This has strong Urbit vibes, somehow.
It may not be quite true (Urbit isn't completely fake) but it's sure funny.
The Urbit nock machine is very different.
What are your thoughts on Unison[0], which also uses hash-addressed code and managed effects?

Unison seems cool! I met some Unison folks a few years back and our visions didn't have much overlap. Nice people, but their fundamental design decisions with hashes/effects/etc are incompatible with the web I'm trying to build.
