VERIFIABLE, DECENTRALIZED ZERO-KNOWLEDGE CENTRAL BANK DIGITAL CURRENCY

Resumen de: US20260222208A1

0000 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.

SYSTEMS AND METHODS FOR IMMUTABLY RECORDING AND VERIFYING CRYPTOGRAPHIC FILE HASHES USING BLOCKCHAIN-BASED NON-FUNGIBLE TOKENS

Resumen de: US20260220630A1

Systems and methods are disclosed for immutably recording cryptographic file hash values on-chain and verifying candidate digital files.

For verification, a candidate digital file is hashed to generate a candidate cryptographic file hash value, which is compared to the stored cryptographic file hash value to output a validity result.
