In this episode, Bitcoin veteran Jameson Lopp discusses the growing threat of quantum computing to Bitcoin’s cryptography. He breaks down his new Bitcoin Improvement Proposal (BIP) that aims to prevent a catastrophic supply shock by encouraging a network-wide migration to quantum-resistant addresses. Lopp explains the nuances of Shor’s algorithm, possible migration schemes, controversies around locking old funds, and his phased plan to protect user assets. We also touch on the state of Bitcoin L2s, BitVM progress, mining risks, and the philosophical tension between ossification and innovation. Enjoy!
