Digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. More generally speaking, digital currency is actually a commodity
just like gold, it took more than 200 years to be graally recognized by the world. In the early days, many people questioned gold's ability to store value. If we take digital currency as a substitute, people's questioning attitude towards gold in the past is equivalent to many people's attitude towards digital currency now
extended data
digital currency is a balance between financial security and innovation ability. Financial instry should have clear access threshold. Digital currency involves finance, so it must have clear access threshold. The enterprise qualification of blockchain and digital currency needs to be reviewed and an access system set. One of the core of supervision is that blockchain enterprises must have qualified technical personnel
for example, enterprises of different levels in the construction instry need different levels and numbers of registered structural engineers to ensure the safety of buildings and bridges, which can also be used for reference in the supervision of digital currency. In addition, investors need to refer to the requirements of the "measures for the appropriateness of securities and futures investors" issued by the CSRC, and only those who meet certain conditions can participate in the investment
The people's Bank of China has not issued digital currency for the time being, so there is no legal digital currency in China at present. At present, digital currency has not been recognized in China, let alone legal
at present, all kinds of digital currencies circulating in the market are basically on the edge of the law. China maintains a neutral attitude, but does not like speculation, which is also the basic attitude of the central bank{ RRRRR}
< H2 > development materialsdigital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English and the alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy
digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency
Due to the continuous popularity of bitcoin, people begin to pay close attention to this kind of digital currency. However, people from all walks of life pay more attention to the technical architecture behind bitcoin - blockchain technology, which is considered by many organizations to be the core technology most likely to trigger the fifth round of scientific and technological revolution after steam engine, power, information and Internet technology
bitcoin may fall, while the long-term direction of digital currency is bound to rise, and the rise will be particularly fierce. In 2017, the total market value of global digital currency was only US $647 billion, less than 10% of the global physical gold market value, and less than 0.01% of the total national stock value. AAC is launched at the right time. Miners all know that the earlier they enter, the more tokens they can get and the more profits they can earn. The birth of acute angle cloud will bring huge returns to its partners
2017 can be regarded as the first year of blockchain technology, and 2018 is likely to be the explosive year of blockchain technology. The rapid development of the blockchain technology will probably usher in the explosive growth of acute angle cloud, and the acute angle PC released on ces2018 is likely to become another explosive proct of blockchain

exchange pain point ③ management problem
difficult reconciliation, difficult assignment of permissions, scattered private key
solution: multi-level multi currency wallet, The unified management of a seed private key
accurately corresponds to the current problems of the exchange and provides corresponding solutions, so it solves the problems of the exchange.
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.
