@prologic@twtxt.net What should happen if the archive chain is detected to be broken? I don’t think that including the hash in the prev field does really help us in reality. What if messages in the archive feed themselves got lost? You can’t detect this unless you’ve already known about them. I reckon we can simply use the relative path and call it good. I know, I know, we have this format already today. But in my opinion, the hash does not add value.
