‎Binance: Buy Bitcoin Securely on the App Store

Ethereum Classic

Ethereum Classic is an open, decentralized, and permissionless public blockchain, that aims to fulfill the original promise of Ethereum, as a platform where smart contracts are free from third-party interference. ETC prioritizes trust-minimization, network security, and integrity. All network upgrades are non-contentious with the aim to fix critical issues or to add value with newly proposed features; never to create new tokens, or to bail out flawed smart contracts and their interest groups.

Careful with Binance Mac desktop app

This thing is super buggy with the last update. I went to put a stop loss in and the chart was correct but then i got a warning about the stop loss being triggered immediately because the price was already that low. Then i noticed the bid and ask lists were right but the price showing between them was wrong, the % change above the chart also showed -1% instead of being up 14% which was the reality.
Basically if i had market sold, which i don’t do it seem it would have sold my coins for 15% less than their current value.
So be cautious with that app. It’s been problematic since the last update. Yesterday the charts were double posting candles and previous candles were vibrating and changing which obviously shouldn’t happen.
Just a heads up.

NanoVault/NinjaVault balance shown as 0, also transaction listed as pending for over 3 months now

Hey everyone, I've been using the NanoVault app for mac in conjunction with NinjaVault online and my Ledger Nano to store my NANO. The problem I'm encountering right now is when I open up NanoVault, my balance is listed as 0/$0.00 in the top left corner. When I click on the account in the accounts tab it does show all of my recent transactions, but it just seems very buggy...also a transaction from binance is greyed out with an asterisk (denoting that it is pending). This withdrawal was made in February. Has anyone encountered these problems and found solutions, or have any better alternatives to wallets that are integrated with the Ledger Nano? I've also bought some more NANO in the past few days and would like to send it over to my wallet from binance, but I'm kind of nervous that something is messed up and would prefer not to lose the NANO in the process.
I've tried pressing the refresh icon next to representative (to change to a suggested representative), then on my ledger I press 'confirm block' but nothing happens...the transaction from February is still listed as pending. In the past I've had problems with the mac NanoVault app displaying the balance but NinjaVault seemed to always be more accurate. Now I'm not sure how to proceed. Any help would be appreciated.

About ARPA

ARPA is a blockchain-based solution for privacy-preserving computation, enabled by Multi-Party Computation (“MPC”). Founded in April 2018, the goal of ARPA is to separate data utility from ownership, and enable data renting. ARPA’s MPC protocol creates ways for multiple entities to collaboratively analyze data and extract data synergies, while keeping each party’s data input private and secure. ARPA allows secret sharing of private data, and the correctness of computation is verifiable using information-theoretic Message Authentication Code (MAC).
Developers can build privacy-preserving dApps on blockchains compatible with ARPA. Some immediate use cases include: credit anti-fraud, secure data wallet, precision marketing, joint AI model training, key management systems, etc. For example, banks using the ARPA network can share their credit blacklist with each other for risk management purposes without exposing their customer data or privacy.
Team members have worked at leading institutions such as Google, Amazon, Huawei, Fosun, Tsinghua University, Fidelity Investments. ARPA is currently assisting the China Academy of Information and Communications Technology in setting the national standard for secure multi-party computation. ARPA is a corporate member of MPC Alliance and IEEE and is in partnership with fortune 500 companies to implement proof-of-concepts and MPC products. In 2019, ARPA was named as the Top 10 most innovative blockchain companies in China by China Enterprise News and China Software Industry Association.

Margin Trading with MacOS Desktop App / Lag and order history update bug

Hi,
I have 3 questions for which I couldn't find a clear and official answer so far, so I think it might be useful for other people trading on Binance :
Q1. Is it normal that I cannot see anything related to Margin Trading in the v1.2.21 Desktop App for Mac OS ? I am not speaking about the iOS App here, but the DESKTOP App.
Q2. Do you plan to update this desktop App one day or did you give up with it and I should only use the web interface or API to trade margin on Binance ?
Q3. What is the best configuration (= which Browser under Mac os) to get the best experience when using your web interface ? The order history has A LOT of bugs and show wrong data 80% of the time because it does not update properly, not mentioning the fact that the whole web interface is super super slow (I have no Add blocker plugIn and use Chrome right now...).
Thank you for your work, and for your help !

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.

