The mystery of Satoshi Nakamoto—the pseudonymous creator of Bitcoin—remains one of the most enduring enigmas in the history of technology and finance. While countless theories have emerged over the years, few figures stand as close to the heart of the mystery as Hal Finney, the first person to receive a Bitcoin transaction and a pioneering cryptographer in his own right.
Recent revelations from Martti Malmi (also known by his alias Sirius), an early Bitcoin developer and collaborator of Satoshi, have brought fresh insights into the timeline and behavioral patterns that may link Hal Finney directly to the Satoshi identity. By analyzing newly disclosed email records, time-stamped activities, health timelines, and cryptographic behaviors, a compelling narrative begins to take shape—one that reframes how we understand Bitcoin’s origins.
The Timeline That Connects Two Identities
In July 2009, emails between Malmi and Satoshi reveal that Satoshi was occupied with another job. Around this same period, Hal Finney was employed at PGP Corporation, a U.S.-based encryption company. This overlap in professional activity suggests that the individual behind the Satoshi pseudonym had active commitments outside Bitcoin development—consistent with Finney’s known employment.
Shortly after, in August 2009, Finney was diagnosed with amyotrophic lateral sclerosis (ALS), commonly known as Lou Gehrig’s disease or "locked-in syndrome." The emails reflect this shift: Satoshi notes increasing busyness during this time, which aligns with the onset of Finney’s deteriorating health.
Then comes a telling gap: from March to May 2010, Satoshi temporarily disappears from correspondence, citing involvement in other projects. Coincidentally, this coincides with two major life events for Hal Finney:
- PGP Corporation was acquired by Symantec in April 2010.
- Finney began experiencing accelerated physical decline due to ALS.

This convergence is not trivial. The timing suggests that personal and professional upheaval may have forced a pause in Bitcoin development—consistent with someone managing both illness and corporate transition.
A Strategic Reemergence
By November 2010, Finney reengages with Bitcoin. He joins Bitcointalk.org, becomes active in discussions, and proposes technical improvements such as faster signature verification methods. His renewed participation follows shortly after Satoshi’s final public interactions.
On December 5, 2010, Satoshi expresses concern about WikiLeaks adopting Bitcoin, fearing backlash. Days later, on December 11–12, he sends his last known public messages about DDoS attacks on the network. Then silence.
On December 7, 2010, Satoshi emails core contributors asking to be listed on the Bitcoin website—while simultaneously removing his own information. This paradoxical move signals a quiet exit strategy already in motion.
Between 2010 and 2011, numerous large Bitcoin wallets were created and never touched—a pattern consistent with long-term holding behavior. These dormant addresses remain unspent to this day, fueling speculation about their origin.
The Handover: From Satoshi to Successors
February 22, 2011: Satoshi sends his final email to Malmi, including a PGP-signed administrator password. April 26, 2011: His last known private message goes to Gavin Andresen, stating he has “moved on to other things.”
This handover occurs just after Finney resumes active development work on Bitcoin-related cryptography. Notably, in 2012, Finney begins exploring Trusted Platform Module (TPM) applications for Bitcoin security—a continuation of foundational thinking.
In March 2013, he publishes code for “BFlick,” a Bitcoin transaction notifier, and on March 17 announces it publicly. Two days later, he writes a reflective blog post titled “Bitcoin and Me.”
There, he reveals he was diagnosed with ALS in 2009—around the same time Satoshi’s activity waned. He states he was “forced into retirement in early 2011,” precisely when Satoshi stepped away.
But here lies a contradiction: if retired, why was he still coding in 2013? Why submit GitHub commits? Why advocate for new protocols?
Unless “retirement” refers not to employment—but to stepping back from public visibility while continuing covert development under a legacy identity.
Cryptographic Clues and Writing Style
One of the most debated aspects of the Satoshi identity is linguistic style. Early Bitcoin whitepapers use phrases like “we propose,” suggesting collaboration. Emails are sent exclusively within Pacific Standard Time (PST) hours—Finney lived in California.
Yet curiously, some emails use British spellings (“cheque,” “realise”), while others use American forms (“realize”). In one message, Satoshi asks Malmi about European payment methods—despite claiming familiarity with EU systems.
This inconsistency may indicate deliberate obfuscation. As PGP co-creator Phil Zimmermann (Finney’s former boss) once faced legal threats over encryption export controls, Finney would have had strong motivation to mask his identity—especially fearing similar scrutiny if linked to Bitcoin.

Moreover, the P2P Foundation account post in 2014—“I am not Dorian Nakamoto”—was posted without PGP verification and could have been made by anyone with account access. Hal Finney passed away in August 2014, just months after this statement.
The Wallet Evidence
Finney claimed his original Bitcoin wallet resided on an old computer. Given his ALS progression, he likely switched to alternative input devices by late 2009 or early 2010—mirroring a shift in how Satoshi might have operated post-2010.
The first Satoshi wallet made its final outgoing transaction in January 2009—shortly after sending 10 BTC to Finney. Since then, over 1 million BTC attributed to early mining remain untouched.
Could these belong to Finney—or be held in trust for successors?
He stated in 2013 that he moved most of his coins to cold storage for inheritance purposes. This explains low-spending patterns among early wallets.
FAQ: Common Questions About Hal Finney and Satoshi
Q: Did Hal Finney ever claim to be Satoshi Nakamoto?
A: No. He consistently denied being Satoshi. However, denial alone doesn’t rule out involvement—especially if protecting the project’s decentralization narrative was a priority.
Q: How does Finney’s technical background support the theory?
A: As a renowned cryptographer who contributed to PGP 2.0 and worked on proof-of-work systems before Bitcoin, Finney had both the expertise and mindset required to design Bitcoin.
Q: Why would Satoshi disappear?
A: With ALS progressing, public exposure could jeopardize the project. By fading out and letting others lead, the protocol could grow organically—free from cult-of-personality risks.
Q: What about differences in coding style?
A: While some argue Bitcoin’s code doesn’t match Finney’s style, collaborative development and intentional obfuscation can account for variations. Plus, early contributors often adapted to shared standards.
Q: Is there definitive proof?
A: Not yet. But the alignment of timeline, location, health events, cryptographic behavior, and linguistic quirks forms a strong circumstantial case.
Q: Why does this matter today?
A: Understanding Bitcoin’s origins helps us appreciate its philosophy: decentralization, resilience, and anonymity as features—not bugs.
A Legacy Beyond Identity
Hal Finney didn’t just receive the first Bitcoin transaction—he embodied its ethos before most understood it. Whether or not he was Satoshi Nakamoto, his influence is undeniable.
He envisioned a greener Bitcoin, supported forks and layer-two innovations like BitDNS and zerocoins, and believed in extensibility—a vision at odds with rigid "maximalist" interpretations today.

His final words on Satoshi echo deeply: “You can almost picture him hand-crafting his software during those last few free moments of his life.” Perhaps those moments were shared—not lived by one man alone.
In stepping back, whoever Satoshi was gave Bitcoin its soul: a ghost in the machine, guiding but never controlling—a spirit now carried forward by every user who runs a node, signs a transaction, or believes in decentralized trust.
That may be the truest legacy of all.
