DNS has always been decentralized. I mean, first sentence on wikipedia:
> The Domain Name System (DNS) is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network.
> The Domain Name System (DNS) is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network.
> While DNS is already fairly decentralized, the centralization exists because of ICANN’s gatekeeper control .... ICANN ultimately has control over what internet names are acceptable – and serves as a singular point of failure.
That is what this is doing.
> Handshake is a decentralized, permissionless naming protocol compatible with DNS where every peer is validating and in charge of managing the root zone with the goal of creating an alternative to existing Certificate Authorities. Its purpose is not to replace the DNS protocol, but to replace the root zone file and the root servers with a public commons.
