Users can fully control the uplink data in their own hands through private keys, and no one else can privately check it. This enables secure storage, calculation, and transmission of user data.MDC, as the public chain base currency of MagicData Chain, can be used as fuel for the operation of the public chain, as well as to obtain resources and mining rights through collateral. Currently, it can also be used on several DAPPs.MDC is not only a currency, but also a consensus. The Chinese name is magic number coin, and "" number "is Big data: based on blockchain public chain technology, it integrates distributed edge computing, smart contracts, de duplication encryption storage and other technologies, loads well-designed financial mathematical models, and combines software and hardware to provide users with the most secure and reliable data storage, use, financing and other services....
