Problems solved by technology

This makes the external data input into the smart contracts of each node inconsistent, resulting in inconsistent output results of the smart contracts of each node. In this case, if each node cannot reach a consensus, the trust foundation of the entire blockchain network will collapse. As a result, the entire blockchain network cannot be trusted and stable

Abstract

The invention relates to a method and device for calling external data by an intelligent contract, a storage medium and electronic equipment, and the method is applied to a blockchain node in a blockchain network, and comprises the steps: obtaining the external data through the intelligent contract of a target business participation node, and broadcasting the obtained external data to other business participation nodes of a target business; under the condition that external data acquired by other service participation nodes of the target service is received, calculating to obtain to-be-consensus data of the target service participation node according to a preset rule based on all the external data; broadcasting the to-be-consensus data to other service participation nodes of the target service; determining consensus data from all the to-be-consensus data under the condition that the to-be-consensus data calculated by other service participation nodes of the target service is received;and inputting the consensus data into the intelligent contract of the target business participation node to enable the intelligent contract to execute corresponding operation. Therefore, the input data of the intelligent contracts of the business participation nodes can be consistent.

Description

technical field [0001] The present disclosure relates to the technical field of blockchain, and in particular, relates to a method, device, storage medium and electronic equipment for calling external data by a blockchain smart contract. Background technique [0002] Blockchain technology is also known as distributed ledger technology, which covers computer technologies such as peer-to-peer networks, consensus mechanisms, cryptography, and smart contracts. Blockchain provides a safe and trusted channel and trusted collaboration mode for information transmission in an untrusted competitive environment. [0003] Among them, the blockchain smart contract is a protocol that implements business logic through code, deploys and runs on the blockchain network nodes after compilation, and is used to complete the conditional triggering and automatic execution of the established rules, as well as perform corresponding book data operations. . The purpose of the blockchain from one sta...
