Quantum resistant blockchain with multi-dimensional quantum key distribution

A system for generating a blockchain, comprising:

• first circuitry for receiving a first group of data;
• blockchain processing circuitry for generating the blockchain for a plurality of groups of data, wherein the blockchain processing circuitry generates the blockchain by:
• generating a first nonce for a first block of the blockchain;
• performing a first hash using the first group of data and the first nonce as an input to a hash function to generate a first digital signature for the first block, wherein the hash function uses encryption based on quantum key distribution using N-state qudits, where N is greater than 2;
• establishing the first block of the blockchain using the first group of data, the first nonce and the first digital signature;
• receiving a second group of data;
• generating a second nonce for a second block of the blockchain;
• performing a second hash using the second group of data, the 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 using N-state qudits, where N is greater than 2;
• and
• establishing the second block of the blockchain using the second group of data, the second nonce, the first digital signature and the second digital signature.

A method for generating a blockchain, comprising receiving a first group of data;

• generating a first nonce for a first block of the blockchain;
• performing a first hash using the first group of data, the first nonce and a digital signature from a previously generated block in the blockchain as an input to a hash function to generate a first digital signature for the first block, wherein the hash function uses encryption based on quantum key distribution using N-state qudits with orbital angular momentum, where N is greater than 2;
• establishing the first block of the blockchain using the first group of data, the first nonce and the first digital signature;
• receiving a second group of data;
• generating a second nonce for a second block of the blockchain;
• performing a second hash using the second group of data, the 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 using N-state qudits with orbital angular momentum, where N is greater than 2;
• and
• establishing the second block of the blockchain using the second group of data, the second nonce, the first digital signature and the second digital signature.
