Bitcoin is the first implementation of a concept called "cryptocurrency", which was first described in 1998 by Wei Dai on the cypherpunks mailing list, suggesting the idea of a new form of money that uses cryptography to control its creation and transactions, rather than a central authority. The first Bitcoin specification and proof of concept was published in 2009 in a cryptography mailing list by Satoshi Nakamoto. Satoshi left the project in late 2010 without revealing much about himself. The community has since grown exponentially with many developers working on Bitcoin.
Who created bitcoin was an Australian man named Craig Wright who recently revealed himself as the creator of Bitcoin. Wright's acknowledgment of three well-known international media finally revealed a bit of a puzzle about Bitcoin.
one of the proofs that corroborates Wright as a Bitcoin creator is that the messages he sent are digitally marked using cryptographic keys created at the start of Bitcoin development
