The invention discloses a digital money mining system and method based on biometric ID authentication, the system comprising a VR head display module, wherein the VR head display module comprises an iris identification module; the iris identification module is used for registration and login of the system; the uniqueness of iris characteristics determines the uniqueness of identity identification.The bioID includes an iris, fingerprints and faces. People perform voting according to point holdings through the DPos voting mechanism 101 nodes with the most votes are selected and 500 nodes are simultaneously selected as backup nodes, which form miners. PoW calculation force comparison is carried out, and the CPU/GPU is used for mining. The invention can give play to the advantages of PoW andDPoS, make up the corresponding shortcomings, avoid a large amount of waste of calculation force, slow out-block speed and the like; Combined with VR, the method lays a foundation for the popularization of VR and provides a carrier for iris recognition.

The embodiment of the invention discloses a digital money processing method, a device, a computer device and a storage medium. The method comprises the following steps of: obtaining a target currencytype corresponding to a digital currency and account identification information; Extracting an associated account and a standard currency type matched with the associated account from the account identification information; If the target currency type matches the standard currency type, a processing operation of the digital currency is performed. The embodiment of the invention can execute subsequent processing operation under the condition of the same digital currency type, so as to improve the safety of digital currency operation.

The embodiment of the invention discloses a digital currency exchange method and device, equipment and a medium. A trusteeship node receives digital currency uploaded by a user terminal; and selectinga token contract matched with the token type to which the digital currency belongs, and converting the digital currency into tokens according to the token contract. The alliance chain stores tokens corresponding to the user terminals transmitted by the hosting node; and when a transaction request transmitted by the user terminal is received, updating the token corresponding to each user terminalin the transaction request according to a rule matched with the transaction request. The digital currency corresponding to the user terminals is stored on the alliance chain in the form of tokens, andthe purpose that the user terminals execute the digital currency transaction is achieved by updating the tokens corresponding to the user terminals. The alliance chain records tokens of different user terminals, and cross-chain transaction among multiple chains can be realized. And the token exchange is that a transaction process is executed by a program code, so that the transaction reliabilityis ensured, and the decentralization effect is realized.
