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...

Abstract

The invention discloses a timing system contract triggering and calling method based on blockchain technology, and relates to the technical field of intelligent contracts; and a system contract is executed automatically by each node of each block. A user subscribes the system contract to register a transaction executed in the future or call the contract. The registered contract is called in certain block in a determined way loyally via the system contract. The whole system comprises a blockchain system supporting intelligent contract, system contract codes and a system contract execution system. The system contract defines contents including subscription, buffer memory triggering, an automatic execution inlet and substituted execution. The system contract execution system is realized in the bottom layer of the blockchain. Thus, calling of the automatic execution inlet of the system contract is initiated in a specified time point, and the subscribed contract is triggered and called.

Description

Technical field [0001] The invention relates to the technical field of block chains, in particular to a method for calling smart contracts. Background technique [0002] The smart contract of the blockchain defines many functions to realize various functions. The calls to the functions of these smart contracts are all direct calls, using transactions to trigger contract calls to execute the calls to the contract. However, in many cases, it is necessary to limit the execution of the contract within a limited time frame. In addition, more importantly, whether the execution of the contract can be automatically triggered at a certain point in the future. The main shortcomings of the existing technology: [0003] 1) The execution of the contract execution must be executed through an explicit call. [0004] Because only transactions can trigger the implementation of contract functions, a transaction must be submitted to the blockchain system to implement the function call. [0005] 2) Th...
