Cold Root Identity v0.1.0 is live. Nostr was never meant to run long term identities off a hot private key sitting inside a mobile app. This repo ships a clean model that fixes it without changing the protocol: offline root key -> deterministic epoch keys -> signed lineage event -> clients follow rotations safely All using standard NIP-01 events and ed25519 signatures. No relay changes. No NIP changes. Just better key hygiene. Spec, docs, test vectors, and a working Python CLI are here:

If you’re a client dev, this gives you everything you need to support safe identity rotation today.

Nostr doesn’t need protocol changes for clients to stop treating the root key like a login credential. Cold Root Lineage gives users a safe, durable identity model with almost zero implementation cost.

I didn't wake up until noon. For me that is Rip Van Winkle territory. It's signal that I am burning the candle at three ends.

I'm honestly curious how many people I am going to piss off with this piece

When I meet someone for the first time I like to ask questions and get to know them. Where did they grow up? Where did they go to school? What's their pets name? What is their mother's maiden name? Then I go and hack their email.
