1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa — The Bitcoin Genesis Address
1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa is the first address on the Bitcoin blockchain, historically associated with Bitcoin's pseudonymous creator Satoshi Nakamoto; the address alone does not prove private-key control. 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.
