Abstract

The invention discloses a computing processing method and device based on a block chain, equipment and a medium, and relates to the technical field of block chains. When the method is executed by trusted computing equipment configured with a trusted computing environment, the specific implementation scheme is as follows: obtaining a computing task sent by a computing task initiator and a blockchain account private key of the initiator; performing calculation processing on the calculation task in a trusted computing environment, and obtaining a calculation result; signing the fingerprint information of the calculation result by adopting the account private key, generating a transaction request, and initiating an uplink operation to a blockchain network; and feeding back the calculation result to the initiator. The problem of computational verifiability of private data is solved.

Description

technical field [0001] This application relates to the field of computer technology, in particular to blockchain technology. Background technique [0002] In the current blockchain technology, smart contracts are introduced, which are intended to implement contracts in the real world through codes in the blockchain network to realize de-intermediary contracts. However, because of the openness of the blockchain to data, many privacy-related data cannot be uploaded to the chain, but stored on the chain by uploading data fingerprints. Therefore, as long as private data is involved as input or output, the existing technology cannot directly perform calculations through the existing smart contract system. However, in the application process of the blockchain, there is a large demand to combine the blockchain with the existing data center to provide data privacy calculations, so this has become a pain point of the blockchain technology. Contents of the invention [0003] The e...
