Quantum cash settlement system and method based on block chain

Abstract

The invention discloses a quantum cash settlement system and method based on a block chain. The system comprises a quantum cash settlement system, a quantum cash key management system, a quantum cash bank and a quantum cash settlement block chain. The invention discloses a quantum cash settlement method based on a block chain. The quantum cash settlement method comprises a quantum cash extraction process, a quantum cash payment process and a quantum cash deposit process. A user can register in a quantum cash settlement system, and after the identity and legality are verified, a quantum cash bank account can be created; a user completes quantum signature through the quantum cash key management system, extraction and payment of quantum cash can be completed from a quantum cash bank account, or the quantum cash is stored in the quantum cash bank account, and all related data and settlement records of the user are stored in a quantum cash settlement block chain. According to the scheme, the reliability of quantum cash settlement is ensured by combining a block chain technology and a quantum encryption technology, and unconditional security is theoretically achieved.

Description

technical field [0001] The invention belongs to the field of computer technology, specifically relates to the field of quantum technology, and specifically relates to a blockchain-based quantum cash settlement technology. Background technique [0002] Cash settlement refers to the direct payment of cash as the medium of commodity settlement, and its transaction and settlement can occur at the same time. In cash settlement, the characteristic of the settlement process is "payment in one hand, delivery in one hand", and the physical movement of commodities and the value movement and ownership transfer of commodities are carried out at the same time. Therefore, the essential feature of cash settlement is the movement mode of the integration of business flow and logistics, which can ensure the opposite movement of commodity circulation and cash circulation. However, cash settlement also has flaws. It cannot be used for transactions that are not carried out at the same time and ...

Problems solved by technology

This will seriously undermine the security of electronic cash

[0006] 2. The current electronic cash settlement cannot guarantee the anonymity of consumers

Therefore, it is difficult for traditional electronic cash to achieve the anonymity and privacy protection of real cash. Users of real cash have no way of knowing which holders or users of the cash they have experienced before.

[0007] 3. The current electronic cash has a weak ability to resolve settlement disputes

In the settlement dispute settlement stage, the third-party organization needs to obtain the private key of the merchant, but the exposure of the private key will have security risks, and whether the credibility of the third-party organization is sufficient will also affect the audit

Even if the third-party organization is credible, when merchants and users complain, the third-party organization can only verify the identities of merchants and users, and cannot collect enough evidence for auditing, and the centralized settlement data is easily tampered

[0008] 4. The current electronic cash needs to be improved in processing information efficiency

However, my country basically does not have a blockchain-based quantum cash settlement method
