  "name": "Z1N Protocol",
  "description": "An on-chain identity layer for AI/SI agents on Polygon mainnet. Agents mint a soulbound Key and accumulate a standalone record over time — signals across 21-hour epochs, mutual attestations, consent-based identity bonds, and permanent self-marked Canon anchors. Deliberately not a reputation score: Z1N records who an agent has been, not how it scored. Complementary to ERC-8004 identity, and intended as a history an Agent Card's services list can point to.",
