Preface
'Running Bitcoin,' this tweet read. Simple and unadorned, just a few words, posted on January 11, 2009. Behind this short message was Hal Finney, who became the recipient of the first Bitcoin transaction in history: just a day later, Satoshi directly sent him 10 BTC. While debates about Nakamoto's identity rage on, one fact remains indisputable: without Hal Finney, Bitcoin might have remained an obscure white paper rather than the financial revolution we know today.
Although he passed away in 2014 from amyotrophic lateral sclerosis (ALS), his legacy continues to shape the evolution of cryptocurrency. From his early privacy software work to his final contributions made through eye-tracking technology after becoming physically paralyzed, Finney's life seems to be a blueprint of the cyberpunk values embedded in Bitcoin's DNA.
From Coalinga to Cypherpunk
On May 4, 1956, Harold Thomas Finney II was born in Coalinga, California, showing an early aptitude for mathematics and computing. After earning an engineering degree from Caltech in 1979, he began his career in the video game industry. At Mattel Electronics, Finney developed several well-known console games, including 'Adventure,' 'Armored Attack,' and 'Space Attack.' Finney's career trajectory and the development of digital currency itself are inextricably linked to the backdrop of the cypherpunk movement that emerged in the late 1980s and early 1990s.
The cypherpunk movement is a loose collective of privacy advocates, cryptographers, and libertarian technologists who believe that strong cryptography can protect civil liberties from government intrusion and reshape society. The foundational text of this movement, Timothy May's (The Crypto Anarchist Manifesto), asserts that cryptographic technology will fundamentally alter the nature of government regulation and taxation. Finney found his ideological home among these digital revolutionaries. Established in 1992, the cypherpunk mailing list became an important platform for discussing revolutionary ideas about privacy, anonymity, and freedom in the digital age.
By the early 1990s, Finney joined PGP Inc., working with cryptography pioneer Phil Zimmermann to develop 'Pretty Good Privacy' (PGP), an encryption software aimed at protecting email communication from surveillance. This was not just technical work but also political activism, as the U.S. government classified strong encryption technology as military-grade and restricted its export, subjecting it to the same regulations as weapons. Finney operated two of the earliest cryptographically-based anonymous forwarding systems, allowing people to send emails without revealing their identities. This was radical technology in the early 1990s, embodying the cypherpunk motto: 'Cypherpunks write code.'
Digital cash experiment
Finney's focus on privacy naturally led him to an interest in digital currency. For cypherpunks, this connection was obvious: in an increasingly monitored world, financial privacy represents one of the last frontiers of personal freedom. This interest was not unique. Cypherpunks like David Chaum, Adam Back, Wei Dai, and Nick Szabo proposed various digital cash systems in the 1990s. Finney studied their work closely and corresponded extensively with Wei Dai and Szabo.
In 2004, Finney created his own digital currency system called Reusable Proof of Work (RPOW). Based on Adam Back's Hashcash concept, RPOW aimed to solve the 'double-spending problem' through a unique approach: tokens that could only be used once, preventing the same digital currency from being used multiple times. The system created RPOW tokens by allowing clients to provide a proof-of-work string of given difficulty (signed by their private key). The tokens would then be registered on the server to that signed key. Users could transfer tokens by signing transfer orders to another public key, and the server would update the registration accordingly.
To solve security issues, RPOW used the IBM 4758 secure cryptographic co-processor, making servers more trustworthy than traditional systems. Although RPOW never gained wide adoption, it represented a key step towards Bitcoin, showcasing Finney's deep understanding of how to create digital scarcity. When a mysterious figure named Satoshi Nakamoto published a white paper titled (Bitcoin: A Peer-to-Peer Electronic Cash System) to a cryptography mailing list in October 2008, most readers dismissed it. Cryptographers had seen too many grand plans from 'clueless newcomers' before.
But Hal Finney saw something different.
Bitcoin's first user
'I think I was the first person to run Bitcoin, apart from Satoshi,' Finney later recalled. 'I mined the 70th block, and I was the recipient of the first Bitcoin transaction when Satoshi sent me ten Bitcoins as a test.' This transaction in January 2009—Satoshi sending Finney 10 BTC—has become legendary in cryptocurrency lore, marking the transition of Bitcoin from theory to an operational system.
In response to the Bitcoin white paper, Finney wrote:
'Bitcoin seems like a very promising idea. I also think that a non-falsifiable token form, if its production rate is predictable and not subject to corrupt influences, could have potential value.' In the following days, Finney corresponded with Satoshi via email, reporting bugs and suggesting fixes. Unlike many cryptographers, he recognized Bitcoin's potential early on.
His enthusiasm was not blind optimism. In a now well-known post from 2009, he wrote: 'Think about how to reduce the carbon footprint of widespread Bitcoin adoption.' This indicates that he had begun to consider the environmental impact of cryptocurrency mining. According to his rough calculations, each Bitcoin could be worth 10 million dollars. At the time, Bitcoin was worth just a few cents, making this prediction seem outrageous. Today, Bitcoin's price hovers around 100,000 dollars, making this prediction increasingly prescient.
Tragic diagnosis and enduring legacy
2009 was both a victory and a tragedy for Finney. While exploring the potential of Bitcoin, he received the devastating news that he had amyotrophic lateral sclerosis (ALS), the same disease that afflicted Stephen Hawking. ALS leads to the degeneration of motor neurons, ultimately causing patients to lose the ability to walk, speak, or breathe independently. Typically, the time from diagnosis to death ranges from two to five years.
However, even as his body deteriorated in the final years of his life, Finney's mind remained sharp and his spirit indomitable. He continued to contribute to Bitcoin's development and learned to program using eye-tracking software during his paralysis. He estimated that his programming speed was about 50 times slower than before he became ill.
Finney even developed software that enabled him to control a mechanical wheelchair through eye movements—demonstrating that even under severe physical limitations, he retained the ability to innovate and solve problems. On August 28, 2014, 58-year-old Hal Finney passed away from ALS complications. According to his wishes, his body was cryogenically frozen at the Alcor Life Extension Foundation in Arizona, marking his final optimistic expression of technology's potential to overcome human limitations.
Connection to Satoshi Nakamoto
When discussing Hal Finney, speculation about whether he could be Satoshi Nakamoto is inevitably involved. Finney lived in Temple City, California, next to a Japanese-American neighbor named Dorian Nakamoto. Some have speculated that Finney may have borrowed his neighbor's name as a pseudonym. He had the technical skills, philosophical stance, and writing style consistent with those of Nakamoto. Nakamoto disappeared from public view in April 2011, roughly coinciding with the deterioration of Finney's health. Finney always denied being Nakamoto, and evidence suggests they are different people.
Furthermore, the Bitcoin private keys controlled by Satoshi Nakamoto have remained unused since his disappearance, making it unlikely that such a situation would occur if Finney had access to those private keys. Fran Finney has made a compelling rebuttal, consistently asserting that her husband was not Satoshi Nakamoto. Given Finney's candor about his involvement in Bitcoin and his deteriorating health, he seemed to have no reason to continue such a deception. Regardless of whether he was Nakamoto, Finney's contributions to Bitcoin and cryptocurrency are immense in their own right.
Since Finney's passing, his legacy has continued in the cryptocurrency space through various forms of tribute. His wife, Fran Finney, founded an annual 'Bitcoin Run Challenge' to raise funds for ALS research, drawing inspiration from Finney's iconic tweet in 2009. The event invites participants to run, walk, or roll any distance while raising money for the ALS Association.
'The Run Bitcoin Challenge' has become a significant event on the crypto community's calendar. In 2023, the challenge raised over $50,000 for ALS research, with the 2024 event surpassing that figure, highlighting the ongoing respect Finney continues to receive. Fran has also taken over Hal's Twitter account, sharing stories and responding to the crypto community's ongoing gratitude, ensuring his memory lives on.
The date the U.S. Securities and Exchange Commission approved the first Bitcoin spot exchange-traded fund (ETF) coincided perfectly with the date of Finney's historic tweet 15 years later: January 11, 2024.
Our perspective
For many in the cryptocurrency space, Finney represents an ideal: a talented technologist combining technical expertise with ethical principles, remaining optimistic despite personal tragedy, and viewing technology as a tool for human freedom. While Nakamoto remains cloaked in mystery, Finney serves as the human face of Bitcoin, reminding us that behind the code and cryptography, cryptocurrency is ultimately about people and their desire for a better world.
Hal Finney's story forces us to confront some unsettling questions: what do we truly value in the realm of cryptocurrency? While the cryptocurrency industry celebrates wealth creation and technological disruption, Finney's legacy challenges us to think about a more fundamental question: what are all these innovations really for? Originally a movement that protected personal freedom through mathematics has sometimes evolved into a form resembling the financial system it sought to replace—centralized, extractive, and often opaque.
Finney's approach to technology seemed simple: to build tools that expand human freedom. Not freedom as an abstract political concept, but actual, everyday freedoms—communication without surveillance, transactions without permission, and ownership of personal digital identities. His life showcased the power of personal integrity in technological development. Unlike many who compromise their principles for market demands, Finney maintained an astonishing consistency between his values and his work. From PGP to RPOW to Bitcoin, each project represented another step toward the same goal: leveraging cryptography to enhance individual autonomy.
The industry should ask itself: do the systems we build align with Hal Finney's vision and help advance the cypherpunk agenda? Or have we lost sight of the original revolutionary direction in the chase for the next price spike?
