Nick Szabo, The Real Satoshi Nakamoto: The Definitive Case Study

The birth of Bitcoin

During the 2008 financial crisis, a visionary computer scientist driven by an ambition to challenge central banks, invented Bitcoin, the world's first peer-to-peer digital cash system utilizing asymmetric cryptography. Bitcoin's enigmatic creator shrouded himself in the pseudonym "Satoshi Nakamoto" to maintain anonymity. Embracing a profound commitment to the principles of decentralization, Satoshi left the project in 2011.

My research on Satoshi's identity points overwhelmingly to renowned computer scientist Nick Szabo, the inventor of smart contracts and Bitcoin's precursor, Bit gold. I present to you the definitive case study of Satoshi Nakamoto.

Who is Nick Szabo?

One of the most influential computer scientists of all time, Nick Szabo is an American polymath with expertise in economics, libertarianism, cryptography, programming, law, and science. Szabo's friend, Donald McIntyre, describes Szabo as a "quiet master of cryptocurrency" and says that his works are:

"comparable to Einstein, Heisenberg, Bohr, Born, and Schrödinger."

In 1989, Szabo earned a bachelor's degree in computer science at the University of Washington, then later returned to California (his birthplace), becoming more involved in extropianism (futurology). Along with fellow extropians Wei Dai and Hal Finney, he joined the cypherpunk movement in the early 1990s due to the overlapping libertarian ideas with extropianism.

Cypherpunks are computer programmers who put the power of privacy and secure communication back into the hands of the public through open source software. A leading voice in the movement, Szabo played a crucial role in hosting real life cypherpunk gatherings alongside Hal Finney, whose early involvement helped shape Bitcoin's future direction.

Notably, Szabo worked at a jet propulsion laboratory, demonstrating his strong math skills. In 2006, Szabo graduated from George Washington Law School with a Juris Doctor. For his many contributions to various academic disciplines, Szabo was awarded an honorary doctorate in the social sciences along with a professorship from Francisco Marroquín University in 2017.

The most ambitious cypherpunk

Szabo has stated on many occasions that he was inspired by David Chaum, the widely recognized inventor of digital cash, and Tim May, a cypherpunk, who in 1988, wrote the "Crypto Anarchist Manifesto," outlining the movement's goals.

In 1995, Szabo began working as a consultant for Digicash, the first digital cash attempt started by none other than David Chaum.

Szabo's groundbreaking 2001 paper, "Trusted Third Parties are Security Holes," laid out the foundational arguments behind distributed networks functioning without trusted intermediaries. This influential work continues to shape the thinking of Bitcoin advocates across the world.

Out of all Satoshi candidates, Nick Szabo and Hal Finney were the only cypherpunks motivated enough to continue working on serious digital cash designs in the 2000s after Digicash's bankruptcy. Namely, they were Bit gold and its variant (more on this later).

Bit gold is the predecessor of Bitcoin

Nick Szabo invented Bit gold in 1998, a sketch for a decentralized cryptocurrency using "bit gold miners" to solve "complex mathematical puzzles." Bit gold happens to use Bitcoin's proof-of-work algorithm: Adam Back's Hashcash.

Importantly, Szabo refers to Bit gold as Bitcoin's "predecessor design."

The project was first released on a private email list that Szabo started, known as "Libtech." Compellingly, the recipients were Hal Finney, Wei Dai, Tim May, as well as economists George Selgin and Larry White.

Many don't know that Wei Dai released his B-Money proposal on this list, and went to the same university as Szabo.

Szabo has an impressive blog known as Unenumerated, where he displays his expertise. He decided to publish Bit gold in 2005 after Hal Finney encouraged him to.

In a 2005 blog post, "Antiques, Time, Gold and Bit gold," Szabo quintessentially stated:

"There are some problems involved with implementing unforgeable costliness on a computer. If such problems can be overcome, we can achieve bit gold. This would be the first online currency based on highly distributed trust and unforgeable costliness rather than trust in a single entity and traditional accounting controls. Hal Finney has implemented a variant of bit gold based on a tamper-evident computer plug-in card, for which remote users can verify what code is running on the card."

