Introduction to Snarks
Blockchains are a hostile world were all information is public and computations are expensive. A technology called zkSNARKs is coming to the rescue: It allows both a tremendous speedup in verifying the correctness of a computation while at the same time it hides the private details from prying eyes. This talk tries to give an idea about how and why it works.

Farcaster frames: building embeddable Ethereum apps
Frames are an open standard for creating embeddable, interactive apps in social media feeds and on the web. They help solve one of the hardest problems for Ethereum dapp developers: distribution. Although frames originated on Farcaster, it's now possible to build cross-platform frames that work on Farcaster, Lens, XMTP, and the open web. In this hands on workshop we'll introduce the core concepts behind frames and build a simple frame app that interacts with a smart contract.
