Abstract

The invention provides a block chain-based time service oracle machine implementation method. The invention belongs to the technical field of a super account book Fabric block chain, an oracle mechanism and a statistical algorithm. The block chain-based time service oracle machine implementation method designs and realizes a decentralized trusted time service system in a block chain network by utilizing an oracle principle for calling or subscribing an intelligent contract with a time service requirement, takes a block chain network supporting an intelligent contract as an operation environment, and provides a time service for the block chain network, and the block chain network can be easily expanded to a public chain execution environment after an incentive mechanism is added.

Description

technical field [0001] The present invention relates to a Hyperledger Fabric block chain, an oracle (Oracle) mechanism, and a statistical algorithm technology, and in particular to a method for realizing a time service oracle based on a block chain. Background technique [0002] A distributed ledger built using blockchain technology cannot actively obtain information from the outside world, such as calling external services, but relies on a mechanism called an oracle (Oracle). An oracle is a smart contract that allows the outside world to write certain objective facts into the blockchain for use by other smart contracts, such as foreign exchange rates, stock quotes, flight information, weather forecasts, sports results, etc. [0003] The implementation style of the oracle machine is through trusted data sources and through voting. Trusted data sources are often centralized, and multiple data sources can be introduced to reduce the risk of fraud. The voting method generally...