This passage shows that Szabo, as early as 2005, believed his Bit gold design was likely going to be the first secure, P2P online currency. It also demonstrates that Hal Finney's RPOW was one of Szabo's key inspirations.

Further showing his motivation, Szabo stated in a largely unknown Bit gold draft:

"Bit gold, even more so than precious metals, will become a hedge and safe haven for preserving value in the face of credit and political exposures."

Additionally, in Szabo's 2011 blog post titled, "Bitcoin What Took Ye So Long," he equates the early ideas of Bitcoin to Bit gold:

"The short answer about why [Bitcoin] took so long is that the bit gold/Bitcoin ideas were nowhere remotely close to being as obvious [as] gwern suggests."

For context, Gwern is another Satoshi researcher. The timing of Szabo's blog post is compelling. May 2011 was reportedly the same month Satoshi sent has last emails to core developers; according to Nathaniel Popper, a former New York Times journalist, who described this in an extensive 2015 article about Szabo being the likeliest Satoshi candidate:

"Mr. Szabo first made brief mention of Bitcoin on his blog in mid-2009, and in 2011, when the currency was still struggling to gain traction, he wrote about it again at greater length, noting the similarity between bit gold and Bitcoin.... May 2011 was also the last time Satoshi communicated privately with other Bitcoin contributors. In an email that month to Martti Malmi, one of the earliest participants, Satoshi wrote, “I’ve moved on to other things and probably won’t be around in the future.”

Szabo asked for Bit gold contributors 6 months before the whitepaper

In the months leading up to Bitcoin's public release, Szabo penned a blog post titled "Bit gold Markets" where he clarified aspects of the design and possible improvements. The date and URL are mismatching because Szabo later backdated the blog post for it to appear after the publication of the Bitcoin whitepaper (listed as December 27th on the new version).

Interestingly, he wrote in the comments:

"I suspect this is all obscure enough that (a) it may require most people to sit down and work it out for themselves carefully before it can be well understood, and (b) it would greatly benefit from a demonstration, an experimental market (with e.g. a trusted third party substituted for the complex security that would be needed for a real system). Anybody want to help me code one up?"

6 months later, the Bitcoin whitepaper was released. Ultimately, it appears Szabo didn't receive any contributors as a result of this blog post.

The above revelation is outweighed by a far more significant comment that Szabo made in the same comment section (discussed next), which casts significant doubt as to whether Bit gold was truly the design Szabo was pushing.

Bit gold is the early draft of Bitcoin

It is highly unlikely Satoshi (or any other inventor) wouldn't have an early draft. The early draft of Bitcoin appears to be Bit gold based on Szabo's unique timing, as well as the highly similar names/vocabulary, distributed database, and timestamped PoW hash chain. And, of course, Szabo asserts it is Bitcoin's predecessor.

Moreover, there is evidence that Szabo was the most motivated cypherpunk to continue working on a digital cash design through the 2000s. Importantly, Bit gold underwent significant improvements, which Szabo summarized in the same month Satoshi sent his last emails.

Bit gold had a problem: the PoW solutions were the actual currency, and not used for securing the protocol, meaning it lacked Sybil resistance. This happens to be one of the most crucial advancements in the Bitcoin design (which Szabo explains in 2011).

The other key difference is Bit gold aimed for high levels of privacy, whereas Bitcoin prioritizes other factors over privacy. However, it is clear that Szabo continuously researched ways to improve Bit gold over time.

Daniel Nagy is a cryptographer who frequently commented on Szabo's blog, and he published a digital cash design in 2007 featuring reduced privacy features, but high security and ease of use.

