Block chain-based data storage certification method, device, device and storage medium

Abstract

The present application relates to a blockchain-based data storage certification method, device, equipment and storage medium. The method includes: generating a corresponding trivial proof result in response to a proof task for data stored on the block chain; using the trivial proof result as constraint input data for generating a circuit constraint result, and inputting data from the constraint Among them, the first constraint input data whose constraint result has regularity is identified; based on the preset constraint result lookup table, the circuit constraint result corresponding to the first constraint input data is searched; the constraint calculation is performed based on the second constraint input data, and the corresponding The circuit constraint result; the second constraint input data is the constraint input data except the first constraint input data in the constraint input data; based on the obtained circuit constraint result, zero-knowledge proof processing is performed to generate a zero-knowledge proof result. This solution can save system resources and improve efficiency.

Description

technical field [0001] The present application relates to the field of computer technology, and more to the field of blockchain technology, in particular to a blockchain-based data storage certification method, device, device and storage medium. 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 very important applications of blockchain. Stored on the blockchain, it can greatly improve the security of data storage. When storing data to the blockchain, data certification processing is involved to prove that the data is accurately stored on the blockchain. Zero-knowledge proof is a common way of data storage proof. [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 o...

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.
