10月11日黑天鹅事件后，USDS 逆势增长了 20 亿美元。当时大多数项目都在「失血」，但 Sky 没有。
在本期 《Actually You Know》中，Kayla 对话 Spark 亚太区负责人 Tim，深度拆解这背后的逻辑。我们探讨了「Sky 作为中央银行 / Spark 作为商业银行」的宏大架构、131 亿美元的储备金规模、41.6 亿美元的 PSM 缓冲池，以及为什么 Spark 80% 的利润并非来自借贷，而是源于流动性层（Liquidity Layer）。
我们还深入挖掘了治理风险、SKY 代币的高度集中化，以及当你真正拆解数据时，「最安全稳定币」的真实含义。Tim 的最终观点：稳定币市场规模将从 3000 亿美元爆发至 2-3 万亿美元，DeFi 才刚刚拉开序幕。而如果美元发生崩溃，USDS 可能是前十大稳定币中唯一能幸存下来的那一个。

SERIES OVERVIEW
Actually You Know is an interview series from LongTree Labs, featuring fresh conversations with the builders, researchers, and operators shaping the next generation of financial infrastructure — from stablecoins and DeFi to on-chain finance and beyond.
Each episode is designed around one principle: the people actually building these systems may know things you don't — and we're here to close that gap.
Actually You Know. Because you can.
