Blockchain list Dongfang Guoxin

1. How to explain the concept of blockchain? The understanding of people in each instry is different, and the relevant explanations are graally emerging because of more and more practical applications. With the popularity of this blockchain technology, the relevant achievements are also growing. If we want to understand this kind of technology, we must have a deep understanding from the reality

in the past six months, the concept of blockchain has graally become hot in China, and the financial circle has been blowing waves of blockchain whirlwind. With its unique technical advantages, blockchain has attracted more and more attention and favor from people in the instry. With the characteristics of decentralization (or multi centralization), high transparency, impossibility of tampering and no single point of failure, blockchain technology is coming into the vision of financial institutions and enterprises. At least it has been applied from theoretical discussion to practical application in many fields, such as digital currency, payment and exchange, registration and settlement, digital assets, traceability and anti-counterfeiting, supply chain, Internet of things, etc

"blockchain" was first released in early 2009 as "bitcoin". Blockchain has become the basic protocol and technical application for the launch, recording and circulation of bitcoin. Although bitcoin has been controversial since it came into being, and it can not even be regarded as "currency" by the government and monetary authorities, the blockchain technology applied by bitcoin has been widely concerned by the government and monetary authorities

why has blockchain become a hot technology and topic

perhaps the most important of these is that bitcoin, which is based on blockchain technology, has opened a new technology and rule system exploration and attempt, which has little connection with traditional society (offline) and is completely applied to the online world (online), such as Internet users' identity verification, wealth confirmation, transaction records, notarization verification, etc, This provides people with an alternative path and unlimited reverie to adapt to the development of the Internet society
from the perspective of its application in bitcoin, blockchain intuitively means a new set of network block (block, also known as community) establishment, bitcoin configuration, netizen identity verification, and bitcoin (value) confirmation and transaction records formed by mining by combining encryption technology with Internet technology, As well as the extended encryption of bitcoin cross block flow (value transfer) (including factors such as block and transaction time identification) registration and verification, the internet protocol rules and ledger system including block chain, whole process encryption and mutual authentication. Because bitcoin is not a substitute for offline fiat money, but a new and decentralized network currency (virtual currency) issued and managed by the illegal monetary authority, which mainly imitates the mode of gold and is completely protected and supported by the Internet basic protocol and strict encryption technology, it has also formed a set of virtual currency which is different from It is also not subject to the new monetary rules and systems of social laws, and can be traded or exchanged with legal tender. Bitcoin has been more than eight years since it was launched, and there has been no record of funds or user information stolen. Its security has been verified, and its efficiency and cost of capital clearing also have obvious advantages. This makes people have more confidence in the blockchain technology applied by bitcoin, and it is also more and more clear that although blockchain is a technology and protocol initiated and applied by bitcoin, blockchain is not the same as bitcoin, and its application will never be limited to bitcoin. The application of blockchain can be decentralized or centralized; It can be public chain mode or private chain mode. Therefore, after bitcoin, blockchain technology is constantly developing and innovating, and constantly exploring new application fields, especially in the financial field

the reason why more and more people attach great importance to blockchain is that with the development and wide application of the Internet, more and more economic exchanges and trading activities have been transferred to the Internet, and the network world (or online society) is rapidly expanding, enriching and active, while online transactions must solve the problems of identity verification, value verification, transaction records, etc The efficiency and security protection of inspection and verification need strict intermediary and agreement (rules or constitution). In this regard, the traditional thinking and practice is to conform to the development track of the transfer from offline trading to online trading, and push the common rules and practices of the real (offline) society to the online (Network) society, but it is increasingly difficult to adapt to the needs of online trading in practice
for example, the natural choice of the party's identity verification is to add the account or transaction password, as well as biometrics such as Facebook, iris, fingerprint, etc., based on the information of the identity documents protected by the laws of various countries, to carry out the identity verification of online transactions. But this method, first of all, makes the citizenship information of the cross-border interconnected network world subject to the real social administrative jurisdiction, At the same time, non digital, multi identity information collection and verification will greatly increase the cost and rece the efficiency
moreover, in real society, all kinds of economic activities involving capital liquidation, except direct cash transactions, require the parties to open accounts in banks and other institutions first, and carry out capital liquidation through the account opening institutions. However, for various reasons, even in a country, it is impossible to require all citizens to open accounts in an account opening institution (including its branches), It is even more impossible to do this between multinational companies, which makes the transactions of the parties who open accounts in different institutions must be completed through the clearing between their account opening institutions. It will seriously affect the efficiency and cost of transaction confirmation and capital clearing if this mode is implemented in the network world

