Story

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

Next after no

"Can you find the solution with absolutely no hint whatsoever?" Third time this question shows up. Now it wants a single capital letter.

The obvious first step is "no". N and O follow each other in the alphabet, so the next one is P, and the field is next after no. Almost four hours, the longest of the three.

The update misquotes the field as "next to no". Then the author checks the journal, prints the full MD5 and the WIF, and fixes it.

officialQuestion: Can you find the solution with absolutely no hint whatsoever?

Published answer
Solution for this was P, the method behind it was taking the obvious first step "no" and then noticing that the letters in "no" are following each other in the alphabet, which makes P the next one.

BFUB was not "next to no" but "next after no".
