The opportunity

Why this matters

What our technology does

Verifies a real, unique, live human — not a bot, a duplicate, or one person running many accounts.
Issues a cryptographically signed credential (ES256) that anyone can verify offline against public keys — trusting no one.
Proof-of-Human-Fulfillment: proves a verified human did a specific task, judgment, or action — with a quality signal.
Proof-of-Human-Authorship: proves a verified human made a specific piece of content, bound to the exact file — C2PA-compatible.
On-chain personhood on Base (isVerifiedHuman) for DeFi, RWA, and agent payments.
No biometric or personal data ever leaves the device or is stored — no honeypot to breach.
Agent-native: discoverable and callable by AI via our API and MCP / OpenAPI.

Our proof-of-work system

A verified human completes work → we score and attest it → we mint a signed credential binding the human, the work, a quality signal, and a timestamp.
Verifiable by anyone against our public keys (JWKS) — no 5arz software, offline, and it fails closed.
Tamper-evident and bound to the exact work or file — copy the badge onto anything else and it fails.
Detection guesses; 5arz signs. The method is proprietary and patent-pending (US 63/979,052 + 63/979,474) — we publish what we cover, never how.

Why you need us now

Bots crossed a majority of web traffic; CAPTCHAs no longer stop AI.
AI floods every feed, dataset, and inbox — "is a real human behind this?" becomes the scarce, durable signal.
The industry named the gap: "Know Your Human." Regulators (EU AI Act human-oversight) are moving toward requiring it.
Whoever proves the human owns the trust primitive under data, content, payments, and agents.
