摘要： The present disclosure provides a digital currency transaction method and system, and related transaction terminals, and relates to the field of computer technology. A specific implementation of the method includes: exchanging, by a first transaction terminal, user certificates with a second transaction terminal to verify user identities of the two parties after establishing a communication connection with the second transaction terminal, negotiating with the second transaction terminal to generate a transaction factor after confirming that the user identity verification of the two parties succeeds, and uploading first digital currency transaction information including the transaction factor to a first operating institution back-end system, and sending, by the first operating institution back-end system, the first digital currency transaction information to a second operating institution back-end system to complete the digital currency transaction. This implementation achieves separation between identity verification and the transaction, reduces user interaction steps, simplifies the transaction process, is not limited by the transaction distance, supports both password-free and password-verified payments, and eliminates the need for a second touch during password verification, thereby greatly shortening the touch time, and enhancing the transaction security.

摘要： The disclosure relates to the technical field of computers. Disclosed are a digital currency management method, apparatus and system. A specific implementation of the method includes: sending one or more first digital currencies to a first currency management apparatus corresponding to a first client, where the one or more first digital currencies belong to one or more second currency management apparatuses different from the first currency management apparatus; and receiving a second digital currency, which is generated by the first currency management apparatus according to the one or more first digital currencies, where the denomination of the second digital currency is equal to the sum of denominations of the one or more first digital currencies. According to the implementation, rapid digital currency exchange may be realized on the basis of the fact that a client receives digital currencies respectively belonging to different digital currency management mechanisms, such that the liquidity of the digital currencies is improved.
