Embodiment 1

[0037] see figure 1 , this scheduling method can mainly achieve: external requests can be added by using the smart contract management interface to add timed tasks, and the timed tasks can be configured as a specified cycle or specified time point or specified time every minute or hour or every day or every week or every month or every year Execution requirements at intervals or specified times; tasks are classified and processed, and placed in the timing task processing queue; during the scheduling process, the node packages the timing tasks in new blocks, and broadcasts them to Other nodes in the blockchain enable all nodes to equally have the task processing capabilities of scheduled tasks; the event listener performs event monitoring, timeout monitoring, and processes eligible tasks, and then updates the task status, specifically including the following steps:

[0038] 1. The external request adds a scheduled task to the blockchain, configures the execution requirements of...

Abstract

The invention relates to the technical field of block chains, and specifically relates to a block chain intelligent contract timed task dispatching method. The method comprises: (1) adding a timed task, configuring execution requirement of the timed task, submitting the timed task to a block chain processing node; (2) performing classified processing on the timed task, and adding to a task processing queue; (3) selecting a consensus node of the block chain, the consensus node obtaining consensus permission; (4) when the timed task reaches the execution requirement, the consensus node performing task processing on the timed task; (5) after the task is processed, synchronizing the state of the timed task to other nodes, after other nodes obtain consensus permission, according to the state of the timed task, performing next task processing on the timed task which is not executed. The dispatching method is high in flexibility and accuracy, and can realize accurate time control, and can accurately and efficiently process tasks.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain smart contract timed task scheduling method. Background technique [0002] Blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order. It is cryptographically guaranteed to be non-tamperable and non-forgeable, and to realize a decentralized distributed ledger. . In the field of blockchain technology, due to its distributed, shared data blocks, cryptographic encryption, and other security strategies, the smart contract layer only provides limited program customization functions. In some business scenarios, such as data In terms of business processing such as regular processing, regular value exchange, and entrusted payment, the application of blockchain technology has encountered great difficulties. [0003] In order to solve these difficulties, the current mainstream solution is to design a centralized appli...
