Len Sassaman: The Cryptographer Likely Suspected to Be Satoshi
Leonard Harris Sassaman was a renowned American technologist and an aggressive advocate of information privacy. He was actively involved in the development and maintenance of the Mixmaster anonymous remailer code, running the remailer known as the rand seed, which plays a very substantial role in the field of digital anonymity.
Len Sassaman was an important figure in the Cypherpunk movement to support privacy with cryptographic technologies. His experience with cryptography and protocol development helped crystallize many of the privacy-enhancing tools that people use today. Throughout his career, he remained steadfastly committed to open-source principles, championing transparent and accessible technology solutions that place users first.
Satoshi Nakamoto is the pseudonym applied to whoever wrote Bitcoin and its first whitepaper, or at least the pseudonymous name given to that person or persons. Coming onto the cryptocurrency scene in 2007, this character was active in the development of the first version of Bitcoin’s software.
Nakamoto communicates with the early Bitcoin community mostly through emails. One could barely find any personal information or background about him. Thus, it is impossible to identify any meaningful true identity behind the name due to the lack of identifiable information.
By 2010, the mysterious figure had already begun to taper off involvement with the Bitcoin project. In the last recorded communication, Nakamoto would write via email to another developer that he was “moved on to other things,” in effect ceding separation from cryptocurrency development.
A great deal of speculation has surrounded who Satoshi Nakamoto really was over the years. The increased popularity and value of cryptocurrencies stir even greater interest in Bitcoin’s origin and who its originator really was. This mystery constitutes one of the most interesting facts that pertain to the world of cryptocurrencies.

One of Sassaman’s major contributions was his work with the Mixmaster anonymous remailer. The tool, which allowed users to send emails anonymously, was a new innovation in digital privacy at the time. He also maintained the Mixmaster code and ran the rand seed remailer.
Beyond Mixmaster, Sassaman played an integral role in many other important projects. Notably, among those, he was working on Pretty Good Privacy software, one of the most popular pieces of software for encrypting emails to this date. His work on PGP and related privacy-enhancing tools showed his commitment to keeping individuals’ communications secure from surveillance and unwarranted access.
Debates have cropped up over the years about Sassaman’s possible connection to Bitcoin and its mysterious creator, Satoshi Nakamoto.
Discussion of his possible connection to Nakamoto was partially fueled by the fact that Sassaman died in July 2011, a few months after the last known communication by Nakamoto to the Bitcoin community back in April 2011.
Events this close together have been enough for some theorists to speculate that Sassaman may have had something to do with the origins of Bitcoin, although no evidence has emerged to prove this.

Len Sassaman was born in Pennsylvania and attended a private school where he showcased exceptional skills in the art of cryptology since childhood.
When he was in his late teens, he moved back to San Francisco and got involved with the local cypherpunk movement. This socio-political strategy emerged during the third wave in the 1980s and focused on intelligent information systems, particularly computer privacy and general pan-cryptography.
Sassaman was a pupil of David Chaum, the man many call the “godfather of cryptography”. His involvement in the Cypherpunk movement helped him engage in dialogues based on topics like privacy, systems of cryptography, and decentralization, which he distinctly engaged in before the dawn of Bitcoin.
Sassaman’s exposure to the associations of the prominent personalities behind the development of various peer-to-peer networks drew him close to the ideas that would later give rise to Bitcoin.
Len Sassaman was a prominent figure in cryptography, and he was known for his work on strengthening digital security and encryption. His contributions were crucial to the cypherpunk movement for privacy security using cryptographic techniques.
Being an expert in Internet security, a big part of Sassaman’s work involved securing online communications, such as giving email services an added layer of security. His line of work was very much central to the principles of decentralization and privacy that undergird Bitcoin.
Given his lifelong dedication to developing tools that offer the utmost privacy, Sassaman had both the motive and wherewithal to remain pseudonymous if he were Satoshi Nakamoto.
Interest in the mystery identity of Bitcoin’s creator was piqued again in 2021 by a study contributed by Evan Leung Hatch. Both pieces place cryptographer Hal Sassaman in the spotlight, pointing out his experience with cryptography and British English.
Hatch’s research pointed out several words related to British English that Nakamoto used, such as the terms “bloody difficult”, “maths”, and “grey.” Moreover, it embeds a headline from the leading newspaper in the UK, The Times, into the genesis block, which puts Bitcoin close to British culture.
Sassaman’s geographic location during the development of Bitcoin further feeds speculation about his involvement. He then lived in Belgium at the time, which again corresponds with the hypothesis that Nakamoto is European.
A more plausible theory suggests that Sassaman has been an active part of European academic and technological communities. According to analysts, the proof of Satoshi’s European descent includes his usage of British English and his online activities in different time zones. However, experts further say that such subtleties in language or other aspects of behaviour are not necessarily indicative of Sassaman and may as well be more deceptions by Nakamoto himself.

