Decentralized Applications (dApps) Overview
Decentralized applications, or dApps, are apps that run on a blockchain or a peer‑to‑peer network. They do not depend on a single server. This gives you more control over your data and how you use the app.
What dApps Are
A dApp runs across many nodes in a shared network. This setup offers clear benefits:
- No single group controls the app
- Data spreads across many nodes
- The system resists censorship and downtime
Many dApps run on platforms like Ethereum, which support decentralized computing.
How dApps Work
dApps depend on smart contracts. These are programs stored on the blockchain that run on their own. They handle actions and transactions without a middle layer.
Main parts of a dApp include:
- A frontend interface you use
- Smart contracts that hold the core logic
- A network of nodes that check and record actions
Together, these parts allow trustless interactions. You do not need to trust one central party for the system to work.
