What is a decentralized application (DApp)?

A decentralized application (dapp) is an application built on a decentralized network that combines a smart contract and a frontend user interface. On Ethereum, smart contracts are accessible and transparent – like open APIs – so your dapp can even include a smart contract that someone else has written.

How to introduce Dapps?

To introduce dapps, we need to introduce smart contracts – a dapp's backend for lack of a better term. For a detailed overview, head to our section on smart contracts. A smart contract is code that lives on the Ethereum blockchain and runs exactly as programmed. Once smart contracts are deployed on the network you can't change them.

What happens if a dapp is disbanded?

Even if the team behind the dapp disbanded you could still use it. Once on Ethereum, it stays there. Dapps have their backend code (smart contracts) running on a decentralized network and not a centralized server. They use the Ethereum blockchain for data storage and smart contracts for their app logic.
