did:x is a revolutionary new protocol that lets you pay once and own your name forever. Your did:x name then becomes a privacy-first address through which you can route messages, payments, and traffic.
Verified did:x names, strengthened by peer-to-peer key exchange and encryption, offer safety in addition to privacy unlike any other protocol.
did:x names offer an additional layer of privacy on top of payment protocols. Route incoming payments anywhere you wish as a did:x name holder.
did:x names unlock mainstream social recovery. Users can name trusted parties as “guardians” who can vote to restore key access in case of emergency.
How is this different from a web domain?
Web domains make navigating the internet easier than remembering, typing, and sharing raw IP addresses. There's a reason you type in "google.com" instead of 142.251.46.174.
But when you buy a web domain, you never really own it. You lease it, usually on a yearly basis, and if you ever stop paying for it, it is released back to the domain registrar.
Once you purchase your did:x name, you own it forever. You may re-sell it if you'd like, but no one can take it away from you if you don't want, and there are no recurring fees to remain the owner.
How is this different from ENS?
ENS, or the Ethereum Name Service, is very similar to web domains, but instead of IP addresses, ENS names are used to make Ethereum wallet addresses easier to use.
Also like web domains, you don't really own your ENS name, you simply rent it for up to 10 years at a time. If you fail to renew your ENS name, it will be released back into the pool of available names.
