They should do it in a way it can't be tampered ever again, just like Bitcoin, and they should become nameless, unknown and walk away just like Nakamoto walked away.
I know its not easy but by now we should have this done already, instead, both old and upcoming developers are running after money since crypto space is the new gold rush, no one wants to make real sacrifice like Nakamoto did.
This is the reason why Bitcoin is different from all other crypto coins out there, no one is ready to make sacrifices without wanting something back, without their names be heard and them available to take the credits, of cos, the centralized entities will crawl in. Shame.
People are too greedy. Centralized is more profitable to an individual because they can control the profit going into their pocket. A decentralized system would mean they have no control over it.
