Verifiable AI Oracle powered by Nautilus TEE
Walmarket combines GPT-5, Nautilus TEE, and cryptographic proofs to create the world's first truly verifiable AI oracle:
🔐 TEE Execution
AI inference runs inside Nautilus secure enclaves with cryptographic attestation
🔍 Multi-Source Verification
Cross-reference multiple trusted data sources for accurate outcomes
📊 Transparent Reasoning
Complete evidence bundle stored on Walrus for full auditability
⚡ On-Chain Verification
SUI smart contracts verify TEE attestation and aggregate verified reports
The only prediction market oracle that proves AI execution integrity through trusted hardware - no trust required.
Nautilus TEE
Trusted Execution Environment ensures AI inference cannot be tampered with, providing cryptographic proof of execution.
SUI Blockchain
High-performance Layer 1 with Move smart contracts for secure, efficient market resolution and aggregation.
Walrus Storage
Decentralized storage for permanent, immutable evidence bundles with cryptographic integrity guarantees.
Built for Walrus Haulout Hackathon 2025
Walmarket is a submission for the Provably Authentic track, creating a verifiable truth engine through prediction markets. By combining SUI, Walrus storage, Nautilus TEE, and GPT-5, we deliver:
- ✓ Verifiable AI Oracle - TEE-powered GPT-5 inference with cryptographic attestation
- ✓ Immutable Evidence Storage - Complete audit trail on Walrus with blob hash verification
- ✓ On-Chain Verification - SUI smart contracts validate TEE signatures and aggregate reports
- ✓ Economic Truth Incentives - Stake, slash, and reward mechanisms for accuracy
- ✓ Trustless Resolution - No operator trust required thanks to secure hardware proofs
Prediction markets are proven to be more accurate than polls and expert opinions. Walmarket brings this power to Web3 with verifiable AI execution, creating unstoppable truth infrastructure.
