using the bitcoin hash as a tiebreaker between forks does create an external mechanism, but i dont see how the attacker is prevented from making a chain that is preferred. In fact, if this isnt prevented using verihash would just make the attack much more effective

Hello and welcome. Yes, a 51% attack is still possible and even so with storing data of any type on the Bitcoin blockchain like Veriblock does. A scoring system does not alleviate that either. I will rewrite the readme until/if any solutions are found. This simple idea originated solely to confront Veriblock and has gained enough traction for this repository to exist to see if any solutions to risen issues can be found.
