Of all my dear friends who have replied so far, none has mentioned the obvious. Nostr is the social layer for Bitcoin. It provides "opt in" decentralized verifiability (through social proof) where otherwise only KYC has been possible.
So the killer app for Nostr (and what only Nostr can do) is webs of trust as a conduit for Bitcoin transactions. Because Nostr is "the social layer" for a growing number of apps, trustability for any transaction can be accurately inferred without ever requiring a central authority. Only Nostr can provide such verifiable information about any pubkey, because only on Nostr can provenance be traced transparently across such a wide diversity of (voluntarily public) pubkey interactions.
And TSM is proving to be the most important NIP for Webs of Trust.
