What if... someone inside Mara is aware of this challenge/addresses with weak privatekeys and had access to that private mempool?
Is hard to trust in this services.
So for all those users who said they've found the key this is the fire test to prove it.
I don't see many options for someone to try to intercept a transaction even if it is with a weak private key, in any case, the biased employee would have to make the transfer in the same way, using the MARA pool, as there would be no time for him to look for another pool, because if he does it openly he will lose the BTCs, that is, the employee only has to lose, whatever he does, it will be discovered, because from the moment you send a transaction it would be exclusively their responsibility to keep your data safe.
