Nostr is reasonably well decentralized. I dont think it's DINO.
It's not decentralized like paper.
Every system, by definition will have constraints, or it would not be a system. For example, Tim Berners-Lee once said, all specifications are a form of centralization.
What is important is what contstraints are applied. And whether it lets you work. Or blocks you from working.
Figure these things out, and the rest of the design becomes much easier.
Hmm what constraints are you most worried about? What do you think needs to be improved?
As I say, nostr is quite good (or i wouldnt have worked on it).
Scalability. Data models. Clean separation of data and meta data. Clean separation of data and transport.
You also need a monetary system that is not centralized. For example no centralized premine, like most have. This can facilitate a free market a layer above.
A company that operates on a free market can issue shares in that company. A company that issues shares on a rigged system is constrained and DINO.
And so on ...
