Story

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

coming from you

July 4, 2019. An easy one after two hard ones. Three words, coming from you, no TOMI field. Digits a2a.

Three words from where? Satoshi again, of course.

Satoshi once replied to Hal Finney: That means a lot coming from you, Hal. Full sentence, full stop. If Hal is Satoshi, as the author believes, it's Hal talking to himself. The author found that amusing. We do too.

Solved at sight. The claim confirmed at 04:07:03 UTC, under six minutes after the post. u/435627793 found it too: "I was afk for some sec, gg." Seconds matter here.

Published answer
Solution was "That means a lot coming from you, Hal.", which I found remarkable (and amusing in the irony involved) as one instance of Hal talking to himself.
