shreyan - Nostr and ATProto
This post could’ve been titled “Nostr vs ATProto”, but that really isn’t what I wanted to do here. While I will be comparing and contrasting them a lot, and that’s kind of even the point of writing this, I didn’t want to really pit the two against each other at all, and especially not with the title. I also want to try avoiding commenting on the differences between the communities that have formed on the protocols and their apps, although I definitely will be looking at the philosophical differences between the two a lot - also kind of the point of writing this. This also isn’t a super deep technical post, though it assumes familiarity with technical concepts. I also might come back to edit parts of it and add more later.
