Problems solved by technology

[0003] In the existing smart contract management technology, the life cycle of the smart contract is not complete. In the blockchain network deployed using k8s, the chain code is often stored inside the network. When the contract is installed, it will be too dependent on the hardware of the endorsement node. Coded contract construction logic makes contract updates inflexible

Abstract

The invention provides a method and system for realizing intelligent contract life cycle management based on an external chain code container. The method specifically comprises the steps of: initiating, by a certain organization in a channel, a proposal request for operating an intelligent contract, wherein the operation on the intelligent contract comprises deployment, upgrading, freezing, unfreezing, version rollback, version advancing and parameter upgrading of the intelligent contract; if the proposal is successfully initiated and approved by voting, executing the proposal, and performing installation and instantiation operation of the related intelligent contract, wherein the intelligent contract runs in an external chain code container after being installed, and does not depend on contract construction logic of endorsement node hard coding any more, and high availability of chain codes is guaranteed. According to the invention, a complete life cycle is provided for intelligent contracts, so that an organization in a channel can better manage intelligent contract in real time for a specific business and complete business-related logic.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a method and system for realizing smart contract life cycle management based on an external chain code container. Background technique [0002] In the blockchain network, multiple organizations complete the relevant logic of a certain business by executing smart contracts (that is, a piece of chain code). Since an organization can join multiple channels, and there are many types of business completed when there are transactions between organizations, it is often necessary to deploy multiple smart contracts in the channel according to needs, so the management of smart contracts is very important. [0003] In the existing smart contract management technology, the life cycle of the smart contract is not complete. In the blockchain network deployed using k8s, the chain code is often stored inside the network. When the contract is installed, it will be too dependent on th...
