Just think ahead and you'll see there's no actual _plan_. Just ideas floating around. New PoW means weak and easily hijackable consensus, which means no trust from public. So this _is_ the problem that has no solution as far as we know.
incorrect. These implementations were developed during the uasf event. They're also known attack vectors. You're insinuating that no one has developed any solutions to attack vectors that have been known about since its creation. Which is kinda ridiculous.
Point me there, I will research them. How do they solve energy distribution? It's not that china has the asics - it's that they have the electricity which dominates any PoW by design. So it's unfair for any PoW change even if you assume the security remains as high as on old alg.
