    I've been working on a project for the last six months that brings mTLS to the masses. Meaning, post-quantum end-to-end encryption with human readable identities. It uses a decentralized root of trust for, basically, a lot of the history this article covers.

      Human readable identities are the hardest part (unless you just mean BIP-style word chains). What’s your approach look like? How do you prevent collisions?

        You register a DNS-style name. Registrations lasts a year with a 3 month post-expiration window to reregister, otherwise it gets released back. The system goes out of its way to make name trading uneconomical - specifically to work against speculators and name-sitters from coming in and ruining things.

          I wonder if something like this could follow the spirit of &quot;tag&quot; URIs where you include a temporal component. A semantics of &quot;namespace Foo as established time T.&quot;<p>Any usage of the name in identifiers includes the epoch. Identifiers from several epochs could be concurrently in use. Identifiers rooted in different name epochs are not be comparable.<p>Out of band networking effects need to establish the meaning of a specific name epoch. The disambiguation doesn&#x27;t work if the intended consumers are unwilling to learn and distinguish the epoch component of identifiers they care about.<p>I suppose, at the limit, this is the same as just having everyone add some numeric suffix to names they try to register? But it would be more constrained, e.g. structurally enforce that the digits correspond to some kind of clock metadata which is a witnessed and signed part of the decentralized ledger.

          Ah, ok. Is there a fallback for using bare keys instead of human readable names? If not, you have just recreated a central gatekeeper problem; you could be ordered to terminate name service for someone. Unless it’s using some decentralized crypto system like eth.<p><i>Optional</i> human readable names could be a good system combining convenience with resilience.

            It&#x27;s using a decentralized backend. No, it&#x27;s not using any existing blockchain, nor does it have any tradable token. It does have some blockchain properties, but the main layer is built on top of libp2p.<p>Agreed it&#x27;s a very hard problem. We&#x27;re in the process of forming a syndicate of like-minded parties who are interested in seeing this come to life because the model itself has no exit plan and is basically anathema to traditional capital funding.<p>Also, to be clear, names are hashed&#x2F;salted in the backend with Argon2ID and a rotating salt. So the name index itself isn&#x27;t enumerable, but it doesn&#x27;t necessarily guarantee names are private once they are shared publicly. Theoretically you could lookup someone based on their public key without knowing their name - so in that sense it&#x27;s somewhat close to what you&#x27;re describing.

              Interesting. Yes, the possibility of direct key lookup would solve the problem, especially if existing contacts remain connected even after name expiration&#x2F;revocation.<p>Perhaps you could do a name presale, although I’m not sure that would be enough funding. I look forward to hearing more about it.

                We&#x27;ll probably do a name presale, but this is deep tech&#x2F;big infra we&#x27;re setting up, so it wouldn&#x27;t be enough. That&#x27;s why we&#x27;re busy partnering with like-minded individuals to do a non-traditional raise. We did start with the more traditional route, but all of them (including a16z) were baffled by our choice to not resort to degenerate behavior (i.e. a16z in particular refused to play game without making a token and listing it on a DEX).<p>Anyone interested can reach me directly at hn@sepositus.com (this is a SimpleLogin alias to protect my email from spam).

    Coauthor here, somewhat surprised to see this on HN. Any thoughts, questions, or feedback welcome.

      Thanks for putting this together. Found via Schneier’s blog; I thought it was a good summary, and perhaps needed information in the face of attacks like Chat Control.

    “Everything is end-to-end encrypted… depending on how you define the ends.”

      It is not great that they use the E2EE term to describe TLS, although it&#x27;s for a good cause
