ecideConsensus` first-wins: 每 oracle 取第一票

## 3.7 evidence_hash 占位

投票 chain_event 含 evidence_hash 字段, v0.5 是**非功能 placeholder** (= 没有验证价值). 真验证机制留 Area 9 dispute resolution.

## 3.8 投票 ≠ 签 settle TX (= 关键边界)

| 动作 | area | 内容 |
|---|---|---|
| **投票** | area 3 | oracle 上链 chain_event 说 "我认为是 X". decideConsensus 用来定 winner |
| **签 settle TX** | area 4 | oracle 用 PK 签真正花钱的那笔 multisig TX. 签的是 `blake2b(market_id \|\| winner \|\| pools \|\| merkleRoot \|\| metadataHash)` |

**投票 = 嘴上说; 签 TX = 真盖章**. area 3/4 边界画清.

## 3.9 V8 — Herd voting 防御 (= Owner 钦定 双轨路径)

### 问题
投票是 chain_event 公开可见. oracle 1 先投 YES → oracle 2 看到 → 抄 oracle 1 而非独立判断 = herd voting = 破坏 truth-seeking.

### Owner 钦定: A v0.5 + B mainnet (= trigger 绑事实不绑日历)

**A** (= v0.5 testnet 用): 接受公开投票. 简单, code 已经这样.
**B** (= mainnet 切): commit-reveal 2-phase.
- Phase 1 commit: oracle 上链 `hash(vote, nonce)`, 0 公开 plaintext
- Phase 2 reveal: deadline 到 oracle reveal vote + nonce
- decideConsensus 用 reveal 后明文
- 防 herd: commit 阶段独立判断, reveal 阶段同时揭开

### 4 nail-死

1. **Trigger precise**: 第一个 ≥1 **非 KANet operator** 出现就切. "独立" = 不同 ownership / 不同 ASN / 不同 KYC entity. 防 KANet sock-puppet 规避.
2. **Feature flag 同份 code**: 不是两套 code path. v0.5 flag-off (= A), trigger 触发 flag-on (= B). 一次 audit 一次集成.
3. **Mid-market 协议变更禁止**: 切换只对**切换后 create 的 market** 生效. 已存在 market 用 create 时协议跑完. 否则破 marketMetadataHash 不变量 (= 1.8).
4. **Reveal-fail 处理 (= ii)**: 比 silent 罚重. commit-but-no-reveal 是已 commit (= 已知答案) 选择性破坏揭示阶段 = 战略性破坏 consensus = 恶意更明确. silent 可能 daemon 弃票或网络丢 (= 无意), 罚轻.
   - ⚠ **具体倍数待定** (= J1 #488 catch): bond × 1.5 / × 2 / 额外从 Tier 2 stake 砍? Area 10 必落.
   - ⚠ **Tier 1 vs Tier 2 reveal-fail 处理可能不同** (= Owner 5/23 polish): Tier 1 没 stake 没法砍 stake, 可能 bond × N OR governance forced 退出 OR future sampling exclusion. Tier 2 可砍 stake. Area 10 一并 nail.

### 跟 Q10 绑死 — 同一事件

V8 trigger 跟 mainnet Tier 2 开 = **同一事件**. Tier 2 准入开 = B flag 自动开. 不需单独判断 "什么时候切 B".

## 3.10 V7 待 Area 7 — 投票时机 vs 真实结果延迟

比赛结果几小时后才公布 → deadline → verifying grace period? ORACLE_SILENT_TIMEOUT 窗口太短 → 逼 oracle 投瞎.

---

# Area 12 (= 提前 surface) — V0.5 vs Mainnet 切换 + Q10 oracle pool 来源

## Q10 钦定 C: KANet Tier 1 + Open Stake Tier 2 + 渐变

```
Tier 1 — KANet curated (启动期主力, 5-10 个)
  - 公开 onboard 流程, operator 身份 KYC / reputation lock
  - 不收 stake, 但发现作恶 KANet 主动移除
  - sampling 权重起步 90%

Tier 2 — Stake-bonded open registry (= day 1 同步开放)
  - 任何人锁 N KAS 注册为 oracle (= N 是反女巫门槛)
  - 作恶 → bond 罚没 (slash) → 自动出 pool
  - sampling 权重起步 10%

权重渐变:
  - 协议层硬编码 (block height / 时间) Tier 1 权重逐月衰减
  - 不是治理投票可调, 不是手动开关, 是数学公式
  - 目标: 12-18 个月后 Tier 1 权重 → 0
```

### 3 invariant 必 day 1

1. **Sampling pool 来源 on-chain transparent**: 每被抽中 oracle 上链时附 tier 标签. bettor 押注前查 market 详情能看到 "3 oracle 中 2 Tier 1 / 1 Tier 2". 让 bettor 自评 trust assumption.
2. **Tier 1 移除流程公开**: KANet 移除某个 Tier 1 operator 必须发链上 governance event, 理由公开. **不允许静默移除**.
3. **Tier 1 权重衰减是协议层硬编码**: 写进 SilverScript 合约, 不是治理投票可调, 不是 KANet 可单方面延后. 否则 KANet 永远有动机延后衰减 = C 退化成 A.

### 信誉评分 — Phase 5

不阻塞 mainnet.

mainnet day 1 用 transparency metric 替代: 每个 oracle 的 `total_votes / correct_votes` (= 按 consensus 算 correct) 公开. 这不是"信誉评分"是"投票记录", bettor 自看.

真正的信誉评分 (= sybil-resistant / stake-weighted / time-decayed) 等 mainnet 跑半年有真实数据再 design.

### A 是反目标延伸 — C 反退化护栏

- A 简单到危险 = 启动快但 KANet 倒了整个 oracle 池子崩, 违背反目标精神 (= bettor 不信 broker 改成信 KANet, 信任对象换名而已)
- B 冷启不可行 = mainnet day 1 没信誉历史
- C 已被 Cosmos / Polkadot / Ethereum PoS 早期 stress test 过, 工程路径已验证
- 衰减硬编码 + 移除流程公开 = 反 C 退化成 A 的护栏

### ⚠ 4 数字待 nail (= J1 #488 catch, area 10/12 启动前必答)

1. **Tier 2 N 反女巫门槛多大**? N 太低 = 女巫便宜攻击; N 太高 = 没人参与. 真数字 (= 10000 KAS? 100000 KAS?) 必须 calibrate 跟单 market pot cap 比, 否则女巫拿 100 KAS bond 接 100 KAS pot 市场 = 完全 cost-effective 攻击.
2. **权重 90/10 → 0 数学公式具体**? 线性 / 指数 / 12-18 月怎么算 (= block height 触发 vs wall-clock) / SilverScript 硬编码 vs Console 常量?
3. **Tier 1 governance event 形式**? 谁投票移除 (= Owner / KANet operator 集体 / oracle 自身)? 投票门槛多少? 链上 event 格式?
4. **"correct_votes" 定义**? 2-1 disagreement 时无 cons
