Satoshi is dead, unfortunately.

He died, yes. But then He rose again.

Unfortunately they sealed the tomb with a cryptographically-secure boulder this time and they've been waiting patiently in the dark for someone to decipher the pattern in the public keys so they can be released.

(Obligatory disclaimer: this is a joke, do not go making a religion out of this.)

But was it military-grade encryption?

Who was it, do you think?

My money's on Hal Finney.

How do you reconcile this with the fact that Satoshi sent both an email and a bitcoin transaction while Hal was busy running a 10 mile race? https://news.ycombinator.com/item?id=37974155

Most likely Szabo.

There's no way it was Szabo, although Szabo likes people to think it was him. Szabo's ideas for p2p currency were directly opposed to the structure of bitcoin, and he continued professing these views and critiques of bitcoin long after bitcoin was launched and achieved some measure of success.

Wait, is Nick Szabo dead? I find conflicting information on the Net.
