US Patent 11621836 Quantum resistant blockchain with multi-dimensional quantum key distribution

A system for generating a blockchain including an input for receiving a plurality of groups of data. Blockchain processing circuitry generates the blockchain for the plurality of groups of data. The blockchain processing circuitry generates the blockchain by performing a first hash using the first group of data and a first nonce as an input to a hash function to generate a first digital signature for a first block, wherein the hash function uses encryption based on quantum key distribution and orbital angular momentum. The blockchain processing circuitry establishes the first block of the blockchain using the first group of data, the first nonce and the first digital signature. The blockchain processing circuitry performs a second hash using the second group of data, a second nonce and the first digital signature as an input to the hash function to generate a second digital signature for the second block, wherein the hash function uses encryption based on the quantum key distribution and the orbital angular momentum. The circuitry establishes the second block of the blockchain using the second group of data, the second nonce, the first digital signature and the second digital signature.
