About
Onion sites are websites that use the .onion top-level domain and are only accessible through Tor, a decentralized anonymity network that relays traffic to hide the IP addresses of both visitors and hosts.
They have self-authenticating addresses derived from the server's cryptographic keys, provide end-to-end encryption and traffic authentication, and require no registration or approval from a central authority.
OpenID is a decentralized authentication protocol based on 
OAuth 2.0 that enables applications to verify a user's identity through an external identity provider instead of managing credentials directly.
It adds an identity layer on top of OAuth by issuing ID tokens that confirm who the user is, supports single sign-on across multiple services, and allows retrieval of basic profile information.
