Abstract

The invention discloses a blockchain-based smart-contract calling method and device and a readable storage medium. The method includes the steps of: after a transaction request which is sent by a client and is of calling a smart contract in a blockchain is received, obtaining, according to the transaction request, a name of the smart contract and a calling interface of calling the smart contract;obtaining transaction parameters in the transaction request, and calling the smart contract according to the name and the calling interface; and executing a service, which corresponds to the transaction request, in the smart contract according to the transaction parameters to obtain a transaction result, and returning the transaction result to the client. According to the method, a calling processof calling the smart contract in the blockchain is simplified, and calling difficulty of the smart contract is reduced.

Description

Technical field[0001]The present invention relates to the technical field of block chains, and in particular to a method, equipment and readable storage medium for invoking smart contracts based on block chains.Background technique[0002]In the existing blockchain technology, the use of smart contracts generally includes writing smart contracts, compiling smart contracts, and publishing smart contracts, where each smart contract also corresponds to a set of contract interface description information. When the smart contract is released to the blockchain, the smart contract will generate an address. In the process of invoking a smart contract, it is necessary to combine the address and interface description information of the smart contract to successfully invoke the smart contract. The address of the smart contract is a magic number that is irregular and has no specific meaning. Therefore, the address is not convenient for blockchain identification and storage. If the blockchain lose...
