Build a Decentralized File Storage Tracker on Rootstock

In this From Devs to Devs episode, Aditi builds the foundation of a decentralized file storage dApp using Rootstock, IPFS, and Pinata. She first explains how Rootstock extends Bitcoin with smart contract capabilities, then breaks down what IPFS is, why pinning services like Pinata are important, and how decentralized storage fits into the Web3 ecosystem.

You’ll then learn how to set up Foundry, create a full smart contract for uploading, storing, retrieving, and deleting IPFS-based file metadata on-chain, run tests, and prepare a deployment script. This video sets the groundwork for Part 2, where the frontend will be implemented.
