Crypto was invented by an anonymous person or group of people under the name Satoshi Nakamoto .

Satoshi Nakamoto is the name used by the unknown person or people who designed bitcoin and created its original reference implementation. As part of the implementation, they also devised the first blockchain database. In the process, they were the first to solve the double-spending problem for digital currency using a peer-to-peer network. They were active in the development of bitcoin up until December 2010.
Nakamoto is estimated to have mined one million bitcoins before disappearing in 2010, when he handed the network alert key and control of the code repository over to Gavin Andresen. Andresen later became lead developer at the Bitcoin Foundation.
Nakamoto’s involvement with bitcoin does not appear to extend past 2010. In April 2011, Nakamoto communicated with fellow bitcoin developer Hal Finney, complimenting him on his code changes and suggesting ideas for improving bitcoin. In late October 2008, Nakamoto published a paper on bitcoin (bitcoin: A Peer-to-Peer Electronic Cash System). This paper detailed methods of using a peer-to-peer network to generate what was described as “a system for electronic transactions without relying on trust”. On 15 August 2008, Nakamoto implemented the bitcoin software as open source code and released it in January 2009.
Wei Dai is a Chinese computer scientist and cryptographer best known for his work on b-money and Bit Gold, proposals for decentralized electronic money and digital gold currency, respectively. He is also the creator of the Crypto++ library.
Nick Szabo is a computer scientist, legal scholar, and cryptographer best known for his pioneering research in digital contracts and cryptocurrency.
Szabo’s work on digital contracts began in the early 1990s with the idea of extending the functionality of electronic transactions to encompass more complex contractual relationships. He formalized this idea in 1996 with the proposal of a decentralized contract registry, which he called “bit gold”.
In 2005, Szabo proposed a design for a decentralized cryptocurrency he called “bit gold”, which was similar to Bitcoin in many respects but never implemented. In 2008, Satoshi Nakamoto published a paper on Bitcoin and pseudonymous creator of Bitcoin. Some have speculated that Nakamoto is a pseudonym for Szabo, but this has never been confirmed.
Hal Finney was a computer scientist and early cryptocurrency pioneer. He is best known for being the first person to receive a bitcoin transaction, as well as for his work on the cryptocurrency platform Bit gold.
Finney was born in 1956 and received his bachelor’s degree in computer science from the California Institute of Technology. He went on to work at Honeywell and then at Xerox PARC, where he was involved in the development of the first personal computer. In 1978, he joined FedEx, where he worked on one of the first networked computers.
In 1987, Finney left FedEx to join PGP Corporation, where he helped develop Pretty Good Privacy (PGP), a data encryption program. He also worked on an early version of the Tor anonymity software.
In 2004, Finney became interested in Bitcoin and began mining the cryptocurrency; he was also an early user of Bitcoin-related services such as e-gold and Bitmessage. In 2010, he was the recipient of the first Bitcoin transaction, which was sent by Satoshi Nakamoto (the pseudonymous creator of Bitcoin).
Finney died in 2014, but his legacy continues to live on through his work in cryptocurrency and privacy-enhancing technologies.
