Some people say building decentralized applications (dApps) is vastly more complex than traditional web development, but others argue that the foundations are quite similar if you understand the core principles. I’ve been diving into tutorials, and while some parts make sense, the backend infrastructure seems to have a lot of new concepts to grasp. I’m especially curious about the programming languages, database alternatives to traditional SQL, and how smart contracts fit into the overall architecture. Can anyone who’s actually developed dApps shed some light on the typical tech stack they use, and perhaps offer advice for a newcomer?
