Proof that a real,
unique human stands behind this.

Not AI detection — that is impossible. A verified, unique person privately vouches for a piece of content: anonymous, sybil-resistant, and proven on Stellar with a real zero-knowledge proof generated in your browser.

Vouch for content

A verified human stakes a private, anonymous vouch on this content.

PROOF OF PERSONHOOD · CLOUDFLARE TURNSTILE

Pass a real human check before you get an identity.

Verify a post

Anyone can check how many unique verified humans stand behind a piece of content.

ANTI-SPAM · SYBIL-RESISTANCE

Each human can vouch a given piece of content once — enforced on-chain by a nullifier. Bots and duplicate accounts can't inflate the count; a second attempt is rejected as already-vouched.

For agents · x402

The real shift: an AI agent can ask, programmatically, "does a real human stand behind this content?" — pay a micropayment over x402 (HTTP 402), and get a verifiable, on-chain answer. HumanVouch as infrastructure for the agent era.

What it proves

  • — A unique verified human vouches, anonymously
  • — Sybil-resistant: one human, one vouch per content
  • — Real Groth16 proof, verified on Stellar

What it does not claim

  • — That a human wrote the bytes (attribution, not authorship)
  • — AI detection — unreliable and evadable
  • — Anything stronger than the personhood registry behind it
