection. Desktop Wallets are perfect for storing large amounts of crypto that you don’t want to use on an everyday basis.
  • Atomic Wallet
Atomic is a convenient, easy to use and safe cryptocurrency wallet, that receives the preferences of many users around the world. It is a decentralized multicurrency wallet that is known in the crypto community for supporting more than 500 cryptocurrencies including Tezos. The primary goal of Atomic Wallet is not just to store cryptocurrency, but also to create a strong ecosystem with many functions.

  • Atomix HD Tezos Wallet
HD wallets (hierarchical deterministic wallet) are the wallets that use a single 12 or 18-word mnemonic phrase that is used to identify following addresses and private keys in a wallet software. Atomix is HD wallet that supports Tezos, it merges benefits of decentralized and centralized exchanges. With Atomix, all private keys are kept encoded on the computer. No identity verification or registration is required to use the wallet.
  • Simplestaking
Simplestaking is Tezos focused wallet being a web app and desktop app with support for hardware wallet Trezor Model T. The wallet is developed using NgRx state management and Angular framework.
  • Galleon Tezos Wallet (Tezori)
Galleon is a smart open source wallet for XTZ that supports both hardware and software wallets on Windows, Linux and Mac. It was developed by Cryptonomic and funded by the Tezos Foundation.
  • Tezos CLI Wallet
The Tezos CLI wallet can be used by those users who have some coding understanding while it requires the use of command lines. Tezos has mentioned the wallet on its website and has been audited by an independent external security inspector. As the Tezos CLI needs some level of command line knowledge, it can be quite difficult to use.

How to keep your wallet safe

A cryptocurrency wallet can be regarded as a regular wallet with money, but it has advanced features, which increases the level of risk. Simple rules will help prevent the loss of your own savings:
  1. Do not store large amounts for long periods on wallets that do not provide full control. It is better to store large amounts for a long time only in wallets that provide full control over the private key and, accordingly, over digital assets. This will help protect your coins against fraud and cyber attacks.
  2. Encrypt information and back up private keys. In case of reinstalling the PC or the occurrence of force majeure situations, this will help to restore access to the wallet quickly.
  3. Store secret keys on an offline device. It is preferable to use a platform that is not accessible for hacking via the Internet.
  4. Use reliable antivirus software and update it regularly. This will prevent the leakage of personal data that hackers can use to crack passwords.
  5. Register several types of wallets. It will allow you to distribute your funds and use the most suitable wallet depending on the situation.
If you use your Tezos wallet wisely and do not neglect the precautions, the risk of funds loss will be minimized.

The Exhaustive EOS FAQ

The Exhaustive EOS FAQ

 
With the large number of new readers coming to this sub we need to make information easy to access so those readers can make informed decisions. We all know there is an unusually large amount of Fear, Uncertainty and Doubt (FUD) surrounding EOS. Frankly, when clear evidence is provided it’s not that difficult to see EOS for the extremely valuable project it is. This post hopes to begin to put an end to all the misinformation by doing the following:  
  • Giving a clear and concise answer to the most frequently asked questions in regards to EOS.
  • Giving a more in-depth answer for those who want to read more.
  • Allowing readers to make informed decisions by making credible information easy to access.
 
As EOS climbs the ranks we need to recognise there are going to be a lot of skeptical readers coming over and posting their questions. Sometimes they will be irrational, hostile and often just looking for a reaction. We should make it our responsibility to welcome everyone and refrain from responding emotionally to provocative posts, instead providing factual and rational answers.
I will add to this post as and when I can, if you have any ideas or spot any mistakes let me know and I'll get them fixed ASAP. Im planning to add a bit on the team, centralisation and DPOS, governance and EOS VC shortly but please let me hear your suggestions!
 

FAQ

1. How do you registeclaim your EOS tokens before June 2018?

 
Answer courtesy of endless. If you have not done so, you will need to create a new pair of EOS public and private keys and register them with an Ethereum address. This only needs to be done once.
On or around June 1, 2018 all EOS Tokens will become frozen and non-transferable on the Ethereum blockchain. Not long after, I suspect that EOS community members will create a snapshot of token balances that carry over onto a new community generated and selected EOS blockchain. block.one will not be launching EOS blockchains or operating any of their nodes. Additionally, this is a community subreddit unaffiliated in an official capacity with block.one

