"The website only shows transactions from the last 7 days and then they disappear. No way for anyone to access stats beyond that." (source)he felt confident to claim that I would be

Bitcoin options are breaking records, and exchanges are competing for this segment. We will tell you what these tools are and how they worksubmitted by Smart_Smell to Robopay [link] [comments]
The cryptocurrency market is constantly evolving, integrating with the traditional and inheriting complex financial products such as futures and options.
Some types of fixed-term contracts are already firmly established in the bitcoin industry. This is noticeable by the activity of traders on the CME.
However, the situation with options is somewhat different. These derivatives are difficult to understand among ordinary market participants and are not yet so popular.
Nevertheless, there is a demand for such tools, as evidenced by the growth dynamics of this market segment and interest from platforms such as Binance and Bitfinex.
Bitcoin options have already been offered on CME, LedgerX and Bakkt, which are regulated and oriented primarily on whales. Among the unregulated sites, the leader is Deribit, followed by FTX and OKEx.
ForkLog magazine figured out what options are and what types of options are. We will talk about the features of these tools and the current state of affairs in the segment. In this article you will also find comments by leading market experts on the role of options in the industry.
What are options and how do they work?An option is a financial contract concluded between two parties — the holder and the seller. The first receives the right, but not the obligation, to buy or sell a certain amount of the underlying asset at the strike price (strike price) on a specific date (expiration date).
The seller undertakes to buy or sell the asset at the request of the option holder. The latter pays the seller at the time of purchase of the contract a certain amount of money — the so-called premium.
The rights and obligations of the holder and seller differ significantly. The former has the right to choose whether to exercise the option or not. The seller is obliged to fulfill the terms of the contract at the request of the holder.
Parameters such as the type of underlying asset, expiration date, strike price are fixed at the time of issue of the contract, after which they cannot be changed.
Like futures, options are derivative financial instruments and derivatives. This means that they can be based on various underlying assets (BA) — stocks, indices or cryptocurrencies.
“Like the options already existing in traditional finance for all major assets, there are contracts based on BTC and ETH on the cryptocurrency market. They are very interesting financial products“, said Su Zhu, head of Three Arrows Capital, in a conversation with ForkLog.
Options are used both for hedging risks and for speculative trading. For example, a speculator confident in the growth of the underlying asset buys a call option. If the BA price rises above the strike, the trader can use his contract to buy a discounted asset.
“Derivatives such as options allow users to hedge risks and generate revenue. Derivatives play a key role in the traditional financial market. These tools are needed so that the cryptocurrency market continues to grow and develop, being filled with new participants“, said Aaron Gong, vice president of Binance Futures.
Practical use of optionsConsider the simplest example of options hedging. Suppose there is a company manufacturing tomato paste, sauces and ketchups. There is a farmer supplying this company with tomatoes. He acts in conditions of fierce competition, close to perfect.
It is extremely important for a company to buy raw materials cheaper to minimize production costs and remain profitable. The farmer, in turn, hopes for a long-term cooperation with the company so as not to lose a major client.
The company offers the farmer an option, assuming the right to buy 10 tons of tomatoes of the next year’s crop at the current price — say, $1,000 per ton. To exercise this right, the company pays the farmer an option premium of 3% of the total transaction amount of $10,000, that is, $300.
The farmer will have to, at the request of the company, sell the appropriate quantity of goods at the above price and at a specified time.
A year later, the crop was high, which led to a decrease in the market value of tomatoes to $800 per ton. The company decides not to exercise its right to purchase raw materials for $10,000, as other farmers can buy the same 10 tons of tomatoes for only $8,000.
Thus, having lost only $300 as a premium on an option, the company is insured against price risk. Buying raw materials at a significantly lower market price is more than worth the price of the option contract.
Let’s imagine another scenario: the crop turned out to be unimportant and the price of scarce tomatoes jumped to $1200 per ton. Then the company will certainly take advantage of the right to purchase tomatoes for $1000. Thus, the result is any case.
