The Finale: Liquid's 4,000 Bitcoin, the Caching Bug, and 50 Days for Freedom Wrapped

The last day. Brady opened with the count, 37 shows in 50 days, and the campaign's frame: political independence 250 years ago, monetary independence now. Yan Pritzker, Frank Corva, Suze and Alec on stage; Unseen Finance returned at the end.
The Liquid hack, plainly. On Sunday somebody sent 4,000 L-BTC to SideSwap's peg-out and the Liquid Federation paid out real Bitcoin. The L-BTC had been created from nothing. Blockstream paused the sidechain and 3,400 Bitcoin came back Monday.
⭐ Yan on what broke: a caching bug, not anyone's keys. "The only two hard problems in computer science are naming and cache invalidation." Two transactions shared one cache key, so validators mistook a fake for one already checked.
Why it is not Bitcoin. Yan: Liquid is an 11-of-15 federation of companies with its own database and rules. "This is a separate thing, this is not Bitcoin itself." Lightning is built on Bitcoin script; Liquid is not.
⭐ Frank on the 15%. The hackers returned 85% and kept about 600 Bitcoin. His question: will anyone be made whole, and if they keep it, "they're surely not white hats." A Bitcoin Policy Institute lawyer offered to talk.
Yan's verdict on the hat color: gray. Taking everything to beat a black hat is arguable. Keeping a cut is not. "You don't just return a wallet and take a bunch of stuff out of it."
Suze's question: Bitcoiners are ruthless about added trust assumptions, so why did Liquid get a pass? "Were we discerning enough?" Leave the base layer and you take on another code base and another set of failure points.
⭐ Yan on open source in the AI era: it stays because every open project gets red-teamed by the whole internet. Closed systems get hacked too, "we just don't hear about them." The base chain is "the ultimate boss" nobody has beaten.
Yan's bank numbers, read live from the Identity Theft Resource Center: 3,332 reported data compromises in 2025 affecting 280 million people, 739 of them in financial services. "Bank-grade security" is not a standard anyone actually meets.
⭐ Frank's hard question: must the layers be as bulletproof as Bitcoin? Yan: nothing is, and the only path is slow growth. Bitcoin was attacked at $1, then $10,000, then a billion. Early adopters carry the risk.
Yan's rocket-ship rule. Bitcoin Core engineering is closer to launching a spacecraft than shipping web software. "Years of careful review, study, simulations on other chains." Test new tech on other coins for two years first.
Suze asked whether ossification risks losing the skills to change Bitcoin in 50 years. Frank and Yan: no. Ossification is no new features, not no developers, and AI has widened who can work on cryptography and game theory.
Yan on open-weight versus hosted AI: the same debate as open source versus closed, and open source won the internet. His advice to companies: externalize memory, skills and harness so you can swap models. Swan built its own.
Unseen Finance returned with a proposal: these incidents are a credibility problem for the services on top of Bitcoin, not for Bitcoin. His fix, borrowed from banking: a self-regulatory body plus an insurance pool that service providers pay into.
Brady's tally at the close: Cory, Yan, Steve, Alec, Isaiah, Matt and Brandon from Swan; Larry Lepard three times; Parker Lewis, Daniel Batten, Tom and Callum, Guy Swann, Ryan MacLeod, Alana, Bob Burnett, Roxana. Suze made 35 of 37.
The close. "We have the tools, we have the knowledge, we have the culture, we have the determination." The half-price buy fee ends today; limit orders placed today keep it. Yan's last word: take security seriously, "go play with AI."