Did you buy your EOS tokens on an exchange? (Courtesy of IQOptionCoin)
REMEMBER YOU ONLY NEED TO REGISTER YOUR TOKENS IF YOU BOUGHT THEM ON AN EXCHANGE. YOU DON'T NEED TO CLAIM THEM.
  1. Go to the EOS website https://eos.io
  2. Scroll down and select "GET EOS"
  3. Tick all the required boxes and click "Continue"
  4. Scroll down and click "Register"
  5. Select Metamask, MyEtherWallet, or Ethereum Wallet
  6. Follow the guide.
  7. Remember that the reason you need to register your Ethereum ERC-20 address is to include your EOS tokens in order for the balance of your EOS Tokens to be included in the Snapshot if a Snapshot is created, you must register your Ethereum address with an EOS public key. The EOS snapshot will take place prior to the 1 June 2018. After this point your ERC-20 EOS tokens will be frozen. And you will be issued EOS tokens on the EOS blockchain.
So PLEASE REGISTER your Ethereum address NOW, don't forget about it, or plan on doing it some time in the near future.
There are a lot of submissions about this in /eos, so rather than making a new one please reply to this thread with any questions you may have. Don't forget to join the EOS mailing list: https://eos.io/#subscribe and join the EOS community on your platform(s) of choice: Telegram, Discord and/or Facebook.
And remember, if anyone instructs you to transfer ETH to an EOS contract address that doesn't match the address found on https://eos.io you are being scammed.

2. How will the token the ERC-20 EOS tokens be transferred to the native blockchain?

 

Quick answer:

There isn't one! Read the long answer then read it again, registering your Ethereum wallet is mandatory!
 

Long answer:

Within 23 hours after the end of the final period on June 1, 2018 at 22:59:59 UTC, all EOS Tokens will become fixed (ie. frozen) and will become non-transferrable on the Ethereum blockchain.
In order to ensure your tokens are transferred over to the native blockchain you must register your Ethereum address with an EOS public key, if you do not you will lose all your tokens! I am not going to link any tutorials as there are many that can be found by searching Google and YouTube.
block.one is helping with the development of snapshot software that can be used to capture the EOS token balance and registered EOS public key of wallets on the Ethereum blockchain. It is then down to the community to create the snapshot. This snapshot can be used when generating a genesis block for a blockchain implementing eos.io software. block.one will not be launching EOS blockchains or operating any of their nodes.
 
Exchange Support
Some exchanges have announced that they will support the token swap. Although using this method will undoubtedly be much simpler than registering the tokens yourself it also comes with its pitfalls.
  • It is highly likely there are going to be multiple networks running on the eos.io software that use the snapshot. It is highly unlikely that exchanges will support them all.
  • It is highly likely that exchanges will not support airdrops that use the snapshot.
Exchanges that have announced support for the token swap include:

3. What does EOS aim to achieve?

 

Quick answer:

EOS.IO software is aiming to provide a decentralized operating system which can support thousands of industrial scale DApps by enabling vertical and horizontal scaling.
 

Long answer:

EOS.IO is software that introduces a blockchain architecture designed to enable vertical and horizontal scaling of decentralized applications. This is achieved through an operating system-like construct upon which applications can be built. The software provides accounts, authentication, databases, asynchronous communication and the scheduling of applications across multiple CPU cores and/or clusters. The resulting technology is a blockchain architecture that has the potential to scale to millions of transactions per second, eliminates user fees and allows for quick and easy deployment of decentralized applications.

6. Which consensus mechanism does EOS use and what are Block Producers?

 

Quick answer:

Delegated Proof of Stake (DPOS) with Byzantine Fault Tolerance. Block Producers (BPs) produce the blocks of the blockchain and are elected by token holders that vote for them. BPs will earn block rewards for their service, these block rewards come in the form of EOS tokens produced by token inflation.
 

Long answer:

Taken from the EOS.IO Technical White Paper v2:
“EOS.IO software utilizes the only known decentralized consensus algorithm proven capable of meeting the performance requirements of applications on the blockchain, Delegated Proof of Stake (DPOS). Under this algorithm, those who hold tokens on a blockchain adopting the EOS.IO software may select block producers through a continuous approval voting system. Anyone may choose to participate in block production and will be given an opportunity to produce blocks, provided they can persuade token holders to vote for them.
The EOS.IO software enables blocks to be produced exactly every 0.5 second and exactly one producer is authorized to produce a block at any given point in time. If the block is not produced at the scheduled time, then the block for that time slot is skipped. When one or more blocks are skipped, there is a 0.5 or more second gap in the blockchain.
Using the EOS.IO software, blocks are produced in rounds of 126 (6 blocks each, times 21 producers). At the start of each round 21 unique block producers are chosen by preference of votes cast by token holders. The selected producers are scheduled in an order agreed upon by 15 or more producers.
Byzantine Fault Tolerance is added to traditional DPOS by allowing all producers to sign all blocks so long as no producer signs two blocks with the same timestamp or the same block height. Once 15 producers have signed a block the block is deemed irreversible. Any byzantine producer would have to generate cryptographic evidence of their treason by signing two blocks with the same timestamp or blockheight. Under this model a irreversible consensus should be reachable within 1 second."
 

