Block chain method based on quantum key distribution and quantum key privacy enhancement

The invention discloses a block chain method based on quantum key distribution and quantum key privacy enhancement. Comprising the following steps: generating a quantum key through nodes, and distributing the quantum key to each specified node; obtaining the transaction data encrypted by the quantum key through the user node, and generating a block chain shared account book through a peer-to-peer node consensus mechanism according to the transaction data; and obtaining the quantum key and the block chain shared account book through each node, and decrypting the block chain shared account book according to the quantum key to obtain transaction data. The quantum key is generated and distributed to each specified node through the node, the transaction data is encrypted according to the quantum key, the blockchain shared account book is generated after the transaction data is subjected to consensus through the peer-to-peer node, and the node can decrypt the blockchain shared account book according to the quantum
