• October 31, 2008: Satoshi publishes the Bitcoin whitepaper, titled "Bitcoin: A Peer-to-Peer Electronic Cash System". The paper outlines a decentralized system that uses cryptographic proof and consensus mechanisms to avoid double-spending without relying on trust in intermediaries.

2009: Birth of the Bitcoin Blockchain

• January 3, 2009: The Genesis Block (Block 0) is mined by Satoshi Nakamoto. It contains the embedded message:

"The Times 03/Jan/2009 Chancellor on brink of second bailout for banks"

• July 2010: Launch of Mt. Gox, which later becomes the largest Bitcoin exchange.
• August 2010: A major bug in Bitcoin's code allows a user to generate 184 billion BTC. The network quickly forks and rolls back the transaction — a crucial moment proving Bitcoin’s self-healing capacity.