7. How does the voting process work?

 
The voting process will begin once the Block Producer community releases a joint statement ensuring that it is safe to import private keys and vote.
Broadly speaking there will be two methods of voting:
  1. Command Line Interface (CLI) tools
  2. Web portals
EOS Canada has created eosc, a CLI tool that supports Block Producer voting. Other Block Producer candidates such as LibertyBlock are a releasing web portal that will be ready for main net launch. There will be many more options over the coming weeks, please make sure you are always using a service from a trusted entity.
Remember: Do not import your private key until you have seen a joint statement released from at least five Block Producers that you trust which states when it is safe to do so. Ignoring this warning could result in tokens lost.
 

8. What makes EOS a good investment?

 
  • Team - EOS is spearheaded by the visionary that brought us the hugely successful Bitshares and Steem - arguably with two projects already under his belt there is no one more accomplished in the space.
  • Funding - EOS is one of the best funded projects in the space. The block.one team has committed $1B to investing in funds that grow the EOS echo system. EOS VC funds are managed by venture leaders distributed around the world to insure founders in all markets have the ability to work directly with local investors. Incentives such as the EOS hackathon are also in place with $1,500,000 USD in Prizes Across 4 Events.
  • Community Focus - The team is aware that the a projects success depends almost entirely on its adoption. For this reason there has been a huge push to develop a strong world wide community. There is already a surplus number of block producers that have registered their interest and started to ready themselves for the launch and incentives the EOS hackathon are being used to grow the community. A index of projects using EOS can be found at https://eosindex.io/posts.
  • Technical Advantages - See point 9!
 

9. What are the unique selling points of EOS?

 
  • Scaleability
    • Potential to scale to millions of transactions per second
    • Inter-blockchain communication
    • Separates authentication from execution
  • Flexibility
    • Freeze and fix broken applications
    • Generalised role based permissions
    • Web Assembly
  • Usability
    • Elimination of transaction fees
    • True user accounts with usernames, passwords and account recovery (no more having to remember long cryptographic keys)
    • Web toolkit for interface development

EOS Whitepaper
 

10. Is there currently a working product?

 

Quick answer:

This depends entirely on your definition of working product. If a fully featured developer release meets your definition then yes!. Otherwise the public release will be June 2018.
 

Long answer:

EOS differs from other projects in that it aims to deliver a fully featured version of the software on launch. The Dawn 3.0 RC1 feature complete pre-release became available on April 5th. This version has all the features of the final release that is due June 2018. Further development will involve preparing the final system contract which implements all of the staking, voting, and governance mechanics. The common notion that there is no viewable code published is wrong and the initial Dawn 1.0 release has been available from September 14th 2017.
 
EOSIO V1 - June 2nd 2018
Dawn 3.0 RC1 - April 5th 2018
Dawn 3.0 Alpha - January 23rd 2018
Dawn 2.0 - December 4th 2017
Dawn 1.0 - September 14th 2017

11. EOS is an ERC-20 token, how can it possibly be a competitor to other platforms?

 

Quick answer:

The ERC-20 token is used only for raising funds during the token distribution; all tokens will be transferred to the native blockchain once launched.
 

Long answer:

EOS team has clearly stated their reason for choosing the Ethereum network when they described the rationale behind the ICO model. Specifically, the ICO should be a fair and auditable process, with as little trust required as possible. If you believe that an ICO should be fair, auditable, and trustless, you have no choice but to use a decentralized smart contract blockchain to run the ICO, the largest, and by-far most popular of which is Ethereum. Since EOS is intended to be a major competitor for Ethereum, some have seen this as a hypocritical choice. - Stolen from trogdor on Steam (I couldn’t word it any better myself).

12. Why do the eos.io T&C’s say the ERC-20 token has no value?

 
The EOS T&C’s famously state:
"The EOS Tokens do not have any rights, uses, purpose, attributes, functionalities or features, express or implied, including, without limitation, any uses, purpose, attributes, functionalities or features on the EOS Platform."
 

Quick answer:

This is legal wording to avoid all the legal complications in this emerging space, block.one do not want to find themselves in a lawsuit as we are seeing with an increasing amount of other ICOs. Most notably Tezos (links below).
 

Long answer:

This all comes down to legal issues. Anyone who’s been into crypto for 5 minuets knows that government bodies such as the Securities and Exchange Commission (SEC) are now paying attention to crypto in a big way. This legal wording is to avoid all the legal complications in this emerging space, block.one do not want to find themselves in a lawsuit as we are seeing with an increasing amount of other ICOs. Many token creators that launched ICOs are now in deep water for selling unregistered securities.
 
A filing from the Tezos lawsuit:
"In sum, Defendants capitalized on the recent enthusiasm for blockchain technology and cryptocurrencies to raise funds through the ICO, illegally sold unqualified and unregistered securities, used a Swiss-based entity in an unsuccessful attempt to evade U.S. securities laws, and are now admittedly engaged in the conversion, selling, and possible dissipation of the proceeds that they collected from the Class through their unregistered offering."
 
