Block chain-based data storage proving method and device, equipment and storage medium

Abstract

The invention relates to a block chain-based data storage proving method and device, equipment and a storage medium. The method comprises the steps of generating a corresponding trivial certification result in response to a certification task for data stored on a block chain; taking the trivial proof result as constraint input data used for generating a circuit constraint result, and identifying first constraint input data of which the constraint result has regularity from the constraint input data; based on a preset constraint result query table, searching a circuit constraint result corresponding to the first constraint input data; performing constraint calculation based on the second constraint input data to generate a corresponding circuit constraint result, wherein the second constraint input data is the constraint input data except the first constraint input data in the constraint input data; and performing zero-knowledge proof processing based on the obtained circuit constraint result to generate a zero-knowledge proof result. The scheme can save system resources and improve efficiency.

Description

technical field [0001] The present application relates to the field of computer technology, more particularly to the field of blockchain technology, and in particular to a method, device, device and storage medium for data storage proof based on blockchain. Background technique [0002] Blockchain technology is one of the most important technologies in today's society. With its high security, it has been widely used in various scenarios. The secure storage of data is one of the most important applications of blockchain. Storage on the blockchain can greatly improve the security of data storage. When storing data on the blockchain, data proof processing is involved to prove that the data is accurately stored on the blockchain. Zero-knowledge proofs are a common way of proof of data storage. [0003] The traditional zero-knowledge proof method requires the use of CPU pairs to perform complex calculations. For example, substituting data into complex algorithms for complex cal...

Problems solved by technology

[0003] The traditional zero-knowledge proof method needs to use the CPU to perform complex calculations. For example, substituting data into complex algorithms for complex calculations not only consumes a lot of system resources, but also causes the overall efficiency of data storage proofs to be relatively low.
