Problems solved by technology

During the development process, if the chain code corresponding to the blockchain database is changed, the SDK code needs to be adjusted frequently during the development process (for example, new chain code functions are added, chain code parameters are changed), and the entire development process is relatively cumbersome

Abstract

The invention provides a calling method and device based on a block chain, electronic equipment and a storage medium. The method comprises the steps that calling parameters are determined according to a target resource address carried by a calling request, and the calling parameters comprise function parameters and operation modes; when the operation mode is a first mode, querying a cache database to obtain a first chain code result corresponding to the function parameter; under the condition that the operation mode is a second mode, executing a target chain code according to the calling parameter and a preset software development kit to obtain a second chain code result, and updating a first chain code result corresponding to the function parameter in the cache database based on the second chain code result; and sending the first chain code result or the second chain code result to a terminal based on the target resource address.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a calling method, device, electronic equipment and storage medium based on block chains. Background technique [0002] Blockchain can be regarded as a special distributed ledger technology, which cryptographically ensures that its data cannot be tampered with. The characteristics of blockchain such as "decentralization", "non-tamperability", and "openness and transparency" are widely used in data storage scenarios. A large number of enterprises have begun to store data in blockchain-based databases, building applications and systems based on this, and improving the security and convenience of data storage. [0003] In the existing process of developing and building blockchain applications, the process of operating (adding, deleting, modifying) the blockchain database is relatively cumbersome, such as the commonly used alliance chain system Hyperledger Fabric. When d...
