Oasis blockchain
DTCC is a clearing house in the United States, which processes billions of dollars of transactions every year. The global credit card processing network visa is only one of the most well-known pilot projects carried out by non banks. That is to say, some financial sectors are certainly more active than others
major stock and commodity exchanges can be said to be the most active institutions participating in blockchain experiments. For example, NASDAQ, a major U.S. stock exchange provider, even released its own blockchain trading model last fall. This program, called LINQ, can trade and track the shares of private companies. NASDAQ has positioned it as an early experiment of blockchain technology to expand the scope of major stock trading and even the scope of new asset classes< br />Blockchain_ Stock exchanges
although the subtle areas are more different, the 10 major stock and commodity exchanges in the world have shown interest in blockchain technology. In this article, we will give you a detailed introction:
1. Australian Stock Exchange (ASX)
when it comes to the application of blockchain technology, ASX is definitely one of the most ambitious companies. In January, ASX invested more than US $10 million in digital asset holdings, a start-up company in the instry, as part of its R & D activities
at the same time of investment, ASX also revealed that it will not only conct technical tests, but also establish a new post transaction settlement system, which will be developed by digital asset through the use of distributed general ledger structure
however, since January this year, the update progress of the project on the Australian Stock Exchange may have been overshadowed by controversy. In March this year, the Australian news media began to speculate that although the Australian Stock Exchange has reiterated its support for the experiment, the blockchain project may also be in doubt with the premature resignation of Elmer Funke Kupper, the chief executive of the Australian Stock Exchange< CME Group is one of the founders of "post trade distributed ledger working group". At present, CME Group has carried out very positive actions in the instry through its investment department CME ventures
CME Group is unique among its peers. It has been pursuing a diversified investment strategy across instries. It has successively invested in ripple, a distributed accounting start-up company, digital currency group and digital asset holdings. Beyond that, however, CME Group has yet to speak publicly about its actions in technology and the wider instry< br />3.Deutsche B� 0� 2rse
Deutsche B & 65533, the operator of Frankfurt Stock Exchange in Germany; 0� 2rse, another participant on the list, also participated in the $60 million financing of digital asset holdings in January< However, unlike its joint investor ASX, Deutsche B & 65533; 0� 2rse expresses less support for technology
in an interview in February this year, Deutsche B & 65533; 0� 2rse said it is concting a proof of concept for the technology, although it has not released any survey or test results
4. Du multi commodity trading center
in the Middle East, blockchain related activities are relatively rare, and this situation has continued until the recent opening of the global blockchain Council. With 32 members, the global blockchain Council is a group of start-ups, financial companies and technology giants to monitor the application of technology and its impact
based on these members, Du multi Commodities Center is a special economic zone and commodity circulation center responsible for supervising the trading of precious metals and other tangible commodities
DMCC announced in February that it is engaged in a technology experiment with bitoasis, a bitcoin start-up company, to explore how blockchain technology can improve its personnel's entry process< JPX is one of the most active stock market operators in Asia. In February, JPX announced its interest in the instry and has formed an alliance with IBM to become a user of blockchain-as-a-service (baas)
at that time, relevant reports said that the Japanese exchange group was concting a proof of concept study on the role of blockchain technology in creating a new low liquidity asset trading system, and the final results would be published in a report later this year
earlier this month, the Japanese stock exchange group also announced that it is working with the Nomura Research Institute (NRI) to test how technology can be applied to the stock market< Korea exchange is the only stock exchange in South Korea and one of the new entrants to this list. It announced in February that it will strive to launch a counter trading platform through blockchain technology
in a statement to the local news media, Korea Exchange said it hoped the technology would help rece costs. Details of the trial and the company's participation in the group were not released
7. London Stock Exchange (LSE)
LSE is one of the founders of "post trade distributed ledger working group". When it comes to experiments on blockchain technology, LSE is one of the most dynamic and low-key institutions
the London Stock Exchange is one of the largest groups to follow the steps of R3, a start-up company, and it is the first to say that large financial companies will seek to use cooperation mode to conct blockchain testing, which is beyond the framework of R3
since then, some large financial companies have begun to participate in private proof of concept and operation in certain areas of capital markets involving all parties
