Two new research papers just intensified one of crypto’s most serious long-term risks: quantum computing.
In this episode of The Defiant Podcast, Camila Russo sits down with Alex Pruden, co-founder and CEO of Project 11, to unpack what the latest quantum breakthroughs actually mean for Bitcoin, Ethereum, and the broader crypto ecosystem.
Alex explains why the new papers matter, how quantum computers could use Shor’s algorithm to break the cryptography behind blockchain ownership, why exposed public keys are especially vulnerable, and what “Q-Day” could look like if the industry is unprepared. He also breaks down the difference between theoretical progress and live quantum systems, why some chains may be vulnerable in different ways, and what post-quantum migration could realistically involve.
The takeaway: this is not just a technical curiosity. It is a foundational challenge for crypto, and one the industry may need to start addressing now.
