## Impact of Tornado Cash: a Builders Perspective
In this podcast, Anna and Martin Köppelmann, Co-Founder of Gnosis discuss the OFAC sanctions against Tornado Cash and the impact this has had on builders in the community. They specifically focus on how the Tornado action helped reveal centralizing forces in Ethereum as well as the need for decentralization.

## Elliptic Curve Cryptography: Trusted Setups 
Successful cryptography is cryptography that transforms legible data into digital-static. Before we go big, let's wrap our minds around something simple. An instruction manual for creating a permanently secret number. Check out this [@SalomonCrypto](https://twitter.com/SalomonCrypto) thread.

## How PLONK Works: Part 1
PLONK is a state-of-the-art zk-SNARK proof system. Previous zk-SNARKs such as Groth16 have circuit-specific setup, which requires a new trusted setup for any new circuit. PLONK’s trusted setup is universal, meaning it can be initiated once and reused by all circuits. It is also updatable: one can always add new randomness till one is convinced the setup is not compromised. This article will explain the core ideas on how to prove a computation using PLONK.

## How PLONK Works: Part 2
In Part 1, they have only covered one type of constraints: gate constraints. In this article, they cover the other type: copy constraints. By [@sinoTrinity](https://twitter.com/sinoTrinity)

## HyperPlonk: Plonk with Linear-Time Prover and High-Degree Custom Gates

This paper moves Plonk to the boolean hypercube which removes the need for using FFTs and makes Plonk linear-time and eases parallelization. It also enables high-degree custom gates. By Binyi Chen (Espresso Systems), Benedikt B ̈unz (Stanford University, Espresso Systems), Dan Boneh (Stanford University) and Zhenfei Zhang (Espresso Systems).
