SE Radio 651: Paul Frazee on Bluesky and the AT Protocol

Paul Frazee, CTO of Bluesky,
speaks with SE Radio's Jeremy Jung about the Authenticated
Transfer Protocol (ATProto) used by the Bluesky decentralized
social network. They discuss why ATProto was created, as well as
how it differs from the ActivityPub open standard, the scaling
limitations of peer-to-peer solutions, cryptographic
decentralized identifiers, and creating a protocol based on
experience with distributed systems. They also examine the role
of personal data servers, relays, and app views, the benefits of
using domain names, allowing users to create algorithmic feeds
and moderation tools, and the challenges of content moderation.
