Is there a discussion thread somewhere?
There are 18 three digit hexadecimals in the puzzle. If the answer is a permutation of these, then that's just 18 factorial which is 6.4 * 10^15. That is totally bruteforcable without even thinking about the puzzle (and totally worth spinning up a cluster for).
I don't know anything about bitcoin though and 54 characters seems too short to be a private key? You can also brute force 10 more interspersed characters for a slowdown factor of 16^10 * (64 choose 10) = 9.9 * 10^15. So then it's a total cost of 6.3*10^31. Still bruteforceable but more expensive if you're wrong about it.
- ytlty 8y agoFrom the reddit thread, there's some information on how the basic wallet was solved.: https://docs.google.com/document/d/1nUAhlC_n21ZLZcRAHpLw9G--gpk4NUVIJqVp9F68qp4/preview https://docs.google.com/document/d/1nUAhlC_n21ZLZcRAHpLw9G--...
- zawerf 8y agoMan I was totally off on how those hexes are used. Thanks for the link!
- Kiro 8y agoAlso, that's just for the basic wallet with 0.1 BTC in it.
- sometime 8y agoHow out of possibly hundreds of different operations that could take the hex table and and that date in possibly 5 different date formats as arguments, would you find out that it's shift key and YYYYMMDD?
- nothrabannosir 8y agoWild guess: start with shift key "301", see "201" come out. Use an 8 for the next, and it's a 3. Bingo. (I would never in a million lifetimes have guessed that bip thing. How do people even know this?)
- zuck9 8y agoBIP39 and 12 word phrases to backup/restore your wallet is common knowledge in the cryptocurrency community.
- nodesocket 8y agoI think the question is going from decimals to bip39 seed words. Looking at 426 252 813 1535 1935 1603 1068 1479 1168 756 878 1083 I sure as heck would not think, oh that's bip39 indexes.
- Kiro 8y agoNo, you're like 0.01% done.
- imaginenore 8y agoThat's a lot of assumptions. It's a 2944 x 1912 px greyscale image. The real search space is 256^(2944*1912), which is more than the number of atoms in the observable universe. A lot more. EDIT: it's actually not even greyscale, and there's an alpha channel, so it's even worse.
- keyle 8y agoI noticed it on the reddit.com /codes subreddit a couple of days ago. It was already solved for the big prize (310).
