Smart contract version management method and device, and readable storage medium

Abstract

The invention provides a smart contract version management method and device and a readable storage medium. The management method comprises the steps of receiving a first transaction which is createdaccording to a contract code and a deployment parameter and is used for deploying an intelligent contract, generating a contract address of the intelligent contract according to the first transaction,and storing a contract code table and a condition rule table in a storage space corresponding to the contract address, wherein the contract code table comprises a plurality of contract codes and version codes in a mapping relationship, the condition rule table comprises a plurality of condition rules, each condition rule comprises a version code, a condition combination mode and a condition listwhich are in a mapping relationship, and each inspection condition is recorded in the condition list; receiving a second transaction which is created according to the contract address and the callingparameter and is used for calling the intelligent contract, and obtaining a corresponding condition rule table according to the contract address; and determining a version code according to the condition rule table so as to execute a second transaction according to the contract code corresponding to the version code. The smart contract version management method and device have the beneficial effect that the multi-contract code version is managed based on the single contract address.

Description

technical field [0001] The present invention relates to the technical field of block chains, and in particular to a management method, device and readable storage medium of an intelligent contract version. Background technique [0002] Blockchain technology, blockchain is a new type of decentralized protocol, which can safely store digital currency transactions or other data. The transaction confirmation on the blockchain is completed by all nodes on the blockchain and guaranteed by the consensus algorithm. For its consistency, a public ledger is maintained on the blockchain, and the public ledger is visible to any node on the storage block, thus ensuring that it cannot be forged and tampered with. [0003] Smart contracts, smart contracts on the blockchain refer to a string of binary codes written and compiled by solidity and run on the blockchain. We can implement data storage, reading and writing, and some logic on the blockchain through smart contracts. Operation, so so...

Problems solved by technology

However, in the process of management and maintenance of smart contracts, the code changes of smart contracts are all hard changes. Before the contract code is changed, all contract users use the smart contract before the change. After the contract code is changed, all contract users use the changed smart contract. , lacking a management method to smoothly switch code versions between old and new smart contracts
