Satoshi Nakamoto: The mystery of the Bitcoin architect and its unit of account

When we talk about Satoshi, we refer to two concepts: the mysterious creator of the first cryptocurrency and the smallest unit of Bitcoin. This duality reflects one of the most intriguing stories in the world of financial technology — on one hand, an attempt by developers to facilitate calculations, and on the other, a century-old mystery of an individual who forever changed the landscape of digital assets. Let’s explore how this name came about, why it was chosen this way, and what theories exist about who is behind this pseudonym.

Satoshi as a monetary unit: when Bitcoin needed subdivision

Any currency in circulation has a certain denomination and a mechanism for division. In Russia, a kopeck is one-hundredth of a ruble; in the US, a cent is one-hundredth of a dollar. Satoshi Nakamoto, designing Bitcoin’s architecture, envisioned a similar system, but with a much smaller subdivision.

In the early stages of cryptocurrency development, such division was simply unnecessary. For example, in September 2009, 5,050 bitcoins were sold for $5.02 — at that time, the asset’s price was so low that talking about tiny fractions was premature. However, just a year later, on the Mt.Gox trading platform, the price of Bitcoin rose to $0.50, and a cryptography forum participant under the nickname ribuck first proposed introducing a minimal subdivision unit — 1/100 BTC. The initiative was initially met with little enthusiasm, as the need for it had not yet matured.

The situation changed dramatically in early 2011, when Bitcoin’s price doubled and first reached $1. It was at this moment that the community revisited the idea of ribuck and agreed on the necessity of introducing micro-units. Naming them after the creator of the cryptocurrency was both logical and symbolic — thus, Satoshi became both a memorial and a functional unit.

However, the developers chose a ratio of 1 to 100 million, not 1 to 100 as in traditional currencies. This demonstrated remarkable foresight on the part of Bitcoin’s architects — they already recognized the potential for exponential growth in the value of the first crypto asset. Today, the subdivision system looks like this:

• 1 Bitcoin (BTC)
• 1 Bitcoin (Ƀ) — 0.000001 BTC
• 1 Satoshi — 0.00000001 BTC
• 1 millisatoshi — 0.00000000001 BTC

The practical purpose of Satoshi is to facilitate everyday calculations. As Bitcoin’s price has risen to tens of thousands of dollars over time, valuing small goods and services in whole BTC has become inconvenient and visually impractical. Satoshi allows users to operate with numbers that are easier for human perception.

Practical ways to obtain Satoshi: from trading to mining

Since Satoshi is part of Bitcoin, acquiring it is fundamentally no different from buying BTC itself. Several standard channels are available:

Purchasing on cryptocurrency exchanges — the most popular method, where you can exchange traditional currency for digital assets. Major platforms offer user-friendly interfaces and various trading pairs.

Using online exchangers — a quick way to convert without registering on a full-fledged exchange. This option is often chosen for its simplicity.

P2P payments — direct transfers between users, providing greater flexibility in transaction conditions.

Direct receipt in a crypto wallet — a feature offered by some asset management apps.

An alternative way to obtain Satoshi is mining — the process where network participants solve complex cryptographic problems and are rewarded with new bitcoins. However, mining has now transformed into a high-tech, capital-intensive industry with significant entry barriers. For profitable mining, specialized equipment (ASIC miners), access to cheap electricity, and often membership in mining pools are required.

The mystery of the identity: who is behind Satoshi Nakamoto

Currently, the true identity of Bitcoin’s creator remains one of the most captivating unsolved mysteries in technological history. Despite numerous investigations, theories, and assumptions, none have received definitive confirmation. Around this question, a whole meta-narrative of hypotheses has formed, each with its supporters and detractors.

From Dorian to Craig: main theories about Bitcoin’s creator

In 2014, the American publication Newsweek published an investigation claiming that the real creator of Bitcoin was Dorian Satoshi Nakamoto, a 64-year-old American of Japanese descent. This coincidence of names was too superficial as proof. Dorian was indeed a programmer, worked on secret defense projects, and was an engineer at financial and tech companies in Los Angeles. However, shortly after the publication, he issued a clear denial, stating he had nothing to do with the development of the cryptocurrency.

After Dorian was ruled out, attention shifted to another candidate — Hal Finney, a computer scientist and one of the pioneers of cryptography. The coincidence was more compelling: Finney lived near Dorian and, critically, was the recipient of the first Bitcoin transaction in history. This fact seemed strong evidence of his involvement. Nevertheless, Finney vehemently denied this hypothesis until his death in 2014.

The next prominent candidate was Nick Szabo, a researcher in computer science and cryptography, known for his work on decentralized systems. His candidacy received interesting support: researchers from Aston University in Birmingham conducted a linguistic analysis of Szabo’s articles and letters, comparing them to the Bitcoin White Paper, and found striking similarities in style and terminology. Despite this, Szabo denied involvement, and the level of evidence was insufficient for a definitive conclusion.

In 2015, a new development emerged — entrepreneur Craig Wright claimed to be Satoshi Nakamoto and the creator of Bitcoin. Unlike other candidates, Wright did not hide and actively promoted his version. However, when asked to provide cryptographic proof (signing messages with the private keys of the first block), Wright was unable to convincingly demonstrate it. Subsequently, technical rebuttals of his claims appeared online, and Wright’s version lost credibility.

Another name proposed was Dave Kleiman, a programmer, former military, and investigator. Kleiman had been paralyzed since 1995 and died in 2013 from an infectious disease. However, this theory remains a hypothesis without convincing evidence.

Why does the mystery remain unsolved

The persistence of this mystery is explained by several factors. First, Satoshi Nakamoto himself virtually disappeared from the public eye after the initial years, leaving Bitcoin’s development to the community. Second, cryptographic technologies that could serve as conclusive proof require voluntary disclosure of private keys — an act that would inevitably reveal the identity but also threaten the vast amounts of accumulated bitcoins. Third, the possibility that Satoshi Nakamoto is a pseudonym for a group of developers rather than an individual has never been fully ruled out.

Thus, the identity of Satoshi Nakamoto remains the greatest open mystery in cryptography and financial technology. All available theories contain elements of plausibility and gaps simultaneously, giving this question an archaic, mystical character — a secret that the world will likely only learn if Nakamoto (or they) decide to reveal their identity.
