In my opinion, the status quo systems in crypto are good enough for now until we can find more better ideas that would improve decentralization or take us closer to full decentralization of all of the system components of any of the blockchain networks available right now. From network infrastructures to applications (Smart contracts) built on these networks. Initially, I used to think that Decentralization is easy but then, the demerits like delayed consensus and issues with scalability makes it harder to achieve this. This is why the Blockchain Trilemma is still an unsolved case till date.

A bit of centralization to protect core system resources plus decentralization of other network operations is viable for now. I'm on the lookout for new ideas that might improve decentralization without tradeoffs in security and scalability.
