After 7 years in the crypto space, I'm still not convinced of any particular Satoshi theory. That being said, Nick Szabo, Hal Finney, and Paul Le Roux all have decent evidence pointing to them.
Hal was in the dorm room next to mine at Caltech. It's just like him to be Satoshi. Hal was a great guy, wicked smart even for Caltech, and his sense of humor fits right in with being the anonymous creator. I have no idea about the other two fellows, but my money's on Hal just because I want it to have been him!
I vaguely recall reading about Bitcoin development in ~darknet forums, during 2010-2012. But only vaguely, and I retained no logs. There were hints, I think, that developers were Australian.
Edit: OK, maybe it was earlier. I did say vaguely.
I've been following cypherpunks related stuff since the mid 90s. But I've kept no notes or records. So I don't exactly recall the timeframe. But it was definitely years before the whitepaper. And as I said, I recall hints that developers were Australian.
Actually, perhaps I do have records. But finding them would be nontrivial. I have lots of old FDE drives. But no labels about content, for obvious reasons.
