On-chain Proof-of-Humanness
Keywave transforms human voice into a multi-dimensional identity proof, anchored on-chain for a private and sybil-resistant Web3.
Proof-of-Humanness (PoH)
Keywave verifies human voice—not a device or username—to create a private, tamper-resistant identity signal. Each verification transforms a voice sample into a privacy-preserving hash and anchors it on-chain.
Step 1
Capture Human Voice
User speaks a short phrase. Audio is processed locally or server-side; raw audio is never stored long-term.
Step 2
Hash & Anchor On-Chain
We derive a privacy-preserving embedding → hash and anchor it on-chain, producing a tamper-evident record.
Step 3
Verify & Trust
Apps call Keywave to verify a probe sample against a user’s anchored identity signal—Sybil resistance without storing biometrics.
