Problems solved by technology

Although the public chain technology supports smart contracts, as long as the smart contracts are deployed, anyone can participate in the relevant operations of the smart contracts, and the contract logic cannot be modified or upgraded
Compared with the public chain technology, although the alliance chain technology is more suitable for the business requirements related to the enterprise-level alliance chain, it can only modify the logic of the smart contract through a rather cumbersome upgrade operation.
All in all, neither the existing public chain technology nor the existing alliance chain technology can support the simple and convenient modification of the internal logic of the smart contract after the deployment of the smart contract

Abstract

The invention discloses a block chain intelligent contract modification method and device and a computer readable storage medium, and the method comprises the steps: firstly, receiving a modified first transaction verification rule which comprises member signature information; secondly, broadcasting the first transaction verification rule in a block chain, and carrying out legality verification onthe member signature information; therefore, when the member signature information is legal, the first transaction verification rule is used as a variable to be stored in the smart contract of the block chain. According to the block chain intelligent contract modification method provided by the embodiment of the invention, the transaction verification rule is stored as a variable, the transactionverification rule can be conveniently modified at any time and only needs to be modified once, upgrading operation on each node is avoided, and the efficiency of block chain intelligent contract modification is improved.

Description

technical field [0001] The present invention generally relates to the field of information technology, and specifically relates to a blockchain smart contract modification method, device, and computer-readable storage medium. Background technique [0002] Blockchain (Block chain) is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and encryption algorithm. In essence, the blockchain is a decentralized database that can safely store transaction data, information cannot be forged and tampered with, and smart contracts can be flexibly issued and executed without any audit by a centralized organization. Among them, the transaction can be not only a digital currency like Bitcoin, but also digital assets such as debt, equity, copyright, etc. Because the blockchain technology solves the Byzantine general problem well, it greatly reduces the trust cost and accounting cost in the real economy, thus redef...
