DELIVERABLES
Business Outcomes for Your Prediction Market
Our Zero-Knowledge Oracle Proof System delivers verifiable, private data feeds that transform your market's security, efficiency, and user trust. Here are the concrete outcomes you can expect.
01
Provably Fair & Unmanipulable Markets
Every market resolution is backed by a ZK-SNARK proof, cryptographically verifying that the oracle's data is correct and was processed according to your predefined rules. This eliminates disputes and builds absolute trust with your users.

Architectural Comparison
ZK Oracle vs. Traditional Oracle for Sensitive Data
A technical breakdown of how Zero-Knowledge Oracle Proof Systems fundamentally differ from traditional oracles when handling private or regulated data, such as KYC credentials, financial records, and proprietary business logic.
| Architectural Feature | Traditional Oracle | ZK Oracle Proof System |
|---|---|---|
Data Privacy | ||
On-Chain Data Exposure | Raw data is published | Only validity proof is published |
Trust Assumption | Trusted third-party data source | Trustless cryptographic verification |
Regulatory Compliance (e.g., GDPR) | Complex, often impossible | Built-in by design |
Audit Trail & Verifiability | Opaque, relies on reputation | Fully transparent, cryptographically verifiable |
Integration Complexity for Sensitive Apps | High (requires legal & technical wrappers) | Low (privacy is native) |
Typical Latency Overhead | Low (< 1s) | Medium (proof generation 2-10s) |
Ideal Use Case | Public price feeds, weather data | Private credit scoring, institutional DeFi, healthcare data |
