Latest Patents

Blockchain-Based Anonymous Trusted Voting Method, Apparatus and Related Device. This invention describes a method for conducting trusted anonymous voting using 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 related commitment tuple, to the blockchain. The commitment tuple supports decryption of the vote tuple.

Timestamp Generation Method and Apparatus, and Electronic Device and Storage Medium. This invention addresses the risk of information leakage when a trusted third party records timestamps. 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 returns the signature result, which is then stored on a blockchain as the file’s timestamp.
