Frequently Asked Questions

Bitcoin was invented in 2008 when Satoshi Nakamoto published the whitepaper "Bitcoin: A Peer-to-Peer Electronic Cash System" on October 31. The network launched on January 3, 2009, when Satoshi mined the genesis block. However, the ideas behind Bitcoin — public-key cryptography, digital cash, proof of work — were developed over three decades starting in 1976.

Several digital currency systems preceded Bitcoin: David Chaum's DigiCash/eCash (1989–1998), e-gold (1996–2008), HashCash proof-of-work (1997), Wei Dai's b-money proposal (1998), Nick Szabo's Bit Gold concept (1998–2005), and Liberty Reserve (2006–2013). Each contributed ideas or lessons that influenced Bitcoin's design.

The cypherpunks were a group of cryptographers, programmers, and privacy advocates who believed strong cryptography was essential for individual freedom. Starting with a mailing list in 1992, key members included Eric Hughes, Timothy C. May, Adam Back (HashCash), Wei Dai (b-money), Nick Szabo (Bit Gold), and Hal Finney (first Bitcoin recipient). Their ideas and tools directly led to Bitcoin.
