Hey, new to Bitcoin but I have a question that one of you may be able to help me understand.

Given the unfortunate event of puzzle#66
{
  the real solver likely panic and tried to sweep the WIF using electrum (34 inputs and paying only 5.217/B)

  the sniper within a minute made a clean TX (1 input and paying 406.356/B)
}

If saatoshi_rising used a static padding for low entropy puzzles (like #66)

-> "123456789abcdef123456789abcdef123456789abcdef12" + [2832ed74f2b5e35ee]

Would a sniper still be able to find the private key from the public key being exposed in the mempool within 2 block confirmations?

From my limited understanding this would not be possible because the pubkey would be from a 256-bit key, but maybe I am missing something.

Thanks!