To ensure EOS tokens are not classed as a unregistered security block.one has made it clear that they are creating the EOS software only and won’t launching a public blockchain themselves. This task is left down to the community, or more precisely, the Block Producers (BPs). The following disclaimer is seen after posts from block.one:
 
"block.one is a software company and is producing the EOS.IO software as free, open source software. This software may enable those who deploy it to launch a blockchain or decentralized applications with the features described above. block.one will not be launching a public blockchain based on the EOS.IO software. It will be the sole responsibility of third parties and the community and those who wish to become block producers to implement the features and/or provide the services described above as they see fit. block.one does not guarantee that anyone will implement such features or provide such services or that the EOS.IO software will be adopted and deployed in any way.”
 
It is expected that many blockchains using eos.io software will emerge. To ensure DAPPs are created on an ecosystem that aligns with the interests of block.one a $1bn fund will be has been created to incentivise projects to use this blockchain.

13. Why is the token distribution one year long?

 
Official statement from block.one:
“A lot of token distributions only allow a small amount of people to participate. The EOS Token distribution structure was created to provide a sufficient period of time for people to participate if they so choose, as well as give people the opportunity to see the development of the EOS.IO Software prior to making a decision to purchase EOS Tokens.”
 
It is also worth noting that block.one had no knowledge how much the the token distribution would raise as it is determined by the free market and the length of the token distribution is coded into the Ethereum smart contract, which cannot be changed.

EOS.io FAQ
 

14. Where is the money going from the token distribution?

 

Quick answer:

Funding for the project was raised before EOS was announced, the additional money raised from the token distribution is largely going to fund projects on EOS.
 

Long answer:

A large portion of the money raised is getting put back into the community to incentivise projects using eos.io software. block.one raised all the money they needed to develop the software before the ERC-20 tokens went on sale. There are some conspiracies that block.one are pumping the price of EOS using the funds raised. The good thing about blockchain is you can trace all the transactions, which show nothing of the sort. Not only this but the EOS team are going to have an independent audit after the funding is complete for piece of mind.
 
From eos.io FAQ:
“block.one intends to engage an independent third party auditor who will release an independent audit report providing further assurances that block.one has not purchased EOS Tokens during the EOS Token distribution period or traded EOS Tokens (including using proceeds from the EOS Token distribution for these purposes). This report will be made available to the public on the eos.io website.”

15. Who's using EOS?

 
With 2 months from launch left there is a vibrant community forming around EOS. Some of the most notable projects that EOS software will support are:
A more complete list of EOS projects can be found at eosindex.io.
 

16. Dan left his previous projects, will he leave EOS?

 

Quick answer:

When EOS has been created Dan will move onto creating projects for EOS with block.one.
 

Long answer:

When a blockchain project has gained momentum and a strong community has formed the project takes on a life of its own and the communities often have ideas that differ from the creators. As we have seen with the Bitcoin and Ethereum hark forks you cant pivot a community too much in a different direction, especially if its changing the fundamentals of the blockchain. Instead of acting like a tyrant Dan has let the communities do what they want and gone a different way. Both the Bitshares and Steem were left in a great position and with Dans help turned out to be two of the most successful blockchain projects to date. Some would argue the most successful projects that are actually useable and have a real use case.
What Dan does best is build the architecture and show whats possible. Anyone can then go on to do the upgrades. He is creating EOS to build his future projects upon it. He has stated he loves working at block.one with Brendan and the team and there is far too much momentum behind EOS for him to possibly leave.

17. Is EOS susceptible to DDoS attacks?

 
No one could have better knowledge on this subject than our Block Producer candidates, I have chosen to look to EOS New York for this answer:
"DDoS'ing a block producing is not as simple as knowing their IP address and hitting "go". We have distributed systems engineers in each of our candidate groups that have worked to defend DDoS systems in their careers. Infrastructure can be built in a way to minimize the exposure of the Block Producing node itself and to prevent a DDoS attack. We haven't published our full architecture yet but let's take a look at fellow candidate EOSphere to see what we mean. As for the launch of the network, we are assuming there will be attacks on the network as we launch. It is being built into the network launch plans. I will reach out to our engineers to get a more detailed answer for you. What also must be considered is that there will be 121 total producing and non-producing nodes on the network. To DDoS all 121 which are located all around the world with different security configurations at the exact same time would be a monumental achievement."

18. If block producers can alter code how do we know they will not do so maliciously?

 

Quick answer:

  • Block producers are voted in by stake holders.
  • Changes to the protocol, constitution or other updates are proposed to the community by block producers.
  • Changes takes 2 to 3 months due to the fact block producers must maintain 15/21 approval for a set amount of time while for changes to be processed.
  • To ensure bad actors can be identified and expelled the block.one backed community will not back an open-entry system built around anonymous participation.
 

Long answer:

For this question we must understand the following.
  • Governance and why it is used.
  • The process of upgrading the protocol, constitution & other updates.
  • Dan’s view on open-entry systems built around anonymous participation.
 