in addition, in real society, the valuation and liquidation of trading activities must involve money, which is legal tender protected by national or regional sovereignty. In the case of cross-border Internet Interconnection and cross-border development of Internet transactions, transaction pricing and capital clearing also involve currency issues. The operation of multiple currencies will greatly increase the cost and risk of clearing. Therefore, the development of network world and network transaction needs the innovation of identity verification, value verification, currency valuation, transaction confirmation and record, account management and verification. Bitcoin and blockchain technology provide very important enlightenment and practice

of course, blockchain is still a new concept and technology, which needs further verification and improvement; The application of bitcoin is also an extreme example: the initial bitcoin can not be directly converted from legal tender, but can only be obtained through "mining" in the network world. Therefore, bitcoin can completely set aside the offline social rules, form a new set of game rules by using blockchain technology, and extend from online to offline. In real society, whether online or offline transactions, the main body is people (including legal persons). The management of their wealth or value should not be completely divided into two worlds, but must be connected and integrated. Therefore, o2o is necessary. This requires the application of blockchain not only to study and solve the problems of the network world, but also to study and solve the connection and integration between the network world and the real society. This will bring more challenges and risks, and also require more people, more strength, more in-depth discussion and innovation. It is also possible that blockchain technology will be replaced by more advanced and perfect technology in the future, but the historical value of blockchain will be indelible

the development of blockchain technology in China

Bubi blockchain is a commercial blockchain. Bubi covers seven areas: exchange, points (multiple points, gege points), insurance (sunshine insurance will launch accident insurance on our blockchain in a month, which can greatly rece channel costs), equity crowdfunding (gold stock chain, etc.), supply chain finance (Qian Xiang, etc.), supply chain (cooperation with the material chain, etc.), jewelry anti-counterfeiting, etc. Some funds cooperating with Bubby have committed 150 million investment funds. Bubby plays the role of "LP" in the fund, helping the fund identify and invest in companies related to blockchain. At present, the average amount of angel investment obtained through Bubi blockchain is about 3 million, with an average valuation of more than 40 million

blockchain can drive the birth of a new business model

the characteristics of blockchain technology enable it to achieve some business models that are difficult to achieve in the centralized mode. For example, in the Internet of things instry, some organizations have proposed to use blockchain technology to manage the identity, payment and maintenance tasks of tens of billions of Internet of things devices. Using blockchain technology, IOT equipment manufacturers can greatly extend the life cycle of procts and rece the cost of IOT maintenance

blockchain technology has a flexible architecture

according to different application scenarios and user needs, blockchain technology can be divided into public chain, private chain and alliance chain, which can be selected according to the actual use of institutions<

blockchain technology is a useful tool to realize sharing finance

the essence of sharing finance is to realize the optimal allocation of financial resources by recing the asymmetry of financial information, and to ensure the implementation of the rights and interests of both parties in the transaction and facilitate the transaction through strict third-party authentication and supervision mechanism. Through the use of blockchain technology, financial information and financial value can be more strictly protected, and more efficient and lower cost flow can be realized, so as to realize the sharing of value and information

"from the perspective of historical development trend, money has always evolved with the development of technological progress and economic activities. From the early physical money, commodity money to the later credit money, it is a natural choice to adapt to the development of human commercial society. As the currency of the previous generation, paper money has low technology content. From the perspective of safety and cost, it is the general trend to be replaced by new technology and new procts. It will take at least 10 years for China to implement digital currency, so digital currency and cash will be in parallel and graally replaced for quite a long time. "“ For digital currency, blockchain technology is an optional technology, which is characterized by distributed bookkeeping, non account based and non tampering. If digital currency focuses on the protection of personal privacy, blockchain technology can be selected. The people's Bank of China has deployed an important force to study and discuss blockchain application technology. However, so far, blockchain still occupies too many resources, whether it is computing resources or storage resources, which can not cope with the current transaction scale. Whether it can be solved in the future depends on the situation. "

the development of Internet is in the ascendant and irreversible. The development of the network world and its connection and integration with the real society are also the general trend, and the corresponding rules and technology are of great significance. China has been in the forefront of the world in Internet application, and should actively explore and contribute to new rule making and technology application, and strive to lead the new development of the Internet world

what is the concept of blockchain? People will realize that blockchain technology plays a more and more important role in reality, and is supported by many organizations, so that the popularization of blockchain in reality has entered a new application stage.

