Latest Patents

Blockchain-Based Anonymous Trusted Voting Method, Apparatus and Related Device. This invention describes a voting process designed to support anonymity and verification through blockchain technology. It hashes the original voting content to produce a commitment value, blinds that value using information from other voters, and signs the resulting commitment tuple with an ESDSA signature. After other voters verify the signature, the method forms a vote tuple and uploads it, along with a commitment tuple used for decryption, to the blockchain.

Timestamp Generation Method and Apparatus, and Electronic Device and Storage Medium. This invention addresses the risk of information leakage when a trusted third party acts as a timestamp authority. The method hashes a file record and sends the hash to a random issuer. The issuer signs the hash together with its receiving time, and the resulting signature is stored on a blockchain as the file’s timestamp.
