I like this in general but the security section is ofuscation.

Fundimentally DHTs are vulnerable to eclipse/Sybil attacks because you can mine for/choose node IDs to compromise an arbitrary entry. You don't need to attack the entire network. Just a critical entry.

This needs a semi-centralized (ideally user configured) source of truth to fall back on to prevent attackers from just implicitly deleting critical records by filling up the DHT node-space adjacent to them and refusing to serve it.


Isn’t it similar to how Holochain operates?


I'm no expert, but it sounds similar to Holochain to me.
