TL;DR: Humanode’s Biomapper now runs on Fuse Network, giving projects a privacy-preserving, on-chain way to ensure one human = one wallet in a given context without KYC or collecting personal data. It’s fast (~15s), low cost (typically < $1), and designed for EVM dApps. Builders can add a few lines of code to keep payouts, referrals, allowlists, quests, and governance Sybil-resistant while user privacy remains intact.
What Is Humanode?
Humanode is the first crypto-biometric network built around the principle 1 human = 1 node = 1 vote. It brings Sybil resistance and human-based governance to Web3 using private, on-device facial verification without storing personally identifiable information (PII) or requiring KYC documents.
What Is Biomapper?
Biomapper is Humanode’s on-chain tool that lets one person link only one EVM address in a specific context. In practice, it stops bots and multi-account abuse at the point of verification—on-chain—while keeping user data private.
Key properties
- Fast: Accept terms → ~15-second facial liveness scan → sign a contract (small on-chain fee).
- Private by design: The video feed never leaves the device. Anonymized biometric data is encrypted locally, then checked inside a Confidential Virtual Machine (CVM).
- On-chain, EVM-native: Works with EVM chains. Developers can verify uniqueness on-chain and bridge a user’s “biomapped” status to another supported chain when needed.
- High accuracy & liveness: Reported false-accept rates of approximately 1 in 125 million for 1-to-n matching and 1 in 100 thousand for liveness checks.
Benefits of Humanode Biomapper
Fuse focuses on fast, cost-effective, high-throughput rails for real businesses and end users. That scale attracts activity yet it can also attract bots and duplicate accounts. Biomapper helps projects preserve fairness and integrity without compromising user privacy.
Benefits for Fuse users
- No KYC or forms: Verify uniqueness without sharing documents.
- Privacy preserved: Biometric data stays local; on-chain records store only the verification result.
- Simple experience: A quick scan, a single signature, and you’re done.
Benefits for builders
- Sybil-resistant programs:
- Airdrops, allowlists, quests, and referrals
- Rewards, rebates, loyalty multipliers
- Governance (one human = one vote in a given context)
- On-chain verification: Check uniqueness in contracts.
- Cross-chain portability: Bridge the “verified once” status to other EVM chains supported by Humanode.
How Biomapper Works (High Level)
- Consent & scan
The user accepts terms and completes a short liveness scan on their device. - Local encryption & private matching
The device encrypts an anonymized biometric vector. A CVM privately checks uniqueness and liveness against prior registrations. No raw images leave the device. - On-chain proof
The user signs a transaction (small fee), and the dApp can rely on on-chain uniqueness signals for that address. - Optional bridging
If needed, users can bridge their verification status to other supported EVM networks to reuse uniqueness checks across ecosystems.
Common dApp Use Cases on Fuse
Add Biomapper gates wherever Sybil resistance matters:
- Airdrops & incentives: Reward real users, not bot farms.
- Referrals & growth: Count one real referral per human.
- Governance & voting: Enforce one-person voting in a specific program.
- Quests & loyalty: Prevent multi-account farming; protect your budget.
- Access control: Gate premium features or early access by unique users.
Because verification is on-chain, you can enforce rules at the smart-contract level. Moreover, for campaigns that need pre-computed lists, Humanode also offers humancheck.app to export verified wallets you can reference off-chain.
Privacy and Security
- No PII collection: Users never upload IDs or documents.
- On-device processing: The live video feed remains local; only encrypted vectors are created.
- Confidential matching: Uniqueness and liveness checks occur inside a CVM, so raw biometrics are never exposed.
- Attack resistance: Humanode reports strong liveness detection with stringent false-accept thresholds and an unclaimed Sybil bounty maintained over multiple years.

Integration tips
- Start with a soft gate in staging (warn or flag non-verified users).
- Move to a hard gate (block rewards or access) once you validate UX and costs.
- Communicate clearly: “No KYC. No documents. ~15 seconds. Low fee.”
- For multi-program ecosystems, consider bridging the status to reuse verification across apps.
Why This Matters for the Fuse Ecosystem
Fuse is designed for B2B2C payment and consumer applications. Biomapper helps keep that experience fair and sustainable by ensuring incentives reach real people. In turn, businesses can run larger campaigns with better economics because budgets aren’t drained by automated abuse.
If you’re building on Fuse and want Sybil-resistant growth, privacy-preserving identity checks, and on-chain enforcement, Biomapper is a practical solution you can deploy today.