in addition, like Kouvola innovation and Japan exchange group, London Stock Exchange is one of the initial customers of IBM's blockchain-as-a-service (baas)
8. NASDAQ
when it comes to testing blockchain technology, NASDAQ is probably the most active organization. Nasdaq, the US stock market operator, launched LINQ, a private equity trading platform for the first time in 2015, and thus became the first financial institution to conct a proof of concept of blockchain. At present, the platform is still in the testing stage
in addition, NASDAQ has reached a cooperation with chain, a blockchain solution provider, and allowed its internal experts to talk openly about blockchain technology
in 2016, NASDAQ continued this momentum. More recently, it has revealed that it is working with Estonia's NASDAQ OMX Tallinn stock exchange to conct a trial to use blockchain technology to rece obstacles to shareholder voting
9. New York Stock Exchange (NYSE)
NYSE is one of the first companies interested in the instry. In 2015, NYSE issued two important statements, both of which are related to bitcoin
in January 2015, NYSE invested in coinbase, a bitcoin service company, as part of its round C financing. At that time, Jeffrey sprecher, chairman of NYSE, said the investment showed confidence in the fact that the millennials would widely use digital currency. He described the millennials as having a more progressive view of value exchange
in May, NYSE will continue to launch bitcoin price index, which will become a competitor of coindesk's bitcoin price index (BPI), which is based on the trading data of coinbase trading platform
10. TMX group
TMX group, the operator of Toronto Stock Exchange, has not clearly expressed its opinions on blockchain technology
however, with Anthony di Iorio (one of the co founders of Ethereum) employed as the organization's first chief digital technology officer, TMX also publicly expressed its interest in blockchain technology for the first time in March this year. Next generation network has become one of the most important blockchain applications in the eyes of the public after the proct release in March
nevertheless, TMX group has indicated that it is in the early stage of generating blockchain strategy, and it may conct technical testing soon
at present, the vast majority of digital currency transactions are concted in exchanges. Among the numerous exchanges, bitfinex, binance, okex and so on are well-known
However, bitcoin and other digital currencies, as decentralized assets, have to be traded in a centralized exchange, which seems to have hidden contradictions and dangers1. Problems and challenges of stock exchanges=“ https://iknow-pic.cdn.bcebos.com/fd039245d688d43fdf16c83b761ed21b0ff43bbf ">
in February 2014, Mt. GOx, the world's largest bitcoin exchange at that time, was stolen 850000 bitcoins, and the price of bitcoin suffered a" cliff "crash on that day. Later, it was revealed that Mt. GOx was in fact a thief, and only 7000 bitcoins were actually stolen
in August 2016, bitfinex, the largest U.S. dollar bitcoin trading platform, suffered a security vulnerability, resulting in the theft of 120000 bitcoins, which was worth $65 million at that time. If converted into the price in December 2017, it would be worth nearly $2 billion
on December 19, 2017, South Korea's youbit exchange was attacked by hackers and lost 4000 bitcoins, and the exchange declared bankruptcy
on December 21, 2017, the Ukrainian liqui exchange was stolen 60000 bitcoins, and the unit price of bitcoin plummeted by US $2000
in 2018, such a drama will only continue
in addition to the threat of hackers, traditional exchanges also have some inherent shortcomings, such as lack of supervision and inefficiency. The security of the exchange for investors can only rely on its own credit, and the cost of running is very low. The stock exchange is regulated at the national level, but there is no such sword of Damocles on the top of the digital currency exchange. Moreover, in an exchange, the same order can only be submitted to one exchange. After the user places an order, the funds used for the transaction will be frozen and can only wait for the completion or cancellation of the transaction. These are undoubtedly inefficient
All in all, the problems of exchanges are the problems of centralization2. Decentralization of exchanges=“ https://iknow-pic.cdn.bcebos.com/86d6277f9e2f070889a173c9e224b899a801f257 ">
(1) the progress of the exchange itself
the upgrade of security means is various. At present, the best use is cold wallet, that is, to keep the digital currency in the offline U disk. At the end of 2017, when the YouTube exchange was attacked, 75% of its assets were withdrawn into the cold purse in time to avoid greater losses. However, it seems to be a helpless way to protect the online assets by offline means. Of course, there should be many other methods, which will not be repeated here
(2) the representative of cross ledger transaction is ripple network, and the operating company is ripple labs, which is a semi centralized system. Ripple is a decentralized clearing agreement. In order to solve the high cost and delay of inter-bank clearing, its base currency is XRP. Ripple network can connect all kinds of assets, such as US dollar, RMB, Japanese yen, bitcoin, etc. to its own network. In this system, U.S. dollars or bitcoin can be converted into reborn currency, and then reborn currency can circulate freely in the network, just as a highway is built between various assets. Due to the support of major banking institutions, the reborn currency achieved nearly 300 times growth in 2017
