Hal Finney (Computer Scientist)

Harold Thomas Finney II (May 4, 1956 – August 28, 2014) was an American software developer. He was credited as the lead developer on several console games in his early career. Finney later worked for PGP Corporation. He also was an early bitcoin contributor and received the first bitcoin transaction from bitcoin’s creator Satoshi Nakamoto.

Early Life and Education
Finney was born in Coalinga, California, on May 4, 1956, to Virginia and Harold Thomas Finney. His father was a petroleum engineer. His mother’s grandmother was a member of the Daughters of the American Revolution and a Congregationalist. Harold Finney II attended the California Institute of Technology, graduating with a BS in engineering in 1979.

Career
After graduation from Caltech, he went to work in the computer gaming field for a company that developed video games such as Adventures of Tron, Armor Ambush, Astrosmash, and Space Attack. He later went to work for the PGP Corporation, with whom he remained until his retirement in 2011.

Finney was a noted cryptographic activist. During the early 1990s, in addition to being a regular poster on the cypherpunks listserv, Finney ran two anonymous remailers. Further cryptographic activism included running a (successful) contest to break the export-grade encryption Netscape used.

In 2004, Finney created the first reusable proof of work system before Bitcoin. In January 2009, Finney was the Bitcoin network’s first transaction recipient.

Bitcoin
Finney was a cypherpunk and said:

It seemed so obvious to me: “Here we are faced with the problems of loss of privacy, creeping computerization, massive databases, more centralization – and [David] Chaum offers a completely different direction to go in, one which puts power into the hands of individuals rather than governments and corporations. The computer can be used as a tool to liberate and protect people, rather than to control them.”

He was an early Bitcoin user, and on January 12, 2009, he received the first bitcoin transaction from Bitcoin’s creator Satoshi Nakamoto. Finney lived in the same town for ten years that Dorian Satoshi Nakamoto lived in (Temple City, California), adding to speculation that he may have been Bitcoin’s creator. Finney denied that he was Satoshi Nakamoto.

In March 2013, Finney posted on a Bitcoin forum, BitcoinTalk, that he was essentially paralyzed. Nevertheless, he continued to program until his death; his last project was working on “bcflick,” the experimental software which uses Trusted Computing to strengthen Bitcoin wallets.

During the last year of his life, the Finneys received anonymous calls demanding extortion fees and becoming victims of swatting. In addition, extortionists have demanded fees of more bitcoins than Finney had left after using most of them to cover medical expenses in 2013.

Personal Life
In October 2009, Finney announced in an essay on the blog Less Wrong that he had been diagnosed with amyotrophic lateral sclerosis (ALS) in August 2009. Before his illness, Finney had been an active runner. In addition, Finney and his wife raised money for ALS research with the Santa Barbara International Marathon.

Death
Finney died in Phoenix, Arizona, on August 28, 2014, as a result of complications of ALS and is cryopreserved by the Alcor Life Extension Foundation.

Vitalik Buterin

Vitalik Buterin is a Russian-Canadian programmer and writer primarily known as a co-founder of Ethereum and a co-founder of Bitcoin Magazine.

Buterin is a co-founder and inventor of Ethereum, described as a “decentralized mining network and software development platform rolled into one” that facilitates the creation of new cryptocurrencies and programs that share a single blockchain (a cryptographic transaction ledger). Buterin first described Ethereum in a white paper in late 2013. Buterin argued that bitcoin needed a scripting language for application development. But when he failed to gain agreement, he proposed the development of a new platform with a more general scripting language.

About the Ethereum Project, Buterin has said: “I am truly grateful to have the opportunity to work in such an interesting and interdisciplinary area of industry, where I have the chance to interact with cryptographers, mathematicians, and economists prominent in their fields, to help build software and tools that already affect tens of thousands of people around the world, and to work on advanced problems in computer science, economics and philosophy every week.” However, in a 2018 New Yorker article, his father suggests that Buterin is trying to avoid the focus on him as the philosopher king of the blockchain world. “He is trying to focus his time on research,” Dmitry [Buterin’s father] said. “He’s not too excited that the community assigns so much importance to him. He wants the community to be more resilient
