Is Bridgy Fed a PDS?

[singpolyma]

I'm curious about how this is implemented architecture-wise on the bluesky side. Does Bridgy Fed effectively act as a PDS and then the network gets the content that way, or is there another approach being taken?

Hi @singpolyma! Good to see you here! Yes, BF is effectively a PDS. It stores repos and serves their contents over subscribeRepos, getBlocks, getRecord etc to the Bluesky relay and anyone else, and it's in bridged users' DID docs in the service section, eg https://web.plc.directory/did/did:plc:2xgjhj6jge6kgj73szlasuno :

  "service": [
    {
      "id": "#atproto_pds",
      "serviceEndpoint": "https://atproto.brid.gy",
      "type": "AtprotoPersonalDataServer"
    }
  ],

Nice! Using plc dids for now even for bridged websites I guess? Path of least resistance less setup for users.

It also (theoretically, eventually) should allow keeping the account if the domain has to be replaced with another for some reason.