Governance
Cryptography can only be used to prove logical consistency. It cannot be used to make subjective judgment calls, determine right or wrong, or even identify truth or falsehood (outside of consistency). We need humans to perform these tasks and therefore we need governance!
Governance is the process by which people in a community:
  1. Reach consensus on subjective matters of collective action that cannot be captured entirely by software algorithms;
  2. Carry out the decisions they reach; and
  3. Alter the governance rules themselves via Constitutional amendments.
Embedded into the EOS.IO software is the election of block producers. Before any change can be made to the blockchain these block producers must approve it. If the block producers refuse to make changes desired by the token holders then they can be voted out. If the block producers make changes without permission of the token holders then all other non-producing full-node validators (exchanges, etc) will reject the change.
 
Upgrade process
The EOS.IO software defines the following process by which the protocol, as defined by the canonical source code and its constitution, can be updated:
  1. Block producers propose a change to the constitution and obtains 15/21 approval.
  2. Block producers maintain 15/21 approval of the new constitution for 30 consecutive days.
  3. All users are required to indicate acceptance of the new constitution as a condition of future transactions being processed.
  4. Block producers adopt changes to the source code to reflect the change in the constitution and propose it to the blockchain using the hash of the new constitution.
  5. Block producers maintain 15/21 approval of the new code for 30 consecutive days.
  6. Changes to the code take effect 7 days later, giving all non-producing full nodes 1 week to upgrade after ratification of the source code.
  7. All nodes that do not upgrade to the new code shut down automatically.
By default, configuration of the EOS.IO software, the process of updating the blockchain to add new features takes 2 to 3 months, while updates to fix non-critical bugs that do not require changes to the constitution can take 1 to 2 months.
 
Open-entry systems built around anonymous participation
To ensure bad actors can be identified and expelled the block.one backed community will not back an open-entry system built around anonymous participation.
Dan's quote:
"The only way to maintain the integrity of a community is for the community to have control over its own composition. This means that open-entry systems built around anonymous participation will have no means expelling bad actors and will eventually succumb to profit-driven corruption. You cannot use stake as a proxy for goodness whether that stake is held in a bond or a shareholder’s vote. Goodness is subjective and it is up to each community to define what values they hold as good and to actively expel people they hold has bad.
The community I want to participate in will expel the rent-seeking vote-buyers and reward those who use their elected broadcasting power for the benefit of all community members rather than special interest groups (such as vote-buyers). I have faith that such a community will be far more competitive in a market competition for mindshare than one that elects vote buyers."

19. What is the most secure way to generate EOS key pairs?

 
Block producer candidates EOS Cafe and EOS New York have come forward to help the community with this topic.
The block producer candidate eosnewyork has kindly posted a tutorial on steemit detailing the steps that need to be taken to generate key pairs using the official code on the EOS.IO Github.
The block producer candidate eoscafe has gone a step further and released an Offline EOS Key Generator application complete with GUI for Windows, Linux & Mac. Not only can this application generate key pairs but it can also validate key pairs and resolve public keys from private keys. This application has also been vouched for by EOS New York

The History, The Current State And The Future Of NavCoin

The History, The Current State And The Future Of NavCoin

This is it. If you're interested to see what NAV is all about, this is the ultimate guide for you. You will learn about the history of NavCoin and how it evolved. You will learn about the current state and features of NavCoin and you will learn about the exciting new features that are planned and coming up in the (near) future.
So buckle up, this is going to be a long ride!

Table Of Content


Introduction - What is NavCoin?


The History

Introduction
The following chapter will summarize and break down the history of NavCoin in a few sentences. NAV started a long time ago, went through rebrandings and changes of the core team before it became what it is today.

SummerCoin
NavCoin was initially first introduced under the name SummerCoin on April 23 in 2014. SummerCoin was a fork of the Bitcoin blockchain. It used to have a PoW/PoS hybrid algorithm with a block time of 45 seconds.

SummerCoinV2 /NavajoCoin
Soon after the initial launch of SummerCoin, the original developer left and SoopY (soopy452000 on bitcointalk) took over as the main developer and rebranded the project to SummerCoinV2 respectively NavajoCoin and introduced new features.
The name NavajoCoin was chosen in honor of the Navajo Code Talker. The unbreakable Navajo code was used to encrypt highly classified military information and commands and decrypt the same in WW II.
SoopY introduced a technology which allowed sending transactions anonymously and private. This technology was called "Navajo Anonymous Technology". SoopY also released a new wallet and set the Proof of Stake rewards at 10% for the first year, 5% for the second year and 2% for every year after.

NavCoin
On August 12, 2014, Craig (current lead core developer, pakage on bitcointalk) started to get involved with NAV by helping to set up a website [10].
It was officially announced that Craig joined the core team as a "Wallet & Web Developer" on November 06, 2014.
The last tokenswap and restart of the blockchain of NAV happened on May 12, 2016.
Soon later, SoopY stopped showing up and Craig stepped into the role of the lead core developer. Since then, Craig has assembled a strong team with which he built NavCoin into what it is today.
Currently, Craig and the NavCoin Core team is located in New Zealand and they are actively developing many ground-braking features which differentiate NAV from other cryptocurrencies. You will read more about that later in this article.

