Where is the virtual currency asset management company

4. blockchain applications include mathematical currency, payment and clearing, digital bills, proof of rights and interests, bank credit
the specific explanation of each application is as follows:
1. Digital currency
at present, the most extensive and successful application of blockchain technology is digital currency represented by bitcoin. In recent years, digital currency has developed rapidly. Due to the characteristics of decentralized credit and frequent transactions, it has high transaction value and can maintain a relatively stable price by developing hedging financial derivatives as quasi super sovereign currency. Digital currency establishes the digital currency transaction credit under the endorsement of sovereign currency. The larger the transaction volume is, the more frequent the transaction is, and the stronger the credit foundation of digital currency transaction is. Once the global blockchain credit system is realized, digital currency will become a gold like universal payment credit
2. Payment and clearing
at present, the clearing and payment of commercial trade transactions all rely on banks, and this traditional way of trading through intermediaries has to go through the opening bank, the counterpart bank, the central bank and overseas banks. In this process, each institution has its own accounting system, and they need to establish agency relationship and credit line; Each transaction needs to be recorded in the bank, and also needs to be cleared and reconciled with the counterparties, resulting in slow transaction speed and high cost. Compared with the traditional payment system, blockchain payment is carried out directly by both sides of the transaction, and does not involve intermediate institutions. Even if part of the network is paralyzed, the operation of the whole system will not be affected. If we build a set of general distributed inter-bank financial transaction protocol based on blockchain technology to provide users with cross-border, any currency real-time payment and clearing services, cross-border payment will become convenient and low-cost
taking cross-border exchange as an example, if I open an account in a small bank in my own country and remit money to another small bank abroad, the transfer process under the traditional swift system needs the following steps: first, I submit an application to my own small bank; Second, small banks submit applications to large banks in the same country with exchange terms; Third, large banks wire overseas cooperative banks; Fourth, cooperative banks remit money to small overseas banks. At present, depending on the host country, the process can take from 10 minutes to two days. If the settlement technology based on blockchain is used, when the RMB is remitted, the bill is registered at the market maker, and a trading bank in the world receives the bill, the two sides shake hands to complete the exchange, and the average speed of payment confirmation is within a few seconds
3. Digital bill
Digital bill is a new form of bill presentation developed by combining blockchain technology with Bill attributes, regulations and market, which is completely different from the existing technical architecture of electronic bill system. The core advantages of digital bill are as follows: first, to realize the disintermediation of bill value transmission. In the traditional bill transaction, the bill intermediary often uses the information gap to match. After the point-to-point transaction with the help of blockchain, the bill intermediary will lose its intermediary function and re position its identity. The second is to effectively prevent the risk of bill market. Due to the characteristics of tamperable time stamp and network wide publicity, once a transaction is made, there will be no default phenomenon in blockchain, thus avoiding the problems of "one vote for more sales" of paper tickets and asynchronous endorsement of e-tickets. Third, the construction of the system and data storage do not need the central server, which saves the development cost of the central application and access system, reces the maintenance and optimization cost of the system under the traditional mode, and reces the risk brought by the system centralization. Fourth, standardize the market order and rece the cost of supervision. The non tamperable time stamp formed by the front and back connection of blockchain data greatly reces the access cost of supervision. The completely transparent data management system provides a trusted traceability way, and can establish a common constraint code for the supervision rules in the chain by programming, so as to realize the full coverage and hard control of supervision policies
4. Proof of equity
each node participating in the maintenance of the blockchain can obtain a complete data record, which can confirm the ownership of the equity by using the characteristics of reliable and collective maintenance of the blockchain. For the demand of storing permanent records, blockchain is an ideal solution, which is suitable for land ownership, equity trading and other scenarios. The equity certificate is the most widely used field at present. The equity owner can prove the ownership of the equity by virtue of the private key. When the equity is transferred to the next family through the blockchain system, the property right is clear and the record is clear. The whole process does not require the participation of a third party
in the keynote speech of the 2015 European news award for trade technology and finance excellence in London, NASDAQ CEO Bob Greifeld announced that the exchange intends to use blockchain technology to manage proxy voting system. Proxy voting is originally an important and time-consuming operation used by a listed exchange. The application of blockchain technology enables shareholders to participate in voting without attending the company's annual general meeting. People can vote with their own mobile phones and keep voting records forever. Blockchain technology is regarded as an advanced technology in the field of equity trading, which can ensure transparent trading in a shorter time
5. Bank credit investigation
at present, the most basic consideration in the development of commercial bank credit business, whether for enterprises or indivials, is the financial credit possessed by the borrowers themselves. Each bank uploads the repayment status of each borrower to the credit reference center of the central bank, and then downloads the reference from the credit reference center of the central bank on the premise of customer authorization. There are some problems such as incomplete information, inaccurate data, low efficiency and high cost. In this field, the advantage of blockchain lies in relying on program algorithm to automatically record massive information and store it on every computer in the blockchain network, with transparent information, high tampering difficulty and low use cost. All commercial banks store and share customers' credit status in their own institutions in the form of encryption. When customers apply for loans, they do not have to go to the central bank to apply for credit investigation, that is, decentralization. Lending institutions can complete all credit investigation work by retrieving the corresponding information data of the blockchain
in a word, blockchain has become one of the hot spots of financial innovation, but as a new technology, blockchain also has considerable risks. At present, the settlement system based on blockchain technology is very sensitive to regulatory risks. If participants worry about the uncertainty of regulatory policies, the payment system may collapse e to instability. In addition, because the operation right is controlled by the developer, the obvious technical disadvantage is that if the operator itself controls more than 51% of the computing power of the whole network, it can achieve double payment, leading to the collapse of trust. This is also an important issue to be solved in the application of blockchain technology.

