Notes on ProtoGalaxy

The idea of these notes is to provide some extra intuition and explainations on ProtoGalaxy’s paper. ProtoGalaxy is a folding scheme which iterates on ideas from ProtoStar paper.


Notes on HyperNova (pdf)

This document contains notes on HyperNova and CCS.


IPA polynomial commitment by hand

This post overviews the IPA polynomial commitment described in the Halo paper, first by providing an overview on the protocol, then by doing a step-by-step example with small values, following the style done in the “Plonk by hand series” from Joshua Fitzgerald, and later by providing a Sage implementation of the protocol.


Notes on FRI (pdf)

This document contains notes on FRI low degree testing and the trick to convert it to a polynomial commitment scheme.


Implementing the powers of tau contributor

In the following notes we go over the ideas behind the Powers of Tau ceremony, how participants contribute and how the contributions are verified (logic & code). We focus on the Ethereum’s upcoming KZG-Ceremony.


bLSAG ring signatures overview

Lagrange Polynomial Interpolation and Shamir secret sharing

Overview of Langrange Polynomial interpolation and Shamir’s secret sharing.


Batch proof in KZG Commitments

The benefit of batch proof is that allows us to proof multiple points while the proof size remains constant to one \(\mathbb{G}_1\) point.


Notes on KZG polynomial commitments

In the following notes I’ve tried to summarize the KZG Commitments scheme with the concepts that helped me to follow the reasoning.


Notes on blind signatures over elliptic curves

In this notes, we will cover the scheme proposed at “New Blind Signature Schemes Based on the (Elliptic Curve) Discrete Logarithm Problem” paper by Hamid Mala & Nafiseh Nezhadansari.
