Seven years ago today, legendary computer programmer and recipient of the first-ever Bitcoin transaction Hal Finney passed away as a result of complications of ALS.
Finney worked as a video game developer and then as a developer for PGP Corporation, an early public-key cryptography software provider. He was also an active member of the cypherpunks mailing list and, in 2004, created the world’s first reusable-proof-of-work (RPOW) system, a variation on the proof-of-work system that would later define Bitcoin.
But Finney is probably best remembered by Bitcoiners for his early insight into how revolutionary the project could be. As our Aaron van Wirdum reported last year, Finney was one of the first members of the cryptography mailing list to recognize its potential.
“Bitcoin seems to be a very promising idea,” he wrote in 2008, responding to an email that Satoshi Nakamoto sent to the list sharing the Bitcoin white paper. “I like the idea of basing security on the assumption that the CPU power of honest participants outweighs that of the attacker… I also do think that there is potential value in a form of unforgeable token whose production rate is predictable and can’t be influenced by corrupted parties.” SOURCE Bitcoin Hal Finney Memorial – Bitcoin Magazine: Bitcoin News, Articles, Charts, and Guides
