Somehow aggressive in your topic here. Or many people simply don’t want someone else to try to hack it. Or, they're just people like that. In general, I understand that the puzzle was created not to try brute force, but to test the elliptic curve itself. In order for you to try to hack it, the public keys were revealed to you.
One could calmly answer that there are a lot of numbers on the curve that it accepts as 0. That there are also numbers that it does not accept at all. I’m not good at it myself, but now I’m reading the documentation and studying it. And one thing I see is that there cannot be a number that she will not accept. But such numbers exist precisely in 256k1; in others I checked there are no such numbers. This means that this error was inherent from the very beginning.
Well, I won’t post the numbers themselves just yet, since there will be a smarter person than me who will just quickly hack everything himself. And if this really poses a threat to the curve, then the disclosure of this information will collapse the entire crypt to 0. But I don’t want to just invest effort, I want to save a little money before that.
