Embodiment Construction
[0027] The method for timing trigger calling of a system contract based on blockchain technology of the present invention mainly includes: a blockchain system supporting smart contracts, a system contract code, and an execution system of the system contract. The system contract defines content such as subscription, trigger cache, automatic execution entry, and substitution execution. The execution system of the system contract will be implemented in the bottom layer of the blockchain. At the specified time (block number), a call to the automatic execution entry of the system contract is initiated, so as to trigger the call to the subscribed contract.
[0028] The described system contract is automatically executed in each block and each node of the blockchain system. The specific code of the system contract is imported into the blockchain system in the genesis block or the block set by the blockchain system. take effect. The execution subsystem of the system contract and the co...
