The bitcoin world lost one of its earliest pioneers today with the legal passing of Hal Finney, the recipient of the world's first bitcoin transaction and its first identified developer after Satoshi Nakamoto. He was 58 years old.
Finney had been diagnosed with the disease ALS (Amyotrophic lateral sclerosis, or Lou Gehrig's disease) in 2009 and was wheelchair-bound for the last few years of his life. Despite this, he remained as active as possible in the bitcoin community, even giving interviews as recently as March of this year.
Finney was also a key figure in the world of cryptography, having worked as the second developer after Phil Zimmermann on the popular PGP system, and was a regular contributor to the legendary 'cypherpunks' cryptographer mailing list.
A decentralized P2P version of RPOW, also based on Hashcash, lies at bitcoin's heart, which is the first widespread use of the system.
Finney wrote at the time:
Satoshi Nakamoto sent Finney the first-ever bitcoin transaction in January 2009, and Finney continued to assist Nakamoto with the initial bitcoin code as the two interacted on Bitcoin Talk forum.
Shortly after collaborating with Nakamoto on early bitcoin code in 2009, Finney announced he was suffering from ALS. Increasing paralysis, which eventually became near-total, forced him to retire from work in early 2011.
Although Greenberg concluded that Finney was not Satoshi Nakamoto, the story is sprinkled with enough subtle hints to leave the question open.
After arriving at a hospital near Alcor's facility with his wife Fran on Tuesday, Finney was administered "drugs to ensure no consciousness and his ventilator was removed". He was declared legally deceased at 9:00am local time on 28th August.
Finney is now undergoing initial preparation for cryopreservation before being placed into long-term storage, in the hope of being revived at some future point if or when more advanced technology makes it possible.
Finney mined many bitcoins in the early days of the project, but cashed many of them in to pay for his medical bills in 2013 after their value topped $100 each.
Another of the computing world's legendary figures whose work is far better known than his actual name, Finney's efforts in both digital currency and cryptography are bound to have far-reaching effects, with the full extent of their influence still unknown.
In his last-ever post on Bitcoin Talk, titled 'Bitcoin and Me’ and dated March 2013, Finney concludes with the following passage:
The leader in news and information on cryptocurrency, digital assets and the future of money, CoinDesk is a media outlet that strives for the highest journalistic standards and abides by a strict set of editorial policies. CoinDesk is an independent operating subsidiary of Digital Currency Group, which invests in cryptocurrencies and blockchain startups.
