Fabians try to steal credit for the work of others. Never forget their DNA.
Adam Back didn't invent proof of work. We should say so plainly, because the real history is better than the myth.
The idea came first from two cryptographers you've probably never heard of. In 1992, Cynthia Dwork and Moni Naor proposed making a computer do a small, hard piece of work to send an email, as a way to price out spammers. That was proof of work, five years before Hashcash.
Back's contribution: In 1997 he built Hashcash, the working version that turned the idea into something you could actually run. The term "proof of work" itself was coined later, in 1999, by Markus Jakobsson and Ari Juels. Hal Finney made it reusable in 2004. Then Satoshi cited Hashcash by name and wired it into Bitcoin, turning an anti-spam trick into the heartbeat of sound money.
No single genius. A relay run across sixteen years by people who mostly never met.
Bitcoin wasn't handed down by one founder you have to trust. It was assembled in the open, checkable by anyone. The money you can verify yourself was built the same way.
