[0028]According to the applicant's research, it is found that the existing smart contract is a computer protocol designed to propagate, verify or execute contracts in an informationized manner. Smart contracts allow trusted transactions without a third party, these transactions are traceable and irreversible, which can provide a security method superior to traditional contracts and reduce other transaction costs associated with contracts. Because smart contracts are codes, different from paper contracts, smart contracts have extremely high requirements for code accuracy. If the smart contract is written incorrectly, it will lead to transaction failure or even loss of ether, wasting a lot of manpower, material resources and time. Therefore, smart contracts need The debugger is used to debug the code to ensure that the operator can quickly and accurately find the error and solve it when an error occurs. However, the existing smart contract debuggers, for example, the Remix built...

Abstract

The invention provides a smart contract debugging method, device and storage medium thereof, and relates to the technical field of smart contract debugging. The smart contract debugging method includes: obtaining the operation code OpCode instruction of the smart contract; determining the replacement instruction function corresponding to the OpCode instruction through the OpCode interpreter; converting the operation function in the replacement instruction function into a symbol variable function; After the replacement instruction function is executed, the smart contract is debugged based on the execution result of the replacement instruction function. The intelligent contract debugging method can debug the intelligent contract without the source code of the intelligent contract and the specific transaction value of the blockchain.

Description

technical field [0001] The present invention relates to the technical field of smart contract debugging, in particular to a smart contract debugging method, device and storage medium. Background technique [0002] Smart contracts are an idea proposed by Nick Szabo in the 1990s, almost at the same age as the Internet. Due to the lack of a credible execution environment, smart contracts have not been applied to the actual industry. Since the birth of Bitcoin, people have realized that the underlying technology of Bitcoin, blockchain, can inherently provide a credible execution environment for smart contracts. Ethereum First saw the fit of blockchain and smart contracts, released the white paper "Ethereum: Next Generation Smart Contract and Decentralized Application Platform", and has been committed to making Ethereum the best smart contract platform, so Bitcoin leads Blockchain, Ethereum revives smart contracts. [0003] As one of the current hot topics, smart contracts have...
