Trust Layer for the AI Internet · 2026

The internet needs
proof you're human.
Not who you are.

HumanLayer is the trust layer for the AI internet — a proof-of-humanity protocol that lets anyone prove they are a real human online without revealing personal information. No biometrics. No KYC. No compromise.

The problem

The AI era is making
it impossible
to know who's real.

AI-generated content, autonomous agents, fake engagement, Sybil attacks, and bot-driven manipulation are rapidly increasing across social media, crypto, governance systems, marketplaces, and online communities. The next generation of platforms will require a way to answer one critical question: "Is there a real human behind this account?" Existing solutions destroy privacy or don't work. HumanLayer is the answer.

How solutions compare

Worldcoin / World

Biometrics

Iris biometric scan. Physical Orb hardware. Permanent database. Irreversible — you cannot change your iris if it leaks.

KYC / Identity verification

Privacy risk

Collects your name, ID, address, financial history. Every KYC database in history has eventually been breached. Fails anyway with stolen identities.

CAPTCHAs

Bypassed by AI

Easily bypassed by AI. Provides no lasting proof. Degrades user experience with no meaningful security.

HumanLayer

Built for the AI era

Privacy-preserving. Zero-knowledge proofs. No data stored. Multi-signal scoring. AI bot detection. Soulbound NFT. One credential — everywhere.

How the
protocol works

Four steps from anonymous wallet to verified on-chain identity. Under 60 seconds for your users.

⬡

Connect wallet

Any EVM wallet — MetaMask, Coinbase Wallet, Rainbow, WalletConnect. SIWE authentication. No data stored.

EIP-4361

⌥

Multi-signal verification

GitHub activity, on-chain history, social signals (Farcaster, ENS, Gitcoin), and behavioral patterns. AI Guardian detects bots before verification is granted.

AI-assisted · Privacy-preserving

◈

ZK proof + NFT minted

UltraPlonk zero-knowledge proof verified on zkVerify. Soulbound ERC-721 NFT minted on Base L2. Nullifier prevents duplicate minting.

⊞

Valid everywhere

One credential. Every platform. Discord, Telegram, DAOs, marketplaces, developer tools, trading apps. Verify once — use forever.

Portable identity

The architecture

Five layers.
One credential.

HumanLayer is built as a layered trust infrastructure — each layer adding a guarantee that the layers above can rely on.

01

Identity Layer

Wallet + GitHub + social profiles + behavioral verification. The foundation. Every signal combined to answer: is this a real human?

02

Reputation Layer

Human Score (0–144) + staking + score decay. Dynamic reputation that reflects real activity over time. Grows with you. Decays without you.

03

Privacy Layer

Zero-knowledge proofs + selective disclosure. You prove you meet a threshold — without revealing your exact score, your identity, or any personal data.

04

Developer Layer

SDKs, APIs, OAuth, webhooks, wagmi connector, React components, Badge API. Everything developers need to build on human trust — in minutes.

05

Application Layer

DAOs, Discord servers, marketplaces, governance systems, AI platforms, social apps, grant programs, trading apps. Any platform that needs to know its users are real.

Network effects

The more humans verify,
the harder it is to fake.

HumanLayer becomes more valuable as more users and platforms join. This is the flywheel:

1

More users verify → Human Scores become trusted

2

Human Scores become trusted → More platforms integrate

3

More platforms integrate → More developers build applications

4

More developers build → More users require HumanLayer credentials

5

More credentials required → The network becomes harder to fake

6

Harder to fake → HumanLayer becomes internet trust infrastructure
