Author here. I built this once learning about front running the Bitcoin puzzles.

seems cool -- wasn't there that guy searching through a trash heap for years searching for his thumb drive? guessing he didn't have the public key, or if he did this would've fixed his situation?

You may have missed this part:

> What this does not show

> The attack above depends on conditions that ordinary Bitcoin keys do not meet.

> Ordinary Bitcoin keys are not affected by any of this

> A properly generated private key is spread across roughly 2 to the power of 256 possibilities. The square root of that is 2 to the power of 128, which is not attackable by anyone, with any budget, ever.