In an August 2007 blog post, Szabo appeared to realize that Nagy's privacy model would likely be the most successful, as opposed to the initial sketch of Bit gold featuring high levels of privacy. Szabo's description is noticeably similar to Bitcoin's privacy model:

"Thus, the main advantage of Nagy's scheme, which may or may not make up for its reduced privacy features, comes from the ability to use it without having to install any extra software at all -- to just, for example, cut and paste the cash from an e-mail where you received it from one person to an e-mail where you pay it to another. Your word processor can be your wallet. If this is an important use-case, then Nagian cash may succeed where Chaumian cash failed."

Curiously, a Bitcoin user asked Satoshi in 2010 when Bitcoin's production began. Satoshi admitted in his response that he started working on the project in 2007. Based on Satoshi's dialogue, it seemed like he wanted to improve upon an existing design by removing trust-based components:

"Since 2007.  At some point I became convinced there was a way to do this without any trust required at all and couldn't resist to keep thinking about it.  Much more of the work was designing than coding. Fortunately, so far all the issues raised have been things I previously considered and planned for."

6 months before the whitepaper, Szabo indicated the same notion expressed by Satoshi regarding trust when discussing possible Bit gold improvements:

Byrne (blog commenter): "Why do the puzzling at all, rather than issuing a fixed amount of currency inflated at a predictable rate, with unique identifiers for each unit of currency?"

Szabo: "This is an interesting idea, something like the idea that the Fed should follow a simple algorithm rather than trying to outguess markets. But the real question for beating bit gold is how do we do this without having to put full trust in third parties? If we can figure that out, we've come up with something better than bit gold. ("We" as usual on this blog being just whoever wants to explore the possibility, not "the government" :-)"

Crucially, Szabo suggested that someone should implement a better version of Bit gold, inflated at a predictable rate. Bitcoin's inflation rate happens to be algorithmically predictable, which is remarkably similar to Bitcoin in description.

Impressively, Szabo invented an early version of the blockchain in 1998 (which didn't quite have blocks). In Bit gold, the title registry was Szabo's design for a decentralized database with shared ownership records using public key cryptography, based on a chain of signed transactions (solved puzzles). It is the same database described in Szabo's exemplary paper, "Secure Property Titles Without Ownership Authority."

Szabo further described Bit gold's database in a comment on his "Bit gold Markets" blog post 6 months before the Bitcoin whitepaper; stressing its open source nature, like Satoshi did with Bitcoin:

"The entire value chain from puzzle to solution, and all transfers of title, are available for all bit gold and can be audited by anybody at any time."

"Value chain" is noticeably similar to terms Satoshi used, including "time chain" and "block chain." Other Satoshi-like terms such as "chain of puzzles and solutions" and "miners" also appear in this blog post.

As a matter of fact, Szabo wrote in the same month Satoshi sent his last emails about how his secure property titles design was crucial for the invention of Bitcoin:

"Only a few people had read of the bit gold ideas, which although I came up with them in 1998 (at the same time and on the same private mailing list where Dai was coming up with b-money -- it's a long story) were mostly not described in public until 2005, although various pieces of it I described earlier, for example the crucial Byzantine-replicated chain-of-signed-transactions part of it which I generalized into what I call secure property titles."

In a 2018 Bitcoin Magazine piece titled, "The Genesis Files: With Bit Gold, Szabo Was Inches Away From Inventing Bitcoin," writer Aaron van Wirdum astutely summarized Bit gold:

"Indeed, it's not difficult to see Bit Gold as an early draft of Bitcoin. Apart from the shared database of ownership records based on public-key cryptography, the chain of proof-of-work hashes has an eerie resemblance to Bitcoin's blockchain. And, of course, the names Bit Gold and Bitcoin are not too far apart either."

Satoshi oddly didn't cite Bit gold in the whitepaper

The Bitcoin whitepaper is a magnificent work of computer science. Whoever wrote the paper was likely familiar with the cypherpunk movement and Bit gold. After all, Bit gold describes miners solving complex proof-of-work puzzles that are timestamped in a decentralized database. Thus, this makes Bit gold closer to the design of Bitcoin than B-Money.

