GKR Protocol (Notes)

• an Interactive Proof (IP)
• can be turned into a zkSNARK with PCS and Fiat-Shamir
• designed to delegate computation for arbitrary computation rather than the specific sum-check computation

Sum-Check Protocol (Notes)

• one of the most important Interactive Proof for verifying the sum of a multi-variate polynomial over the Boolean Hypercube
• Prover’s perspective: allows the Prover to prove to the Verifier that the sum is correct
• Verifier’s perspective: allows the Verifier to reduce its computation when calculating the sum by trustlessly delegating the computation to a Prover
• introduced by LFKN92

A Gentle Introduction to ProgCrypto

When I first heard about ProgCrypto (Programmable Cryptography) during Devconnect 2023, I was drawn to see how this simple term encompasses so many different kinds of cryptography techniques. As I read 0xPARC’s ProgCrypto book, I got a peek at how some of these protocols work at their most fundamental level.

Plonkathon

I finally got a chance to try out the exercises from Plonkathon by 0xPARC, an educational implementation of PLONK. It follows closesly to the paper which is what makes it such a good resource to reinforce one’s learning (or to start learning) on PLONK.

ZKP Projects Landscape

There has been a lot of developments in the Zero Knowledge space recently. As someone who’s new in this field, I find all the different projects and the proof systems that are used to be overwhelming. Let alone diving deep into any of the proving system and understand how they work.

Claiming My Free OpenVPN clients

My NordVPN subscription allows up to 6 devices connected simultaneously. This isn’t enough and has caused some of my devices to drop their VPN connections when new devices come online.
