if yall plan to post/use keyspaces searched by other people (lot of trust has to go into that) set up a python program that randomly searches whatever sized range and then print that range to a file; rinse and repeat. And then it's just a matter of posting your ranges somewhere for others to view.
As we all know, it is a huge undertaking as the td pool had searched 15%+ of the 64 key and still did not find it before someone else did.
