Problems solved by technology

First of all, smart contracts are executed in memory as a whole, resulting in a large memory footprint, that is, more resources; second, a single node runs independently without a scheduling management mechanism, so it is risky and vulnerable to attack from an overall perspective; third , the contract operation must be realized on the blockchain, and the contract operation is not separated from the blockchain. Once an abnormal problem occurs in the contract operation, it will affect the normal operation of the blockchain to a certain extent

Abstract

The invention relates to a task scheduling execution method and device based on smart contracts. The task scheduling execution method comprises a scheduling table construction step, wherein multiple smart contracts are inserted into a block chain, contract tasks are generated based on the smart contracts inserted into the block chain, and the contract tasks are used to construct a scheduling table; a to-be-executed queue construction step, wherein the contract tasks in the scheduling table are encapsulated, and the encapsulated contract tasks are used to construct a to-be-executed queue; and an execution step, wherein the encapsulated contract tasks in the to-be-executed queue are sequentially executed according to the order in the to-be-executed queue. According to the task scheduling execution method and device based on the smart contracts, the execution efficiency of the smart contracts can be improved, and the risk resistance ability can be enhanced.

Description

technical field [0001] The present invention relates to the technical field of smart contracts, and more specifically, to a method and device for scheduling and executing tasks based on smart contracts. Background technique [0002] A smart contract is a collection of code and data, also called a "programmable contract". Generally speaking, smart contracts are defined through program code, and various execution conditions are preset; when the execution conditions are triggered, various defined behaviors are executed. The "intelligence" is the intelligence in execution, that is to say, if a preset execution condition is met, the contract will be executed automatically. [0003] In the existing technology, the smart contract is executed in memory as a whole (which can be realized by the entire code). For application scenarios involving multiple nodes, smart contracts are executed independently on each node, and each node usually only monitors and / or maintains its own smart c...
