Hello! That's an excellent question! It's a common query for many people new to blockchain. I'll try to explain it in simple terms, so you can quickly grasp the key points.

You can think of it this way: the biggest difference between the apps we use every day (like Taobao, WeChat, Douyin) and DApps (Decentralized Applications) actually lies in the "invisible" backend – that is, how their brains and databases operate.

Let's use an analogy:

  • Traditional Web App = A Central Bank
  • DApp = A Public, Transparent Ledger, where Everyone Holds a Copy

Traditional Web Apps: Everything Answers to the "Central Bank"
