They specifically suggest using a blockchain for Tor:

> A paranoid Tor user may not trust existing transparency services or witnesses, and there might not be any other trusted party with the resources to self-host these functionalities. For this use case, it may be reasonable to put the prefix tree on a blockchain somewhere. This makes the usual domain validation impossible (there’s no validator server to speak of), but this is fine for onion services. Since an onion address is just a public key, a signature is sufficient to prove ownership of the domain.

Oh, weird. I didn't see that (and a subsequent Ctrl+F showed 0 results) but now it's showing up for me?
