We've built a social registry, using Github login, where you can host your Signature Agent card/JWKS over a dedicated link. This saves you buying a domain and self-hosting your card. Please try it out : https://openbotauth.org/login
We've also built a Wordpress plugin, which works in signed and unsigned mode. Unsigned mode gives you a preview and Signed mode gives you all access. Websites can point their origin server to our registry or use other registries to block unverified traffic.

The next step is to build the delegation as discussed here: https://thibmeu.github.io/http-message-signatures-directory/...
We'd love your feedback on our social registry and how we can improve it. :)