It is easy to guess that the options can be used by miners to hedge the risks of adverse changes in the price of the extracted asset. For example, expecting a decrease in the price of BTC, miners can use options that give them the right to sell cryptocurrency in the future at a price higher than the breakeven point.
“Miners are already very active in options markets. And, probably, they will remain active“, Su Zhu said.
Su Zhu is confident that in the long term, options will make the cryptocurrency spot market more liquid and attractive to a wide range of participants. He added that the growing popularity of such contracts among miners could significantly reduce sales pressure.
“Options give miners the opportunity to fix the price of coins mined in the future. Miners can better manage their production costs and protect themselves from market volatility“, said Aaron Gong, expressing confidence that the popularity of options will continue to grow.
According to him, such tools open up new opportunities and may be of interest to speculators, funds and long-term cryptocurrency holders.
“Institutional investors are also showing growing interest in options and other derivatives. Last week it was reported that the famous Wall Street trader Paul Tudor Jones allocated a few percent from his Tudor BVI fund for bitcoin futures. This is a positive signal, which means that more and more institutions are interested in the cryptocurrency market“, Gong added.
However, option strategies are not suitable for every market participant — effective work with these tools requires certain experience, Co-founder of CoinIndex.agency Julia Sporysh is sure:
“Of course, in order to use this effectively, the miner must have an experienced trader (option strategies are some of the most difficult on the market) — or they will have to unite and work through specialized trading companies. This market exists, although it is not for the general public.”
Also, according to her, options may be of interest to funds and retail traders who have gained a hand in speculative trading.
“Options are an independent and good speculative tool. And if you have positions in futures or in the spot market, it’s just the time to explore new opportunities“, added Yulia Sporysh.
Types of optionsThere are two main types of options — option call and option put. The first gives the right to the contract holder to purchase a certain amount of the underlying asset from the seller (they also say — the inscription) at the strike price on a certain date in the future. This type of option was used in the tomato example.
The put option, on the contrary, gives the buyer of the contract the right to sell the underlying asset at a fixed price. The latter may be higher than the market at the time of expiration, which is beneficial to the trader.
Market participants use the call, predicting an increase in the price of BA, and put — expecting it to decline.
More complex strategies use combinations of these two types of contracts.
There is also the term “covered option”. For example, an option call is covered if the seller has the amount of the underlying asset corresponding to the terms of the contract.
Options may also differ in the style of execution — American or European.
European-style options require the holder to execute the contract exclusively on the expiration date. Such options, in particular, are presented at CME and Bakkt.
American style implies the possibility of contract execution at any time prior to the date of expiration. Options of both styles are traded all over the world, their names have no relation to geographic location.
There are less standardized, exotic options. However, the popularity and importance of such instruments in the financial market is not so great.
Parameters and conditions for trading certain options are described in the specifications for them, which indicate the expiration date, strike price and other elements of the contract.
Premium, strike price and cash optionThe option premium is the amount of money paid by the buyer to the seller. The premium is equal to the value of the contract and, in fact, represents a fee for the risk of adverse changes in the value of the underlying asset.
The option premium is formed by two components:
• Intrinsic value — the amount that the buyer would receive if the contract were currently executed. It depends on the ratio of the price of the underlying asset and the strike.
• Time value — depends on the time remaining until expiration. Usually, the less time it takes to execute a contract, the lower the premium.
As a rule, high price volatility contributes to premium growth, and vice versa. A deal with a close strike price in relation to the current one has much greater chances of closing in profit and, therefore, the premium for such an option will be relatively high.
The strike price is the price fixed in the option at which the buyer of the call option can buy (or sell, if this is a put option) the underlying asset. In turn, the seller of the contract is obliged to sell or buy BA.
