1. Jinrong China Financial Instry Co., Ltd.

this is a digital currency trading platform in Hong Kong. At the beginning of trading, it developed on the principle of safeguarding the rights and interests of customers. Similarly, in order to expand trading customers, the company launched the privilege of opening accounts free of charge, and gave customers some concessions in some festivals, This is an important reason why the enterprise takes the first place in the domestic formal blockchain platform

2. Bitfinex

is a digital currency trading platform in Hong Kong, China. It is one of the largest cryptocurrency exchanges in the world. It occupies an important position in the world's cryptocurrency trading and circulation. It also provides the world's most liquid registration policy and plays an important role in the world's trading operations, At present, it occupies the second place in the domestic regular blockchain platform

3. Fire coin network

this is an earlier digital currency trading platform in China, mainly trading bitcoin. As the third instry of domestic regular blockchain platform, it is the trading platform with the largest bitcoin trading volume in China. Many new digital asset trading platforms have been developed under the company, For the future development of the foundation

This is a digital currency trading platform jointly established by some digital currency enthusiasts, and its founder is Zhao CHANGPENG. In fact, this trading platform didn't attract much attention at the beginning. With the continuous operation of the company and the founder's understanding of digital currency, this enterprise has become the top four domestic regular blockchain platforms, which shows the power of this platform

This is one of the most popular digital asset trading platforms in the world. There are many kinds of digital currencies for trading, and their main functions are cash out and derivative trading. They are well-known in the world's exchanges

3. Blockchain mainly solves the trust and security problems of transactions, so it proposes four technological innovations to solve this problem:
(1) distributed ledger, that is, transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, so they can participate in monitoring the legitimacy of transactions, At the same time, they can testify together
different from traditional distributed storage, the uniqueness of distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to block chain structure, while traditional distributed storage generally stores data in multiple copies according to certain rules. Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes[ 8]
no single node can record the account data separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. In theory, unless all the nodes are destroyed, the accounts will not be lost, so as to ensure the security of the account data
(2) asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
(3) consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security
the consensus mechanism of blockchain has the characteristics of "the minority is subordinate to the majority" and "everyone is equal", in which "the minority is subordinate to the majority" does not completely refer to the number of nodes, but also can be the computing power, the number of shares or other characteristics that can be compared by computers“ "Everyone is equal" means that when the nodes meet the conditions, all nodes have the right to put forward the consensus results first, and then directly recognized by other nodes, and finally may become the final consensus results. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes in the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) smart contract, which is based on these trusted and tamperable data, can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts

Blockchain finance is actually the application of blockchain technology in the financial field

blockchain is an underlying technology based on bitcoin, and its essence is actually a decentralized trust mechanism. Through sharing in distributed nodes to maintain a sustainable database, the security and accuracy of information can be achieved. The application of this technology can solve the trust and security problems in the transaction, and the blockchain technology has become an optional direction for the future upgrading of the financial instry. Through the blockchain, both parties of the transaction can carry out economic activities without the help of the third-party credit intermediary, so as to rece the cost of the global transfer of assets

extended data:

since 2016, the major financial giants have also heard the news and launched blockchain innovation projects one after another to explore the possibility of applying blockchain technology in various financial scenarios. In particular, Puyin group took the lead in creating a "blockchain +" standard digital currency. Standard digital currency refers to the process of assets identification, evaluation, right confirmation and insurance completed by a third party organization. After careful digital algorithm, it is written into the blockchain to form the standard corresponding relationship between assets and digital currency, which is called standard digital currency

in order to realize the great leap forward development of blockchain finance, promote the new development of China's economy, accelerate the global asset circulation, and realize the dream of rejuvenation that has been struggling for generations, Puyin group will hold the Guiyang strategic development ceremony of Puyin blockchain finance in Guizhou on December 9, 2016, at which the discussion on the realization of digital circulation of assets, block chain financial transaction mode, and block chain financial transaction mode will be held It also discusses the application of blockchain service and social public instry

5. The development of blockchain financial trading platform includes:
cross border payment, supply chain finance, insurance, digital bill, asset securitization, bank credit reference and other fields
① cross border payment. Due to the characteristics of disintermediation of blockchain, openness, transparency and non tampering of transactions, no third-party payment institutions join in, which shortens the payment cycle, reces costs and increases the transparency of transactions< (2) digital bill. Blockchain has the characteristics of disintermediation, system stability, consensus mechanism and tamper proof, which can rece the operational risk, market risk and moral risk in the traditional centralized system< (3) credit management. In the field of credit investigation, blockchain has the characteristics of decentralization, distrust, timestamp, asymmetric encryption and smart contract, which ensures that limited and controllable credit data sharing and verification can be realized on the basis of effective protection of data privacy< (4) asset securitization. The characteristics of blockchain disintermediation, consensus mechanism and non tampering can increase the efficiency of data flow, rece costs, monitor the real situation of assets in real time, and ensure the trust of all parties in the transaction chain on the underlying assets< (5) supply chain finance. Due to the characteristics of disintermediation, consensus mechanism and non tampering of blockchain, it does not need a third-party credit enhancement agency to verify the authenticity of various relevant vouchers on the supply chain, so as to rece the financing cost and financing cycle< (6) insurance business. With the development of blockchain technology, personal health status, accident records and other information may be uploaded to the blockchain in the future, so that insurance companies can obtain risk information more timely and accurately when customers take out insurance, so as to rece underwriting costs and improve efficiency. The sharing transparency of blockchain reces the information asymmetry and the risk of adverse selection; The characteristics of its history can be traced, which is concive to recing the moral hazard, thus recing the difficulty and cost of insurance management.

6. Don't touch the coin circle. The dividend period has passed, and the future eliminated proction capacity released by the government this year includes Internet coin circle mining. In the past, the state only acquiesced in this area of development, because it wanted to try new and unknown areas, but now it seems that it has clearly rectified this area!

7. Many, generally choose foreign, domestic can't trade.

8. Yingchi Hall of fame is the top non-public graphics card. Although the time of silent frequency is similar to 1060, the ability of overclocking is much stronger than 1060. The official power consumption is 165W, while 1060 is 120W. After overclocking, the power consumption will be higher. Pay attention to whether the power supply is enough. The price of 900 yuan can be bought, but please note that if you play a stand-alone game, it may explode in some games. As for mining, so to speak, there is no ore card in the 9 series, and the N card mining was started on a large scale in the 10 series. It may have been before, but it's too few. Before the 10 series, they used to dig with a-card.

9. Regulatory Technology (regtech), like financial technology, is a new hybrid word in recent two years. Regulatory technology is composed of regulation and technology. IIF defines it as a new generation of technology application that can effectively solve regulatory and compliance requirements. It is believed that with the maturity and popularization of blockchain technology, regulatory technology will play an increasingly important role in the field of financial regulation
faced with the changing regulatory environment, financial institutions have become a heavy burden to invest in compliance costs and increase the amount of fines. From 2012 to 2014, JPMorgan spent $600 million to recruit 13000 employees to deal with financial regulation. At the same time, for regulators, increasingly stringent and escalating financial compliance requirements make regulatory data increasingly diverse and huge
improving real-time data processing, data analysis and automation has become an important demand in the financial field. Regulatory technologies such as blockchain, artificial intelligence, cloud computing, machine learning and big data are used to automatically collect fixed and non fixed data, efficiently analyze customer identity management, compliance, risk prediction, real-time transaction monitoring, data and internal management, and put forward risk prediction results report. That is to say, regulatory technology makes financial regulatory business it, which can improve the level of regulatory operation and effectively prevent financial risks.
