""" BTP Milestone 5.3: Cross-Tenant Autonomous Agent Marketplace & SLA Escrows ========================================================================= Provides trustless machine-to-machine (M2M) contracts between sovereign agents across distinct enterprise tenants: 1. Cross-tenant SLA Contract definition with cryptographic terms and collateral bonds. 2. Zero-Knowledge Task Completion Proofs (zk-TCP) with input/output state commitments. 3. Two-sided conditional escrow settlement via L402 Lightning sats or Base/Arbitrum USDC. 4. Autonomous agent marketplace registry with capability discovery and reputation scores.
