A social-style feed in which every authored post is signed offline with Ed25519 and verified in the visitor's browser through Web Crypto. Security news that is relayed automatically is labelled as such and is never marked verified. All of the verification runs client-side, so it can be read in the page source.
Problem
A static host or CDN can serve modified content without the visitor noticing, so trusting the server is not a sufficient security model.
Approach
Posts are signed offline, the public key is pinned in the page, and each entry is verified in the browser. If the served key does not match the pinned one, nothing is shown as verified.
Outcome
The checkmark indicates authorship by one specific key, which an origin or DNS compromise cannot forge.
