The way Bitcoin met that social requirement was to give early adopters a large financial incentive to promote Bitcoin. The hype around Bitcoin, in other words, in addition to setting off many bullshit detectors here on HN, greatly increased awareness of Bitcoin. And maybe that is the thing that will make Bitcoin more than just bullshit.
Since Hal's system provided no particular financial incentive to its early adopters, the RPOW server Hal designed and implemented sat on the internet for many years, waiting for a rising tide of transactions that never came.
Nice try, Mr Hal Finney, esteemed hacker.
Did this ever get released?
“I have written a truly marvellous program to do this, but I have not yet had time to finish the documentation.”
The fact that he was actually quite emotional and thankful for these posts is the only thing that matters here.
Especially considering how much he and other early cypherpunks pioneered privacy-enhancing software that so many of us have benefited from (PGP and Bitcoin, to name two).
