Story

What the post asked, what the answer turned out to be, and what the chain says happened. The record below holds the data.

Conclusive proof

"I am looking for conclusive proof that someone named Craig ... is Satoshi." Extremely hard, the post warns.

Two capital letters, AI, and the field is in both names. Absolutely conclusive, the author says. Nine hours.

There was a second prize too, 5 mBTC for the best comment. The next post says the author didn't like judging it.