Since Nick Szabo is a well-known cypherpunk and wrote Bit gold, it seems odd that Satoshi would not cite Bit gold in the whitepaper; unless Szabo was the primary author. This is further supported by Satoshi being careful enough to give proper credit to Adam Back for Hashcash and Wei Dai for B-money; even emailing them to ask if the citations were correct.

Satoshi seemingly tried to give credit to everyone but himself.

Satoshi tried to avoid Bit gold's discussion

We already know Bitcoin's name is noticeably close to Bit gold, but it wasn't cited it in the whitepaper. As it turns out, Satoshi's behavior concerning Bit gold was a trend. He wanted to avoid discussion of the project until no longer possible.

When Hal Finney received the first Bitcoin transaction from Satoshi, it was clear that he took an immediate interest far beyond any other contributor. This is likely because the software had striking similarities to his friend's idea.

In a discussion with Satoshi about the network structure, one week after the whitepaper, Finney stated:

"Nick Szabo wrote many years ago about what he called bit gold and this could be an implementation of that concept."

In Satoshi's response to Finney, he ignored the part about Bit gold. Satoshi clearly had the opportunity to give proper credit to Nick Szabo through an email, but strangely chose not to. In 2010, however, Satoshi backtracked immensely and admitted that Bitcoin was an implementation of B-Money and Bit gold:

Strikingly, the content of both messages is identical. Hal Finney called Bitcoin an "implementation" of Bit gold, which is the same term Satoshi used in 2010. In addition, Hal Finney linked to Szabo's Bit gold sketch in 2008, so Satoshi must have seen it. Crucially, in 2010, Satoshi linked to Bit gold as well.

It is clear by that point, Satoshi felt he could no longer leave out mention of Bit gold's influence. As it turns out, the 2010 message appears to have been a major blunder by Satoshi. This is because Satoshi said Bitcoin was an implementation of Bit gold (and it wasn't cited in the whitepaper), supporting the notion he was aware of Bit gold long before the project.

Had Satoshi never mentioned Bit gold and formed this noticeable discrepancy, far less suspicion would have been placed on himself.

Uniquely identical personalities and skills

Satoshi was highly motivated to insure scarcity and a lack of central bank involvement in Bitcoin. For example, he embedded a British newspaper headline into the Genesis block stating, "Chancellor on Brink of Second Bailout for Banks."

Like Satoshi, Szabo strongly desired to stifle inflation and remove the need for central banks in Bit gold:

"The problem, in a nutshell, is that our money currently depends on trust in a third party for its value. As many inflationary and hyperinflationary episodes during the 20th century demonstrated, this is not an ideal state of affairs."

Satoshi echoes Szabo in his first forum post:

"The root problem with conventional currency is all the trust that's required to make it work. The central bank must be trusted not to debase the currency, but the history of fiat currencies is full of breaches of that trust."

Szabo published a comprehensive research study in 2002 on the history and ethnography of money titled, "Shelling Out: The Origins of Money." This is certainly the type of work Satoshi would have undertaken before Bitcoin.

Importantly, in Szabo's aforementioned 2011 blog post, he suggested that his paper on the origins of money should be required reading for people debating the economics of Bitcoin:

"Gold couldn't work as money until it was already shiny or useful for electronics or something else besides money, they told me. (Do insurance services also have to start out useful for something else, maybe as power plants?) This common argument coming ironically from libertarians who misinterpreted Menger's account of the origin of money as being the only way it could arise (rather than an account of how it could arise) and, in the same way misapplying Mises' regression theorem. Even though I had rebutted these arguments in my study of the origins of money, which I humbly suggest should be required reading for anybody debating the economics of Bitcoin."

