Proof of work
A mechanism that requires computational work to qualify a candidate block for acceptance.
In more detail
Bitcoin miners repeatedly hash candidate block headers, looking for a result below the network's target. Finding one demonstrates work, but it isn't permission to ignore the rest of the rules. Nodes still check the block's transactions and other requirements before accepting it into their chain.
How you might use it
A miner finds a header hash that meets the target, then broadcasts the block for nodes to check.
