Creator of Bit Gold and smart contracts
Identity hypothesis →Nick Szabo is a computer scientist, legal scholar, and cryptographer known for his pioneering work on digital currency and smart contracts. His real identity and background remain largely private.
In 1994, Szabo coined the term “smart contracts” — self-executing agreements with the terms directly written into code. This concept, decades ahead of its time, would later become the foundation of platforms like Ethereum.
In 1998, Szabo conceived Bit Gold, a decentralized digital currency system based on proof-of-work. He published the full design on his Unenumerated blog on December 29, 2005. Bit Gold addressed the fundamental problem of creating digital scarcity without a trusted third party — the same problem Bitcoin would solve. Szabo later reflected: “Nearly everybody who heard the general idea thought it was a very bad idea.”
Bit Gold shared key concepts with Bitcoin — proof-of-work, chained puzzles, and decentralized verification — but had a significant security weakness: it did not solve the problem of preventing a single party from controlling the majority of nodes. Satoshi Nakamoto improved on this design.
Szabo acknowledged Satoshi’s improvement in his 2011 blog post: “Nakamoto improved a significant security shortcoming that my design had, namely by requiring proof-of-work to be a node in a Byzantine-resilient peer-to-peer system to greatly reduce the threat of an untrustworthy party controlling the majority of nodes.”
Hal Finney, in his early email exchanges about Bitcoin, noted the similarity between Bitcoin and Szabo’s Bit Gold. Satoshi discovered Szabo’s work through Wei Dai, who suggested reviewing Bit Gold alongside his own b-money concept.
The deep conceptual similarities between Bit Gold and Bitcoin, the absence of any published direct Szabo–Satoshi correspondence, and Szabo’s prolific Unenumerated writing during 2007-2008 have made him a recurring Satoshi-identity candidate — documented in the Szabo = Satoshi hypothesis entry, with the Skye Grey / TechCrunch 2013 stylometric articulation, the Aston University 2014 study, and the Popper / NYT 2015 Digital Gold excerpt as the principal supporting articulations, and Szabo’s consistent denials (e.g. “I’m afraid you got it wrong” to Dominic Frisby, 2014) as the principal counter-evidence.

On his Unenumerated blog, Nick Szabo asks for help implementing bit gold — his 1998 digital currency design. No one publicly responds. Six months later, Satoshi publishes the Bitcoin whitepaper.
Editorial reading of Satoshi's relationship to cypherpunk, from three primary observations: he didn't know b-money, Wei Dai testified Satoshi was "not previously active," alignment with Hughes 1993.
Comparison of recurring Satoshi candidates aligned in a seven-dimension profile table. The Individual column links each candidate's hypothesis page; this entry names no leading candidate.
Nick Szabo discusses why Bitcoin took so long, the similarities and differences between bit gold and Bitcoin, and why "nearly everybody who heard the general idea thought it was a very bad idea."

On December 1, 2013, blogger Skye Grey published Satoshi Nakamoto is (probably) Nick Szabo — the first public stylometric study naming Szabo as Satoshi, reported by TechCrunch on December 5.
Aston University Centre for Forensic Linguistics released Project Bitcoin (April 2014): a stylometric study under Jack Grieve naming Szabo as the most likely whitepaper author among 11 candidates.
On May 15, 2015, the New York Times published Nathaniel Popper's Decoding the Enigma of Satoshi Nakamoto — a Digital Gold excerpt naming Bit Gold designer Nick Szabo as Satoshi. Szabo denied it.
Hal Finney's RPOW system, a 2004 prototype for reusable proof-of-work tokens, gains posthumous recognition as one of Bitcoin's most important direct precursors.
