Story

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

A bribe

The field got a nicer name here: TOMI, Thinking Only Method. The author renamed it in the post at the last minute but hashed with the old BFUB. The post's first line owns up to it.

The question comes from a Book of Swindles story: you want to bribe the author in Bitcoin. 0.777 mbtc to the favorite Yang address. The update writes the address with a lowercase f, the hash has the address itself.

A player saw the BFUB comment first and took the prize.
