"Hey fellow devs, I'm excited to start this thread where we can collaborate on building a decentralized To-Do List app using PHP, JavaScript, and MySQL. I've got a rough idea of how the app should work - users can create, read, update, and delete tasks, and the data will be stored on a decentralized database. Can anyone help me decide which decentralized DB to use, e.g. IPFS, Firebase, or something else?"
