 ## 未发布
 
+### 第四阶段：Web3 黑市与 Ponero（进行中）
+
+- 人脉网络新增"Web3 黑市"（前置：Web3 治理社区，1500）：黑市派系在链上的实体；终端多一页"黑市"，需要黑市声望 ≥ 10，镇压期间下线。
+- 现货柜台：每周刷新一批违禁品（游戏已有的 32 种，低 / 中 / 高三档随声望 10 / 40 / 80 放开；件数 4 + 声望/40），价格 = 游戏基础价 × 1.3，只收 PSC / CRT / CRA / Ponero，不收 CRC。付出去的币连同按比例的污点留在卖家那边，货放进储藏区，不带赃物标签。
+- Ponero 兑换处（声望 ≥ 30）：任意币兑入 Ponero 时这部分价值的污点留在原地，兑入、兑出各收 8%，每天额度 1000 信用点；Ponero 价 = PSC × 0.5。从 Ponero 兑出的币在出金审查里按"刚出混币器"加重。
+- 游戏内验证：声望 75 时上架 5 种；用 CRT 买一把左轮 312 点，余额 3000 → 2688，污点 2000 → 1875（按付款占钱包的比例）；5 PSC 兑入得 9.2 Ponero（500 × 0.92 / 50），当天额度剩 500。
+- 还没做：订单（托管、送货、死投点）、平台跑路、包裹截获、蜜罐、受控交付。
+
 ### 第三阶段：数值调优（进行中）
 
 - 混币器每轮手续费 6% → 4%；用币付款的顾客概率提到上层 30%、黑市 50%、革命派 50%、下层 25%，并多付 12%（溢价只加在币数上，污点仍按货值算）。
