Abstract

The invention provides a hyperledger-based data collection method and device, a computer system, a computer readable storage medium and a computer program product, which can be applied to the technical field of block chains or other fields. The method comprises the steps that an on-chain request sent by a client to a block chain system is collected, the on-chain request is used for requesting to acquire target data, and the block chain system is pre-deployed with the following intelligent contracts: a query contract, an order matching contract and an oracle machine contract; and in response to the on-chain request, calling a target intelligent contract according to the execution sequence of the intelligent contract to obtain target data, wherein the execution sequence comprises the steps of firstly executing the query contract or the order matching contract, and after the query contract or the order matching contract is executed, under the condition that a result used for representing target data collection failure is returned, executing the oracle machine contract so as to acquire the target data from the oracle machine network.

Description

technical field [0001] The present disclosure relates to the technical field of blockchain, and more specifically, to a data acquisition method, device, computer system, computer-readable storage medium and computer program product based on a hyperledger. Background technique [0002] Hyperledger Fabric (super ledger) is an alliance chain development platform. The Hyperledger fabric consortium chain is an open source project under the Linux Foundation. It promotes cross-industry collaboration by developing blockchain and distributed ledger applications using modular frameworks such as consensus mechanisms, underlying storage, identity authentication, and access control. [0003] In the process of implementing the disclosed concept, the inventors found at least the following problems in related technologies: Due to the limitations of the blockchain protocol itself, the applications or smart contracts built on it cannot interact with external content simply and efficiently , ...
