Problems solved by technology

[0003] (1) In the blockchain network, the distributed ledger data of each node is stored on a server, and all data must be verified on the server of each node before it can be stored persistently. The performance requirements are extremely high, which brings certain performance bottlenecks to large-scale data applications
[0004] (2) The underlying persistent storage of blockchain distributed ledger data basically adopts open source NOSQL products, lacking independent monitoring, operation and maintenance of the data storage layer, and a distributed operation and maintenance mechanism for the database
[0005] (3) From the analysis of the architecture, the database is integrated on the transaction node of the blockchain, the database and the verification node are highly coupled, and the database is deployed on a ...

Abstract

The invention provides a data storage method, device and system based on a blockchain. The data storage system based on the blockchain comprises a transaction server which is used for performing a transaction according to an intelligent contract and a consensus mechanism and obtaining blockchain data; a database server routing and configuration unit which is used for dynamically configuring and routing a database server and obtaining a target database server, wherein the target database server is used for storing the blockchain data; a storage model calling unit which is used for calling a corresponding database access protocol from a uniform database drive interface of various database protocols and calling a corresponding storage model from a target database; and the database server which is used for storing the blockchain data to a database in the storage model and/or a data table.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a data storage method, device and system based on blockchain. Background technique [0002] As an innovative technology architecture born with Bitcoin, blockchain technology is essentially an open, transparent, tamper-proof, and traceable distributed ledger technology. As the industry's research on blockchain technology application scenarios deepens, its application scale will inevitably increase, and blockchain data will become larger and larger. At present, the NOSQL non-relational database used for blockchain data storage is deployed on each transaction node, which makes the storage function and transaction function highly coupled. This leads to the following problems: [0003] (1) In the blockchain network, the distributed ledger data of each node is stored on a server, and all data must be verified on the server of each node before it can be stored persistently....
