Reputation no one can see.
Authority anyone can verify.
Five primitives composed into one replayable attestation: biometric anti-sybil, encrypted activity, FHE-aggregated score, selective ZK disclosure (prove rep ≥ X without revealing the score), and post-quantum receipts that any third party can independently replay offline. This page runs real cryptographic verification in your browser.
One human. One reputation.
H33 hashes a fresh device-bound credential into a 32-byte enrollment commitment. The credential never leaves the device; only the commitment is observable. In production this commitment is bound to a platform authenticator (Face ID, Touch ID, Windows Hello, or hardware security key); this demo uses a deterministic per-session credential to exercise the same SHA3-256 primitive in WASM.
Every event becomes a private receipt.
Each DAO event (vote, proposal, contribution, attendance) is encrypted at the source and gets its own H33-74 receipt: 32 bytes of canonical commitment + 42 bytes of post-quantum signature material. The raw event content is never observable; only the receipt commitment is.
The server runs the math. It cannot read it.
The server combines your encrypted contributions under Fully Homomorphic Encryption (BFV / CKKS). It never decrypts. The output is an encrypted score envelope — a ciphertext only you (or a ZK proof) can interpret.
Prove your rep clears a threshold. Reveal nothing else.
Set a threshold X. The server emits a ZK-STARK proof that your encrypted score satisfies rep ≥ X. The proof is verified in your browser with no further server contact — and reveals nothing about the actual score, contribution history, or the operations that produced it.
Same bytes. No operator. No trust.
Download the replay bundle and verify it offline. The h33-verifier (Apache-2.0, public on GitHub) reconstructs the entire reputation lineage from the bytes alone. No call to H33 required. This is what makes the score independently auditable by a DAO, a regulator, or your customer's forensic team — without trusting us.
