Abstract

The invention discloses a block chain private transaction multistage consensus method and device, and a storage medium, which are used for an alliance chain system composed of a plurality of businessdistricts; interconnection between different business districts is realized through a certain public node, and data in the business districts is only shared by node plaintexts in the business districts. When a certain business district node receives the data of the application service, firstly, the data is subjected to data consensus in the business district node receiving the data. And after thedata consensus is completed, the public node in the business district encrypts plaintext data and sends encrypted hash data to the nodes in other business districts, and the nodes prove the correctness of the verification data through zero knowledge. And data verification is finished at each node to complete the whole consensus process of the alliance chain. According to the method, consensus among alliance chain nodes can be realized while commercial district private data is ensured, the complexity of a chain node network is simplified by a multi-stage consensus mechanism, and the efficiencyof alliance chain consensus is improved.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a multi-level consensus method, equipment and storage medium for block chain privacy transactions. Background technique [0002] The essence of blockchain technology is a special distributed ledger technology, which collectively maintains distributed and stored trusted data in a decentralized or multi-centralized manner, and provides a way to conduct trusted information in an environment without the witness of an authoritative center. Mechanism of exchange with value transfer. The consortium chain is a chain composed of a group of specific group members or limited third parties, and the nodes of the consortium chain are maintained by each member. The emergence of the alliance chain not only breaks the problem of data islands between different enterprises, but also enriches the application scenarios of the blockchain. However, with the deepening of scenario applications, th...
