This video covers what decentralized apps, or DApps, are and why they will change how some kinds of software is developed.
- [Instructor] Decentralized apps, or DApps,…are applications that run on a blockchain.…The blockchain enables apps to run…without having to have a central location…like a web URL to go to.…This opens up a whole new breed of applications.…Let's discuss how DApps work and…why this is a radical evolution in technology.…The word DApps is simply short for decentralized apps.…So let's take a step back and look…at centralized applications and how they function.…Whenever we go to a centralized app,…we're either going to go through a mobile app…or through a web URL.…
Whichever way we go through, it's going…to interact with the same core functionality…at a central point.…All of the functionality will reside…on a server, or servers, or virtual servers…and all of the data will be stored within that environment.…Some problems with this model, for starters,…because it's a centralized location,…it's vulnerable to a distributed denial of service attack,…where the server can be taken down…or it can effectively block other people…
