1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa is the first address on the Bitcoin blockchain, belonging to Bitcoin's pseudonymous creator Satoshi Nakamoto. On January 3, 2009, Satoshi mined the Genesis Block (block #0), receiving a 50 BTC block reward sent to this address.
The Genesis Block contains an embedded message from The Times: "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks." This served as both a timestamp proof and a commentary on the traditional financial system's instability.
Beyond the original 50 BTC — which is permanently unspendable due to a quirk in Bitcoin's code — thousands of people worldwide have sent small amounts of BTC to this address as a tribute to Satoshi Nakamoto. The address has received thousands of transactions totaling over 100 BTC.
