In Web3, trust was fragmented across wallets, platforms, and communities, which made it difficult to distinguish real participants from bots and coordinated Sybil behavior. The challenge was to design a product that could aggregate proof of humanity into one clear system while staying privacy-first and understandable for everyday users.
Step 01
A Modular Trust Layer
Designed a modular dashboard where users choose how they show they are human by collecting and verifying individual Stamps, turning scattered identity markers into one coherent trust profile.
Step 02
The Unique Humanity Score
Structured the experience around a central Unique Humanity Score built from four stamp categories: Blockchain & Crypto Networks, Government IDs, Social & Professional Platforms, and Biometric Verification. This gave users a clearer mental model for how different proofs contributed to their score and credibility.
Step 03
Transparent Verification Details
Used a sidebar-driven information architecture to make each verification step legible, with clear guidance on time, effort, cost, points gained, and whether a Stamp was verified, expired, or needed an update.
Step 04
Thresholds, Titles, and Minting
Added stronger incentive loops through score thresholds, program eligibility, activity-based titles like ETH Enthusiast and ETH Pioneer, and a final minting flow that turns reputation into an onchain asset.
The result was a privacy-first verification product that unified identity signals into a user-controlled dashboard, made trust and status easier to understand, and helped lay the foundation for Passport XYZ's evolution into Human Passport.