The bitcoin white paper was first published at the end of 2008, when the creators sent it to multiple recipients on an encrypted mailing list. Strangely, its creator pretended to be Satoshi Nakamoto, hiding behind the pseudonym

Another reason for Nakamoto's anonymity can be explained as that the creators of alternative currencies easily put themselves at risk

In 1998, Hawaiian resident Bernard von nohaus created a private currency called free dollar. It has been popular for some time, but its coinage was suddenly raided by the FBI and secret service in 2007. After a criminal lawsuit in 2009, the money was confiscated and Bernard von norhaus was convicted of "making private coins that compete with the official currency of the United States."

In addition, in 2007, a digital currency called e-gold was accused of being illegal because it did not collect enough customer information. Its owner was sentenced to house arrest and the company was shut down. The arrest of entrepreneurs in alternative currencies by government agencies may have been a factor in China's decision to remain anonymous

everyone can use bitcoin. This means it can be used to pay for legal and illegal services, as well as legal bids however, it has always been a popular payment method in the black net market. Ross Ulbricht, the notorious dark Internet market maker and operator, was jailed for facilitating the trading of drugs and other contraband

Ross Ulbricht appealed to the US Supreme Court in December 2017, but is still in prison. If Nakamoto reveals his true identity, it can be inferred that he may face a similar fate

who would he be

in 2016, Craig Wright, an Australian programmer, claimed to be Chinese. He provided some evidence, but later found that it was not conclusive because it could be obtained publicly from books. He was also accused of falsifying announcements and blog posts to show his real Chinese version. For example, vitalik buterin, founder of Ethereum, recently called Craig white a liar

The other is Hal Finney. He is a famous cryptopunk and Cryptologist. He was also the first person to receive bitcoin from Nakamoto in 2009. He was also the first to download a bitcoin client. Before his death in 2014, however, Hal fini refuted the claim that he was Chinese

Some people think that Nick Saab, a famous Cryptologist, may be Nakamoto. Before the launch of bitcoin, he designed the architecture of distributed digital currency, which he called bitcoin. Although the architecture has never been moved, it is similar to the design of bitcoin. This led to widespread speculation. But he repeatedly denied it

although the real identity of Nakamoto may never be disclosed, it is important that the operation of the technology will not be affected
