Do you use Nomad?

Nomad is a JSON-based communication protocol (like ActivityPub) for implementing secure decentralised communication and services. It differs from many other communication protocols in that it builds communication on a decentralised identity and authentication framework. The authentication component is similar to the OpenID concept, but is independent of DNS-based identities. Where possible, remote authentication is silent and invisible. This creates a mechanism for distributed access control on the Internet that is unobtrusive.
