We've released [a new interactive tutorial on Sumcheck, Multilinear Extensions (MLE), and HyperPlonk](https://sumcheck.zksecurity.xyz) that focuses on implementation rather than just theory. The course includes complete SageMath code and exercises so you can actually build these protocols yourself.

The Sumcheck protocol shows up everywhere in modern zero-knowledge proofs scheme such as HyperPlonk, Spartan, Jolt, and more all. But understanding the papers is one thing; implementing the protocols is another. This tutorial bridges that gap by walking you through working implementations in SageMath, starting with the basics of multilinear polynomials and building up to a complete proof systems.

## Hands-On Learning

The tutorial comes with runnable code examples for every protocol. You'll work through interactive exercises implementing key parts of the protocols yourself: evaluating multilinear polynomials, building the prover and verifier algorithms, and composing multiple Sumcheck instances together.

SageMath makes it easy to experiment with the math directly without getting bogged down in performance optimizations. You can focus on understanding how the protocols actually work, which polynomials get evaluated where, and why the verification works. Once you understand the math, porting to production languages becomes much easier.

The course assumes no prior cryptography or sagemath knowledge. We start from first principles and build up progressively, so whether you're implementing zero-knowledge circuits or researching new protocols, you can follow along.
