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.
