Hal Finney's re-usable proof of work (RPOW) system preceded Bitcoin by many years and IMHO satisfied the technical requirements of being a viable digital currency, but failed on one of the "social" requirements: namely, RPOW needed -- but never got -- a way to persuade millions of ordinary people to take it seriously.
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.
> Currently I'm working on something Mike Hearn suggested, using the security features of modern processors, designed to support "Trusted Computing", to harden Bitcoin wallets. It's almost ready to release. I just have to do the documentation.
Yes, that's it, but I'm more concerned with what happened to what was basically an eloquent tribute to Hal that was upvoted by 200 people, and included comments by several people who knew Hal.
Oh, one thread degenerated into a ridiculous cryogenics debate. That's sad, I wish people on both sides of that debate had chosen to show Hal the same respect that other software pioneers were given when they passed away and were featured on HN.
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).
We buried it because it turned into a flamewar about cryogenics instead of being about Hal Finney, and there was another post about Hal (this one) on the front page at the time.
Despite the idiosyncrasies of the community, at least bitcointalk members were there sharing and praising his work until the last days... It is not sad nor strange, it is actually a nice thing...
The fact that he was actually quite emotional and thankful for these posts is the only thing that matters here.

Nice try, Mr Hal Finney, esteemed hacker.