Money is an indicator of the ability to receive funds from the exercise of the right to exercise a derivative. In the context of options, cash can be calculated by comparing the spot price of the BA and the strike price of the option. Thus, three options are possible:
• “in the money” option: in the case of a call — if the spot price is higher than the strike (then the intrinsic value of the contract is positive), in the case of a put, on the contrary, if the BA price is lower than the strike;
• option “on money” (or “with one’s own”) — equal strike to current stock quotes, intrinsic value equal to 0;
• the option “out of money” (“without money”) — the exercise of the option is not economically feasible; in such a situation, the current price of the underlying asset is lower than the strike price of the call option or, conversely, the spot price of the BA is higher than the strike price in the case of a put.
Option strategiesThere are many option trading strategies. Four basic approaches can be distinguished.
Long call — buying a call option, the investor expects an increase in the price of the underlying asset above the strike on the expiration date of the contract. Then he will be able to buy an asset at a discount to the market price and thus earn on the difference. If the price drops below the strike, the buyer risks only the premium paid for the option.
Long put — is a kind of alternative to a short position in the spot market. The buyer of the put option hopes to make money, assuming that the price of the BA falls below the strike at the time of expiration. In this scenario, the investor may sell the asset at a higher price than the market price.
Also, through a put option, an investor can limit the risk of a fall in the price of an asset that has a long position open. According to Su Zhu, miners may use the “protective put” strategy, in whose activity a substantial and prolonged drop in the price of mined cryptocurrency is undesirable. Through such tools, miners can provide profitable or even break-even activity.
Short call — the investor acts as the seller of the contract, counting on a decrease in the price of BA below the strike on the date of expiration. However, the higher the price of the asset, the more losses the inscription bears. Thus, the risk of the seller of the contract is unlimited, and the profit potential is limited by the premium on the sale of the call.
Short put — the seller of such an option expects a premium on it, being firmly convinced that the price of the BA will be higher than the strike.
Combinations of these basic strategies may underlie more sophisticated options trading approaches, such as:
• protective put — purchase of a put option for an available asset;
• covered (secured) call — an investor sells a call option to an existing BA or which will be acquired simultaneously with the sale of the option; the strategy reduces the risk of owning an asset, since a fall in its price is partially offset by a premium;
• straddle — a kind of bet on volatility, which implies the purchase of a call and put option on the same asset with the same expiration date and the same strike price;
• strangle — almost the same as straddle, differs only in different strike prices.
ConclusionsOptions are complex financial instruments, their mechanism of work is unlikely to be mastered immediately by most novice traders. Nevertheless, these derivatives may seem interesting to experienced market participants and, in particular, to miners.
The following advantages and disadvantages of options can be distinguished. Of the advantages of these contracts, we note:
- flexibility of use in speculative trading;
- the ability to use many combinations and trading strategies;
- a good tool for hedging risks;
- the ability to use in any trend — upward, downward, sideways.
- the difficulty of understanding the mechanism of work, especially for novice market participants;
- asymmetric conditions and, accordingly, risks for the buyer and seller;
- the complexity of trading strategies;
- the volatility of an option premium, which depends on the proximity of the expiration date and price dynamics in the spot market;
- low liquidity.
Different industry players have different cryptocurrency options. Some consider them promising tools useful for miners, funds, retail traders and the market as a whole. Others are convinced that such derivatives are archaism.
Nevertheless, options are gradually taking root in the cryptocurrency market. This is evident in the dynamics of trading volume and open interest. In addition, more and more exchanges are trying to add support for these contracts, which contributes to increased competition and further development of the industry.

To enter or exit the crypto economy, we rely on centralized exchanges such as Coinbase, which track their users, impose limits, and are tightly coupled to their jurisdiction and its banking system. And for all we know, any day now regulations could start tightening these controls further (*we've actually seen some of this play out in the two months since our first launch post). In light of this, can we say in any meaningful sense that crypto is anonymous, limtiless, borderless, immune to regulation, and (most importantly) unstoppable?To really address this concern, we need a completely decentralized gateway between fiat and crypto: something that extends the benefits of crypto to the very act of moving between the old and new economies. But the design of such a platform is far from obvious.
