'''Nick Szabo''' is a computer scientist, legal scholar and cryptographer known for his research in [[smart contract|digital contracts]] and [[digital currency]]. He graduated from the University of Washington in 1989 with a degree in computer science.<ref name="Enigma">[https://www.nytimes.com/2015/05/17/business/decoding-the-enigma-of-satoshi-nakamoto-and-the-birth-of-bitcoin.html Decoding the Enigma of Satoshi Nakamoto and the Birth of Bitcoin]</ref> He holds an honorary professorship at the Universidad Francisco Marroquín.<ref>https://noticias.ufm.edu/index.php?title=Graduaci%C3%B3n_UFM_y_doctorado_a_Nick_Szabo</ref>

The phrase and concept of "smart contracts" was developed by Szabo with the goal of bringing what he calls the "highly evolved" practices of contract law and practice to the design of '''electronic commerce protocols''' between strangers on the Internet. Smart contracts are a major feature of [[cryptocurrency]] and the programming language E.<ref>[http://www.erights.org/smart-contracts/ Smart Contracts]</ref>

'''Szabo''' influentially argued that a minimum granularity of micropayments is set by mental transaction costs.

==Bit gold==
{{#ev:youtube|tWuN2R2DC6c|470|right|Nick Szabo on Blockchains and Smart Contracts}}
In 1998, Szabo designed a mechanism for a decentralized digital currency he called "bit gold".<ref name="PeckBitcoin2012">[http://spectrum.ieee.org/computing/software/bitcoin-the-cryptoanarchists-answer-to-cash Bitcoin: The Cryptoanarchists’ Answer to Cash]</ref> Bit gold was never implemented, but has been called "a direct precursor to the Bitcoin architecture."

In Szabo’s bit gold structure, a participant would dedicate computer power to solving cryptographic puzzles. In a bit gold network, solved puzzles would be sent to the Byzantine fault-tolerant public registry and assigned to the public key of the solver. Each solution would become part of the next challenge, creating a growing chain of new property. This aspect of the system provided a way for the [[network]] to verify and time-stamp new coins, because unless a majority of the parties agreed to accept new solutions, they couldn’t start on the next puzzle.<ref>[http://nakamotoinstitute.org/secure-property-titles/ Secure Property Titles with Owner Authority]</ref>

When attempting to design transactions with a digital coin, you run into the "double-spending problem." Once data have been created, reproducing them is a simple matter of copying and pasting. Most digital currencies solve the problem by relinquishing some control to a central authority, which keeps track of each account’s balance. This was an unacceptable solution for Szabo. "I was trying to mimic as closely as possible in cyberspace the [[security]] and trust characteristics of gold, and chief among those is that it doesn’t depend on a trusted central authority," he said.

==Bitcoin speculation==
In 2008, a mysterious figure who wrote under the name [[Satoshi Nakamoto]] released a proposal for bitcoin. Nakamoto’s true identity remained a secret, which led to speculation about a long list of people suspected to be Nakamoto. Although '''Szabo''' has repeatedly denied it, people have speculated that he is '''Nakamoto'''.

Research by financial author Dominic Frisby provided circumstantial evidence but, as he admits, no proof that Satoshi is Szabo.<ref>Frisby, Dominic (2014) "Who is Satoshi Nakamoto?" In Bitcoin: The Future of Money?, p. 85-149. Unbound. ISBN=1783520779</ref> Speaking on RT's ''Keiser Report'', he said "I've concluded there is only one person in the whole world that has the sheer breadth but also the specificity of knowledge and it is this chap...".

Nathaniel Popper wrote in ''The New York Times'' that "the most convincing evidence pointed to a reclusive American man of Hungarian descent named Nick Szabo." In 2008, prior to the release of bitcoin, Szabo wrote a comment on his blog about the intent of creating a live version of his '''hypothetical currency'''.

In 2015, the subsequent [[blockchain]] [[Ethereum]] named a subunit of the Ethereum value [[token]] the "Szabo".
