Story

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

Waste of time, sir

July 15, 2019. The question is a running gag. "Waste of time, sir.", a line players post whenever a block goes wrong. Format [solution] TOMI [TOMI], digits a8f.

Under the post, the author does the math. 838 mBTC in prizes for the first run, 1145 for the second, 777 more for stage two of block 77. "Probably will have wasted my money, but it might just move something."

Madam

After five hours, partial hashes: be for the solution, 07 for the TOMI field. And 07 is the same as yesterday.

u/puzzleponky tried girl and I am a lady first. Then the TOMI hash rang a bell: palindrome again, straight from block 68. The answer is madam. Polite, female and a palindrome. Who calls the author sir?

The claim confirmed at 13:51:25 UTC, under six hours after the post. Brute forced, some said. The author believed the winner.