Szabo fundamentally argues in his economic theory that the "unforgeable costliness" of certain objects, such as rare shells, makes them reliable as a medium of exchange and store of value. Thus, he proved that sound money does not require intrinsic value, as mentioned in the above quote.

Satoshi applied Szabo's theory in Bitcoin's design through mining (establishing provable, unforgeable cost), and its digital aspect, showing that intrinsic qualities like gold's shine are not necessary for Bitcoin to be the best money in history.

These are the precise reasons behind Szabo considering his work to be required reading for Bitcoin. As a matter of fact, in a little known 2018 interview at Francisco Marroquín University, Szabo stated:

"Well, the term mining came about with the analogy to gold mining... so, my economic theory that I applied to Bit gold, and that I... or some people at least applied to Bitcoin."

Also, a financial researcher penned a well-written piece showing again how Satoshi was utilizing Szabo's unique economical arguments through his description of a non-aesthetic metal, coming to the conclusion:

"There are very few economic philosophers in the world today that can be caught giving an academically based argument for WHY Bitcoin should have value. Szabo and Satoshi each give essentially an identically unique explanation."

Furthermore, Satoshi discussed politics, despite what many people think. He is a libertarian like Szabo, stating:

"It's very attractive to the libertarian viewpoint if we can explain [Bitcoin] properly."

In addition, Satoshi had experience in smart contracts:

"The design supports a tremendous variety of possible transaction types that I designed years ago. Escrow transactions, bonded contracts, third party arbitration, multi-party signature, etc."

Nick Szabo invented smart contracts in the 90s, as previously noted.

Daniel Nagy, the cryptographer whose digital cash design inspired Szabo in 2007, even stated Bitcoin scripts are smart contracts in Szabo's famous 2011 blog post:

"In my opinion, [Bitcoin] has not one, but several outstanding ideas in the ways of combining well-known cryptography. Yet, I believe that it is a bubble that is going to burst due [to] some crucial deficiencies.

Strokes of genius include:
- The formal language used to describe transaction details. Smart contracts right there!

As previously stated, Satoshi was strongly motivated by the idea of scarcity when designing Bitcoin, exactly like Szabo. Satoshi explained his thought process in the above 2009 email. Noticeably, in the Bit gold draft discussed earlier, Szabo emphasized Bit gold's scarcity when responding to a comment by Hal Finney:

What's more, Satoshi appeared to support the existence of altcoins in writings such as below:

Strikingly, Szabo is one of the few Satoshi candidates who likes some altcoins in addition to Bitcoin (such as Monero). One reason for this is that Szabo invented smart contracts, which are a great deal of altcoins. Also, having studied the history of money in great detail, Szabo understands that many types of scarce objects existed throughout history.

Szabo's vision from the start was for this to be recreated in the digital world for the masses; different types of coins serving different purposes:

Notably, two Bitcoin researchers conducted an analysis of Satoshi's newly released emails and reached the conclusion that Satoshi was a single US person operating on the west coast, who started programming Bitcoin in January 2008. Szabo happens to reside on the west coast.

Szabo's ideas match Satoshi's early code

As part of my research, I have examined the motivations behind Satoshi's original source code before he made changes in the final version. The most notable change was a virtual poker game that Satoshi removed in the final version of the software.

I discovered that Szabo was interested in virtual poker. In an October 1993 Cypherpunks email, Szabo stated:

"My own vision of cypherpunk evolution runs along the following lines... online markets: Internet video poker, election outcome markets, satellite track betting, etc."

Furthermore, I found another remarkable similarity in ideas between Szabo and Satoshi regarding the initial code.

In Satoshi's early source code, he programmed an unfinished digital marketplace, which he later described in an email to core developer Mike Hearn as an "eBay style marketplace":

"I was trying to implement an eBay style marketplace built in to the client."

Strikingly, Szabo highly respected eBay's design in his extensive research paper on the origins of money:

"It is no coincidence that markets in rare objects and unique artwork – usually sharing the attributes of collectibles described above – have enjoyed a renaissance during the last century. One of our most advanced high-tech marketplaces, eBay, is centered around these objects of primordial economic qualities."

