BTW2: adding a little bit of serendipity to this Sunday I came up with this repository [1] which seems very dangerous and fishy. It says that "34 000 Satoshi Nakamoto wallets with pubkeys (50 BTC each other)" but the download points to a .zip with an .exe. In GitHub you can denounce people but do you suggest to investigate the .exe before right? Seems like a good, and probably simple, reversing play.
On the context of Satoshi's public keys, you cannot (like some other blockchains) get his/her/their public keys from the address.
