Problems solved by technology

[0003] The purpose of the present invention is to provide a smart contract upgrade and compatibility method and system applied to the blockchain system in order to solve the problem of upgrading and compatibility of heterogeneous data in the current containerized deployment of smart contracts, which can be quickly, efficiently and fully automatically completed. The contract is upgraded without affecting the normal operation of the system. At the same time, the upgraded smart contract can automatically complete the data compatibility of the old contract to achieve seamless access

Abstract

The invention provides a smart contract upgrading and compatibility method and system applied to a blockchain system, relates to the field of blockchains, can be applied to the financial field and other fields, and the method comprises the steps: calculating and generating a hash value according to a smart contract code in an installation transaction request of a to-be-installed smart contract; compiling a smart contract code in the installation transaction request to construct a corresponding smart contract mirror image; registering and generating a contract record according to the intelligent contract mirror image and the hash value; and monitoring a contract state on the blockchain, when the contract state is updated, calling a corresponding intelligent contract mirror image according to the contract record to start a contract container, and performing transaction processing on the associated intelligent contract through the contract container.

Description

technical field [0001] The invention relates to the field of block chain, and can be applied to the field of finance and other fields, in particular to a smart contract upgrade and compatibility method and system applied to the block chain system. Background technique [0002] Smart contracts are an important module of blockchain service output. Business applications write business logic through smart contracts, and upload data to the chain after contract processing. Therefore, smart contracts are highly active and often need to be upgraded. When deploying contracts in a container In a blockchain system, smart contract upgrades usually require restarting the smart contract container. The upgrade solution is either complex in design and inefficient, or unfriendly to the application, affecting the normal operation of the system. In addition, smart contracts involve the processing of on-chain data, and each transaction will generate data related to the contract. After the contr...
