    No, not the Prisoner of war one. I mean the one for mining. I heard it mentioned a few times, and I don't understand it.

    PoW- Proof of work
    Proof of work was a concept originally designed to sieve spam emails and prevent DDOS attacks. A Proof of Work is essentially a datum that is very costly to produce in terms of time and resources but can be very simply verified by another party. The proof of work for Bitcoin is referred to as a “nonce,” or number used only once. This has been considered an energy-intensive alternative to proof of stake as the computers, unfortunately, have to be on and running, which also drives the market towards centralization of hashing power… which is what the blockchain aims to defeat!

    A proof-of-work (PoW) system (or protocol, or function) is an economic measure to deter denial of service attacks and other service abuses such as spam on a network by requiring some work from the service requester, usually meaning processing time by a computer.