The Current State

Introduction
The year 2018 has been a thriving year for the NavCoin ecosystem. Despite the USD price of NAV not reflecting it, in 2018 the core team has developed a whole bunch of new features. Also the core content creators published the first official guidelines that function as an orientation guide for community content creators. This chapter will give you an overview of the current team, the features, the prior mentioned guidelines and the community of NavCoin.

Core Team [1]
Last year, the core team has grown alot. It contains of developers, content creators and interns. The core team are employees of Encrypt S, the New Zealand's leading blockchain R&D lab. Encrypt S is developing blockchain solutions since 2014 and values building open-source software highly.

Craig MacGregor - Chief Executive Officer
Craig is the CEO of Encrypt S and the founder of NavCoin. He is one of the world's most experienced blockchain developers. Craig founded NavCoin in 2014 and is developing software for it since then. He has assembled a strong team of like-minded people. Craig also speaks at seminars and conferenced. Some of the companies and conferences he did blockchain education sessions at are Oracle, Xero, Air New Zealand, Blok Tex and trademe. Together with the team, he is also doing a education series on YouTube where he explains upcoming features in-depth for the community.

Alex Vazquez - Chief Technical Officer
Alex is the CTO of Encrypt S and the most active contributor to the NavCoin core Github. He has incredible knowledge of blockchains and proposes and implements solutions for challenges and features. He supports community developers frequently and answers any questions of the community thoroughly. Like Craig, Alex is developing software for the NavCoin ecosystem for a very long time. Alex speaks at universities at times and educates students about the blockchain technology.

Paul Sanderson - Lead Software Engineer
Paul is the Lead Software Engineer at Encrypt S. He has a flair for technology. His technical and management skills are perfectly suited for consultancy and investment advising. He also frequently contributes to the NavCoin core source code.

Rowan Savage - Senior Software Engineer
Rowan is a full stack software engineer with more than a decade experience in developing complex front-end web applications. He joined Encrypt S in February 2018 and has since been involved in the Valence Plattform, the Kauri Wallet and NavCoin Core. You will read more about these feature/projects later.

Carter Xiao - Lead UX/UI Designer
Carter specializes in user-centric design and is also very talented with 3D animation, motion graphics and programming. One of NavCoins core principle is "Simplifying Crypto" and UX/UI is a very important part of that.

Matt Paul - Software Engineer
Like Rowan, Matt is a full stack Software Engineer. He joined the core team in Mai 2017 and has since worked on NavPay, NavPi, the Kauri Wallet and NavCoin Core. Kieren Hyland - Chief Strategy Officer Kieren is one of the employees that are working for Encrypt S for a very long time. He is the CSO and is a digital strategist and growth hacker with a passion for new technology and has a lot of experience in online marketing. Laura Harris - Creative Director Laura has a combination of commercial and creative flair. She manages the social media accounts for NavCoin and ensures, that NavCoins' message is always powerful, relevant and distinctive. John Darby - Content Creator John is an internationally awarded Technology and Financial sector marketing communications specialist. He is one of the Core Content Creators for NavCoin.

Features of NavCoin [2]
The following features are currently available and have been developed in the last months and years. It is sorted from newest to oldest.

Static Block Reward
The soft-fork for the enabling of static block rewards have been accepted and became active recently at 5th January 2019. This means, that the block reward was changed from a percentage based reward to a static reward. This will incentivize the stakers to have their node online 24/7 which increased the security of the network. It also aligns NavCoin with the PoSv3 specification. With this implementation, the yearly inflation will be 3.6% currently and will exponentionally decrease because of the static value of the rewards. Every staked block will now give the staker 2 NAV. Depending on how many people are staking, the yearly percentage varies. With the network weight currently being around 20'000'000 NAV, stakers earn around 10% rewards from staking 24/7.

Cold staking
To provide extra security to participants in the staking process in the NavCoin network, the core team decided to implement cold staking. This allows to store NAV offline and still be able to sign staking inputs. Looking forward, a possible integration into the Ledger Nano S would mean, that one can stake NAV securely from a offline hardware wallet. How cool is that?

OpenAlias
One of the core principle of NAV is to simplify cryptocurrencies. Many non-technical people are deterred from the long, cryptic addresses used in wallets. When sending funds, you have to make sure that every single letter and digit is correct which is nerve-wracking for the average person. NavCoin has implemented OpenAlias, which allows to transform the wallet address into a email-like form. Everyone can register a name like "[[email protected]](mailto:[email protected])". Funds can then be sent to this name, which makes sending crypto much easier and less error-prone.

