• Is the content coming from a trusted source?

• How does the publisher ensure the quality of the updates?

Increasing your product reach The Salmon Protocol: Things to Consider

1. Subscriber sends signed request to publisher (e.g. using acct:johndoe@subscriber.example.com).

2. Publisher performs discovery on endpoint to verify identity provider.

• Webfinger• LRDD (Link-based Resource Descriptor)

3. Provider verifies signature via public keys obtained during discovery.
