My first attempt at building a decentralized app in this day and age will use Solid Pods and DIDs. The goal? A super simple “BooksWeLike” app—a place where I can review books and see what my friends are reading and enjoying.
What makes this app different is how it handles data. Unlike traditional apps where data lives in a centralized database, my app will let users store their own data in Solid Pods. Think of a Pod as your own personal data vault—you control who can access it and how it’s used. And instead of relying on centralized logins like Google or Facebook, I’ll use Decentralized Identifiers (DIDs), which allow users to prove their identity on their own terms.
The plan for the app is straightforward:
• If you already have a DID or a Solid Pod, you can sign in using your existing accounts.
• If you don’t, the app will help you create them when you sign up.
Of course, part of this journey is figuring out how practical and possible all of this really is. Beyond building the app, I’ll also evaluate the tools, SDKs, client libraries, and documentation available for Solid and DID developers. How well is the building community being enabled? I’ll compare my experience with other distributed ecosystems as I attempt to replicate this app in different environments in the future. Once the app exists across multiple ecosystems, I can explore broader topics like ecosystem interoperability and federation.
These technologies are still evolving, and I’m excited to explore what’s possible—and what needs improvement.
So, what about you? Have you already taken the plunge into the world of DIDs or Solid Pods? Or is this your first time hearing about them? Let’s find out together as I document this journey.
In my next post, I’ll dive into the nitty-gritty of authentication—getting users to log in with their DIDs and connecting them to their Pods. I suspect it’s trickier than it sounds, but that’s all part of the adventure.
