What is Primecoin?
The coin brings together the proof-of-work consensus protocol based on prime numbers.
This is the first crypto in the world to be designed using scientific computing and it has shown that PoW actually exists and works efficiently. Primecoin remains a cryptocurrency and rather than hashing numbers, all it does is to validate transaction by matching them with specific prime numbers. These prime numbers known as Cunningham chains and Bit-Twin chains are unique because difficulty has been shown to increase linearly according to Fermat Test.
The proof-of-work in Primecoin provides security and minting and with a special form of prime number, the network is energy-multiuse. Compared to Bitcoin or other cryptocurrencies, Primecoin processes payment transactions faster. It is designed to permit high level of security and a prosperous mining market.
