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

Abstract

The invention provides an intelligent contract version management method and device and a readable storage medium. The management method comprises the steps of receiving a first transaction which is created according 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 proportion rule table in a storage space corresponding to the contract address, wherein the contract code table comprises a contract code and a versioncode name which are in a mapping relationship, and the proportion rule table comprises a proportion number, a version code and a transaction flow proportion which are in a mapping relationship; receiving a second transaction created according to the contract address and the calling parameter, and obtaining a corresponding proportion rule table according to the contract address; and determining a version code according to the proportion rule table so as to execute a second transaction according to the contract code corresponding to the version code. The beneficial effect of the invention is that the method achieves the multi-contract code version management based on a 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 that can safely store digital currency transactions or other data, information cannot be forged and tampered with, and transaction confirmation on the blockchain is shared by all nodes on the blockchain Completed, the consensus algorithm guarantees its consistency. A public ledger is maintained on the blockchain. 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 thro...

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
