The original Meros miner, which was never optimized nor threaded. It is not maintained and should not be used.

Mineros requires an active Meros node to work. While it is possible to mine blocks without one, it isn't possible to earn Meros without a node. Mining earns Merit, which is used to verify transactions. Only by verifying transactions do Merit Holders earn Meros. Without any verifications, Meros won't mint Meros.

Where 127.0.0.1 is the Meros node's IP and 5133 is the RPC port.
