A Gentle Introduction to the MPC-in-the-Head Transformation

In this blog post, we dive into the fascinating world of zero-knowledge proofs using the MPC-in-the-Head transformation, a clever method that constructs proof systems from any secure multiparty computation protocol. Originally proposed in 2007, this transformation uses a creative approach involving "imaginary parties" to prove knowledge without revealing it. We explain how this technique can be applied to develop post-quantum signature schemes, providing insights into its practical implications and efficiency. By exploring these concepts, readers will uncover a unique intersection of cryptography and computer science.

noname meets Ethereum: Integration with SnarkJS

We're excited to share that our programming language, noname, now supports R1CS, making it easier to write zero-knowledge (ZK) circuits and deploy them on Ethereum using SnarkJS. This update introduces an alternative to the common Circom language, with a simple and intuitive syntax inspired by Rust and Golang. In this post, we illustrate how to deploy a noname-based Sudoku circuit on Ethereum, demonstrating core benefits like proving a solution's correctness without revealing it. Dive in to explore how noname could potentially unify the fragmented zkSNARK ecosystem and simplify your circuit writing process!

Variants of KZG: Part II, Multilinear Commitments with PST

In this blog post, we extend the ideas behind univariate KZG commitments to multilinear polynomials through the PST commitment scheme. We derive the multilinear quotient identity, explain how PST commits to and opens multilinear polynomials using a specialized multilinear setup and walk through its opening protocol. We conclude by examining the proof size, prover and verifier costs, and the limitations that motivate other multilinear polynomial commitment schemes.

Detecting boomerang values in zero-knowledge circuits using tag analysis

Ever wonder how zkApps ensure their execution is spot-on? This post digs into the idea of *boomerang values*, sneaky bugs that can crop up when zkApps mix in-circuit and out-of-circuit logic. We explore how these values disrupt your circuit's trustworthiness, especially when variables are reintegrated unverified. Plus, we share how tools like MIRAI's tag analysis can help spot these issues, making your zkApps more secure. Perfect for anyone into zero-knowledge applications or budding Rust enthusiasts looking for insights on taming complex bugs!
