PEAC Protocol: Signed interaction receipts

PEAC Protocol provides a framework for generating signed, portable interaction receipts for actions performed by automated systems such as AI agents, MCP tools, APIs, and gateways. It enables organizations and developers to record and later verify system actions, decisions, and events across boundaries, providing cryptographically signed evidence for audit, dispute, compliance, or operational workflows. Its focus on verifiable records enhances trust, accountability, and transparency in automated workflows.
