5arz

5arz is a cryptographic Proof-of-Personhood layer designed to guarantee the authentic human approval behind digital interactions or human effort (Proof-of-human-work). By issuing signed credentials, 5arz provides irrefutable proof that an event was intentionally executed by a real human, moving beyond basic traffic filtering to secure the actual origin of an action.

The Limitation of Current Solutions Traditional security systems rely on probabilistic scoring to guess if a web session is legitimate. While this may filter basic automated scripts, it cannot definitively prove the human origin of high-value inputs. Simply knowing a session has human characteristics doesn't guarantee that a specific action was actively executed and authorized by a human at that exact moment.

How 5arz Works (Evidence & Reasoning):

5arz takes an affirmative, cryptographic approach to validate human presence and tie it directly to a specific output or effort:

• Comprehensive Proof of Human Action: 5arz binds a verified human to any specific event at an exact moment in time. This creates a secure, auditable trail that verifies genuine human engagement and intent behind an action.

• On-Device Liveness: Using the user's existing smartphone or browser, 5arz performs a live check to confirm a real person is physically present and actively participating. This effectively mitigates advanced automated scripts, recordings, and deepfakes.

• Strict Privacy: Biometric data never leaves the user's device. 5arz never sees, stores, or sells facial data; only a cryptographically signed attestation travels over the network.

• Independent Verification: 5arz stamps the specific event with an ES256-signed Proof-of-Human credential (a JWT). Because 5arz publishes its public keys (JWKS), developers can verify the credential using any standard JWT library in under a millisecond, without needing a proprietary SDK or trusting a central authority.

5arz acts as an open standard for human authentication. It is entirely free for individual users to generate proofs, while businesses pay for API access and verification dashboards.
