Our Commentary ​

This is a fascinating and genuinely important proposal from Mozilla. The bot problem is only getting worse, and current solutions often feel like they're eroding user privacy. PACT sounds like a thoughtful approach to a very hard problem. I'm always a little wary of new "credentials" systems, but the privacy-preserving aspect here is key. We need more solutions that don't just throw the baby out with the bathwater when it comes to user data.
