  • Verifiable, decentralized zero-knowledge central bank digital currency
    Patent number: 12719687
    Abstract: A zero-knowledge CBDC (zkCBDC) banking system uses zero-knowledge proofs to prove that commercial banks are processing transactions correctly. Commercial banks are the provers of the zero-knowledge proof system. The banks generate a zero-knowledge proof for one or more transactions processed by the bank. The banks also generate a hash of the total amount of the transaction(s). The zero-knowledge proof and associated transaction hash are submitted to a blockchain. The blockchain stores a bank state commitment value for each commercial bank in the system and includes a smart contract with code for verifying the zero-knowledge proofs. Once a proof is verified, the bank's state commitment value is updated and the transaction hash is added to the verifier's state.
