Quantum Advances, Hybrid Signatures and SNARKs to the Rescue with Dan Boneh

In this 400th episode, Anna Rose welcomes back Dan Boneh, professor of computer science and electrical engineering at Stanford University, for a wide-ranging conversation on quantum computing, post-quantum cryptography, and the evolving role of ZK. They discuss Google's recent quantum algorithm announcement—what the paper actually showed, why it was proven in zero knowledge, and the cryptographic ideas embedded in the work. Dan shares his perspective on quantum timelines, the risks of rushing the post-quantum transition, and why algebraic signatures deserve more attention than hash-based ones in the blockchain world. The conversation covers hybrid signature schemes, the web's quiet transition to post-quantum cryptography, and the intersection of AI and ZK. Dan also highlights witness encryption, explains why encrypted mempools are generating new research questions, and closes with an update on the Ethereum Foundation's Proximity Prize. Related Links
