dm3 - Decentralized, Secure and Open Messaging Protocol
dm3 is a protocol enabling decentralized, open, and secure messaging based on established web3 services like ENS and IPFS. It doesn't rely on any central service. The user has complete control over where their messaging data is stored. By using ENS names and ENS text records as the registry for public keys, the user owns the identity linked to their messages. dm3 comes with a reference implementation for a standalone web application, a widget, and a delivery service.
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.
Ethermint 2.0: Cosmos SDK + EVM
Chris Goes presents his talk on Ethermint 2.0: Cosmos SDK + EVM.
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.
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.
Keynote: Nomic Foundation’s vision for Ethereum’s tooling ecosystem
Nomic Foundation is the nonprofit behind Hardhat. Nomic’s co-founder and CTO will walk you through Nomic’s long-term vision for a community-driven developer tooling ecosystem for Ethereum.
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.
