@jupiter_rowland@hello After a cursory investigation, I get the impression that nomadic identity is in its infancy:
it seems to be tied to Hubzilla and (streams)
it doesn't seem to have a spec
it seems to be implemented only in PHP
I'm happy to be corrected!
It's hard to know whether nomadic identiy is a tiny niche thing that'll stay that way or something that's going to be huge. Of course, I hope for the latter.
