Problems solved by technology

Although the entire blockchain includes many nodes, the actual computing power of the entire network is equivalent to the computing power of one node. The existing execution method of smart contracts wastes a lot of computing resources
It can be seen that Bitcoin, Ethereum, etc. based on the smart contract mechanism execute smart contracts very slowly, and the transaction processing speed is very slow.

Abstract

Embodiments of the present application provide a method, node and system for executing an intelligent contract, an electronic device, and a storage medium. The method comprises the following steps: acontract execution node in a block chain executes an intelligent contract to be executed to obtain an execution result of the intelligent contract; the contract execution node generates zero-knowledgeproof information of the execution result, and the zero-knowledge proof information is broadcast to a verification node in the block chain, so that the verification node verifies the received zero-knowledge proof information, and it is determined that the intelligent contract is executed successfully when the verification is passed, wherein the verification node is a node other than the contractexecution node in the block chain. According to the scheme of the embodiment of the present application, the execution efficiency of the intelligent contract can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of smart contracts. Specifically, the present invention relates to a smart contract execution method, node, system, electronic device and storage medium. Background technique [0002] A smart contract is a computer protocol designed to disseminate, verify or enforce contracts in an informational manner. Smart contracts allow for trusted transactions without third parties, which are traceable and irreversible. Smart contracts are a method of security superior to traditional contracts and able to reduce other transaction costs associated with contracts. [0003] For example, for the blockchain, all users on the blockchain can see the smart contracts based on the blockchain. The existing smart contracts need to be executed once on all nodes of the blockchain, and the execution of all nodes When the number of nodes with identical results or identical execution results exceeds a certain number, the ex...
