Decentralized Applications (dapps)

A Decentralized Application (dapp for short) refers to an application that is executed by multiple users over a decentralized network.

Blockchain and Smart Contracts come with decentralized applications becoming the new type of applications. They can have clients, mobile apps, and servers like original applications, but the key data and operations are kept in smart contracts in a blockchain. Dapps interact with smart contracts by transactions, namely, contract requests, and provide services based on them.
