Abstract

The invention provides a method, device and system for realizing contract updating. The method comprises the steps of after receiving a contract updating broadcast by the node in the block chain, extracting a contract signature from the contract updating broadcast; on the condition that the contract signature is verified successfully, extracting the contract codes and updating parameters from thecontract signatures; and generating a contract address according to the contract code, inserting the contract address into the contract code storage structure, thereby establishing a mapping relationship between the contract address and the contract code, and initializing the contract data storage structure by utilizing the updating parameters to establish parameter mapping, thereby realizing thecontract updating. According to the contract storage structure design based on the mapping table, the flexible expansion of the contract and the parameter structure is achieved, the nodes are correspondingly divided according to functions, and therefore the safe and automatic updating of the contract is achieved, and the updating process of the intelligent contract is greatly simplified.

Description

technical field [0001] The present disclosure relates to the Internet field, and in particular to a method, device and system for implementing contract renewal. Background technique [0002] As one of the most vital technologies in block technology, smart contracts solidify the execution of business rules recognized by both parties in the block chain through smart contracts, and automatically execute and record the execution status to avoid disputes and fraud, reduce trust costs, and improve transaction efficiency. A smart contract is essentially a piece of programmed code that runs on the blockchain, and all participants jointly ensure that its code and operating results are recognized by everyone. Due to security and implementation constraints, once a contract is deployed to generate a one-time address, the contract code cannot be changed. [0003] The existing smart contract update method is mainly through the deployment of routing contracts and functional contracts. Th...