Community Fund
This is the one big feature I was most excited about. NavCoin core has implemented the first fully decentralized community fund. Acceptance of proposals and release of funds is all approved by the decentralized network. No central authority has access to the fund. The community fund enables everyone to propose their ideas to the NavCoin community and to get paid to implement these ideas. Everyone can propose whatever they like (of course there is a higher rate of success if the proposal contributes to the NavCoin ecosystem ;-)). In fact, this article was sponsored by the NAV-Community by voting "yes" for my proposal. The fund works like this:
For a fee of 50 NAV, everyone can create and present his idea/proposal to the entire NavCoin network. The fee is here to help prevent spam attacks. Proposals can literally be anything - be it development, marketing or anything else you can some up with.
After creating the proposal, everyone contributing to the NavCoin network can then decide if they like the proposal of not. They vote with "Yes" or "No" for the acceptance of the proposal. Voting happens via staking. Every transaction that gets validated by you gives you one vote. This means that the more NAV you are staking, the higher your voting weight is.
The proposal stays in the state "Pending" until it is accepted or rejected. To be accepted, a proposal has to have a participation of at least 50% of all staked blocks and at least 75% of these votes have to be "Yes"-votes. Like-wise to be rejected a proposal need 50% participation of the network and 75% of these votes have to be "No"-votes. Additionally, if a proposal didn't pass after 6 voting cycles (about 6 weeks) it is also rejected.
After a proposal has been accepted, the creator of the proposal can start his work. When the work is finished, or at in the proposal defined checkpoints, the proposal creator can create a payment request for the full or part of the requested funds.
The NavCoin network can then again decide, if the work is what the creator promised to do and vote for the funds or reject the payment request because it was not what he promised. This mechanism ensures, that the funds are only release if the creator of the proposal did what he promised. The NavCoin network decides everything, there is no central authority which makes the community fund 100% decentralized.
The community fund is quite new but there have already been some proposals that were accepted like paying for the development & hosting of NAV block explorer, the creation and distribution of NAV car stickers to the community for free (or paid by the community fund), the funding of interns for NavCoin Core, translation of the website into other languages and YouTube videos. What ideas could you come up with? By the way: this article was also sponsored by the community fund :-)

Proof of Stake
Like said before, NavCoin uses the Proof of Stake algorithm to create and validate blocks. Participants of the NavCoin network can earn rewards by putting their coins to stake and thus validating blocks and securing the network. The reward used to be 4% fixed but recently changed with the implementation of PoSv3. Currently, rewards for stakers that are staking 24/7 is about 10% but it is dependent on how many people are staking. If more nodes come online, this reward will go down. If 90% of all NAVs would be at stake, stakers would still earn 4%.

Tutorials And Guidelines [3]
The NavCoin Core team pushes the community to contribute to the NavCoin ecosystem constantly. They emphasize that NavCoin is an open source project and everyone can contribute. The team tries to make it as easy as possible for the average person to contribute and thus created different tutorials and guidelines.

Tutorials To Contribute To The Website
The whole website is open source. Everyone can contribute to the website. The team created different guides for people to follow [4].

The NavCoin Developer Manifesto
The content creator core team has build a developer manifesto. It defines the values that should be uphold like for example that they will always operate in the best interest of the network. If defines the principles, purposes, scope of involvement and operational requirements [5].

The NavCoin Content Creation Manifesto
Similar to the developer manifesto, there is also a content creation manifesto. Again it defines the principles for creating content, the purpose, the scope of involvement and the operational requirements [6].

NavCoin Brand Guidelines
In addition to the content creation manifesto, there is also a brand guideline booklet. This should help content creators to create images, videos, articles etc. in the same style as the core team. It defines the NAV brand. The brand guidelines contain definitions, the language to use (words to use, words not to use), the tone of voice, what the community aspires to be and what we discourage to be. It also contains the logo pack which can be used in graphics etc. It describes correct logo spacing, logo placement, the colors of NAV and different web assets. It gives tips about gradients and overlays, the typefaces (with a font pack) and many more. Check it out yourself [7].

NavCoin Educational Series
The core team has decided to actively involve the community in the creation of new features. For this reason and to allow users to ask questions, they created the NavCoin Educational Series. The core team schedules an online live meetup which can be joined by everyone. On YouTube they do live-streams and explain upcoming features. Examples of these series are explanations for cold staking, static rewards (PoSv3) and the community fund. The community can ask questions live and the core team will answer them immediately.

Community
During the last year there have been an influx of software developers from the community starting to create features for NAV.

navexplorer.com
An examples is navexplorer.com which is programmed by community developer prodpeak and is a block explorer for NavCoin. Additionally, it functions as a interface to see what is going on in the community fund. It shows pending proposals and payment requests.

NEXT Wallet
The NEXT Wallet is an alternative wallet for NAV and other cryptocurrencies. It has a beautiful user interface and is additionally the easiest interface to interact with the community fund (create proposals, create payment requests and vote for proposals and payment requests). It is programmed by community developer sakdeniz who put hundreds of hours into it during last year.