Immensely similar writing and coding styles

Fittingly, Nick Szabo is often shown as having the most similar writing mannerisms to Satoshi. A group of 40 final year Aston University stylometry students, led by Professor Jack Grieve, stated in a 2014 study of the whitepaper:

"The number of linguistic similarities between Szabo’s writing and the Bitcoin paper is uncanny, none of the other possible authors were anywhere near as good of a match. We are pretty confident that out of the list of people regularly referred to as possibilities, Nick Szabo is the main author of the paper, though we can’t rule out the possibility that others contributed."

While there is a decent probability that Satoshi consulted others for assistance, the important part of the study was the conclusion that Szabo was the main author of the whitepaper.

Furthermore, another researcher wrote a stylometry paper in 2017 about Satoshi, and reached the conclusion that Szabo was the most similar.

In 2016, a computer science researcher conducted an analysis of several leading candidates' code and found that Szabo showed a intriguing similarity to Satoshi (commenting style), which the others didn't.

Later research has shown James Donald (not in the aforementioned analysis) also shares this similarity. However, while still a stronger candidate than most, Donald famously spoke to Satoshi using his public identity, while there is no known correspondence between Szabo and Satoshi.

Szabo's OPSEC skills are extraordinarily strong

When people began to speculate on the identity of Satoshi Nakamoto, Nick Szabo was the first person suspected. By examining the principles of Occam's Razor, it's easy to understand why.

Szabo's OPSEC skills are so strong that people theorized in 2011 that he didn't exist, suggesting his name was an alias for famous mathematician John Nash.

Just like Satoshi, Szabo is an experienced user of pseudonyms. In 1993, while communicating on the cypherpunk mailing list, Szabo described his frequent use of pseudonyms:

"In my limited experience creating Internet pseudonyms, I've been quite distracted by the continual need to avoid leaving pointers to my True Name lying around -- excess mail to/from my True Name, shared files, common peculiarities (eg misspellings in written text), traceable  logins, etc.... The hazards are everywhere."

Furthermore, Szabo stated in a 2006 blog post:

"Another good use for pseudonyms [is] to stay alive."

There is evidence suggesting that Satoshi may have faked his British writing mannerisms for the purposes of OPSEC.

Researchers determined in a study that Satoshi's language use was highly erratic, and he actually used both British and American English often, contrary to popular belief. In fact, Satoshi even used American English alongside British English within the same posts and emails at times.

Given this evidence and Satoshi's many other precautions, it appears highly likely that his semantics were another red herring.

Satoshi had a deep respect for Hal Finney, Szabo's good friend

Satoshi Nakamoto sent the first Bitcoin transaction to Hal Finney. It is possible this may be simply due to the fact Finney loved the idea. However, when you consider the broader picture, it is truly odd that Finney happened to be the second user of Bitcoin when he and Szabo were working on Bit gold-related ideas for years prior.

When discussing the software with another individual on the Bitcoin forum, Finney stated:

"I'd like to hear some specific criticisms of the code. To me it looks like an impressive job, although I'd wish for more comments. Now I've mostly studied the init, main, script and a bit of net modules. This is some powerful machinery."

Satoshi replied:

"That means a lot coming from you, Hal.  Thanks."

This is notable because, while he still thanked other Bitcoin core developers, Satoshi did not appear to say anything along the lines of "coming from you," to anyone but Finney. The deep respect expressed by Satoshi implies he knew Finney before the creation of Bitcoin, lining up flawlessly with Szabo's friendship with Finney.

"bit coin" appeared in a comment referring to Bit gold on Szabo's blog 6 months before the whitepaper

A user named "Eddie" used the term "bit coin" to refer to Bit gold multiple times in a comment on Szabo's important blog post "Bit gold Markets," which was written 6 months before the Bitcoin whitepaper:

It is unclear why Eddie suddenly used that crucial term while also combining "bitgold" and using the correct spelling, "bit gold," too. A few possible answers are: they were typos, or he thought it was a better name. Crucially, since this was Szabo's blog, it means he saw Eddie's comment before the term "Bitcoin" even existed under Satoshi's identity.

