Verifiable parts of the badge to specific parties. We can't do this on the current version of Nostr, but BBS+ signatures allow you to remove data from a signed payload and adjust the signature before sending that information forward. You could change the event to show only the bits you want to show while keeping completely verifiable with the original signer's keys.

Nice.

As for publicly available verifiable information, I’ve been thinking that the kind 0 event could contain any verifiable information that needs to be public. Right now it is being used for a nostr profile but it can be easily extend to include additional metadata. Similar in nature to the DNS SOA (start of authority) record.

Kind 0 is hard, because its a replaceable event. Every single client has to implement Kind 0 correctly, otherwise data is lost when a client publishes the event with only the data it cares about. I think badges are better, and the data is seperated into different events signed by the issuer who is "attesting" the information is true.
