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

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

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 ?

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

ActivityPub can be used for both public and private messaging, though I don't think the e-mail standard needs to be retired anytime soon.

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

ActivityPub is embraced by:

  - Threads  
  - Flipboard  
  - WordPress  
  - micro.blog  
  - NodeBB  
  - PeerTube  
  - Pixelfed  
  - GoToSocial  
  - Akkoma  
  - ...and countless smaller projects

It is by no means just Mastodon.

see my comment in another thread, things are happening!

What sorts of things can be built on the protocol?
