Stamp Re-weight: January 2026
Human Passport implemented a reweighting of its verification stamps in January 2026 to strengthen humanity verification signals. The update addresses an evolving landscape where Sybils learn the rhythm and automation increasingly mimics human behavior.
Core Philosophy
The system maintains dual principles:
- Make verification simple for real humans to participate
- Make it difficult for automation to blend in
New Stamps
Steam Stamp (Beta)
- Free verification
- Worth 2.8 points
- Leverages gaming history as a difficult-to-fabricate, globally distributed humanity signal
Point Value Changes
| Stamp | Previous | New | Status |
|---|---|---|---|
| Discord | 0.516 | 2.8 | Updated (Beta) |
| Biometrics | 5 | 6 | Graduated from Beta |
| Proof of Clean Hands | 1 | 3 | Reweighted |
| Guild | varies | 0.468 | Adjusted |
Retired Stamps
- Idena and BrightID have been removed due to low activity and verification issues.
- Existing verified stamps remain valid until expiration (90 days).
- Retired stamps cannot be renewed after retirement.
Implementation Details
The rollout protects existing users: if you already hold affected Stamps, you keep your current points until those Stamps expire. Score fluctuations occur only upon expiration, not immediately.
