Abstract

The invention discloses a smart contract upgrade method, a smart contract upgrade system, related equipment, and a storage medium and belongs to the blockchain technological field. The smart contractupgrade method includes the following steps that: a blockchain node sends an upgrade request to a smart contract release center; the blockchain node receives an upgrade response containing encrypted data which is returned by the smart contract release center, wherein the encrypted data include smart contract data of a target version; the blockchain node verifies the data in the upgrade response; and the blockchain node performs upgrade with the smart contract data of the target version in response to the pass of the verification. With the smart contract upgrade method, the smart contract upgrade system, the related equipment, and the storage medium provided by the embodiments of the present invention adopted, the blockchain node sends the upgrade request to the smart contract release center so as to obtain the smart contract data of the target version; the blockchain node verifies the smart contract data of the target version, and performs upgrade; and therefore, the safe and automaticupgraded of a smart contract is realized, and the efficiency and security of the upgrade of the smart contract can be improved.

Description

technical field [0001] The present invention relates to the technical field of block chain, in particular to a smart contract upgrade method, system, related equipment and storage medium. Background technique [0002] Since the blockchain itself has the characteristics of anti-tampering and traceability, blockchain technology is increasingly used in data storage. A smart contract is an executable code stored in a blockchain node, which specifies the execution process and processing logic of the smart contract, such as input, output, intermediate conversion logic, and so on. After analysis, the inventor found that with the optimization of the processing logic of the smart contract, it is inevitable to upgrade the smart contract during use. At present, the smart contract is mainly upgraded manually. Contents of the invention [0003] After analysis, the inventor found that the upgrade of the smart contract not only involves the upgrade of a local node of the blockchain, bu...
