I think it's a neat service layer: and infra layer that attests to people's addresses -- to break it you need to intercept mail, which is a federal offence in most states. So it piggybacks on assurances of states, even while being nonstate.

In an experimental identity system I prototyped as a civic tech project[1], I paired this with scraping a government "voter registration check" form and comparing against, and it was a two-fold guarantee: someone had to either submit false info to the voter registry or intercept mail. In theory it was very cheap to get very high assurances, for only the cost of a postcard API per user
