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.

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

network virtual currency can be roughly divided into
the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade 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

a real digital currency should have the following points:
1. It can be traded on the digital currency trading platform
2. The information of operation team is open and transparent
3. Have a good application scenario planning
4. It is a digital cryptocurrency developed based on blockchain technology
5. The source code is transparent and can be viewed by anyone
it is obvious that the so-called Kyushu digital currency does not have these conditions and is naturally different from bitcoin, Ruitai currency, Qianjin card and other digital currencies.