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.submitted by xSeq22x to QuantNetwork [link] [comments]
In less than 10 months since launching Overledger they have provided interoperability with the full range of DLT technologies from all the leading Enterprise Permissioned blockchains such as Hyperledger, R3’s Corda, JP Morgan’s Quorum, permissioned variants of Ethereum and Ripple (XRPL) as well as the leading Public Permissionless blockchains / DAGs such as Bitcoin, Stellar, Ethereum, IOTA and EOS as well as the most recent blockchain to get added Binance Chain. In addition, Overledger also connects to Existing Networks / Off Chain / Oracle functionality and it does all of this in a way that is hugely scalable, without imposing restrictions / requiring blockchains to fork their code and can easily integrate into existing applications / networks by just adding 3 lines of code.
What is a blockchain Operating system?You will be familiar with Operating systems such as Microsoft Windows, Apple Mac OS, Google’s Android etc but these are all Hardware based Operating Systems. Hardware based Operating Systems provide a platform to build and use applications that abstracts all of the complexities involved with integrating with all the hardware resources such as CPU, Memory, Storage, Mouse, Keyboard, Video etc so software can easily integrate with it. It provides interoperability between the Hardware devices and Software.
Overledger is a Blockchain Operating System, it provides a platform to build and use applications that abstracts all of the complexities involved with integrating with all the different blockchains, different OP_Codes being used, messaging formats etc as well as connecting to existing non-blockchain networks. It provides interoperability between Blockchains, Existing Networks and Software / MAPPs
How is Overledger different to other interoperability projects?Other projects are trying to achieve interoperability by adding another blockchain on top of existing blockchains. This adds a lot of overhead, complexity, and technical risk. There are a few variants but essentially they either need to create custom connectors for each connected blockchain and / or require connected chains to fork their code to enable interoperability. An example of the process can be seen below:
User sends transaction to a multi sig contract on Blockchain A, wait for consensus to be reached on Blockchain A
A custom connector consisting of Off Chain Relay Nodes are monitoring transactions sent to the smart contract on Blockchain A. Once they see the transaction, they then sign a transaction on the Interoperability blockchain as proof the event has happened on Blockchain A.
Wait for consensus to be reached on the Interoperability Blockchain.
The DAPP running on the Interoperability Blockchain is then updated with the info about the transaction occurring on Blockchain A and then signs a transaction on the Interoperability blockchain to a multi sig contract on the Interoperability Blockchain.
Wait for consensus to be reached on the interoperability Blockchain.
A different custom connector consisting of Off Chain Relay Nodes are monitoring transactions sent to the Smart Contract on the Interoperability Blockchain which are destined for Blockchain B. Once they see the transaction, they sign a transaction on Blockchain B. Wait for consensus to be reached on Blockchain B.
Other solutions require every connecting blockchain to fork their code and implement their Interoperability protocol. This means the same type of connector can be used instead of a custom one for every blockchain however every connected blockchain has to fork their code to implement the protocol. This enforces a lot of restrictions on what the connected blockchains can implement going forward.
Some problems with these methods:
But some Interoperability blockchains say they are infinitely scalable?If the interoperability blockchain is limited to say 200 tps then the idea is to just have multiple instances of the blockchain and run them in parallel, so you benefit from the aggregated tps, but just how feasible is that? Lets say you want to connect Corda (capable of 2000+ tps) to Hyperledger (capable of up to 20,000 tps with recent upgrade). (Permissioned blockchains such as Hyperledger and Corda aren’t one big blockchain like say Bitcoin or Ethereum, they have separate instances for each consortium and each is capable of those speeds). So even when you have just 1 DAPP from one consortium that wants to connect Corda to Hyperledger and use 2000 tps for their DAPP, you would need 100 instances of the Interoperability blockchain, each with their own validators (which maybe 100–200 nodes each). So, 1 DAPP would need to cover the costs for 100 instances of the blockchain and running costs for 10,000 nodes…This is just one DAPP connected to one instance of a two permissioned blockchains, which are still in the early stages. Other blockchains such as Red Belly Blockchain can achieve 440,000 tps, and this will surely increase as the technology matures. There is also the added complexity of then aggregating the results / co-coordinating between the different instances of the blockchain. Then there are the environmental concerns, the power required for all of these instances / nodes is not sustainable.