There were also some marketing activities starting to emerge with the release of the community fund. Some of these were for example free stickers for everyone in the NAV community to stick to their car / shop / window etc. or YouTube videos of CryptoCandor and Cryptomoonie that explained the details of NAV. I am sure, that with the 500'000 NAV available in the community fund per year there will be an influx of gread ideas - development as well as marketing activities - that will be funded.

The Future

Introduction
These features are planned for the future. Many of the following features are part of the 2019 roadmap. Some will not be described in great detail because not much is known about them yet. I've still listed them as they are part of what is yet to come.

Features
Rimu - Improved Privacy Solution
NavCoin used to be a optional privacy coin. That means, that you could choose to send a transaction in private. NavCoin was criticized for the way it handles private payments because it relied on a few servers which didn't make it that decentralized. The technology was called "NavTech" and was a secondary blockchain that obscured the transaction and the amount that was sent. NavCoin Core is currently developing a new improved privacy solution that will make the private payment system completely trustless and districuted and runs at a protocol level. Alex of the NavCoin Core team has published a paper that describes this new privacy solution. It's called Zero Confidential Transactions and can be found here: https://www.researchgate.net/publication/330366788_ZeroCT_Improving_Zerocoin_with_Confidential_Transactions_and_more. What I want to highlight is the collaboration between Alex as the proposer of the solution and the Veil team, a Bitcoin Core developer and Moneros main cryptographer as reviewers. When the best work together, it will be interesting to see what the outcome is!

Valence Plattform [8]
Valence is an applied Blockchain platform that can help businesses realise the tangible benefits of blockchain. You can think of Valence as a platform with which you can build Anonymous Distributed Applications (aDapps) with. But Valence is a different kind of platform that enables developers to create new types of blockchain applications. The problem with current (turing complete) dApp platforms are their complexity and rigid nature. Security holes in smart contracts and scaling issues happen frequently [9].
Valence provides transitional pathways that let businesses migrate only part of their activities to the blockchain without having to restructure their entire business model [9].
Valence will provide a spectrum of blockchain application solutions which sit along the decentralized spectrum, offering businesses simple ways to dip their toes into the blockchain at minimal risk or complexity [9].
Thanks to the proof of stake nature of the Valence blockchain, more of a node's resources can be used for processing and routing application data which makes the platform faster and scalable.
Valence aims to make building blockchain applications as accessible to the general public as WordPress or Squarespace has made building websites.
The developers NavCoin and Valence aim to make Valence extremely easy to work with:
A Valence application could be an open source mobile or web application that submits unencrypted or encrypted data directly to the blockchain. The only configuration necessary for the app developer would be setting up the data structure. Once they've done that they can start writing to the blockchain immediately.
The Valence blockchain interface is language agnostic, meaning developers are free to build applications in whichever language they're familiar with, which greatly reduces the barrier to entry.
As the platform progresses, Valence will introduce more and more smart contract templates in collaboration with the development community. These will be like plugins that users can simply select and configure for their application, without having to reinvent the wheel and risk contract errors or spend countless hours of research to program them.

NavShopper
The following information is taken from the latest weekly news: NavShopper is a new project which will allow people to spend NavCoin on a growing list of retailers and service providers. NavShopper sits between traditional retailers accepting fiat and NavCoin users and purchases products on behalf of the user by managing the crypt-fiat conversion, payment and shipping. This project will unlock many more ways for people to spend NAV on existing websites/marketplaces without requiring each site to individually accept cryptocurrencies. Some of the prototypes we are working on include crediting your Uber account, buying products on Amazon and donating to charities.

Kauri Wallet
The Kauri Wallet aims to be an open-source, multi-currency wallet which functions as a foundation for other features.

Kauri Enhanced
Enhancements to the Kauri Wallet will allow multiple accounts, pin numbers, recurring payments and more.

Kauri DAEx
The Kauri DAEx is a Decentralised Atomic Exchange that utilises the features of the Kauri Wallet and enables users to create safe peer to peer atomic exchanges for any currency supported by the Kauri Wallet. NavDelta NavDelta will be a payment gateway that allows users to spend NAV at any business which accepts currencies supported by the Kauri Wallet. NavMorph NavMorph is a fusion of Rimu and Kauri DAEx and will allow to privately send every cryptocurrency supported by the Kauri Wallet.

Outro

If you have made it this far: Congratulations! You have learned about how NAV evolved, what its current state is and what the future will bring. To sum all up: NavCoin has made incredible progress during last year and released many long awaited features despite the bear market. Many more exciting features are yet to come and it's going to be very interesting to see where we will stand on this day next year.

Giveaway

Unfortunately, the giveaway was not possible in the cryptocurrency-subreddit because of their rules, so I'm doing it here :-) As a surprise, in the next 2 hours I am going to send some NAV to everyone who wants to try out the awesome features and NavPay you read about above.
To get your NAVs, all you have to do is the following:
If you liked the experience, I'd be happy to hear back from you :)
