One use case that's already operational and doesn't need additional transactions - distributed domain resolution The entire .eth registar runs in a smart contract. You put your ETH in to claim the domain, others also bid during the bidding period, the winners ETH is locked away and returned when they release the domain, the rest get refunded. Considering DNS is continually politicized and still subject to points of failure (the CAs), distributed ENS is a far better design IMO
