How it works
Oracle in Action
From s402 authorization to on-chain settlement—powered by autonomous AI agents and cryptographic verification.
s402 Payment Authorization
Agent creates HTTP 402 payment authorization with EIP-2612 permit. MultiWalletS402Pool selects worker wallet for parallel processing without nonce collision.
Dynamic Source Discovery
AI agent decomposes query into sub-queries via LLM reasoning. Semantic search identifies ephemeral APIs, TLS verification ensures authenticity, SHA-256 hashes stored on IPFS.
Multi-Source Consensus
Agent cross-verifies data from multiple sources with 80% agreement threshold. Ensemble methods resolve conflicts. EIP-712 cryptographic relays ensure dispute efficiency.
On-Chain Settlement
S402Facilitator verifies Merkle proof and settles payment (1% fee). Agent relays resolution on-chain with cryptographic proof. Markets settle instantly with verifiable integrity.
Why Sora Oracle
Agentic Paradigm Shift for Oracles
Autonomous AI agents. Micropayment protocol. Self-expanding network.
s402 micropayments enable frictionless agent-tool interactions on BNB Chain
10x parallel speedup with MultiWalletS402Pool (500 queries/second)
AI-powered permissionless oracle with dynamic API discovery
Self-expanding research agents with cryptographic verification
Multi-source consensus (80% threshold) eliminates single-source errors
84.9% gas savings vs traditional oracles with batch operations
Core Capabilities
Agentic Oracle Infrastructure
AI-powered permissionless resolution with s402 micropayments. Self-expanding agents deliver human-surpassing speed and accuracy.
s402 Micropayment Protocol
HTTP 402 integration with EIP-2612 permits and Merkle proof verification. Truly frictionless micropayments on BNB Chain.
10x Parallel Speedup
MultiWalletS402Pool with 10 worker wallets achieves 500 queries/second, solving EIP-2612 sequential nonce limitation.
Agentic Resolution Network
Autonomous AI agents with LLM reasoning decompose queries and synthesize multi-modal data for adaptive resolution.
Permissionless Oracle
AI-powered API discovery with TLS verification, SHA-256 hashing, and IPFS proof storage. No centralized gatekeepers.
Cryptographic Security
EIP-712 structured data prevents malleability. ZK proofs enable private queries for sensitive markets.
BNB Chain Integration
3-second blocks and opBNB L2 scaling enable real-time resolutions with 84.9% gas savings vs traditional oracles.
Self-Expanding Network
High-performing agents fork and register variants in s402 Scan Marketplace—evolution through natural selection.
Multi-Source Consensus
Agents cross-verify with 80% agreement threshold. Ensemble methods resolve conflicts for robust accuracy.
Real-Time Settlement
Instant on-chain settlement with automated verification. Unlike Ethereum's congestion or UMA's 48-hour disputes.
