What the creator should do is send 1 btc to me🤣...
Seriously speaking, the creator must reveal the solved puzzles that were emptied, because what do we know if, for example, the puzzles are not in the range we believe? If he had a mistake when creating 256 puzzles (he corrected it, years later), he could having made the mistake of putting some keys in other ranges, or worse still it could be a big joke and he himself has emptied the last unrevealed puzzles to buy a Ferrari🤪.
hahaha two bad jokes in a single post, bravo.
This process can be automatized and the probabilities of error are zero after some tests.
The logical thing is that he did it manually, because it would not make sense to create an HD wallet, take the pk and then pass them through a 256-step script to obtain the desired ranges. If a script were made, an HD wallet would simply not be chosen, it would be generated the pk randomly to avoid the task of taking the pk from the wallet and modifying them as desired.
Or would you as a programmer not do it like that?
