There's a blockchain project that attempts to decentralize TLDs - people would actually own their TLDs (by cryptography!), and would issue their own certificates. Only you and no one else would be able to issue a certificate for your TLD. I've been shilling for this project enough, and feel it's a little offtopic here, but if you're really interested you can find it in my recent post history :)
