Haven't heard of the man? Here's an executive summary per The Economist:
ON PAPER—or at least on the blockchain—Satoshi Nakamoto is one of the richest people on the planet.... But Mr Nakamoto, though actively involved with his brainchild in its early history, has been silent since 2011. An army of amateur detectives has been trying to work out who he really is, but there is frustratingly little to go on. While developing bitcoin he claimed to be male, in his late 30s and living in Japan, but even that information is suspect.
Will we ever find out his true identity? Speculation abounds. (See here and here and here.) As noted above, Nakamoto is estimated to have more than a million bitcoins, mined very early on. So he'd be worth well over $10Bn at current prices (as of launch), perhaps more. If he hasn't lost his thumb drive.
Question resolves postive if Satoshi's true, corroborated identity is revealed to the world at large by April 5, 2025, his birthday. (Or is it??)
