Puzzle 129, 134, 139, 144, 149, 154, 160 are already solved, this means that this puzzle is rigged, but anyway, is it harder to solve puzzle 66 than mining a block?
-snip-Just look the hashs on blockchain, all mentioned hashs already have outs, how could a hash with unknown privatekey has outs?
Puzzle numbering starts with '1'.
But inn Bitcoin's blockchain, output_index starts with '0'.
So you're looking at the wrong outputs, you meant 130, 135, 145, 150, 155, 161 respectively.
The reason why those have spent outputs already is because the owner decided to reveal the public keys of puzzles divisible by '5' as "
bonus".
And 161~256 are spent because the owner deem that those are computationally impossible to bruteforce.
