      Primecoin is an innovative cryptocurrency, a form of digital
      currency secured by cryptography and issued through a
      decentralized mining market. Derived from Satoshi Nakamoto's
      Bitcoin, Primecoin introduces an unique form of proof-of-work
      based on prime numbers.

      The innovative prime proof-of-work in Primecoin not only
      provides security and minting to the network, but also generates
      a special form of prime number chains of interest to mathematical
      research. Thus primecoin network is energy-multiuse, compared to
      bitcoin.
