Abstract

Disclosed are an update method, system, device and equipment for an intelligent contract. When the smart contract in the blockchain system needs to be updated, the expected update conditions are agreed among the nodes, and each node determines its own preparation status before the update, thus ensuring the synchronous update of the new smart contract on each node.

Description

technical field [0001] The embodiments of this specification relate to the field of information technology, and in particular to a smart contract update method, system, device, and equipment. Background technique [0002] Blockchain application scenarios are becoming more and more abundant, and more and more scenarios need to complete business logic by writing smart contracts. With the continuous development of business scenarios, smart contracts need to be released and updated frequently. At present, the contract update generally adopts the traditional release mode directly. After the new contract is released, the blockchain nodes use the new smart contract code. [0003] During the release process, the release time of each node may be different. During the release period, a transaction may be the result of the execution of two different smart contracts, new or old, on different nodes. There may be inconsistent results, which is easy Lead to block chain bifurcation or con...
