DApp

A decentralized application (Dapp) is an application that is open source, operates autonomously, has its data stored on a blockchain, incentivized in the form of cryptographic tokens as well as operates on a protocol that shows proof of value.

What is the Decentralized Application development process? Generally, the process looks like this:

Whitepaper & Prototype
Token Sale
TGE – Token Generation Event
Implementation & Launch

How is the data stored? To emphasize, the applications must cryptographically store their data and operation records as a decentralized public blockchain.
