Abstract

The application discloses a data storage and query method and device based on a block chain. The method comprises the following steps: after receiving a service request sent by a user, a block chain node can resolve each data category and service data corresponding to each data category from the service request, and stores the resolved service data in a database corresponding to the block chain node according to a corresponding relation of the data category and the service data. By resolving the service data, the service data can be stored to the database corresponding to the block chain node according to the corresponding relation between the data category and the service data; therefore, the user can realize the query based on the corresponding relation in the database when querying the service data, a problem existent in the query based on the query in the existing block chain is avoided, the flexibility of the data query in the block chain is increased, and the data query efficiency is effectively improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a blockchain-based data storage and query method and device. Background technique [0002] With the continuous development of computer technology, blockchain technology (also known as distributed ledger technology) as a new distributed data storage technology, due to its non-tamperable characteristics, makes the data stored in the blockchain Data has the characteristics of notarization and credibility, which makes the use of blockchain technology more and more extensive. [0003] Specifically, the data storage principle of the blockchain can be understood as follows: a user initiates a business request through an Ethereum client (that is, a client that supports blockchain technology, also called a blockchain client). The Ethereum client can send the service request to the consensus network, and each blockchain node in the consensus network will agree on the service r...
