Abstract

One or more embodiments of the present specification provide a blockchain-based private transaction method. The private transaction method based on the block chain is applied to node equipment of a trustable user and comprises the steps that a first message sent by the block chain user is received, and the first message comprises first data information which is not subjected to privacy protection;Converting the first data information which is not subjected to privacy protection into second data information which is subjected to privacy protection; Storing the first data information in a localdatabase of node equipment of the trusted user; And sending a second transaction to the block chain, the second transaction comprising the second data information, so that the second transaction is verified and recorded in a distributed database of the block chain.

Description

technical field [0001] This specification relates to the field of data processing technology, and in particular to a blockchain-based privacy transaction and its application method and device. Background technique [0002] Blockchain technology, also known as distributed ledger technology, is an emerging technology in which several computing devices jointly participate in "bookkeeping" and jointly maintain a complete distributed database. Due to the characteristics of decentralization, openness and transparency, each computing device can participate in database records, and fast data synchronization between computing devices, blockchain technology has been widely used in many fields. to apply. [0003] However, in the current mainstream blockchain architecture, each node saves the same data; in some practical scenarios, blockchain node participants do not want their data to be known by other nodes. Contents of the invention [0004] In view of the current situation and p...
