As Sybil attacks and bot networks increasingly threaten onchain protocols, from token airdrops to DAO governance, developers need reliable ways to verify that wallets represent real, unique humans.

That's why we partnered with the Human.tech team to build the Human Passport Data Oracle, an open-source implementation compatible with Newton Protocol, enabling developers to verify wallet unique humanity through pre-transaction rules that apply across public blockchain ecosystems. This gives apps and agents a way to enforce humanity requirements without relying on centralized gatekeepers or manual review processes.

Bringing Humanity Verification into Newton Protocol

The Human Passport Data Oracle allows developers to bring up to three complementary verification signals into a Newton Protocol policy, where they enforce pre-transaction decisions:

  • Human Passport Stamps Score: Total points earned from user-verified credentials (Stamps) proving unique personhood
  • Human Passport Models API Score: ML-based onchain behavioral analysis that passively detects Sybil-like transaction patterns (no user action required)
  • Proof of Clean Hands: Zero-knowledge KYC and sanctions screening attestations that verify regulatory compliance

For example, a policy can require a minimum Passport Stamps score of 20, a Models API score above 50, and a Proof of Clean Hands attestation before allowing a token claim or treasury disbursement to proceed.

Because this logic lives in the policy layer rather than in smart contracts, developers can update verification thresholds and combine different humanity signals over time without redeploying contracts or rewriting application code.

What Developers Can Build With This

The Human Passport Data Oracle unlocks sophisticated anti-Sybil and compliance guardrails. For example:

Stablecoin Compliance & Growth Protection

  • Block mint/redeem transactions above thresholds for addresses without Clean Hands verification
  • Prevent Sybil farming of referral bonuses and yield rewards using Models API scoring
  • Real-time compliance gates without building custom sanctions infrastructure

RWA Bridge Compliance

  • Require a valid Proof of Clean Hands attestation before processing cross-border asset transfers
  • Meet regulatory requirements for sanctions screening while keeping enforcement decentralized and PII private

AI Agent Trading Guardrails

  • Block agent transactions if the counterparty address has a Models API score above a certain minimum
  • Protect autonomous systems from interacting with likely bot-controlled wallets without requiring agents to build custom detection logic

DAO Treasury Disbursements

  • Only execute payments above threshold amounts to addresses with both Passport score ≥ 20 AND Models score ≥ 50
  • Defense-in-depth approach catches both unverified addresses and addresses exhibiting bot-like behavior

Graduated DeFi Access

  • Tier 1 (basic): Models score ≥ 25 → standard transaction limits
  • Tier 2 (verified): Passport score ≥ 20 → elevated limits
  • Tier 3 (compliant): Clean Hands attestation → full access including RWA pools
  • Serve both crypto-native users and compliance-sensitive institutional participants with appropriate verification levels

Token Generation Events & Airdrops

  • Prevent Sybil farming by requiring Passport Stamps score minimum before token claims execute
  • No more manual review of thousands of suspicious wallets—enforcement happens automatically at the transaction layer

Composable with Other Data Oracles

Human Passport data is just one input into a Newton Protocol policy. Developers can combine it with any other Newton Protocol data oracle, such as:

  • Neynar for Farcaster identity and reputation signals
  • Veriff for additional KYC verification
  • Etherscan for gas fee and transaction pattern analysis
  • Massive for market signals and asset data
  • Magic Labs for authentication and wallet security

This composability enables developers to create nuanced policies that layer multiple verification methods to combine user-verified credentials, passive behavioral analysis, and regulatory compliance checks into a single policy execution.

Get Started

Developers can now use the Human Passport Data Oracle to bring multi-source humanity verification signals into their onchain apps. Head to the Developer Docs to learn how to integrate Human Passport data and other data oracles into a Newton Protocol policy.

The repo for the Human Passport Data Oracle implementation, including sample data and configuration files, is available here.

About Human.tech

Human Passport (part of the broader human.tech suite of products) provides the infrastructure layer for verifying unique personhood across web3, combining user-verified credentials (Human Passport Stamps), ML-based Sybil detection (Models API), and compliance-grade attestations (Proof of Clean Hands) into a unified verification framework. The platform enables developers to implement sophisticated anti-Sybil and compliance controls without sacrificing user privacy or protocol decentralization.

About Newton Protocol

Newton Protocol is the authorization layer for onchain transactions. Like a card network that checks fraud rules and verifies identity before a payment settles, Newton evaluates programmable compliance and risk policies before transactions execute, producing cryptographic attestations enforced directly in smart contracts. Built on a decentralized operator network secured through EigenLayer restaking, Newton bridges offchain compliance with onchain enforcement across RWAs, stablecoins, DeFi, and AI agent systems.
