YACoin is on the list, but I need info.

What is the total supply? That is blank in first post.

What exactly is the PoW algo? One part says Scrypt-N SHA-3, another says just Scrypt-N and in the next sentence talks about SHA-3 Keccak. Finally the miner uses Scrypt-chacha. I know the SHA-3 winner is Keccak but how does it fit into YACoin?
