Problems solved by technology

[0005] However, in the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: in real life, the point-to-point transaction amount between users (enterprises or individuals) generally has confidentiality requirements, and the total balance of users in the system also has Confidentiality needs
Traditional centralized solutions can easily set data access rights without cooperative bookkeeping, which can solve the privacy problem well, but users still hope to use the advantages of distributed technology such as blockchain to store multi-party data. Other documents and data for cooperation, but a complete closed business loop requires funds to participate in real-time clearing and settlement, which leads to the problem that cooperation sharing and transaction privacy cannot coexist

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a transaction method and device based on digital currency. Background technique [0002] Blockchain is a new type of distributed technology. Protocol makers formulate and publish rules before the system runs, and develop clients that follow the protocol. Afterwards, multiple institutions or individuals act as nodes to connect and run the system. On the client side, the data generated by malicious nodes that do not conform to the agreement will be discarded by other honest nodes. This method of confrontational consensus is used to jointly maintain a general ledger, so that no centralized authority or individual can tamper with the initial agreement. imagine.
