Method, node and system for executing intelligent contract, electronic device and storage medium

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. 本申请实施例提供了种智能合约的执行方法、节点、系统、电子设备及存储介质。该方法包
