Block chain oracle machine network and data transmission method

Abstract

The invention discloses a block chain oracle machine network and a data transmission method. The method comprises the steps that an oracle machine network is constructed, an oracle machine secret key is autonomously generated, the secret key is adopted to carry out the signature of collected data, and the oracle machine secret key comprises a wallet address, a public key and a private key; the oracle machines in the network communicate with each other through a consensus algorithm to realize sharing of external data; the block chain platform sends the authentication information to all the oracle machines, each oracle machine decrypts the authentication information, and when any oracle machine decrypts successfully, external data can be sent to the block chain platform. According to the method, the oracle machine network is constructed, and the oracle machine is utilized to autonomously acquire, sign and encrypt the external data without a third-party platform, so that the security of data transmission is improved. And through communication between the block chain platform and the oracle machines, the oracle machine with the fastest response is found to complete data transmission, so that the data transmission time is shortened.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a blockchain oracle network and a data transmission method. Background technique [0002] With the development of technology, blockchain technology is becoming more and more mature, and the matching smart terminals have also been vigorously developed. The blockchain system is to encrypt and hash data and data operation records through cryptographic methods, thereby forming an open, transparent, tamper-proof, and traceable distributed database accounting system. This technology can be used in payment, settlement, It is widely used in fields such as deposit and collection of evidence, value transfer, supply chain finance, user credit investigation, regulatory audit, etc. [0003] Due to the security of the blockchain platform, data will be stored on the blockchain platform. The traditional method is to collect data by equipment, and then transmit the data to a third-pa...
