Abstract

The invention discloses a data processing method and device based on a block chain, and the method comprises the steps: receiving a plurality of pieces of operation data from a plurality of data chains in the block chain, with the operation data comprising operation execution sequence information and operation basic information; sequentially storing the plurality of job data in a local database according to the job execution sequence information, wherein the local database has an index set in advance according to the job basic information; and sending the corresponding job data to a subscription mechanism producer according to a predetermined subscription mechanism so as to forward the job data to a corresponding subscription mechanism consumer. The query requirements of different job datacan be met, and the query efficiency can be improved through the indexes set based on the basic job information.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a block chain-based data processing method and device. Background technique [0002] At present, after the blockchain is put into production and application, one of the biggest problems it faces is the query problem. The original blockchain provides various transaction and block data query interfaces, but these queries are basically based on the key-value (health-value) database stored in the blockchain, and based on the block height, ID ( Identity document, identity number), transaction ID and other elements are used as KEY (Kin) to query. [0003] However, the above query methods cannot satisfy the query of all business data, especially when multi-dimensional auditing and retrieval operations are performed, the above query methods cannot meet the query requirements. Contents of the invention [0004] In view of this, the present invention provides a blockchain-based d...
