Catalyst was built using a combination of technologies to provide a seamless and innovative user experience. Here are the key details on how this project was developed:

Mobile App: The Catalyst app was developed using SwiftUI, a UI framework provided by Apple. SwiftUI offers a declarative approach to building user interfaces and enabled us to create a visually appealing and responsive app for iOS and iPadOS devices.

Backend (Node JS): For the backend, we used Node.js, a JavaScript runtime, to develop the app server. The app server handles various backend functionalities such as user authentication, file storage, and communication with the blockchain network.

Blockchain: Catalyst utilizes the Filecoin Virtual Machine for on-chain backups. We developed the Filecoin Virtual Machine contracts using a development environment for Ethereum projects. These contracts enable the secure storage of media files on the blockchain, providing data integrity and resilience.

Polybase Integration: To efficiently store IPFS hashes, Catalyst integrates with Polybase. Polybase is a technology that enables decentralized and resilient storage by batch processing IPFS hashes and performing on-chain transactions with other IPFS hashes.

Encryption: Each image and video in Catalyst is encrypted using the user's wallet address as the encryption key. This ensures that the user's media files are securely protected and can only be accessed with the corresponding wallet address.

ENS Integration: Catalyst provides a personalized experience by displaying Ethereum Name Service (ENS) names and avatars for users who have acquired an ENS name. This integration adds a unique touch to the user profiles and enhances the overall user experience.
