Design of zero knowledge proof algorithm for data transaction

Abstract

This paper proposes a zero-knowledge proof data transaction verification algorithm, aiming to solve the problem that buyers cannot verify data in advance in blockchain-based data transactions. The algorithm combines zero-knowledge proof technology with blockchain to verify a portion of the data in advance. Buyers can specify the data segment to be verified without disclosing other information to ensure their interests. By verifying the data in advance, it is beneficial to promote trust between the two parties and achieve transactions. In practical tests, the verification algorithm of this paper is deployed in the blockchain through smart contracts. The seller sends the data segment and proof to the buyer, and the buyer verifies the data locally. Algorithm analysis and experimental results show that the algorithm performs well in security, efficiency, and has certain practicality and promotion value.
