First I have to say this is my opinion, not necessarily the plan for Cryptape, nor the Nervos foundation: my feeling is that OTX processor will still first come in the form of software running by entities other than miners. Yes there will be shared state problem, but at least we can get the ball start to roll, simply retrying could get OTX processors to work. Miners might only start to adopt OTX processors with enough usage and incentives. And even after that, there might still be use cases of independent OTX processors(think MEV bots in ETH world), but I cannot be sure here.
