Nostr WoT Earns a 57 Proof of Usefulness Score by Building a Portable Web of Trust Layer for the Browser

Nostr WoT is a browser extension that embeds a Web of Trust layer directly into the user’s browsing environment, enabling decentralized reputation and spam filtering across all Nostr clients. By running trust calculations locally and making them portable, it removes reliance on client-specific moderation systems. With minimal integration required, it simplifies development while giving users full control over how trust is defined and applied.
