1/ 🌱 The zkID team published OpenAC: Open Design for Transparent and Lightweight Anonymous Credentials earlier this week with a show proof time of 0.129 seconds. It describes a zero-knowledge identity construction designed to work with existing identity stacks and was purposely

We hardened Sonobe, our folding schemes & IVC library, before its first release. Two audits: one human (@alpeh_v) + one AI (@v12sec). Each caught bugs the other missed, but both independently flagged every critical one. Read more 👇

1/ New post alert! ⏰ Is onchain ZK PQ-ready? Round two of putting WHIR on Ethereum gave us an inconvenient result: small fields shrink proofs but make them challenging to verify. We rebuilt WHIR verifier over a 31-bit KoalaBear field and measured where the gas goes.

EVM Verification of WHIR over a 31-bit Field | PSE
A standalone WHIR verifier over the 31-bit KoalaBear field can verify a 2^22 polynomial opening on EVM with 100-bit Johnson-bound soundness for 5.65 MGas in software, or 4.33 MGas with experimental...

New on the blog: Machina iO's four-part series on circuit-specific decryption keys for FHE. A primitive that lets a decryption committee publish a key for one specific computation and then step away no need for an always-online committee.

We built a real-world OpenAC implementation for privacy-preserving proof of personhood. It uses an existing government-issued credential, proves eligibility in zero knowledge, supports revocation checks, and runs the proof flow on mobile devices. Check threads for links and
