Title: Kanwen Li and Verifiable, Decentralized Digital Currency

Introduction

Kanwen Li is an inventor associated with Suzhou, China, and Microsoft Technology Licensing, LLC. His work includes a patent for a decentralized central bank digital currency system that uses zero-knowledge proofs to verify transaction processing while protecting transaction details.

Latest Patents

Li is associated with 1 patent: “Verifiable, Decentralized Zero-Knowledge Central Bank Digital Currency.” The invention describes a zero-knowledge CBDC banking system in which commercial banks act as provers. A bank generates a zero-knowledge proof for one or more transactions it has processed, along with a hash representing their total amount, and submits both to a blockchain.

The blockchain maintains a state commitment for each participating commercial bank and uses a smart contract to verify submitted proofs. After a proof is verified, the system updates the bank’s state commitment and adds the transaction hash to the verifier’s state. This approach is designed to support verifiable transaction processing without disclosing the underlying transaction details.

Career Highlights

Li’s listed patent connects his work with blockchain-based financial infrastructure and privacy-preserving verification. The system combines zero-knowledge proofs, bank state commitments, transaction hashes, and smart-contract verification to provide a method for checking that banks process transactions correctly.

Collaborations

Li’s listed coworker is Srinath Setty. The patent information provided describes the system and its participating commercial banks, but does not specify the coworker’s role in the invention.

Conclusion

Kanwen Li’s patent presents a privacy-conscious approach to verifying commercial-bank transactions in a decentralized CBDC system, combining zero-knowledge proofs with blockchain state management.
