  • Build a Decentralized App with Web5.js

    A 90 minute workshop we'll build a decentralized web app with Web5.js. This library utilizes open standards such as Decentralized Identity and Decentralized Web Nodes to reimagine the account model of the web. Web5.js abstracts away the complexity of decentralization, and allows you to focus on your app development. Instead of dealing with usernames, passwords, and databases, you'll instead authenticate users with their own unique personal identifiers and read and write from their personal data stores. This enables your app to truly go serverless and allows your users to maintain ownership of their identity and data and utilize it across the web.
