Thanks for sharing this incredible knowledge .. but I fail to understand how the uniqueness can be ensured .. I mean how can anyone say with any confidence that npub and nsec is a unique combination .. (doesn't matter if it is BTC or nostr network ) ..

Saying this because to ensure uniqueness , there must exist a database of all the npub and nsec combinations .... Which means someone needs to know all the combinations .. which is obviously impossible and defeats the very purppose ! ..

But without a database , no one can ever be sure that no two npubs have same nsec !
