In the digital age, Blockchain technology is like a tsunami, dramatically transforming the way we interact, transact, and build applications. One of the most groundbreaking products of Blockchain is the DApp (Decentralized Application). So what is a DApp? Join us as we explore this world of potential, where technology intersects with finance, opening up exciting investment opportunities.

What is a DApp?

Simply put, a DApp (Decentralized Application) is an application built and operated on a Blockchain platform. Unlike traditional applications, DApps operate independently, not under the control of any organization or individual. All data and source code of a Decentralized Application are stored and distributed on the Blockchain network, ensuring transparency, security, and immutability.

Key features of DApps

Decentralization

This is the core characteristic that gives Decentralized Application their name. Unlike traditional applications that operate on a centralized server, DApps run on a blockchain network where data is distributed across multiple nodes. This offers significant benefits:
