Hal Finney was a renowned cryptographer, coder, and bitcoin pioneer and received the first bitcoin transaction from Satoshi Nakamoto. He died in 2014 at the age of 58 after a five-year battle with ALS and donors paid to have his body cryopreserved.

"He’s always been optimistic about the future," says Hal Finney's wife to Wired, "Every new advance, he embraced it, every new technology. Hal relished life, and he made the most of everything."

According to the Satoshi Nakamoto Institute, Hal Finney was a software engineer and an early member of the Cypherpunks. He worked for the PGP Corporation, where he developed some of the earliest PGP code. He eventually built the first anonymous remailer, a first proof-of-work digital cash system.

Finney was an advocate of cryptography and digital privacy so much that he was targeted by Bitcoin's mysterious creator, Satoshi Nakamoto, to receive the very first bitcoin transaction. Few people got to interact with the mind of Satoshi like Hal, and he was first to use the new cryptographic technology after Satoshi.

Days until his death, Finney was working on experimental software called bcflick, which uses an advanced trusted computing to strengthen the security of bitcoin wallets. Hal died of Amyotrophic Lateral Sclerosis (ALS) in 2014 and was later cryopreserved by the Alcor Life Extension Foundation.

Hal Finney became Alcor member A-1436 who chose the whole-body option and was pronounced legally deceased on August 28, 2014 at 8:50 am at the age of 58, in Scottsdale, Arizona. That same day, Hal became Alcor’s 128th patient.

Hal paid for his cryopreservation through a combination of life insurance and bitcoins donated by admirers. His wife, Fran, also has arrangements for cryopreservation. She is glad to have a chance to see him again sometime in the future when they may return in restored and rejuvenated bodies.
