## Workshop plan - Day 1 (Pre requisite Knowledge) - Introduction to key concepts - Introduction to polynomials - Polynomials for error amplification - Schwartz zippel lemma - Polynomial identity problem - Randomness and its role in succinctness - Types of polynomials - Polynomial methods - The Sumcheck protocol - Applications / Aim of Sumcheck - Interactive Sumcheck - Prover logic - Verifier logic - Fiat Shamir - Non Interactive Sumcheck - Coding workshop Setup - Installation of the neccesary tools and libraries - Cloning of the boilerplate repo - Day 2 (Practical) - Implementation of the Sumcheck prover - Writing of the Non interactive sumcheck protocol - Testing the protocol ## Pratical Feasibility ### What are we including as prebuilt components? - Multilinear / Univariate polynomial library with the following methods: - evaluate: evaluates the polynomial at a random input - partial_evaluate: evaluates the polynomial at some partial input, returns another polynomial - skip_one_sum_over_boolean_hypercube: utility function to make the sumcheck prover implementation really easy - Transcript implementation: allows us make sumcheck non-interactive - Verifier: we'd provide a verifier so participants can verify their prover generates a valid proof. ### The sumcheck prover algorithm using the components above - construct the polynomial you want to run sumcheck on - for every variable in the polynomial do the following: - skip the first variable and sum over the boolean hypercube - send round polynomial to the verifier (uses the transcript) - get the verifier challenge (uses the transcript) - partially evaluate the polynomial at the challenge point - repeat ### Participants workflow - clone our `boilerplate` repository - this will contain all the prebuilt components above, and directions on how to modify it - implement the sumcheck prover algorithm - verify valid proof generation using the `verifier` ### How do we ensure feasibility? - I and Francis will do the end to end `participant workflow` process ourselves in less than 15 minutes, only then will we be satisfied.
