Technical Field
The invention relates to the technical field of block chains, in particular to a user communication platform based on an alliance block chain.
Background
The block chain is a distributed account book which combines data blocks in a sequential connection mode into a chain data structure according to a time sequence and is guaranteed to be not falsifiable and counterfeitable in a cryptographic mode. The block chain has the greatest advantage of decentralization, and point-to-point transaction based on decentralization credit is realized in a distributed system with network nodes not needing mutual trust by applying technologies and methods such as cryptography, a consensus mechanism, game theory and the like. Digital currency is by far the most successful blockchain application scenario. Among them, bitcoin and ether house are typical representatives of digital currency and its trading platform. The block chain can be applied to the field of digital encryption currency, and has wide application scenes in 6 fields of financial services, supply chain management, cultural entertainment, social public welfare, government management and the like.
The existing communication modes in China mainly comprise: the mobile phone numbers distributed to users based on three operators are used for real-time communication; the user utilizes various communication software to carry out video, voice and text communication; the user utilizes various information communication platforms to communicate. The existing communication modes all belong to a centralized management mode, all user information and communication information are stored in a third-party database, and if various safety problems occur in the database, user privacy information can be leaked. There are many drawbacks to the application of the existing block chaining technique, such as delay: in the current mainstream blockchain application, bitcoin, the process of generating blocks and getting the confirmation takes about 10 min. Instant messaging occupies a main position in the communication process of users, and the communication quality is seriously influenced by too high time delay.
