Verification Sources
Select one or more providers to verify your humanity. Each verification awards 1 trust score token.
Worldcoin
Biometric iris scan with zero-knowledge proof
Gitcoin
Reputation score based on verified credentials
Proof of Humanity
Video submission with community validation
BrightID
Social connection verification network
Binance
Centralized exchange identity verification
The Global Problem
The internet is drowning in bots. Every Web3 game, airdrop, and DAO faces the same issue — Sybil attacks.
- $1B+ in rewards are stolen by bots each year.
- 60–90% of airdrop participants aren’t real humans.
- Developers integrate multiple fragmented verification systems.
- Users are forced to re-verify in every app.
- No single, trusted standard for Web3 identity.
Our Mission
To make proof of humanity as easy to integrate as payments. We unify major verification providers into a single standard API so builders focus on shipping and users stay verified everywhere.
One Integration → Global Verification
Connect once. Access Worldcoin, Gitcoin Passport, Proof of Humanity, BrightID and more. HumanityOracle caches verified status on-chain for interoperable checks across protocols.
Our Product
Unified API
One endpoint for all major PoH sources with normalized responses.
On-chain Cache
Query verified human status on-chain for transparency and composability.
Open SDKs
Solidity, TypeScript, and Python SDKs for rapid integration.
Privacy-Preserving
Privacy-first and zero-knowledge ready. No personal data stored.
Scalable
Built for high-throughput checks with minimal setup.
Interoperable
Works across chains and protocols via a standard interface.
Advanced Features
Mathematically sound sybil resistance with adaptive learning
Bayesian Aggregation
Probability of "human" calculated from multiple independent sources using Bayes' theorem:
Each source contributes independently, increasing confidence exponentially.
Attack Detection
Automatic detection of suspicious patterns:
- Rapid verification bursts
- Low quality score patterns
- Anomalous behavior detection
Real-time monitoring with on-chain event emission.
Adaptive Updates
Source confidence scores update automatically when attacks are confirmed:
Self-improving system that learns from confirmed attacks.
How It Works
Users verify via any supported provider. HumanityOracle aggregates and normalizes proofs. A unified Humanity Score or Verified Human status is stored on-chain. Apps call our API to check humanity instantly.
Verify
User completes verification with Worldcoin, Gitcoin Passport, PoH, BrightID, or others.
Aggregate
We aggregate and normalize proofs into a single, consistent format.
Cache on-chain
We write a verified status or score on-chain for transparent, interoperable checks.
Integrate
Apps call one API or use our SDKs to perform instant humanity checks.
For Developers
Stop integrating five APIs. Integrate once and ship faster.
For Users
One verification, infinite access. Keep control over your privacy.
For the Ecosystem
Reduce Sybil attacks, increase trust, and unlock fair incentives.
Frequently Asked Questions
Is HumanityOracle another verification provider?
No. We’re an aggregator that connects and unifies existing proof systems.
Do users need to verify again?
No. If a user is verified via Worldcoin, Gitcoin, or PoH, they’re already human in our system.
How do developers integrate?
Through a single API and SDKs for Solidity, TypeScript, and Python.
Is the data stored on-chain?
Yes. We cache verification status on-chain for transparency and interoperability.
What about privacy?
We never store personal data. Privacy-first and zero-knowledge compatible by design.
