Building a DApp: Design Principles for Dapp developers
Ethereum's Alex Van de Sande presents on Design Principles for Dapp developers from a UX perspective
Building Consumer Facing Interfaces for Trust in Supply Chains
Provenance is building a platform to make consumer product supply chains more transparent. Taking advantage of Ethereum and IPFS, we’ve been iterating through a number of pilots in different industries, from organic bacon to fair-trade coconuts to enable a simple shared and trusted way to share the proven claims behind our products e.g. organic or proof of payment of fair wages, and link that to the flow of batches of product. Throughout this journey, we have learnt a lot about industry needs, working with both small and large retailers and brands. We’ve also forged partnerships with sustainability standards e.g Soil Association organic and other data systems that we can connect to enable verification of claims and inputs for our Ethereum based app e.g. Sourcemap. User centred design is core to the work at Provenance – exploring how we can make blockchain backed data appear differently on the frontend and provide accessible links to inspect the chain. As a social enterprise largely built through grant funding and with the support of academia we are keen to share our learnings with the developer community and gauge interest in forming a group around the development of blockchain backed interfaces for trusted data sets.
Layer2 Design Patterns - (enhanced from previous submission #1251)
Continuing previous research I’m interviewing all Layer2 solution providers, exploring current solutions, their problems, the UX patterns and user-research being done. The interviews are focused on extracting knowledge from the companies own user-research, if available: only a few of these projects have actually launched and have real users and even less have performed real user-research. The only company I’m partially affiliated with, Abridged, will launch 7 apps by EthBerlin and there are 13 more launching in September. For once Layer2 tech allows to have direct user contact since most flows ask for user emails.I hope there will be enough users to gather some data which I’d like to share at Devcon, although at this time I can’t guarantee it. Even so, this talk will allow viewers to quickly learn about all Layer2 UX patterns in one session, learning about the differences between the UX mechanics of payment channels, Plasma, (Generalized) State Channels, maybe sidechains, their pros-and-cons, how users enter and exit these systems, how and what they understand about decentralization, what are the open design problems of the space, and accelerating their knowledge of Layer2 solutions which hold the promise to onboard real users onto the decentralized web
Speedrunning chain abstraction EIPs
We look at different EIPs in pipeline across the CAKE stack and how they relate to chain abstraction.
Universal Ethereum Logins
A modest proposal to improve usability in Ethereum apps by removing a lot of the friction created by the usual login system: Your users can use your app without needing to install anything, buy ether or even type a password -Users are identified by a ENS username, and not a hex address -Users can use tokens to interact with your app, and you can even give out some of them free to encourage usage -Users are in control of their identity and any assets that are tied to them, and can take them to other apps -When users log into their identity with other apps, these act as second or third factors authenticators. While the app relies on a server, the server’s only job is to relay messages to the chain and pay ether, and the user can use any server they want. This is all achieved by using client side signed messages and multiple standards. Live code will be presented.
A journey to the center of the eth: How the Gas Station Network improves the UX in Ethereum
The Ethereum developer ecosystem is in constant change. Undoubtedly, teams have started to leave the development of Smart Contracts in the background to focus on the development of decentralized applications, and on how to eliminate friction points between users that might not know anything about Blockchain but still need to interact with it. But developer tools are still important and they have to be simple and secure to use. In this talk we will explore how the Gas Station Network is implemented to redefine the interaction between users and DApps in a way that they don't need to have any knowledge on mnemonics, private keys, transactions or gas costs. Moreover, we will go through a set of tools that the OpenZeppelin team developed to make this transition from regular DApps to gasless DApps in a super easy and fast way.
Jaguar. Tinybox. Strawberry.
It’s been nearly a year since the first wave of dapps, and while we’re still reeling with excitement, we’re also looking to the future. How do we bring the next generation of users to the decentralized world? How do we stop thinking in terms of thousands of users, and start thinking in millions and billions?We start thinking less about ourselves as developers, and more about the user experience. Until now we’ve been working around onboarding limitations, trying to create as smooth a UX as possible. A year later, and the time has come to stop overcoming limitations. We plan to remove them entirely.In this talk, we’ll focus on some of the biggest pain points that users face, how we’re solving them, and the impact those solutions will have on growing the ecosystem. We’ll explore parallels with previous big inflection points in tech, and how to draw on the past to help make decisions on where to go next. You’ll leave with invaluable tools, tricks, and strategies that will help you build your own successful dapps on the blockchain.
Dark Forest: Lessons from 3 Years of On-Chain Gaming
We'll present an overview of learnings from 3 years of building and running Dark Forest, the first fully decentralized MMORTS, including: why ZK is important for games, what a crypto-native game is and why we should care, designing for emergent player behavior, pushing the limits of Ethereum devex, and social consensus and legitimacy - why is Dark Forest more like chess than League of Legends? We'll also hint at 0xPARC's next crypto-gaming experiments.
Gnosis Safe - Make dealing with crypto a less scary thing
The Safe is the first smart contract based multi-signature wallet targeting mobile users. Using smart contracts as proxies between users and dApps opens the door for many usability and security improvements. New access control schemes can be implemented to allow for 2FA and recovery mechanisms making private key management redundant. Transactions can be sent via relay services, which can be paid in any kind of token. Users won't need Ether anymore to interact with the Ethereum network. Usability and costs for dApps can be improved by batching transactions together making user flows simpler and more intuitive. The presentation will give a detailed overview about the Safe implementation of the different features and how they can be used for future dApp development.More information and a download to the testnet beta can be found here: https://blog.gnosis.pm/announcing-the-gnosis-safe-beta-personal-edition-19a69a4453e8
Recurring meta transactions to power l33t subscriptions!
Dapps require way too much on-boarding. The Ethereum ecosystem needs to push toward mass adoption by allowing new users immediate access to functionality and interactivity without all the hoops to jump through. This means paying the gas for first time users' transactions. Thanks to public/private key pairs, users can sign meta transactions and incentivize desktop miners to pay the gas for them. I will demonstrate how etherless accounts can craft and sign transaction off-chain and send them to a relayer. The relayer, incentivized by the a reward in the transaction, submit the the meta transaction to a bouncer proxy and pay the gas. This also works great for Universal Logins where you have an identity proxy that your etherless devices can transact through.
