Check virtual currency
in view of the possible risks of virtual currency, many international organizations and central banks have responded publicly to the supervision of virtual currency system. These responses can be roughly divided into four categories: warning and risk warning, supervision and registration permission, legislative norms, and explicit prohibition
(1) warning and risk warning
some central banks and regulators have issued risk warnings against the special currency and virtual currency system. The federal financial regulatory authority of Germany, the Bank of France, the central banks of the Netherlands and Belgium have issued public warnings against the possible money laundering and terrorist financing caused by the use of bitcoin. In the report released at the end of 2013, the European Banking authority (EBA) warned consumers of many risks of virtual currency, such as exchange loss, e-wallet theft, unprotected payment, price fluctuation and so on. Although Spain did not have a similar risk warning, it issued a timely information announcement related to virtual currency
(2) supervision and registration license
generally speaking, international organizations believe that the supervision of virtual currency should find a balance between risk prevention and innovation promotion. Since 2012, Sweden has required transactions related to virtual currency to be registered with financial regulators. Other countries pay attention to qualification supervision, so as to make it indirectly meet the requirements of prudential supervision. In other countries, the regulation mainly focuses on the business model of virtual currency transaction. The financial prudential regulatory authority of France regards the provision of bitcoin circulation and trading services and the act of earning funds in the process as a payment service and requires the authorization of the government. In addition, some countries focus on the intermediary institutions related to virtual currency. The German federal financial regulatory agency and Danish regulators believe that the provision of intermediary services for virtual currency needs to be authorized< (3) legislative norms
at present, some countries have proposed legislation to regulate virtual currency transactions. Canada plans to legislate to allow the government to supervise the transaction of bitcoin, and to include the transaction of more than US $10000 into the scope of suspicious supervision. The United States hopes to adjust the relevant legal structure should be compared with the development of the special currency. In order to make the Bank Secrecy Act (BSA) applicable in the context of network, the financial crime enforcement network (FinCEN) of the U.S. Department of the Treasury issued the explanatory guidance on the behavior and subject definition of private generation, holding, distribution, trading, acceptance and transmission of virtual currency in 2013. The European central bank stressed that it should strengthen international cooperation under the existing legal framework, and regulate virtual currency from the European and global level under the existing legal framework. More countries believe that bitcoin is not a currency in circulation, has no legal status, and does not meet the definition of financial instruments, such as Finland, Sweden, Malaysia and Indonesia
(4) it is forbidden
in some countries, bitcoin related transactions are prohibited. In December 2013, the people's Bank of China banned financial institutions from trading in bitcoin, which was subsequently extended to payment service providers. The central banks of Thailand and Indonesia share the same attitude. The circulation of anonymous internet currency (including bitcoin) is prohibited by the Russian judicial inspection department as a substitute for currency. The Central Bank of Russia has earlier included the provision of bitcoin services in the scope of suspicious transaction monitoring. The U.S. Securities and Exchange Commission (SEC) has banned the issue of unregistered shares in exchange for bitcoin, and unregistered online securities trading activities in virtual currency.
