Idena Stamp (Retired)

This stamp has been retired. The Idena Stamp was retired as part of the January 2026 reweight and is no longer available for verification or scoring.

The Idena Stamp previously allowed users to prove their humanity through Idena’s “Proof of Person” — synchronous validation ceremonies in which participants solve bot-resistant puzzles. Connecting an Idena account to Passport verified the user as a genuine individual.
