If you are interested in building on ATProtocol, one of the best places to start is the Discord (until we have an atproto native alt @blebbit.app)

https://discord.atprotocol.dev/

Of course the spec is good too, very easy read

https://atproto.com

https://docs.bsky.app

What sorts of things can be built on the protocol?

ATProto is a lot of fun to work with, but of course by no means perfect. The biggest challenge right now is dealing with private data, I hope they can figure out a way to support it soon.

If you want to find other apps that are using Bluesky and ATProto we run https://blueskydirectory.com for that. Feel free to add any apps you find to it!

In this house, we believe “AT protocol” refers to Hayes modem commands.

Would be great to have a new modern alternative to the E-mail standard that is usable for both public and private messaging.

We might be able to do this with permissioned spaces. There are instances or use-cases where you want an outside entity to make changes to a user's repo

- email / inbox [or @mail since it is @atproto :]

- unsubscribe from email

- notifications / rsvp

The cool thing is that we could use the stackable moderation infra for dealing with bad actors

email has come a long way with SPF, DKIM, and DMARC, and its cool that anyone can purchase a slice of the global namespace that is transferable between providers, but AFAIK the biggest road block to using email in a distributed self sovereign way is reputation and getting your messages delivered to google and outlook users partially because of the nonstop spam.

Do we have any new tools to prevent spam in a post-email world? Or can we just use the current email structure with some better GUI around PGP and Hashcash and force anyone who wants to send a message to burn 10 cents worth of electricity ?

I'm curious what you're looking for in an email standard ?

Been pondering for my team to use it for our product’s timeline. I don’t particularly want our user base to be Bluesky, but it’d be good to have support for the protocol, and control over the system.

Have there been any products go embraced this? Or is it like ActivityPub where basically the whole thing is Mastodon.

For now mostly just small things that the Bluesky dev/user community is playing with, but check out e.g. Tangled which is meant to be a GitHub alternative on ATProto: https://tangled.sh

And here is an app to generate unified feed for such apps: https://bsky.app/profile/atpage.one

Would love for more platforms to embrace the AT protocol.

I'm working with some people on permissioned spaces for atproto (spec and pds changes). This will unlock a ton of use-cases not possible today

Working Group is forming this fall, we'll be at IETF, Montreal in Nov

Also building one such platform that needs permissioned spaces, if you want to follow along

https://github.com/blebbit/atproto

https://bsky.app/profile/blebbit.app

Off the top of my head, there are also WGs for E2EE messaging, web monetization, and geo.

Lot's of infra getting built this year

I'll save you a click: it's unrelated to the Hayes AT commands [1].
