Realization Technology of Digital Currency Hubee

The digital currency Hubee is an equivalent tool for all digital assets to provide a safe and convenient mobility and storage serve. Mobility (payment) or storage (settlement) of digital assets is easy to solve separately, even with traditional technologies, but when to solve both simultaneously, new technologies are needed. Therefore, in this paper, the necessary functions of digital currency are analyzed and discussed. The biggest technical difficulty in the design of digital currency is the authentication of the identifier claimed by the subject. As long as the identifier authenticity is solved, the subject and object authentication can be easily solved and a real digital signature can be realized. Until now, Identifier authentication technology is an international challenge. English-speaking countries separated the concept of identifier from the concept of identity only last year, but have yet to solve the problem of proving authenticity. On the basis of the Identifier authentication, a digital currency that is unified with payment and settlement currency and is not afraid of loss is realized. The currency does not need a wallet, and the account book does not need a Treasury, which can run in an unattended cloud bank. Hubee is an account-centered, non-centralized system that implements the information assurance policy of “my security is my decision”. Hubee’s scope can be controlled flexibly, it can be directly applied to a scope of a single commercial bank or a scope of a central bank, and can also be applied to different banks and commercial banks and different central banks in a way of mutual recognition. The appearance of Hubee and other digital money will break the traditional monetary management mode and create a new management mode adapted to the digital economy era.
