zkMesh: March 2021 recap

zkmesh.substack.com

Welcome to zkMesh - a monthly newsletter about the latest in decentralised privacy-preserving technologies, privacy protocol development and zero knowledge systems research. zkMesh is put together by Mikerah (HashCloak) and Anna (Zero Knowledge Podcast, zkSummit). 

It includes links to the latest research, useful articles, videos, podcasts, tweets, tools, project updates and events. Expect a new edition at the beginning of every month and be sure to share and subscribe!

Announcement: On April 22nd, Anna will be hosting a ZK Jobs Fair. If you are looking to meet with some of the best zk projects or possibly find your next dream job working on zk tech, please do apply to attend here. This is a satellite event to the ZKProofs Workshop.

A short thread on the recent announcement on eprint by Schnorr about "destroying" RSA. Schnorr has an excellent track record on lattice algorithms, and has made major contributions. The eprint paper presents ideas for SVP that may be worth study. I have no time to comment. 1/7

An attempt at an explanation-in-pictures for how bulletproof-style polynomial commitments work (relevant to Halo and potentially future ethereum upgrades for better scalability) I welcome feedback! I'm trying to experiment with new approaches to make crypto math more intuitive.
