Building a Simple Next.js App with Avail’s Light Client

This tutorial breaks down Data Availability (DA) in blockchain technology, focusing on its core functionality. You’ll build a simplified Next.js app that interacts directly with Avail’s DA layer for hands-on experience. By the end of this project, you’ll understand how DA works through tangible development. We’re creating a decentralized notes application where messages are stored and tracked on Avail’s local DA layer—a simple introduction to blockchain concepts and how they translate into real applications.
