What is the code of virtual currency

1. In recent years, blockchain digital assets represented by bitcoin have become popular all over the world. Financial institutions, technology companies, investment companies and other participants at home and abroad have invested a lot of human, material and technical resources in the research, development, design, testing and promotion of blockchain digital assets. In order to realize the main characteristics of "four can and three can't" of blockchain digital assets, we can build the core technology system of digital assets by relying on 11 technologies of security technology, transaction technology and trusted guarantee technology. First of all, security technology is used to ensure the fluidity, storability, controllable anonymity, unforgeability, non repeatable transaction and non repudiation of blockchain digital assets. digital currency security technology mainly includes basic security technology, data security technology and transaction security technology. Basic security technology includes encryption and decryption technology and security chip technology. Encryption and decryption technology is mainly used in currency generation, secret transmission, identity verification and other aspects of digital assets. The establishment of a perfect encryption and decryption algorithm system is the core and foundation of the digital assets system, which needs to be customized and designed by the national password management organization. Security chip technology is mainly divided into terminal security mole technology and smart card chip technology. Digital assets can be traded in the form of mobile terminal based on terminal security mole. As the carrier of secure storage and encryption and decryption operation, terminal security mole can provide effective basic security protection for digital assets. Digital asset system trading platform blockchain technology research and development of data security technology, including data security transmission technology and secure storage technology. Data security transmission technology transmits digital asset information through ciphertext + MAC / ciphertext + hash to ensure the confidentiality, security and non tamperability of data information; Data security storage technology stores digital currency information by means of encryption storage, access control, security monitoring, etc., to ensure the integrity, confidentiality and controllability of data information
transaction security technology includes anonymous technology, identity authentication technology, anti plicate transaction technology and anti-counterfeiting technology. Anonymity technology realizes controllable anonymity of digital assets through blind signature (including blind parameter signature, weak blind signature, strong blind signature, etc.) and zero knowledge proof; The identity authentication technology verifies the user's identity through the authentication center to ensure the validity of the digital asset trader's identity; The anti plicate transaction technology ensures that digital assets are not reused by means of digital signature, serial number and time stamp; Anti counterfeiting technology ensures the authenticity of digital assets and transactions by means of encryption and decryption, digital signature and identity authentication. Secondly, the online transaction and offline transaction of digital assets are realized by transaction technology. Digital asset trading technology mainly includes online trading technology and offline trading technology. As a legal currency, digital assets should not be rejected by any unit or indivial, and can be traded online or offline. Online transaction technology realizes online transaction of digital assets through online device interaction technology, online data transmission technology and online transaction processing; The off-line transaction technology realizes the off-line transaction of digital assets through the off-line device interaction technology, off-line data transmission technology and off-line transaction processing technology. Finally, trusted guarantee technology is used to provide a safe and reliable application environment for the issuance, circulation and transaction of digital assets in blockchain. Digital asset trustworthiness assurance technology mainly refers to trusted service management technology. Based on trusted service management platform (TSM), it ensures the security and trustworthiness of digital asset security mole and application data, and provides security chip (SE) and application life cycle management function for digital asset participants. Trusted service management technology can provide application registration, application download, security authentication, authentication management, security evaluation, trusted loading and other services for digital assets, which can effectively ensure the security and credibility of digital assets system
what is blockchain? Blockchain technology, also known as distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, so that everyone can participate in database records. Blockchain technology development blockchain technology development what is a blockchain system? Blockchain system is a database system with integrity. The data written into the system will be automatically copied to the nodes of the blockchain, which can achieve transactional data preservation, support the management and development of databases in various instries, and be proced in combination with various needs. 294.497 billion US dollars, or 2.60%. This week, five new projects entered the top 100, namely FST, ZB, Wix, wax and MXM. On August 11, the price of bitcoin was $11523.58, up 3.20% from last week, and Ethereum was $216.09, down 3.86% from last week. The 24-hour turnover of this week increased by 2.63% over the same period last week; Among the top 100 projects, the total market value and average market value of currency projects increased significantly, and the classification composition of global blockchain assets top 100 projects was stable.

network virtual currency can be roughly divided into
the first category is familiar game currency.

the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third kind of virtual currency on the Internet, such as bitcoin (BTC), Fuyuan coin (FTC), Wright currency (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. Mainly used for Internet financial investment, can also be used as a new currency directly for life

basic system of futures

1. Position limit system

position limit system refers to the system that futures exchanges limit the number of positions held by members and customers in order to prevent manipulation of market prices and excessive concentration of futures market risks on a small number of investors. If the limit is exceeded, the exchange may close the position or increase the margin ratio

Large account reporting system means that when the speculative position of a certain type of position contract of a member or client reaches more than 80% of the position limit (including the principal) specified by the exchange, the member or client shall report its capital and position to the exchange, and the client shall report through the brokerage member

at present, the basic pattern of important foreign exchange in the world foreign exchange market is as follows:

the basic pricing relationship between most currencies is still dominated by the US dollar, and the international status of the US dollar is related to the strong development strength of the United States and the formation and development history of the international exchange rate system

The rapid development of Japan's economy and considerable strength have made the position of yen stable and expanded. Euro is a newborn. The strong momentum of the European area's unified policy and its internal economic strength determine that euro will become an important currency in the foreign exchange market dominated by US dollar and Japanese yen in the 21st century

In order to prevent foreign exchange risk, the central banks of Asian countries have controlled half of the world's foreign exchange reserves. Chinese mainland's foreign exchange reserves have been 3 trillion and 820 billion dollars, followed by China, Japan, Taiwan China and Hongkong. The growth trend of Asian countries is making the power balance pattern of the international monetary system develop in favor of Asia
