Li’s listed patents address ways to use blockchain technology to support trusted processes while reducing reliance on centralized intermediaries.

- Blockchain-Based Anonymous Trusted Voting Method, Apparatus and Related Device. This invention describes a voting process that hashes original voting content, blinds a commitment using information from other voters, and signs the resulting commitment tuple. After verification, related vote data and commitment information are uploaded to a blockchain. The commitment information can be used to decrypt the vote tuple, supporting anonymous yet verifiable voting.

- Timestamp Generation Method and Apparatus, and Electronic Device and Storage Medium. This invention aims to reduce the risk of information leakage associated with traditional timestamp systems that rely on a trusted third party. The method hashes a file record and sends the hash to a random issuer, which signs it together with the time it was received. The resulting signature is stored on a blockchain as the file’s timestamp.