(3) decentralized exchange
some teams try to use blockchain technology to build a decentralized exchange. This kind of decentralized exchange, to some extent, is an extension of cross ledger trading
bitshares is the most representative of early rising projects. It builds a blockchain development platform with servers scattered all over the world. Even if some of them are attacked, the system will not collapse. Anyone can transfer money and borrow money freely on this platform, and can also quickly build a centralized exchange based on this platform. In order to ensure stable value, bitstocks also require three times of digital assets as collateral. At present, bitstocks are running fairly well
later, with the development of Ethereum and smart contract, the x x protocol came into being. This is an open protocol running in the Ethereum blockchain and a decentralized exchange in the Ethereum ecosystem. The agreement has attracted many investors. At present, it has completed financing and started to build open source software tools and infrastructure. Of course, there are many competitors. Ether Delta, IDEX and oasis DEX are trying to provide similar functions. Moreover, it is a smart contract system based on Ethereum, which only supports erc20 token. If other smart contract public chains start to rise, the demand will be reced
in addition, there are some teams that are entering, such as the domestic road seal agreement, looping (LRC) in English. They adopted a design similar to the X protocol, and also introced a fast payment function similar to the lightning network. It is characterized by trying to match multiple exchanges, the user's order can be broadcast to multiple exchanges, and completed by different exchanges. Moreover, the user can still use the account funds after placing an order, and the user's behavior of transferring part or all of the funds is equivalent to partial or total cancellation. To some extent, it improves the breadth and timeliness of the transaction. However, this system seems to have damaged the "power" of the existing exchanges. Whether we can persuade everyone to play together will be a difficult problem
At present, there is still a long way to go for the construction of decentralized exchange. In 3-5 years, traditional exchange will still be the main battlefield of digital currency However, in the future, it is worth looking forward to let the decentralized digital currency get rid of the shackles of centralizationteams with pure academic background often have a very romantic vision for the future blueprint. The development of blockchain is still in its early stage. It's like building a home in a desert. Oasis is an oasis. On this new oasis, there are amber highways and blooming roses everywhere. It's very romantic. Of course, this is my personal interpretation
the official announcement: the circulation of rose tokens at the start of the main network is about 1.5 billion, and the total upper limit of tokens is 10 billion. Oasis protocol says the word "Rose" has historically been seen as a symbol of privacy. In China, the interpretation of rose is not just romantic. It also means loud and exciting. The code name of Chinese women's football in its heyday is sonorous rose. At that time, the women's football team was a world-class team, and the best place was second in the world
it is officially announced that rose token will be used for all the functions of transaction, pledge and entrustment on Oasis network. Rose's token allocation model is as follows: 1; 2. Early supporters 2.3 billion tokens; 3. Community and ecosystem 2.25 billion tokens; 4. The Foundation donated 1 billion tokens; 5. Strategic partners and reserves of 500 million tokens; 6. Core contributor 2 billion tokens
jlab note: Oasis labs was founded by Professor dawn song Xiaodong, a professor in the Department of computer science at the University of California, Berkeley. It aims to solve the current pain points of blockchain in terms of performance, security and privacy. In July 2018, oasis labs obtained US $45 million in financing, and a16z crypto, Gaorong capital, coin an incubator, polychain and jlab participated in the investment, Coinbase co-founder Fred ehrsam is also involved in the investment in his personal capacity. In mid June, oasis labs officially launched the main network candidate version "oasis amber network". Amber network includes all the core functions when the main network is started, such as pledge and entrustment, fully decentralized consensus layer, integrated ledger wallet (to be launched) and verifier's commission rate tool.
in July, the third generation of artificial heart helped two patients with heart failure regain their lives, marking that the performance of artificial heart devices in China has reached the international level of the same kind. In September, the first batch of artificial heart procts were approved in Chongqing< On July 11, the first self built polar scientific icebreaker, Xuelong 2, was successfully delivered. The first voyage to Antarctica was on October 15. The first land ice breaking operation was carried out on November 20< On September 25th, Beijing Daxing International Airport was officially put into operation, known as the first of the "seven wonders of the new world"< On November 3, gaofen-7 satellite was launched, which can take 3D images as fast as "Avatar". On December 10, the first batch of more than 20 sub meter stereoscopic images were released< On November 28, the National Astronomical Observatory announced that Chinese astronomers have discovered the largest stellar black hole so far.