A Satoshi Easter egg was a motivation for Szabo

Besides the fact that Bitcoin is an obvious attempt to mirror a scare commodity like gold in the digital world, mysterious references by Satoshi show that he was highly motivated by gold. Satoshi listed his birthday on the P2P foundation forum as April 5th, 1975.

April 5th, 1933 happens to be the day US President Franklin D. Roosevelt signed Executive Order 6102, which made it illegal for Americans to own gold. In 1975, the US government reversed this policy, allowing Americans to own gold again.

Stunningly, Szabo mentioned FDR's gold ban on his blog exactly 10 days before Satoshi registered the bitcoin.org domain. In addition, Szabo frequently has referred to the same event as a motivation for his work in many speeches.

The hints

Nick Szabo tends to stay away from the topic of Satoshi; but occasionally, despite some denials, (which many expect Satoshi would do), he reveals things that suggest he knows far more about Bitcoin's creation than he's stated. It is important to remember that there is nothing publicly tying Szabo to the development of Bitcoin.

When former NYT journalist Nathaniel Popper (previously mentioned) approached Szabo at a dinner party to probe his involvement in the creation of Bitcoin, Szabo told Popper:

"I mean, the reason people tag me is because you can go through secure property titles and bit gold — there are so many parallels between that and Bitcoin that you can’t find anywhere else."

Szabo's comments to Popper led former Gizmodo journalist Kate Knibbs to famously state in an article:

"Even Nick Szabo thinks that Nick Szabo is probably Satoshi Nakamoto."

On Twitter, when making a tweet about his "old cryptocurrency design called bit gold," one user asked:

"Then what is your new design?"

Szabo curiously responded with:

"Bit gold II"

Further building on the above statements, when a Twitter user asked Szabo why Bit gold failed, Szabo replied:

"It's much easier to run actual software than a design for software."

Most impressive, in Szabo's 2011 blog post extensively described above, he stated:

"Myself, Wei Dai, and Hal Finney were the only people I know of who liked the idea (or in Dai's case his related idea) enough to pursue it to any significant extent until Nakamoto (assuming Nakamoto is not really Finney or Dai). Only Finney (RPOW) and Nakamoto were motivated enough to actually implement such a scheme."

Szabo himself was among the only three people he listed to like the idea of a decentralized cryptocurrency like Bitcoin. Through his reference to RPOW as a variant of Bit gold, Szabo is hinting that himself and Hal Finney were the only ones motivated enough to create Bitcoin.

Crucially, you'll notice that both Finney and Dai have known communications with Satoshi, while Szabo does not.

Crypto leaders seem to understand

The smartest individuals in the crypto space know a great deal about Nick Szabo since he invented smart contracts and Bit gold. However, it goes much further than that. Computer scientists are individuals who typically place empirical evidence above other factors.

The creator of Litecoin, Charlie Lee, stated in 2017:

"In my opinion, Nick Szabo is the closest we have to Satoshi, if not Satoshi himself." 

As the creator of Litecoin (a well-known Bitcoin fork), Lee is highly familiar with the technology behind Bitcoin.

In a blog post penned by Emin Gun Sirer, titled, "How to Spot Satoshi," the former Cornell professor and computer scientist who founded Avalanche, reached a fascinating conclusion about Satoshi:

"Interestingly, I have come across one person who was a perfect fit. That person had the precise same intellectual signature as Satoshi, someone who could have written, word for word, some of Satoshi's forum posts. Is that person Satoshi? Well, most likely, though there is a tiny probability that they are instead an intellectual doppelganger."

This led to comments by readers such as:

"I can't help but wonder if you're obliquely referencing Nick Szabo in this post."

