Abstract

The invention relates to the technical field of data storage, in particular to a data storage method and device based on a block chain, equipment and a storage medium. The data storage method based onthe block chain comprises the following steps: obtaining transaction data of any client, generating a transaction data packet, carrying out statistics on the data volume in the transaction data packet, and creating a block corresponding to the client according to a statistical result; obtaining to-be-stored transaction data of at least one client, and generating a to-be-stored transaction data sequence from the to-be-stored transaction data according to the generated time sequence; extracting an identifier of a client carried in the to-be-stored transaction data, and writing the to-be-storedtransaction data sequence into a block corresponding to the client according to the identifier of the client; And endowing each block with a key value, and writing the to-be-stored transaction data inthe block into a key value database according to the key value. According to the technical scheme, the data storage efficiency is improved, the data is not easily tampered, and the source of the datacan be quickly and effectively found when the historical data is traced.

Description

technical field [0001] The present application relates to the technical field of data storage, and in particular to a blockchain-based data storage method, device, device, and storage medium. Background technique [0002] Blockchain is generally understood as a distributed ledger, which is essentially a distributed computing and storage system. The blockchain has multiple nodes. Different nodes reach a consensus through certain calculation rules, and store the transaction execution results after consensus in the database in the form of blocks. Multiple blocks form a blockchain. Multiple nodes Blocks can be backed up by each other. [0003] When applying blockchain for data storage, it is mainly based on BASE theory and CAP theory for distributed storage of data, decentralization, and comprehensive analysis of data consistency, availability and partition tolerance. Users set private keys or public keys to restrict the use of data according to their own needs. [0004] Howe...