It’s not just transactions per second of the blockchain as well, its the latency of all these added consensuses along the path to reach to the destination and not knowing whether the security of each of the hops is sufficient and can be trusted. To see examples of how this potential issue as well as others effect Cosmos you can see my article here. I recommend also reading a blog done by the CEO of Quant, Gilbert Verdian, which explains how Overledger differs here as well as detailed in the whitepaper here.
Overledger’s approachIn 1973 Vint Cerf invented the protocol that rules them all: TCP/IP. Most people have never heard of it. But it describes the fundamental architecture of the internet, and it made possible Wi-Fi, Ethernet, LANs, the World Wide Web, e-mail, FTP, 3G/4G — as well as all of the inventions built upon those inventions.
Wired: So from the beginning, people, including yourself, had a vision of where the internet was going to go. Are you surprised, though, that at this point the IP protocol seems to beat almost anything it comes up against?Cerf: I’m not surprised at all because we designed it to do that.This was very conscious. Something we did right at the very beginning, when we were writing the specifications, we wanted to make this a future-proof protocol. And so the tactic that we used to achieve that was to say that the protocol did not know how — the packets of the internet protocol layer didn’t know how they were being carried. And they didn’t care whether it was a satellite link or mobile radio link or an optical fiber or something else.We were very, very careful to isolate that protocol layer from any detailed knowledge of how it was being carried. Plainly, the software had to know how to inject it into a radio link, or inject it into an optical fiber, or inject it into a satellite connection. But the basic protocol didn’t know how that worked.And the other thing that we did was to make sure that the network didn’t know what the packets had in them. We didn’t encrypt them to prevent it from knowing — we just didn’t make it have to know anything. It’s just a bag of bits as far as the net was concerned.We were very successful in these two design features, because every time a new kind of communications technology came along, like frame relay or asynchronous transfer mode or passive optical networking or mobile radio‚ all of these different ways of communicating could carry internet packets.We would hear people saying, ‘The internet will be replaced by X25,’ or ‘The internet will be replaced by frame relay,’ or ‘The internet will be replaced by APM,’ or ‘The internet will be replaced by add-and-drop multiplexers.’Of course, the answer is, ‘No, it won’t.’ It just runs on top of everything. And that was by design. I’m actually very proud of the fact that we thought of that and carefully designed that capability into the system.This is the approach Quant have taken with their Blockchain OS, Overledger to solve Blockchain interoperability. Compared to other Interoperability platforms that are trying to achieve interoperability at the transaction layer by connecting two blockchains via another blockchain, these will be ultimately be made redundant once faster methods are released. Overledger is designed to be future proof by isolating the layers so it doesn’t matter whether it’s a permissioned blockchain, permissionless, DAG, Legacy network, POW, POS etc because it abstracts the transaction layer from the messaging layer and runs on top of blockchains. Just as the Internet wasn’t replaced by X25, frame relay, APM etc, Overledger is designed to be future proof as it just runs on top of the Blockchains rather than being a blockchain itself. So, if a new blockchain technology comes out that is capable of 100,000 TPS then it can easily be integrated as Overledger just runs on top of it.
Likewise, with protocols such as HTTPS, SSH etc these will also emerge for blockchains such as ZK-Snarks and other privacy implementations as well as other features made available, all will be compatible with Overledger as its just sitting on top rather than forcing their own implementation for all.
