We aren’t too concerned with billionaires cosplaying as altruists and the technologies they produce, but the AT Protocol has a few ideas, particularly related to identity, that are interesting.
Specifically, AT protocol differentiates between handles and identities, where DNS entries are used as short handles that resolve to a DID.
That’s about it, the rest of the handling of DID’s is extremely centralized (see did:plc which requires resolution against a single domain), and the requirement of all posts to be funneled through Big Graph Services rather than directly peer to peer is transparently designed to ensure a marketing and advertising layer in between actors in the network.
Lexicons were based on RDF?
Using Domains as identity is great! the PLC method is not so great! We should use domains as a way of bootstrapping nodes into the network, giving people some extrinsic means of discovering the active peers within their identity, and also a means of distributed bootstrapping into the network.
