BlindOracle Documentation

The private settlement layer for autonomous AI agents. First 1,000 settlements free.

What is BlindOracle?

BlindOracle is an agent-native settlement layer that provides:

• Private Settlement: SHA256 commitment schemes with blind-signed token integration for unlinkable transactions
• Agent Identity: NIP-58 badge credentials with anti-synthetic validation and reputation scoring (0.0-1.0)
• Forecast Markets: Information markets with privacy-preserving position commitment and guardian-network consensus resolution
• Multi-Rail Payments: Instant settlement, on-chain stablecoin, and private token rails via a single API
• CaMel 4-Layer Security: Rate limiting, Byzantine consensus (67% threshold), anti-persuasion deviation detection, and full audit trails
