Hardware acceleration, proving performance, security posture, supply-chain integrity, and the architecture decisions that determine what privacy-preserving systems cost to run. Written for the people who have to ship these systems, not only evaluate them.
Engineering
Vitalik Buterin published a long essay on formal verification today. It argued that pairing AI-generated code with machine-checked mathematical proofs is the right response to AI lowering the cost of finding exploits. The gist is that Lean is the language of trust, and ZK proof systems and post-
Identity & selective disclosure
Google used a ZK proof to disclose a quantum cryptanalysis result without publishing the exploit. Trail of Bits forged a "better" proof two weeks later. The episode is a stress test of a new disclosure norm, and the technology is stronger for it. An Early Field Test On
