It’s fairly easy to understand but you won’t really see it and that by design. The point is to make the underpinning so seamless that it feels like a centralized app. The proof of concept is Bluesky, but if you would like to see other services that are completely unaffiliated with Bluesky PBC than check out:
- whtwnd.com (Whitewind)
- A longform blogging platform that has its own Lexicon and AppView
- pinksea.art (Pinksea)
- An oekaki BBS with its own lexicon and CDN implementation
- tangled.sh (Tangled)
- A git forge integrated with atproto, they even have made some additions with regards to knots.
All of these and many more are being built along with infrasstucture plays from the like of Blacksky, Northsky, and Free our Feeds.
That’s because its new. ActivityPub has been around for 7 years now, and I’d argue its totally stagnated on Mastodon to the point that the fediverse is mastodon to most people, and the norms of message passing are ruled by mastodon. Whereas atproto has been around for 2 years, one of which was in a very small and restricted alpha stage to get the core blocks stable. Now we see so many projects getting off the ground, some of the ones I mentioned being the most mature. With that said they are all earlydays, as is the protocol.
If we really want to talk about massive leaps, and a vibrant dev community thats actively build and expanding the protocol even faster than atproto, than its Nostr. Problem with them is the community building it 😅
