Story

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

Z

This block never really got a question. After Y for block 25, someone guessed Z for block 26, watched the chain and claimed it in the same Bitcoin block as its funding. The post came after the money was gone.

So the post is just a report: "There was someone." Fair enough.

Published answer
Answer for this one was Z, as this is the last occasion to do a single letter answer.
