Abstract

The invention discloses a verification method and device based on a block chain smart contract, and relates to the technical field of block chains, and the method comprises the steps: receiving a verification request of a target smart contract, the target smart contract being a smart contract after repairing a first smart contract, and the verification request being a verification request of the target smart contract; the first smart contract is a wrong smart contract; according to the verification request, generating a target account and a target random number, the target account and the target random number being used for verification work of the target smart contract; and through the target account and the target random number, performing error reproduction on an error occurring in the first smart contract to verify the target smart contract. Through application of the method and the device, the problem that the verification efficiency is relatively low due to the fact that offline coordination needs to be carried out when the repaired smart contract is verified in related technologies is solved.

Description

technical field [0001] The present application relates to the field of blockchain technology, and in particular, to a verification method and device based on a blockchain smart contract. Background technique [0002] Blockchain (Block Chain) is a common accounting solution that uses cryptography to ensure access security, uses P2P communication technology to achieve peer-to-peer communication, uses consensus mechanism to achieve accounting legitimacy, and uses chain structure to store data. With the continuous expansion of blockchain applications, there are in-depth applications in finance, public services, product traceability and other fields. During the application process, various alliance parties will inevitably encounter production problems, and it is necessary to carry out targeted analysis and improve the technical implementation plan to fix the problem. This process is generally led by the alliance party who has repair needs, and is carried out in the informal oper...