Background: the financial application of blockchain technology brings high investment value
2018 China international big data instry Expo opened in Guiyang City, Guizhou Province on the 26th. At the meeting, it was pointed out that China will vigorously develop the digital economy in the future, deeply implement the action plan for the development of big data and cloud computing, and deeply study blockchain technology and application. Especially in the field of finance, the landing application has become the focus of the scientific and financial circles
1. The value source of blockchain is that it can perfectly solve the pain points of the current financial instry:
in today's asset securitization, insurance, supply chain finance, commodity trading, asset custody and other financial scenarios, e to many participants, high cost of credit evaluation, low settlement efficiency of intermediary institutions and other reasons, Traditional financial service methods are difficult to effectively solve the long-standing core pain points in the instry, such as information asymmetry, complex and rendant processes, and high information verification cost
2. Why can blockchain solve the above pain points:
blockchain technology integrates many basic technologies, such as distributed accounting, tamper proof, built-in contract, etc., and constructs a trust building mechanism with lower cost. The financial application based on blockchain technology can realize the ability of all market participants to obtain all transaction information and asset ownership records in the market without discrimination, and effectively solve the problem of information asymmetry; Smart contract embedding reces the error rate of payment and settlement, simplifies the process and improves efficiency; At the same time, based on transparent information and brand-new trust mechanism, there is no need to spend manpower, material resources and financial resources to confirm information among participants, which will greatly rece the trust cost between institutions, and then rece the price of financial services and transaction costs
3. The application of blockchain technology in the financial field mainly includes the following aspects:
① digital currency
among which bitcoin is the most famous. On the basis of bitcoin, a large number of other types of decentralized digital currencies have been derived. Such as: the heyday of bits
Compared with the traditional payment system, blockchain payment can directly carry out end-to-end payment for both parties without the help of the banking system, which can greatly improve the speed and rece the cost③ digital bills
④ bank credit management: the advantage of blockchain is that it can rely on program algorithm to automatically record credit related information and store it on every computer in the blockchain network, with transparent information, tamper proof and low cost
The major financial institutions and exchanges in Europe and the United States have explored the application research of building the next generation of financial asset trading platform based on blockchain technology4. The development prospect of blockchain. The future development of blockchain technology will have the most vitality with alliance chain as the entry point, and will have a significant effect and far-reaching impact on the transformation of traditional financial instry pain points
in response to the good investment prospects of blockchain, domestic enterprises such as Alibaba, Jingdong and Netcom have entered the market. The application of financial scenarios based on blockchain technology not only brings us security and convenience, but also provides us with broader investment space. The rise and price surge of digital currency represented by bitcoin (bitcoin was about RMB 20 cents when it was first listed in 2009, and its current price is about US $7300!) It's the best proof that people with a keen sense of smell have made a lot of money from it
Abstract: This is an encrypted digital currency based on the bitcoin developed by Nakamoto Tsung, which improves and adds many new functions, such as the double-layer reward system network, also known as the main node network. It also includes anonymous payment to improve the interchangeability (bitage) and real-time payment function docking to realize real-time transaction confirmation without relying on the authority of the center (P2P mall) In 2009, Nakamoto put forward the concept of bitcoin. Since then, bitcoin has spread rapidly in mainstream applications and commercial uses, becoming the first digital currency to attract a large number of users, which is a milestone in the history of digital currency. However, from the perspective of completing the transaction, we can find an important problem, that is, it takes too long for bitcoin block to confirm the transaction. Traditional payment companies have found a solution to enable the buyer and the seller to realize zero confirmation of bitcoin transaction, but this solution usually requires a trusted third party to complete the transaction outside the agreementbitcoin provides pseudonym transaction, realizes the one-to-one transaction relationship between sender and receiver, and can always record the transactions occurred in the whole network. Bitcoin only provides low-level privacy protection, which is well known in academia. Despite this deficiency, many people still believe in the transfer history recorded by blockchain
based on Nakamoto's achievements, bitshengshi is an encrypted digital currency with the purpose of protecting privacy. We have made a series of improvements on the basis of the concept of bitcoin, resulting in a decentralized cryptocurrency with good anonymity. It supports tamper proof real-time transactions, and has a point-to-point sub network that can provide service reward system for bitsheng network
2. Master node network
the whole node is the server running on the P2P network, so that small nodes can use them to accept the dynamic changes from the whole network. These all nodes need significant traffic and other resources that consume a lot of cost. Therefore, it will be observed that the number of these nodes on the bitcoin network presents a steady downward trend over a period of time, so that the block broadcast time needs an additional 40 seconds. In order to solve this problem, many solutions have been put forward, such as the introction of Microsoft Research's new incentive plan and bitnodes incentive plan

seeing the answers from other friends, most of them are foreign websites, or the market is incomplete
the website of Yingwei Caiqing can view up to 2500 + digital currencies
at the same time, the app of Yingwei Caiqing can also be downloaded from major mobile app stores
at the end of 2013, the central bank and other five ministries and commissions jointly issued a bitcoin risk notice, in which bitcoin was clearly defined as a special Internet commodity. People can buy and sell bitcoin freely at their own risk, denying its monetary attribute, and no finance can participate in bitcoin related business. Bitcoin home has the full text<
Zhou Xiaochuan, the governor of the central bank, said that bitcoin is a tradable asset like a stamp, which is not issued by the central bank, and the central bank has no right to ban bitcoin.
