# Halo2 + EZKL zkML

## 现状

* **MockHalo2Verifier**: chain 391 上的 mock，接受任何 proof（PoC）
* **真 EZKL Halo2 swap**: 6 周 roadmap

## EZKL 路线图（已写好）

| Week  | 任务                                 |
| ----- | ---------------------------------- |
| W1    | 环境 + ezkl install + MNIST baseline |
| W2    | MNIST CNN ONNX → Halo2 circuit     |
| W3    | KZG SRS + verifier deploy          |
| W4    | 端到端 prove → verify                 |
| W5-6  | MNIST 完整 e2e                       |
| W6-7  | CSDRT logistic regression          |
| W8-10 | 性能优化 + audit prep                  |

**预算**: \~25 工程师天 + \~$0.0024/proof 主网估算

## 性能 vs Groth16

| 指标           | Groth16              | Halo2         |
| ------------ | -------------------- | ------------- |
| Proof size   | \~256 bytes          | \~few KB      |
| Verify gas   | \~250K               | \~600K        |
| Setup        | per-circuit ceremony | universal SRS |
| Proving time | 较快                   | 较慢但 universal |

主网 zkML 选 Halo2 因 universal setup 适合多模型场景。
