Problems solved by technology

[0003] Although there are many automated tools to ensure the specification of the contract and a large number of tests, the troubleshooting in the test and the repair of the contract problem are mainly completed by manually checking the contract execution log. The accuracy of the contract execution is also dependent on manual labor, which will cause two problems: First, the development and operation and maintenance of smart contracts are costly. The contract itself must be deployed to execute transactions on the network before it can be tested. If there is an execution error or the result is wrong during the test, the contract execution log can only be manually checked to find the error message. Troubleshoot code problems and fix them; second, the logical accuracy of smart contracts cannot be guaranteed. Contract codes are a collection of business logic, and the integrity of transaction links on the chain cannot be tracked in real time. Logical loopholes can only be discovered passively during account reconciliation or error reporting. And the link is not clear, making it difficult to reproduce the problem

Abstract

The invention provides a block chain intelligent contract repairing method and device, and belongs to the technical field of block chains. The block chain smart contract repair method comprises the steps of uploading a smart contract to a block chain test network, so that the block chain test network executes the smart contract and generates an operation log; receiving an operation log from the block chain test network, and generating an actual service flow chart according to the operation log; comparing the actual business flow chart with a corresponding preset business flow chart to generate a repair code; and repairing the smart contract according to the repair code. The development, operation and maintenance cost of the smart contract can be reduced, and the accuracy of the internal logic of the smart contract is improved.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a method and device for repairing block chain smart contracts. Background technique [0002] Smart contracts can only be tested on their functional interfaces by deploying them on the blockchain network. The test is generally implemented by writing automated test cases and performing a large number of input and output checks. Many companies currently provide static code scanning of smart contracts And formal verification methods constrain the writing specifications of smart contracts. [0003] Although there are many automated tools to ensure the specification of the contract and a large number of tests, the troubleshooting in the test and the repair of the contract problem are mainly completed by manually checking the contract execution log. The accuracy of the contract execution is also dependent on manual labor, which will cause two problems: First, the developme...
