zk-SNARKs: A Privacy and Security Guide to Proving Without Revealing
from Faraday FM Hosted by Aegnus
Every payment on a public blockchain is like handing a bouncer your whole driving licence when all he needs to know is your age. In this episode, Aengus explains zk-SNARKs, the cryptography that lets a network check that rules were followed without seeing your data. He traces the idea from a 1985 MIT paper to Zcash, Groth16 and Tornado Cash, then takes it apart letter by letter in plain English. Then comes the honest part. Aengus walks through real failures, including this year's emergency fix to Zcash's Orchard pool, found with AI-assisted auditing, and the Veil Cash and FoomCash verifier exploits. He also covers the legal picture around Tornado Cash and closes with practical privacy and security tips. To finish, he explores FOG, a small web game that turns sealed notes, clean wallets and anonymity sets into something you can feel. zkSNARK game: https://thefog.pages.dev This episode is for educational purposes only and is not financial or legal advice.
