Preface

“Run Bitcoin,” this tweet read. Simple and straightforward, just a few words, posted on January 11, 2009. Behind this brief message is Hal Finney, who became the recipient of the first Bitcoin transaction in history: just one day later, Satoshi Nakamoto directly sent him 10 BTC.

Although debates about Satoshi Nakamoto’s identity are intense, one fact is indisputable: without Hal Finney, Bitcoin might have remained just an obscure white paper 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 completed through eye-tracking technology after paralysis, Finney’s life seems like a blueprint embedding cyberpunk values into Bitcoin’s DNA.

From Cypherpunks to Crypto Punks

Born on May 4, 1956, in Coalinga, California, Harold Thomas Finney II showed early talent in 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 famous console games, including “Adventure,” “Armor Attack,” and “Space Attack.”

Finney’s career trajectory, as well as the development of digital currencies themselves, cannot be separated from the background of the Cypherpunk movement that emerged in the late 1980s and early 1990s.

Cypherpunks are 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 the movement, Timothy May’s “The Crypto Anarchist Manifesto,” proclaimed that cryptography would fundamentally change the nature of government regulation and taxation.

Finney found his ideological home among these digital revolutionaries. The Cypherpunk mailing list, established in 1992, 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., collaborating with cryptography pioneer Phil Zimmermann to develop “Pretty Good Privacy” (PGP), an encryption software aimed at protecting email communications from surveillance. This was not only a technical endeavor but also a form of political activism, as the U.S. government classified strong encryption technology as munitions, restricting its export and regulating it like weapons.

Finney operated two of the earliest cryptography-based anonymous remailer 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 Experiments

Finney’s focus on privacy naturally led to an interest in digital currencies.

For Cypherpunks, this connection was obvious: in an increasingly surveilled 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 carefully and engaged in extensive correspondence 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 spent multiple times.

The system created RPOW tokens by allowing clients to present a proof-of-work string of a given difficulty (signed with their private key).

These tokens were then registered on a server with the signing key. Users could transfer tokens by signing a transfer order to another public key, and the server would update the registration accordingly.

To address security concerns, RPOW used an IBM 4758 secure cryptoprocessor, making the server more trustworthy than traditional systems. Although RPOW was never widely adopted, it represented a crucial step toward Bitcoin, demonstrating 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” on a cryptography mailing list in October 2008, most readers dismissed it. Cryptographers had seen too many grand plans from “ignorant newcomers” before.

But Hal Finney saw something different.

The First User of Bitcoin

“I believe I was the second person after Satoshi to run Bitcoin,” Finney later recalled. “I mined over 70 blocks and was the recipient of the first Bitcoin transaction, when Satoshi sent me 10 BTC as a test.”

This transaction in January 2009—Satoshi Nakamoto sending Finney 10 BTC—has become legendary in cryptocurrency lore, marking Bitcoin’s transition 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 form of unforgeable tokens, if their production rate is predictable and not subject to corruption, could have potential value.”

In the following days, Finney exchanged emails with Satoshi, reporting bugs and suggesting fixes. Unlike many cryptographers, he recognized Bitcoin’s potential early on.

His enthusiasm was not blind optimism. In a now-famous post from 2009, he wrote:

“Thinking about how to reduce the carbon footprint of widespread Bitcoin adoption.”

This indicates 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 worth only a few cents, making this prediction seem far-fetched. Today, with Bitcoin hovering around $100,000, this prediction appears increasingly prescient.

Tragedy, Diagnosis, and Lasting Legacy

2009 was both a victory and a tragedy for Finney. While exploring Bitcoin’s potential, he received devastating news: he had amyotrophic lateral sclerosis (ALS), the same disease that afflicted Stephen Hawking.

ALS causes the degeneration of motor neurons, ultimately leading to an inability to walk, speak, or breathe independently. Typically, the time from diagnosis to death is two to five years.

