Proof of Work (PoW)
Proof of Work (PoW) is a blockchain protocol in which the creator of the next block is asked to do some work both difficult (processing time consuming) to produce but easy to verify. Producing a proof of work can be a random process with low probability so that a lot of trial and error is required on average before a valid proof of work is generated.
When lauched, one option to earn Steem was by mining. In the Steem official site there was a step by step instruction page: How to mine Steem (retrieved in January 17th, 2017 and not availabe when checked in March 21, 2018). Mining steem was possible since before the first payouts made in July 4th, 2016 and, according to the Hard Fork 0.17 Change Proposal announced in January, 10th, 2017, being ceased with the removal of Proof of Work (PoW). An article about Setting up a Miner was created here in Steem.center at that time.
