      or an easy way to generate a new key every day or so and automatically propagate it out through my social network?

      I think you need a blockchain-like thing to publicly announce key rotations.

      Signing your new key with your old key + gossip protocol is enough. No need for common ledger. I want a social substrate anyway.

      I think you want some sort of concrete record about the key changeover, putting it certifiably in the past.

      …so that if a past key is compromised, an attacker can’t just publish “I’m using this new key, X now!”

      who should participate in the block chain? I want to avoid creating a single authority on identity.

      good question. Gossip might also work. Basically there needs to be a semi-public way to detect when attacker tries to publish a key

      so a credible way to say "Peter has been using this key for years" is valuable.

      I think the solution for public entities like brands is fundamentally different from social interaction

      and this delineation is orthogonal to the medium of communication

          I don't think I follow that assertion. I'm solvin for the case: "I want to send a message to Peter. I look up a public 🔑 for him…"
