EP. 113 | Quantum, Hacks, and Privacy: Inside Blockchain Security with Penn's Brett Falk

If a sufficiently powerful quantum computer came online tomorrow, every token on every blockchain would be a target — Bitcoin, Ethereum, Solana all share signature schemes that pre-date the post-quantum era. The math has been clear since the 1990s. What's been missing is the machine. That uncomfortable truth anchors this week's TRM Talks.Brett Falk, research faculty at the University of Pennsylvania and director of the Crypto and Society Lab, joins Ari to work through what that actually means — why Shor's algorithm threatens every chain, what NIST's 2024 post-quantum standards mean in practice, and why Ethereum is better positioned than Bitcoin to respond. They also dig into the back-to-back Drift and Kelp DAO exploits and what made the DPRK playbook behind them unlike anything we've seen before, and into the cryptographic tools — zero-knowledge proofs, secure multi-party computation, credential-based KYC — that let users prove compliance without turning every business into a ransomware target. The math to thread that needle already exists.
