How it works
YACoin is the original creator of Scrypt-N Proof of Work. YACoin chose a PoW algoritm SHA-3 KECCAK to further distance itself from other coin creation schemes. YACoin uses Proof of Stake to secure itself from pure PoW attacks.

Proof of Stake is an improved version from Peercoin's implementation. YACoin counts PoS blocks with equal weight as PoW blocks.
