What happened
A hacker exploited a bug in Blockstream's Liquid Network wallet to steal roughly 4,000 bitcoins (~$340M), then returned ~3,400 bitcoins after Blockstream fixed the bug. About 600 bitcoins (~$47M) remain under the hacker's control, and Liquid Network operations are paused pending further security fixes.
Why it matters
This is a notable crypto security incident but has no direct impact on AI/ML, developer tooling, or SaaS infrastructure this audience ships with. Builders working on crypto custody or settlement systems should note that even a 2018-era production wallet had an exploitable withdrawal bug, but most attendees can skip this one.
Discussion angle
Brief mention only: the 'white hat' extortion pattern—hacker returns funds conditional on a fix—raises questions about bug-bounty vs. coercion norms that could surface in any infrastructure sector.
