Score: 7.0/10 (Innovation: 7, Technical: 6, Documentation: 9, Utility: 6)

PEAC Protocol provides portable, signed records (receipts) for API calls, MCP tool calls, and cross-runtime interactions that can be verified offline. It's interesting because it addresses the gap between local logs and provable, boundary-crossing audit trails, enabling verifiable evidence of interactions across organizational and system boundaries.

Target audience: backend devs, devops, platform engineers
