With the development of information technology, big data has had a positive impact on the development of various industries. However, the continued growth of data has led to difficulties in data sharing. Blockchain, with its information sharing characteristics and decentralized management principles, is expected to become the new engine for building a future data sharing platform. Blockchain-based data sharing is useful for recording user transactions and sharing of multi-platform data. However, this technology not only has challenges in information storage, but also risks in third-party transactions. In this article, we propose a big data sharing and transaction framework based on blockchain. This framework uses the blockchain decentralization and openness idea to establish a big data transaction platform for multiple users. For the problem of distributed secure storage of big data in the blockchain, we propose a data-tamperproof mechanism that introduces a cryptographic algorithm to prevent transaction data from being tampered with during user storage. The purpose of this article is to ensure transaction security and data reliability when trading in the blockchain.
