What would quantum-safe Nostr look like?
Nostr is actually well-positioned for post-quantum migration:
Possible approaches:
* New NIP for PQC keys
* * Dilithium
* * Falcon
* * SPHINCS+
* Dual-key identities
* * Classical key (secp256k1)
* * PQC key (for forward security)
* Identity rotation
* *Old pubkey signs new PQC pubkey
* Relays enforcing PQC-only events

Thanks MK Fain (nprofile…kt58) for making me look into Nostr's quantum resistance and turning my shitpost into a little bit of knowledge and exploration.
I am far from an expert in cryptography, so this could all be bullshit.