It doesn’t require blockchains to fork their code to make it compatible, it doesn’t add the overhead of adding another blockchain with another consensus mechanism (most likely multiple as it has to go through many hops). All of this adds a lot of latency and restrictions which isn’t needed. The developer can just choose which blockchains they want to connect and use the consensus mechanisms of those blockchains rather than forced to use one.
Overledger can provide truly internet scale to meet whatever the demands may be, whether that be connecting multiple red belly blockchains together with 440,000 tps it doesn’t matter as it doesn’t add its consensus mechanism and uses proven internet scale technology such as that based on Kubernetes, which is where each task is split up into a self-contained container and each task is scaled out by deploying more to meet demand. Kubernetes is what runs Google Search engine where they scale up and down billions of containers every week.
Due to this being more of a summary, I strongly recommend you read this article which goes into detail about the different layers in Overledger.
But how does it provide the security of a blockchain if it doesn’t add its own blockchain?This is often misunderstood by people. Overledger is not a blockchain however it still uses a blockchain for security, immutability, traceability etc, just rather than force people to use their own blockchain, it utilises the source and destination blockchains instead. The key thing to understand is the use of its patented technology TrustTag, which was made freely available to anyone with the Overledger SDK.
Please see this article which explains TrustTag in detail with examples showing how hashing / digital signatures work etc
A quick overview is if i want to send data from one blockchain to another the Overledger SDK using Trusttag will put the data through a hashing algorithm. The Hash is then included in digital signature as part of the transaction which is signed by the user’s private key and then validated through normal consensus and stored as metadata on the source blockchain. The message is then sent to the MAPP off chain. The MAPP periodically scans the blockchains and puts the received message through a hashing algorithm and compares the Hash to the one stored as metadata on the blockchain. This ensures that the message hasn’t been modified in transit, the message is encrypted and only the Hash is stored on chain so completely private, provides immutability as it was signed by the user’s private key which only they have and is stored on the blockchain for high availability and secure so that it can’t be modified, with the ability to refer back to it at any point in time.
Despite Overledger being a very secure platform, with the team having a very strong security background such as Gilbert who was chief security information officer for Vocalink (Bank of England) managing £6 trillion of payments every year and classified as national critical security (highest level you can get), ultimately you don’t need to trust Overledger. Transactions are signed and encrypted at client side, so Overledger has no way of being able to see the contents. It can’t modify any transaction as the digital signature which includes a hash of the transaction would be different so would get rejected. Transaction security isn’t reduced as it is signed at source using however many nodes the source blockchain has rather than a smaller amount of nodes with an interoperability blockchain in the middle.
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.
Treaty ContractsWhat 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 versionThe 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 versionThe 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 TeamThe 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.

Third-party crypto-loan company NEXO accepts BNB as collateral for its loans, which can go as high as $2 million. In Conclusion Binance has rapidly become one of the top fee-based cryptocurrency exchanges in the world, and many of the traders on the platform are fiercely loyal, which should help support the value of BNB tokens for a long time. Crypto trading giant Binance created a corporate plan for profiting from the U.S. market while avoiding regulatory scrutiny, Forbes reported, citing a leaked document. Trade over 40 cryptocurrencies and enjoy the lowest trading fees in America. Binance had an apparent leak of up to 60,000 users’ know-your-customer verification data, though it pointed a finger at a third-party service provider at the time. They also suffered a funds loss worth $40 million during a hack in May 2019. However, they had a separate fund for such cases and they refunded all users with the money from that fund. Binance CEO Changpeng Zhao, a self-proclaimed Bitcoin permabull, has opined that the world’s largest cryptocurrency could be replaced a government-issued crypto asset during a Fortune interview. “If the government pushes another cryptocurrency that is ever more open, more free, has less restrictions than Bitcoin, and is faster and cheaper to use, then that would threaten Bitcoin, but that ...
