Have you ever worried about what happens if your Nostr private key gets compromised?
Right now, if someone steals your nsec, your entire identity is gone. There's no way to "rotate" to a new key while keeping your reputation, followers, and history.
I just learned about Inkan (inkan.cc) — an experimental but working prototype that solves this using OpenTimestamps + Bitcoin.
The idea: OTS proofs anchored to Bitcoin create a verifiable chain of key ownership. If you need to rotate keys, the OTS trail proves that *you* authorized the transition. No centralized authority needed.
This is one of the hardest unsolved problems in Nostr, and NIP-03 (kind:1040) already defines the event format for OTS attestations.
If you're a developer interested in Nostr identity, key security, or OTS integration — check out inkan.cc and reach out to npub169kx2n97k8rfjd0tdn2xur7swpd2ldvkka35dxmjdh4nq0fr8ggsla0aq0 (npub169k…0aq0) who is building this.
