Setting the scene
Bitcoin's genesis block was mined January 3, 2009, by Satoshi Nakamoto, creating the first cryptocurrency. The block contained the message 'The Times 03/Jan/2009 Chancellor on brink of second bailout for banks,' referencing the financial crisis. Bitcoin was described in a 2008 white paper as peer-to-peer electronic cash.
What happened
Bitcoin introduced blockchain technology—a decentralized ledger secured by proof-of-work mining. Initially worthless, bitcoin reached $1 in 2011, $1,000 in 2013, and peaked near $69,000 in 2021. Satoshi disappeared in 2010-2011.
Why it still matters
The genesis block began the cryptocurrency revolution, enabling decentralized finance and sparking debate about money, trust, and regulation. January 3, 2009, marked the birth of an asset class now worth trillions.
