AT Protocol/Bluesky

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.
