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.
Developing Scalable Decentralized Applications for Swarm & Ethereum
Blockchain-coordinated decentralized applications represent a radical departure from the client-server model on which most of the currently popular web applications are based. On one hand, such đapps’ approach to scalability is more natural as the computing power and bandwidth available for applications grows in proportion to their user base, while on the other hand the lack of a centralized trusted infrastructure under the control of a single — typically corporate — entity raises unique challenges in trust, reliability and coordination. In my presentation, I will introduce some of the principles and practices of architecting and developing such applications, highlighting both the challenges and the unique opportunities for transcending the limitations of the client-server model. In addition to developing the underlying infrastructure, the Swarm team also develops some example applications that, while useful themselves for end users, are also meant as a template and a starting point for independent developers. Using these examples as illustrations, the presentation will introduce prospective developers to techniques and approaches of both replicating Web 2.0 patterns in a decentralized fashion and going beyond their limitations, taking full advantage of content-addressed storage and blockchain-arbitrated interactions. In particular, the basic building blocks of decentralized, community-moderated knowledge bases (such as maps or encyclopediae), social networks and other forms of information aggregation are going to be presented.
Decentralized development: what even does it mean and should we care? (yes!)
Amber Baldet and Patrick Nielsen discuss decentralized development.
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.
