Story

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

Great deeds

June 5, 2019. The question is Great deeds. The solution is one word with a capital first letter, plus a TOMI field. Digits 72f, 8 and c. Hints come fast this time, 20 and 40 minutes after the post.

The author asked what hint people wanted, got a split vote and tossed a coin. Hint one: "with little". Hint two: the TOMI format is [name] [number].

Riddle number 4

Search "Great deeds with little" and you find it. Riddle 4 of the hundred riddles of Symphosius.

Great deeds with little strength I do,

I close the open, ope the closed for you.

The answer is Key. What else would a Bitcoin quiz pick? The TOMI field is the author's name and the riddle's number.

The claim confirmed at 04:50:56 UTC, 50 minutes after the post. Fast hints, fast solve.

Symphonius or Symphosius?

The author's update says Symphonius. u/puzzleponky spotted it. The poet is Symphosius, "good thing you did not make that mistake in the actual puzzle". The author fixed the update.

The chain agrees. Key TOMI Symphosius 4 hashes to 72f, the digits the post gave, and derives the address the claim spent. Key TOMI Symphonius 4 hashes to d39. Typo in the post, not in the puzzle. Phew.
