Problems solved by technology

However, the existing decentralized computing oracle solutions only need to randomly select the computing oracle group, ignoring the matching of oracles with different computing capabilities and smart contract computing tasks of different complexity, resulting in huge computing delays that cannot meet Industrial Internet "Low Latency" Requirements

Abstract

The invention discloses an industrial internet block chain trusted computing architecture and method based on a computing oracle machine. The architecture comprises an industrial internet equipment layer, a block chain layer and an oracle machine layer, the industrial internet device layer comprises various kinds of heterogeneous industrial internet devices, and industrial computing tasks are generated in the process of managing the devices; the block chain layer comprises a smart contract and executes an industrial computing task by taking a smart contract engine as a carrier; and the oracle layer comprises a calculation oracle and an on-chain oracle, and is used for improving the calculation capability of the smart contract. The block chain computing system based on the computing oracle machine is designed, and the large computing requirement in an industrial scene is met; in an incentive mechanism of an under-chain oracle network, a matching algorithm based on node computing power is provided, the node computing power is considered in the matching process of an under-chain computing oracle and a computing task, and the total network delay of the computing oracle is reduced.

Description

technical field [0001] The invention belongs to the technical field of block chains, in particular to an industrial Internet block chain trusted computing architecture and method based on computing oracles. Background technique [0002] The industrial Internet connects and controls different resources in industrial scenarios, and has poor tolerance for delay. It requires real-time and efficient network architecture and industrial application operation mechanism. However, the traditional centralized cloud computing cannot meet this demand due to the network data congestion caused by the unified upload of a large number of nodes. Therefore, in order to meet the needs of "large connections and low latency" in industrial scenarios, the decentralized blockchain architecture has become a reliable choice for industrial Internet networking. [0003] Under the blockchain architecture, the Industrial Internet implements decentralized networking to realize point-to-point connections b...
