Agree that small worlds are where it's at these days.
This is unrelated but before you mentioned an idea about urbit names on Bitcoin as an alternative to that new Spaces deal, maybe pointing to Pkarr. Sounded interesting, did you manage to thresh that out? Also Fiatjaf's rationale for a spacechain to keep things in Bitcoin-land without a competing altcoin made some sense to me, but no idea if that angle has been showing progress these days or not.
My idea was simple, basically put your pkarr in an OP_RETURN and use the order of the utxo since genesis block as the ID.
It works, and because it is immutable there is no need to spam Bitcoin to get good names.
But I generally believe we should assume that Bitcoin data will be pruned. And stop pretending that it is a database.
Yes realistically speaking someone will always have an archive of all OP_RETURNs, but there won't be many, and if anything we might be at peak number of archival nodes.
So just from a principal point of view I gave up on this idea.
Spacechain doesn't change this dynamic (I do support spacechains to hopefully extend Bitcoin with smarter opcodes), you can't just pretend that data will be available by lots of people forever... this doesn't scale so any blockchain that doesn't invest in being prune friendly will die, aka be pruned entirely.
Data availability forever for free for many people is just never going to work.
Orgs should keep using ICANN, and fight for it's integrity because seriously it is the best that can happen.
