Abstract

The invention discloses a chain code upgrading method and device, and relates to the technical field of block chains. The method comprises the following steps: the endorsement node Endorse acquires afirst target version set corresponding to the chain code Chaincode to be upgraded; and performs simulation upgrading on the to-be-upgraded chain code according to the first target version set in the independent operating environment, and if the second world state World State of the first target version set is consistent with the first world state, the to-be-upgraded chain code is updated by the endorsement node outside the independent operating environment.The first target version set comprises an upgrade package of the first target version, related configuration of the upgrade package and anindependent operation environment, the independent operation environment does not affect the operation environment except itself, the first world state is the world state of the to-be-upgraded chain code before simulation upgrade, and the second world state is the world state of the to-be-upgraded chain code after simulation upgrade.

Description

technical field [0001] The present application relates to the technical field of blockchain, and in particular to a chain code upgrade method and device. Background technique [0002] In blockchain technology, all participating nodes jointly verify each transaction, and each node stores the ledger of the transaction, so that the two parties who have reached an agreement can directly conduct transactions without third-party endorsement. Specifically, the chain code is used to indicate the logic of the transaction and the rules of transaction processing. By executing the chain code, the node will include at least one transaction (including the payer and payee of the transaction funds, the amount of the transaction funds, etc.) In the block, the block is used as an account page. The transactions existing in the blockchain network can be recorded in multiple blocks, and each block is connected together in a certain order to form a blockchain. The formed blockchain is also the r...