About ARPA

ARPA is a blockchain-based solution for privacy-preserving computation, enabled by Multi-Party Computation (“MPC”). Founded in April 2018, the goal of ARPA is to separate data utility from ownership, and enable data renting. ARPA’s MPC protocol creates ways for multiple entities to collaboratively analyze data and extract data synergies, while keeping each party’s data input private and secure. ARPA allows secret sharing of private data, and the correctness of computation is verifiable using information-theoretic Message Authentication Code (MAC).
Developers can build privacy-preserving dApps on blockchains compatible with ARPA. Some immediate use cases include: credit anti-fraud, secure data wallet, precision marketing, joint AI model training, key management systems, etc. For example, banks using the ARPA network can share their credit blacklist with each other for risk management purposes without exposing their customer data or privacy.
Team members have worked at leading institutions such as Google, Amazon, Huawei, Fosun, Tsinghua University, Fidelity Investments. ARPA is currently assisting the China Academy of Information and Communications Technology in setting the national standard for secure multi-party computation. ARPA is a corporate member of MPC Alliance and IEEE and is in partnership with fortune 500 companies to implement proof-of-concepts and MPC products. In 2019, ARPA was named as the Top 10 most innovative blockchain companies in China by China Enterprise News and China Software Industry Association.

binance info

On Binance you can only deal with coins, no cash. So what do you all do... you send them to another wallet that allows cash withdrawls. And you have to pay the fees for that...what do you do and why...? also is there a way now in 2020 to copy the crypto address on your MAC and paste it onto your phone cryto app screen?? I would rther NOT use the camera. I blocked mine with tape.

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

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

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

What is a blockchain Operating system?

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

How is Overledger different to other interoperability projects?

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

https://preview.redd.it/xew1eu1exel31.png?width=1558&format=png&auto=webp&s=df960ded46d40fc9bf0ae8b54ff3b3b86276708a
Other solutions require every connecting blockchain to fork their code and implement their Interoperability protocol. This means the same type of connector can be used instead of a custom one for every blockchain however every connected blockchain has to fork their code to implement the protocol. This enforces a lot of restrictions on what the connected blockchains can implement going forward.

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

But some Interoperability blockchains say they are infinitely scalable?

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

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

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

Overledger’s approach

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

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

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

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

Patents

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

Multi Chain Applications (MAPPs)

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

Treaty Contracts

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

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.

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

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

What is a blockchain Operating system?

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

How is Overledger different to other interoperability projects?

Other projects are trying to achieve interoperability by adding another blockchain on top of existing blockchains. This adds a lot of overhead, complexity, and technical risk. There are a few variants but essentially they either need to create custom connectors for each connected blockchain and / or require connected chains to fork their code to enable interoperability. An example of the process can be seen below:
User sends transaction to a multi sig contract on Blockchain A, wait for consensus to be reached on Blockchain A
A custom connector consisting of Off Chain Relay Nodes are monitoring transactions sent to the smart contract on Blockchain A. Once they see the transaction, they then sign a transaction on the Interoperability blockchain as proof the event has happened on Blockchain A.
Wait for consensus to be reached on the Interoperability Blockchain.
The DAPP running on the Interoperability Blockchain is then updated with the info about the transaction occurring on Blockchain A and then signs a transaction on the Interoperability blockchain to a multi sig contract on the Interoperability Blockchain.
Wait for consensus to be reached on the interoperability Blockchain.
A different custom connector consisting of Off Chain Relay Nodes are monitoring transactions sent to the Smart Contract on the Interoperability Blockchain which are destined for Blockchain B. Once they see the transaction, they sign a transaction on Blockchain B. Wait for consensus to be reached on Blockchain B.
https://preview.redd.it/2apm3pb5wel31.png?width=1558&format=png&auto=webp&s=7027514706d7b12690b1be8f4f4af7cfc9c43354
Other solutions require every connecting blockchain to fork their code and implement their Interoperability protocol. This means the same type of connector can be used instead of a custom one for every blockchain however every connected blockchain has to fork their code to implement the protocol. This enforces a lot of restrictions on what the connected blockchains can implement going forward.

https://preview.redd.it/4axzxx57wel31.png?width=1561&format=png&auto=webp&s=a8c3de8468ef9b67bc1db75cffbef81ef8c0aa70
Some problems with these methods:
  • They add a lot of Overhead / Latency. Rather than just having the consensus of Blockchain A and B, you add the consensus mechanism of the Interoperability Blockchain as well.
  • Decentralisation / transaction security is reduced. If Blockchain A and Blockchain B each have 1,000 nodes validating transactions, yet the Interoperability Blockchain only has 100 nodes then you have reduced the security of the transaction from being validated by 1000 to validated by 100.
  • Security of the Interoperability Blockchain must be greater than the sum of all transactions going through it. JP Morgan transfer $6 Trillion every day, if they move that onto blockchain and need interoperability between two Permissioned blockchains that have to connect via a public Interoperability blockchain, then it would always have to be more costly to attack the blockchain than the value from stealing the funds transacted through the blockchain.
  • Imposes a lot of limitations on connected blockchains to fork their code which may mean they have to drop some existing functionality as well as prevent them from adding certain features in the future.
  • Creates a single point of failure — If the Interoperability blockchain or connector has an issue then this affects each connected blockchain.
  • It doesn’t scale and acts as a bottleneck. Not only does building complex custom connectors not scale but the Interoperability blockchain that they are forcing all transactions to go through has to be faster than the combined throughput of connected blockchains. These Interoperability blockchains have limited tps, with the most being around 200 and is a trade off between performance and decentralisation.

But some Interoperability blockchains say they are infinitely scalable?

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

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

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.