Elon Musk, the wealthy co-founder of PayPal and Dogecoin proponent, famously stated in December 2021:

"[Nick Szabo] seems to be the one more responsible for the ideas behind Bitcoin than anyone else."

This statement by Musk is supported by the fact that Szabo has published over 20 research papers on Bitcoin-related ideas, while most other candidates haven't come close.

The few arguments against Szabo don't hold up

When you look at the many internet discussions speculating on the identity of Satoshi Nakamoto, Nick Szabo is consistently at the top.

However, the most common argument against Szabo being Satoshi is that he has denied it. Though, the chances of Satoshi outright admitting to being the person are likely very low. A candidate denying they're Satoshi does not automatically mean they are not Satoshi. Rather, it is a neutral point.

On another point, some people falsely believe that Nick Szabo has the same birthday as Satoshi's listed birthday (April 5th). This article does not touch on Szabo's real birthday or other parts of his personal life out of respect for his privacy. Regardless, it wouldn't make sense for the person behind the pseudonym to use their real birthday.

In addition, others argue that Szabo is not an experienced enough programmer to be Satoshi. However, Szabo's open source web code says otherwise. That code is not the work of an amateur, but of a seasoned expert.

Furthermore, in a 2017 Tim Ferriss podcast interview, Szabo strongly denied the notion that he was an inexperienced programmer after Naval Ravikant questioned whether he was a "serious" enough programmer to code Bit gold:

Ravikant: "Nick, you only had the theory of Bit gold, you're not a serious enough programmer to create Bit gold."

Szabo: "Well, I am a serious programmer, but.... I.... didn't get around to programming Bit gold."

Also, you'll notice that Szabo, like other times, gave no concrete reason as to why he didn't code Bit gold, despite having the skills. In addition to the above evidence, Szabo's extensive computer science education and status as a lead cypherpunk shows that the notion he didn't possess the abilities to program Bitcoin doesn't match the evidence.

Author and journalist Dominic Frisby revealed in his famous 2014 book, Bitcoin: The Future of Money?, that Szabo said to him privately:

"C++ is a great language for implementing cryptographic primitives because of its efficiency."

Szabo's statement implies that he has coded with C++ in the past. Logically, the real Satoshi would hide his C++ code from the public due to obvious reasons. Based on his extensive analysis, Frisby concluded that Szabo was Satoshi. Even still, it cannot be ruled out that Satoshi consulted multiple people in his inner circle for advice on the design, including the coding.

The last common argument is that Szabo stopped using double spaces in his online texts after the 90s, but this is a misconception. Szabo has never used double spaces on his blog to begin with, which many people incorrectly think is the only public work he published after the 90s. The above 2005 email shows Szabo using double spaces while discussing how RPOW is a working version of Bit gold.

Szabo is Hungarian-American and the first Satoshi Statue is in Hungary

Of all the places on Earth for the first Satoshi Nakamoto statue, Hungary was peculiarly chosen. Szabo's father was a Hungarian who opposed the communist regime in the 50s and immigrated to America for freedom. This has inspired Szabo throughout his life, especially for his work to create a secure financial system untethered from government.

It is a remarkable coincidence that the first Satoshi statue was installed in a location with strong ties to Szabo's background.

Conclusion

Bitcoin has revolutionized the global financial landscape, providing millions of previously unbanked individuals with access to trust minimized financial services. Satoshi Nakamoto is a visionary who did an incredible job at hiding his identity from the world.

The evidence presented in this article demonstrates that Satoshi appears to be a single highly motivated person. Although, it can't be ruled out that he asked for assistance.

When people discuss the identity of Satoshi Nakamoto, he is often referred to as a humble genius with a mastery of economics and computer programming. Nick Szabo is the only candidate to identically match the unique personality of Bitcoin's inventor. Based on the above research, I conclude that Nick Szabo is the real Satoshi Nakamoto.
