Episode 186: ZKPs for Spam Protection & Decentralized Messaging with Status

This week, Anna chats with Oskar Thoren and Sanaz Taheri-Boshrooyeh from Status to learn about their work on Waku, a decentralized messaging protocol incorporating zk-SNARKs for spam protection. Waku is the successor of Whisper, a messaging protocol that turned out to be too resource-heavy and vulnerable to spamming.
Oskar and Sanaz explain how Waku V2 changes things, from ZKP-based spam protection to how its new networking system based on libp2p and Gossipsub can scale globally.