While Len Sassaman shared many of the same ideas and values as Satoshi, there’s simply no concrete evidence to link the two of them to Bitcoin’s invention. There are also sufficient differences between Sassaman and Satoshi on the philosophical, technical, and cultural levels to rule this theory out.
At least for a few obvious reasons, Len Sassaman would hardly be a likely candidate to hold Satoshi Nakamoto’s status. First and foremost comes the salient fact that there was an extraordinary contrast between the public persona of Sassaman and the secretive Satoshi.
The late Sassaman was an outspoken character in crypto circles for very public discussions of conferences and projects under his name. That’s in sharp decision to that made by Satoshi Nakamoto to remain pseudonymous and eventually step away from the spotlight.
Satoshi went to considerable lengths to remain pseudonymous, using pseudonymous email addresses and encrypted communication. He never let the slightest hint of his real-world identity slip. Sassaman speaks freely about his ideas concerning privacy and security and says he doesn’t need a pseudonym.
The mystery of Satoshi Nakamoto’s identity has indeed set in place a number of theories about who might be behind Bitcoin. However, it is important to consider the privacy and contributions of those in the fields of cryptography and privacy, such as Len Sassaman. Sassaman’s work was cutting-edge and should be regarded for what it was without coupling it with speculation that in some way links him with Satoshi.
Speculating on or trying to unmask Satoshi’s identity goes completely against what Bitcoin was created for. Privacy, decentralization, and self-sovereignty are at the heart of cryptocurrency, and respecting Satoshi’s wish for anonymity is key to keeping these values intact.
Len Sassaman was a very plugged-in member of the cryptography community, knowing at least dozens of people deeply involved in developing technologies with privacy in mind. Many of those individuals would later be influential in Bitcoin and other cryptocurrencies. Again, despite the general closeness of that circle, there is no good evidence or testimony from anybody who would have known him indicating that Sassaman was Satoshi Nakamoto.
In fact, Sassaman’s closest friends and family members, including his wife, have gone on record to state that he is not Bitcoin’s creator. Given the relatively small size of the cryptography community at the time, if Sassaman were Satoshi, it would be tough to maintain such a crucial project from one’s loved ones.

In a Medium blog posting, Evan Hatch, founder of Worlds, said Len Sassaman worked with Finney on Pretty Good Privacy – better known as PGP – while at IT service provider Network Associates.
Finney was a central figure in the early days of Bitcoin, and he worked very closely with Nakamoto. He was not only the first person to make a contribution to the code of the Bitcoin protocol; he was the first person to run a node and receive Bitcoin in a transaction. In fact, the voluminous correspondence between them further put Finney in a pivotal position within the Bitcoin ecosystem.
Both Finney and Sassaman were pretty savvy regarding how remailer technology worked. It was, in a way, a predecessor of how Bitcoin works. Once upon a time, Adam Back, CEO of Blockstream, theorized that Nakamoto could have been a remailer developer, lending some credence to the idea that Finney could have had something to do with the development of Bitcoin.
Nick Szabo is a computer scientist and a cryptographer. He’s known for developing Bit Gold, a digital currency that many consider to be a precursor to Bitcoin. He invented timestamped databases and has also done a lot of writing on decentralized currencies, all of which bear close resemblance to a number of principles behind Bitcoin.
Due to these similarities, Szabo is always the one mentioned when making speculations on who might be behind this mask of Bitcoin’s creator Satoshi Nakamoto. Actually, studies in stylistics do match his writings with those of Nakamoto. Szabo has always denied that he was Nakamoto, and most prominently after a New York Times article where a number of cryptographers speculated that he was, in fact, this elusive figure behind Bitcoin.
Despite his denials, Szabo has remained germane to the ongoing speculation due to his contribution to early cryptography and decentralized technologies. Apart from Szabo, Hal Finney, Adam Back, and Paul Le Roux are some other popular rumoured candidates for Nakamoto.

| Nick Szabo, a computer scientist and a legal scholar, is usually considered one of the most prominent contenders for the title of Satoshi Nakamoto. His groundbreaking work on digital currencies dates back to the late 1990s with the development of Bit Gold, an early concept of a decentralized digital currency. Bit Gold introduced key concepts that would later underpin Bitcoin, such as proof-of-work mining and cryptographic security. While Bit Gold never took off, it would have a lasting impact on the development of Bitcoin. | Len Sassaman advocated privacy and researched cryptographic technologies. Sassaman contributed to several encryption tools, including Pretty Good Privacy, or PGP, a piece of software that became instrumental for online security. Sassaman passed away in 2011, on the same timeline as when Nakamoto disappeared from the internet. With this timing, some have suspected that Sassaman could be Nakamoto. | Hal Finney was also a computer scientist and cryptographer and is often very discussed as being Nakamoto. On January 12, 2009, Finney was the first to receive a Bitcoin transaction from Nakamoto, recorded on the blockchain. Both lived in Temple City, California. Finney was heavily involved in the PGP protocol and knew well the issues its creator, Phil Zimmermann, had to go through with the U.S. government. It wouldn’t be very surprising if Finney actually was the inventor of Bitcoin. |
There is no definitive proof that Len Sassaman is Satoshi Nakamoto other than the timing of his death being consistent with Satoshi’s sudden disappearance.
There are several other credible candidates for the identity of Satoshi Nakamoto, including Nick Szabo, Dorian Nakamoto, David Chaum, and Hal Finney, each with their own set of qualifications and circumstantial evidence.
Yes, Len Sassaman did make some public comments about Bitcoin and its potential impact on privacy and digital currencies.
“Well, it’s hard to decouple cryptography from identity in a crypto-based currency, but, yes, my concerns are real-world identity issues. Bitcoin is less anonymous than physical cash. Compare to Digicash, which was ‘more’ anonymous,” Len Sassaman.
Len Sassaman passed away on July 3, 2011, at the age of 31. The cause of his death was reported as complications related to a long-term illness.
The exact number of Bitcoins that Len Sassaman owned is not publicly known.
