Abstract

The invention provides a bidding method for an oracle machine service based on a block chain. The method comprises the steps that S100, a data subscription demander sends an SLA service level agreement for ordering an oracle machine to an oracle machine order distribution contract through an oracle machine service ordering client; s200, the oracle machine order distribution contract creates a latest SLA record according to the selected oracle machine information and triggers a log file to inform the selected oracle machine; s300, after the selected oracle machine monitors the order informationon the chain, a response operation is started, and a required data result is calculated and sent to an oracle machine data receiving contract; and the oracle machine data receiving contract providesthe received demand data result to the demand side intelligent contract. The oracle machine in the distributed oracle machine network participates in project competition in a bidding mode, a multi-dimensional objective oracle machine evaluation system can be provided for users, and meanwhile the authenticity and safety of data are improved.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a bidding method and system for oracle service based on block chains. Background technique [0002] The blockchain is a closed environment, and the chain cannot actively obtain real-world data outside the chain. The main reason is that the blockchain cannot actively initiate a Network call (network call) and the smart contract on the chain receives data passively. Secondly, the smart contract is not actually "smart", it is only a program that reaches the trigger state when the corresponding conditions are met. At the same time, the final execution of the smart contract requires the signing of the private key of the contract participants, and the smart contract itself cannot be automatically executed. When the triggering conditions of the smart contract depend on the information outside the blockchain, the information needs to be written into the records in the blockchain f...
