It was proposed by Taher ElGam...

Rate Limiting Nullifier (RLN) Review I recently had the pleasure of conducting my first security audit of a Zero Knowledge Proofs (ZKP) protocol. The protocol in question was the Rate Limiting Nullifier (RLN) Zero Knowledge Proofs Protocol, with its circuits written in Circom. My main focus during this review was on the Circom Circuits of the Z...

This article would provide an in-depth understanding of how product codes from algebraic coding theory can be applied to Danksharding to improve Ethereum’s scalability. It would cover the fundamentals of product codes, their application in Danksharding, and the potential benefits for Ethereum’s network. Product Codes and Their Relation to Da...

In this blog post, we will explore an efficient method to compute the Frobenius automorphism for the BN254 elliptic curve. The BN254 curve is a pairing-friendly elliptic curve that is widely used in cryptographic applications hackmd.io/@jpw. We will exploit the fact that $(p−1)/2$ is odd to compute the Frobenius automorphism efficiently. What i...

Overview We will implement dot product of two vectors of size N using Zero Knowledge Proofs (ZKP) in Circom, Halo2, . According to k12.libretexts.org, the dot product of two vectors A and B of size N is given by: A.B = a1*b1 + a2*b2 + ... + aN*bN Overview Process Flow of a Zero Knowledge Proof Circom Circuit for Dotproduct of Two Vect...

Overview The paper aimed to improve the prediction of adverse cardiac events in patients with hypertrophic cardiomyopathy (HCM) using machine learning methods. The study found that machine learning models demonstrated a superior ability to predict adverse cardiac events compared to conventional risk stratification. The authors suggest that thes...
