Trusted Computing Data Transaction Scheme based on Blockchain

A blockchain technology based on encryption algorithm is proposed to address the issue of data theft and leakage in data transactions. Use blockchain to record transaction information and confirm the rights of data assets and sources; Use trusted computing and encryption algorithms to ensure data transmission security; After the data provider and demander complete the trusted calculation, the encrypted data results are returned. This scheme can perform data calculations without exposing the data to the data requester, and ensure transmission security through trusted encryption.
