@chriscyph @zkv_xyz @chriscyph has open-sourced a Network Request Analyzer Extension for generating templates across several different zkTLS systems using just natural language prompts.

@chriscyph @zkv_xyz @zkv_xyz explains how lattice-based post-quantum crypto (PQC) leverages CPU vectorization for speed, while isogeny-based schemes remain compact but less parallelizable — hardware matters as much as math in PQC performance.

Post-quantum cryptography isn’t just math—it’s a hardware battleground. SIMD vectorisation draws a sharp line: some schemes scale, others stall. Here’s how, according to @PrivacyScaling, CPU architecture shapes PQC performance. 🧵

@chriscyph @zkv_xyz Using the @zkmopro ZK mobile-app toolkit, hackers built several cool projects at @ETHGlobal, including proofs about photo metadata, photo identity verification, and more!

1/🥖 Mopro saw amazing adoption at @ETHGlobal Cannes! Huge thanks to all the hackers who explored ZK mobile-native apps and shared great feedback. We’re thrilled to highlight the Top 3 Mopro-powered projects from the hackathon 👇
@chriscyph @zkv_xyz @zkmopro @ETHGlobal @zksecurityXYZ explains the "query collision" bug they've found with the Halo2 system - essentially allowing a malicious prover to forge proofs by exploiting duplicate queries at the same evaluation point.

We disclosed the issue to the relevant teams—including Zcash, PSE, and Axiom, all of whom have since patched it. While no known production circuits were affected, the bug reveals a surprising vulnerability in the proving system that deserves attention.