1. Litcoin (LTC) is an improved version of digital currency inspired by bitcoin (BTC). It was designed and implemented by a programmer who worked in Google. It was released on November 9, 2011. Lightcoin and bitcoin have the same implementation principle in technology, but the creation and transfer of lightcoin is based on an open source encryption protocol, which is not managed by any central organization

2. Sunshine coin (SSC for short) is sponsored by Liu Chunyang, vice president of Jinhua express delivery Association of Zhejiang Province, instrial entrepreneur and philanthropist of express delivery instry. As a legal person, Zhejiang Dongyang Yueyin Technology Co., Ltd. is registered with the formal instry and Commerce Bureau, with a registered capital of 10 million yuan. With this as the backing and support, the sunshine elite team affiliated to the company launched the first virtual coin sunshine coin

The English name of Vicat is onecoin, which is a kind of Internet virtual currency term created by the government and is suspected of pyramid selling fraud

in 2017, CCTV announced the list of 350 fund pyramid schemes, with Vicat in the list

in May 2018, Zhuzhou County Procuratorate of Hunan Province prosecuted the last four suspects involved in the third batch of the "3.15" Vicat money online pyramid scheme case supervised by the Ministry of public security to the court

4. Amazon coin

Amazon announced in early February 2013 that it is expected to launch Amazon coins in the United States in May 2013. Amazon coins is a new virtual currency that allows U.S. users to buy apps, games and props in the kindle fire. Amazon will provide tens of millions of US dollars of Amazon coins at that time to let users try and consume the apps, games and props in the app on the kindle fire for free

5. Eth is a kind of digital token of Ethereum, which is regarded as "bitcoin version 2.0". It adopts the blockchain technology "Ethereum", which is different from bitcoin. It is an open-source public blockchain platform with intelligent contract results, and a resonance network composed of thousands of computers around the world. Developers need to pay eth to support the application. Like other digital currencies, ether currency can be bought and sold on the trading platform

3. Institutions are beginning to experiment with this new technology
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

4. No
although the currency circle is in a bear market, blockchain is not useless without cryptocurrency
the blockchain instry has developed rapidly in recent years, and more and more blockchain technologies appear in front of people. More and more blockchain applications are landing, blockchain e-invoice, blockchain traceability, blockchain finance and so on. Talents in the blockchain instry are also very scarce. Many colleges and universities in China have set up blockchain courses to provide talents for the blockchain instry
the development of a new technology will inevitably encounter setbacks, and the blockchain instry will grow stronger in the future.

5.

financial field

blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields. The application of blockchain technology in the financial instry can save the third-party intermediary link and realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment

in the field of Internet of things and logistics, blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management. This field is considered as a promising application direction of blockchain

in the field of public service

blockchain is closely related to people's proction and life in the fields of public management, energy, transportation, etc., but the centralization of these fields also brings some problems, which can be transformed by blockchain. The decentralized and fully distributed DNS service provided by the blockchain can realize domain name query and resolution through the point-to-point data transmission service between nodes in the network. It can be used to ensure that the operating system and firmware of an important infrastructure have not been tampered with. It can monitor the status and integrity of the software and detect bad tampering, And ensure that the data transmitted by the system using the Internet of things technology has not been tampered with

in the field of digital right

through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership. After the works are confirmed on the blockchain, the subsequent transactions will be recorded in real time to realize the full life cycle management of digital rights, and can also be used as a technical guarantee in judicial evidence collection

in the field of insurance

in terms of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs. Through the application of smart contract, there is no need for the applicant to apply or the insurance company to approve. As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized

public welfare

the data stored on the blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision
