Preface

"Running bitcoin," the tweet read. Simple and unassuming, just a few words, posted on January 11, 2009. Behind this short message was Hal Finney, who became the recipient of the first-ever bitcoin transaction in history: just a day later, Satoshi Nakamoto sent him 10 BTC directly. While there is intense debate about Satoshi Nakamoto's identity, one fact is undisputed: without Hal Finney, bitcoin might have remained just a little-known whitepaper rather than the financial revolution we know today.

Although he passed away in 2014 due to amyotrophic lateral sclerosis (ALS), his legacy continues to shape the evolution of cryptocurrency. From his early work on privacy software to his final contributions made through eye-tracking technology after being paralyzed, Finney's life seems to be a blueprint of cyberpunk values embedded in bitcoin's DNA.

From Culver City to Cypherpunk

Harold Thomas Finney II was born on May 4, 1956, in Culver City, California, showing early talent in mathematics and computing. After obtaining an engineering degree from the California Institute of Technology in 1979, he started his career in the video game industry. At Mattel Electronics, Finney developed several notable console games, including Adventure, Armor Ambush, and Space Attack. Finney's career trajectory and the development of digital currency itself are intertwined with the backdrop of the cypherpunk movement that emerged in the late 1980s and early 1990s.

Cypherpunk was a loose collective of privacy advocates, cryptographers, and libertarian tech experts who believed strong cryptography could protect civil liberties from government infringement and reshape society. The foundational text of this movement, Timothy C. May's "The Crypto Anarchist Manifesto," proclaimed that cryptographic technology would fundamentally alter the nature of government surveillance and taxation. Finney found his ideological home among these digital revolutionaries. The cypherpunk mailing list established in 1992 became a significant platform for discussing revolutionary ideas on privacy, anonymity, and digital age freedom.

By the early 1990s, Finney joined PGP Corporation and collaborated with cryptography pioneer Phil Zimmermann to develop Pretty Good Privacy (PGP), encryption software designed to safeguard email communication from surveillance. This was not just technical work but also political activism, as the U.S. government at the time classified strong encryption as munitions, restricting its export similarly to weapons. Finney operated two of the earliest cryptographic remailer systems that allowed 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 concern for privacy naturally led him to an interest in digital currency. For a cypherpunk, this connection is obvious: in an increasingly surveilled world, financial privacy represents one of the final 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 carefully and engaged in extensive communication with 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 address the "double-spending problem" through a unique approach: one-time-usable tokens to prevent the same digital currency from being spent multiple times. The system allowed clients to create RPOW tokens by providing a work proof string of a given difficulty (signed by their private key). The tokens were then registered on the server to that signed key. Users could transfer the tokens by signing a transfer order to another public key, which the server would update accordingly.

To address security concerns, RPOW utilized the IBM 4758 secure coprocessor, making the server more trustworthy than traditional systems. Although RPOW never gained widespread adoption, it represented a crucial step toward Bitcoin, demonstrating Finney's profound understanding of how to create digital scarcity. When a mysterious figure named Satoshi Nakamoto published a whitepaper 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 schemes from "ignorant newcomers" before.

But Hal Finney saw something different.

Bitcoin's First User

"I think I was the first person besides Satoshi running Bitcoin. I mined block 70-something, and I was the recipient of the first Bitcoin transaction when Satoshi sent ten coins to me as a test," Finney later recalled. This January 2009 transaction—where Satoshi sent Finney 10 BTC—has since become legendary in the crypto folklore, marking Bitcoin's shift from theory to a working system.

In response to the Bitcoin whitepaper, Finney wrote:

“Bitcoin seems to be a very promising idea. I also think that a form of money that’s deflationary and can’t be counterfeited and have all the other properties that Bitcoin has might actually have some potential value to it.” Over the next few days, Hal Finney exchanged emails with Satoshi Nakamoto, reporting bugs and suggesting fixes. Unlike many cryptographers, he saw the potential of Bitcoin early on.

His enthusiasm was not blind optimism. In a now-famous post from 2009, he wrote, “Thinking about how to reduce CO2 emissions from a widespread Bitcoin implementation.” This indicated that he was already considering the environmental impact of cryptocurrency mining. Based on his rough calculations, each Bitcoin could be worth $10 million. At the time, Bitcoin was only worth a few cents, making this prediction seem far-fetched. Today, with Bitcoin’s price hovering around $100,000, this forecast appears increasingly prescient.

The Diagnosis of Tragedy and a Lasting Legacy

2009 was both a triumph and a tragedy for Finney. As he explored Bitcoin’s potential, he received devastating news: he had been diagnosed with amyotrophic lateral sclerosis (ALS), the same disease that afflicted Stephen Hawking. ALS causes the degeneration of motor neurons, eventually leading to the loss of independent movement, speech, and eventually, the ability to breathe. Typically, patients survive for two to five years after diagnosis.

Yet, even as his body gradually failed him in the last few years of his life, Finney’s mind remained sharp and his spirit unbroken. He continued to contribute to the development of Bitcoin and even learned to program using eye-tracking software during his paralysis. He estimated that his programming speed was about 50 times slower than before his illness.

Finney even developed software that allowed him to control a motorized wheelchair with eye movements—showing that even in severely constrained physical circumstances, he still possessed the innovative problem-solving ability. On August 28, 2014, Hal Finney passed away at the age of 58 due to complications from ALS. Following his wishes, his body was cryopreserved by the Alcor Life Extension Foundation in Arizona, his final optimistic gesture towards technology overcoming human limitations.

Connection to Satoshi Nakamoto

When discussing Hal Finney, it’s inevitable to touch upon the speculation of whether he could be Satoshi Nakamoto. Finney lived in Temple City, California, and his neighbor was a Japanese-American named Dorian Satoshi Nakamoto. Some theorized that Finney might have borrowed his neighbor’s name as a pseudonym. He had technical skills, philosophical positions, and writing styles consistent with communications from Satoshi Nakamoto. Satoshi Nakamoto disappeared from the public eye in April 2011, roughly around the time Finney’s health deteriorated. Finney consistently denied being Satoshi Nakamoto, and evidence suggests they were different individuals.

In addition, the Bitcoin private keys controlled by Satoshi Nakamoto have remained unused since his disappearance, a scenario that would be unlikely if Finney had access to those keys. Finney's wife, Fran, presented a compelling rebuttal, insisting that her husband was not Satoshi Nakamoto. Given Finney's honesty about his involvement in Bitcoin activities and his deteriorating health, he seemed to have no reason to continue such deception. Whether or not he was Satoshi Nakamoto, Finney's contribution to Bitcoin and cryptocurrency was significant.

Since Finney's passing, his legacy has been preserved in various tribute forms within the cryptocurrency space. His wife, Fran Finney, founded the annual "Bitcoin Run Challenge," aimed at fundraising for Amyotrophic Lateral Sclerosis (ALS) research, inspired by Finney's iconic 2009 tweet. The event invites participants to run, walk, or roll any distance to raise funds for the ALS Association.

The "Bitcoin Run Challenge" has become a significant event in the cryptocurrency community calendar. In 2023, the challenge raised over $50,000 for ALS research, a number surpassed in the 2024 event, showcasing the ongoing respect for Finney. Fran also took over Hal's Twitter account, keeping his memory alive by sharing stories and responding to the cryptocurrency community's continued gratitude.

The U.S. Securities and Exchange Commission approving the first Bitcoin exchange-traded fund (ETF) coincided with the timing of Finney's historic tweet 15 years later, on January 11, 2024.

Our Take

For many in the cryptocurrency space, Finney represents an ideal: a talented technical expert who combines technical prowess with moral principles, remains optimistic despite personal tragedies, and sees technology as a tool for human freedom. While Satoshi Nakamoto remains shrouded in mystery, Finney, as the human face of Bitcoin, reminds 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 cryptocurrency space? While the cryptocurrency industry celebrates wealth creation and technological disruption, Finney's legacy challenges us to consider a more fundamental question: what is all this innovation really for? What began as a movement to protect individual freedom through mathematics has sometimes evolved into a form similar to the financial system it seeks to replace—centralized, extractive, and often opaque.

Finney's approach to technology seems simple: to build tools that expand human freedom. Not as an abstract political concept of freedom but as practical, everyday freedom—communication without surveillance, transactions without permission, ownership of personal digital identities. His life demonstrated the power of personal integrity in technology development. Unlike many who compromise principles for market demands, Finney maintained remarkable consistency between his values and work. From PGP to RPOW and then to Bitcoin, each project represented another step towards the same goal: enhancing individual autonomy through cryptography.

The industry should soul-search: Does the system we are building adhere to Hal Finney's ethos and contribute to advancing the cypherpunk vision? Or have we lost sight of the original revolution while chasing the next price surge?
