## 5 个不可替代的差异

1. **AI Agent 行为 fraud-proof**：传统 L2 只有 DA fraud-proof，AxBlade 把"agent 真做了什么"也加上 challenge 机制
2. **5-层独立可验证治理**：每层独立合约组，独立升级路径，独立审计
3. **Permissionless 注册 + Trust 委托模型**：BehaviorSpec / Model / Policy 任何人可注册，consumer 选信任谁
4. **Cross-language byte-pin**：12 个 keccak literal 跨 Rust / Sol / TS 锁定
5. **Mock 透明度**：每个 mock 组件都有 swap roadmap，不掩盖

## 不与谁竞争

* **不与 Arbitrum / OP / Base 竞争 DeFi TVL**
* **不与 OpenZeppelin / Defender 竞争监管合规 SaaS**
* **不与 OpenAI / Anthropic 竞争模型 API**
* **不与 Hyperledger / Polygon ID 竞争 enterprise IAM**

主要竞争对手是**还没出现的"AI 治理 L2"**（业内目前空白）。
