The Timewarp Attack: A Long-Term Threat to Bitcoin Consensus w/ Core Dev Antoine Poinsot
Description
Bitcoin is the most secure network in the world, but it still carries technical debt from its earliest days. Shinobi sits down with Bitcoin Core developer Antoine Poinsot to discuss the Great Consensus Cleanup: a proposal to address four long-standing consensus risks that have existed for nearly a decade. From mitigating the Timewarp attack to preventing compounding validation and resource costs, these changes aim to protect Bitcoin’s long-term security and sustainability.
