PIET
Piet is a web application providing support to understand smart contract architectures. This is approached by generating a graphical representation of such architectures and a possibility to query deployed instances of smart contracts. The graphical representation shows the inheritance structure of solidity contracts. In addition to the inheritance structure the defined enumerations and structs are shown. To provide understanding of one single solidity contract Piet offers an inspector view showing all members of the contract including the inherited ones. The presentation of the contract and the contract members is enriched by documentation labels derived from Ethereum NatSpec tags. Piet also provides an interactive mode enabling to read the state of a smart contract, sending transactions and browsing through events. This is achieved by connecting to deployed smart contracts through an injected web3 object.
Smart Contracts Design Pattern
Design pattern are essential to create secure and efficient software even more in the smart contract world where every bug can have fatal consequences. This talk features a live demo of the development tool Piet and its plugin to access a catalog of smart contract pattern and anti-pattern. The presented Piet plugin queries existing pattern registries, categorizes them and presents the patterns in an enhanced way. A pattern view in Piet consists of its inheritance graph, an example implementation, a description, curated comments and a graphical interface to interact with deployed example contracts. The curated comments are way to inform the developer regarding issues related to this pattern which are not included in the original description.
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.

Casper the Friendly GHOST: A correct-by-construction blockchain
Vlad Zamfir presents their talk titled, "Casper the Friendly GHOST: A correct-by-construction blockchain"
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.