Yet, even in his final years of physical decline, Finney’s mind remained sharp, and his spirit unbroken.

He continued to contribute to Bitcoin’s development and learned to program using eye-tracking software during paralysis. He estimated that his coding speed was about 50% slower than before his illness.

Finney even developed software that allowed him to control a mechanical wheelchair through eye movements—demonstrating his ability to solve problems innovatively even under severe physical limitations.

On August 28, 2014, at age 58, Hal Finney died from complications of ALS. In accordance with his wishes, his body was cryonically preserved at the Alcor Life Extension Foundation in Arizona, representing his final optimistic expression that technology could overcome human limitations.

Connection to Satoshi Nakamoto

When discussing Hal Finney, one inevitably considers whether he might have been Satoshi Nakamoto.

Finney lived in Tempe, Arizona, with a neighbor named Dorian Nakamoto, a Japanese-American.

Some speculate that Finney may have borrowed his neighbor’s name as a pseudonym.

He possessed the technical skills, philosophical stance, and writing style consistent with Satoshi’s communications.

Satoshi Nakamoto disappeared from the public eye in April 2011, roughly coinciding with Finney’s health deterioration.

Finney always denied being Satoshi, and evidence also suggests they are different individuals.

Moreover, the Bitcoin private keys controlled by Satoshi have remained unused since his disappearance. If Finney had access to those keys, such a situation would be unlikely.

Finney’s wife, Fran, offered a compelling rebuttal, insisting that her husband was not Satoshi. Given Finney’s openness about his involvement in Bitcoin and his worsening health, he seemed unlikely to continue such deception.

Whether or not he was Satoshi, Finney’s contributions to Bitcoin and cryptocurrency are monumental.

Since Finney’s passing, his legacy has been celebrated in various ways within the crypto community.

His wife, Fran Finney, founded the annual “Bitcoin Running Challenge,” which aims to raise funds for ALS research, inspired by Finney’s iconic tweet from 2009.

Participants run, walk, or roll any distance to raise money for the ALS Association.

The “Bitcoin Running Challenge” has become a significant event on the crypto calendar. In 2023, it raised over $50,000 for ALS research, and the 2024 event surpassed that, reflecting ongoing respect for Finney.

Fran also manages Hal’s Twitter account, sharing stories and responding to the crypto community’s ongoing gratitude, keeping his memory alive.

The U.S. Securities and Exchange Commission’s approval of the first physically-backed Bitcoin ETF coincides precisely with the anniversary of Finney’s historic tweet, on January 11, 2024.

Our Perspective

For many in the cryptocurrency space, Finney represents an ideal: a talented technologist who combined technical expertise with moral principles, remained optimistic despite personal tragedy, and viewed technology as a tool for human freedom.

While Satoshi remains shrouded in mystery, Finney, as the human face of Bitcoin, reminds us that behind the code and cryptography, cryptocurrencies ultimately are about people and their desire for a better world.

Hal Finney’s story compels us to confront uncomfortable questions: what do we truly value in the crypto space?

Despite the industry celebrating wealth creation and technological disruption, Finney’s legacy challenges us to think more fundamentally: what is all this innovation really for?

The movement that initially protected individual freedom through mathematics has sometimes evolved into a form similar to the financial systems it sought to replace—centralized, extractive, and often opaque.

Finney’s approach to technology seems simple: build tools that expand human freedom. Not as abstract political concepts, but as practical, everyday freedoms—communicating without surveillance, transacting without permission, owning one’s digital identity.

His life demonstrates the power of personal integrity in technological development. Unlike many who compromise principles for market needs, Finney maintained remarkable consistency between his values and work. From PGP to RPOW to Bitcoin, each project represented a step toward the same goal: enhancing individual autonomy through cryptography.

The industry should ask itself: do the systems we build align with Hal Finney’s vision and contribute to the Cypherpunk ideals? Or are we lost in pursuit of the next price surge, drifting away from the original revolutionary purpose?
