If the signature provided is actually valid, then @RetiredCoder may have some connection with the creator of this puzzle. I believe what really happened is that when the creator realized he messed up the timing and decision to remove puzzles 120, 125, and 130, he decided to offer the puzzle-solving community a “lollipop” (mini puzzle) as a way to make up for it.
In his previous post, @RetiredCoder mentioned having 20 RTX 4090 GPUs and claimed to have used the kangaroo algorithm to solve the puzzle. But, realistically, does anyone here believe it’s technically possible to crack 130 bits in just two months?
