Title:
BLOCKCHAIN DATA PROCESSING METHODS, APPARATUSES, DEVICES, AND SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2019/217598
Kind Code:
A8
Abstract:
Implementations of the present specification disclose blockchain data processing methods, apparatuses, devices, and systems. In an implementation, blockchain transaction data of a plurality of transaction participants is received, each of the plurality of transaction participants providing a respective certificate indicating a respective legal membership in a blockchain network, the respective legal membership enabling processing of the blockchain transaction data. Mutual identity querying is performed to confirm whether each of the plurality of transaction participants have the respective legal membership in the blockchain network. Supervision keys of a supervision node in the blockchain network are determined, where the supervision node corresponds to a supervisor and the supervision keys are dynamically updated based on a predetermined rule. The blockchain transaction data is encrypted by using the supervision keys. The blockchain transaction data is then stored.
