Embodiment 1

[0019] A highly reliable data acquisition method based on blockchain oracles, the specific steps are as follows:

[0020] (1) In the process of nodes requesting to obtain data, the decentralized exchange needs to call the price of a token in the entire network to price the transaction, and send a data request to the oracle network through the corresponding blockchain node, and the oracle After each oracle in the network (assuming that the entire oracle network consists of 20 oracles) receives the request, it will select multiple different data sources for target data collection, and at the same time ensure that the data format of the collected data conforms to the corresponding specifications .

[0021] (2) There are monitors to monitor the data collection process of each oracle machine, and the initial state of each oracle machine is marked as voting type; when 13 oracle machines in the oracle network have completed the collection work, the rest are still in the collection st...

Abstract

The invention discloses a high-credibility data acquisition method based on a block chain oracle machine, and belongs to the technical field of block chains. The invention provides the high-credibility data acquisition method based on the block chain oracle machine, which is used for solving the phenomena of resource waste based on a consensus mechanism in the process of seeking data consistency in the existing block chain technology and incapability of ensuring complete reliability when a single oracle machine is used for acquiring external data and the like. The speed of consensus reaching and broadcasting of the in-chain data in the data acquisition process and the high credibility of the data source are improved. The block chain oracle machine comprises a data collector and a data analyzer; in the data acquisition process, the oracle machine network is used for data acquisition, and when more than half of the oracle machines give the same processing result, the processing result is sent to the block chain.

Description

technical field [0001] The invention relates to a highly credible data acquisition method based on a block chain oracle, belonging to the technical field of block chains. Background technique [0002] In the past, the blockchain technology could not actively obtain external data, which led to the closed nature of the blockchain. Only through the corresponding consensus mechanism can the data on the chain be kept consistent in the end. However, the existence of the consensus mechanism will gradually reduce the consensus efficiency with the increase of participating consensus nodes; The interaction of data becomes possible; the setting of multiple oracle machines, that is, the oracle machine network, can greatly improve the credibility of data; the present invention introduces an oracle machine mechanism into the blockchain to obtain highly credible data. SUMMARY OF THE INVENTION [0003] The present invention provides a highly credible data acquisition method based on a bl...
