Monitoring an Ethereum infrastructure
Have you ever wondered what goes on under the hood of an Ethereum node? Frankly, most people don't care. If you are, however, running production systems with multiple nodes across geographical locations, knowing what your nodes do internally is more important than you might think.It is a general fallacy to believe that a software either works, or does not. In reality, there is a whole spectrum in between. A software almost never works perfectly, rather there are quirks that may or may not affect your use case. These quirks may manifest only above a certain load or compound as time passes. The only way to build out a robust infrastructure, is to accept that your nodes are quirky. Instead of getting surprised when they break - having no idea what caused it - you must always be aware of buildups and correlations to external stimuli. This talk will present the suite of metrics that Geth exports for monitoring, highlighting why these have been added and why they might be important to you. By correlatinh your own load and use case with Geth's internals, you'll be able to gauge issues before they ever get strained enough to cause catastrophic meltdowns.
Augur
Dr. Jack Peterson presents on Augur (http://www.augur.net/), an open-source, decentralized prediction market built on Ethereum.
Digital Identity
Christian Lundkvist of ConsenSys (https://consensys.net/) presents on digital identity.
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.
Missing Links in the Ethereum Stack
Observations about what developer tools missing from the Ethereum stack, yet currently available to traditional web developers.

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.
