Why Privacy Is Finally Making A Comeback (...And What Comes Next)
23 Dec 2025 · 44:28
Jan Camenisch of Rialo and Jens Groth, chief scientist at Nexus, join The Rollup to explore the trade-off between privacy and verifiability in cryptography. They discuss why zero-knowledge virtual machines can cost 100,000 times more than native computation, whether quantum resistance is as urgent as often claimed, and how blockchains could become the mechanism for verifying AI agents and detecting deepfakes. The two also cover recent progress on ZK proving bottlenecks and passport based identity proofs.
