Quantum currency transaction method based on distributed account book

Abstract

A quantum currency transaction method based on a distributed account book. A quantum currency transaction platform, a quantum currency system, a quantum currency verification instrument and the distributed account book are included. The method mainly comprises the steps of quantum currency generation, quantum currency issuing, quantum currency proxy transaction and quantum currency verification. Quantum currency generation refers to that final quantum currency is generated in a quantum currency system under the action of a quantum fingerprint function and a quantum one-way function; quantum currency issuing comprises issuing a transaction order corresponding to the output quantum state to a quantum currency user in a personal mining and proxy purchasing mode, and completing quantum currency proxy transaction and distributed accounting of the transaction; and quantum currency verification comprises verifying whether the quantum states are the same or not by using a quantum currency verification instrument to determine the authenticity of the quantum currency. According to the method, unconditional security of quantum encryption and a distributed account book are utilized, so that the transaction confirmation time of electronic currency is greatly shortened, and meanwhile, the anonymity and privacy of the transaction are improved.

Description

technical field [0001] The invention relates to the fields of quantum currency, block chain and quantum computing, in particular to a quantum currency transaction method based on a distributed ledger. Background technique [0002] In recent years, the rise of electronic currency has provided a new type of cashless settlement method, which is a digital encrypted currency based on cryptography technology and blockchain technology. Based on the design of cryptography, electronic currency, as a digital encrypted currency, can only be paid or transferred by the real owner, which guarantees the anonymity of electronic currency ownership and circulation transactions to a certain extent. Based on blockchain technology, electronic currency transactions are generated by network nodes, thus realizing a point-to-point decentralized payment system that does not rely on specific issuers and is not subject to manipulation and control by the central bank and other financial institutions.
