    Today, I'm absolutely thrilled to announce the launch of @CeloOrg's Plumo protocol! This launch includes a prover service that serves Plumo proofs, a WASM library to verify Plumo proofs, and a Javascript library to fetch and trustlessly verify on-chain data. 1/14

    Happy to share an experiment I've been working on recently: zkpod.ai (follow @zkpodai). It's an @OpenAI-powered bot which has access to all @zeroknowledgefm episodes, with the ability to answer questions. It's hacky and experimental, so be gentle please 🫣. 1/9

    Attested data allows users to prove computation on data that relates to them. Attested sensors are one compelling provider of attested data — be it images, humidity or… audio! @ddkang, @AnnaRRose and I worked on a demo for attested audio: medium.com/@danieldkang/d… 1/8

    As serious professionals, we need to admit that zk is not a mathematical definition, it’s a vibe

    With #ethereum Istanbul now activated, verifying proofs is much cheaper. A Groth16 proof verification costs about 200k gas (and then 8k per input) and PLONK should be similar!
