Method for performing PGP check on e-mail based on block chain technology

The invention discloses a method for performing PGP check on e-mail based on block chain technology. The safety transmission of secret-related data and the transmitting/receiving authentication of thedata in the e-mail management are realized through a chain-type structure, the tamper resistance, an intelligent contract, a consensus mechanism, asymmetric encryption and data safety storage and like technology based on the block chain technology, and a perfect and precise data protection system is established by using a distributed accounting system. The independent authentication technology isrealized by setting an identity authentication server(Server), an accurate time source and a high-strength and high-standard safety mechanism are adopted to confirm the existence of the system processed data at a certain time and the relative time order of the related operation, thereby providing basic service for the time repudiation resistance in an information system; the data security is improved by utilizing the dist
