On January 12, 2009, Block 170 recorded the first person-to-person Bitcoin transfer: Satoshi Nakamoto sent Hal Finney 10 bitcoins.
Bitcoin has no company or central authority in charge of upgrades. For a change to be implemented, it must gain broad support from developers, miners, and node operators.
