What are DApps (Decentralized Applications)?

What are DApps

Decentralized Applications (DApps) are blockchain-based applications that allow users to interact with smart contracts deployed on the blockchain. It enables users to engage in transactions directly with one another as opposed to relying on a central authority.

Decentralized applications include a frontend and a backend as the two important components in their design. The frontend helps in communicating with the user, while the backend code is basically a smart contract.

The front end of the decentralized application is actually the code executed on the user side of an application. It basically serves as the interface for communication between the user and the application. In addition, the frontend of dApps also includes a digital wallet that serves different functions. DApps (also called “dapps”) are outside the purview and control of a single authority.

DApps don’t run on centralized servers either. An advantage decentralized platforms have is they’re invulnerable to all types of attacks, as there’s no physical device to target. Not only does this make the network more secure, but it also means there’s no downtime. Accessing these applications is always possible.

A DApp can be public or permissioned. Public DApps are those which anyone can be part of, in other words, they are permission less, whereas permissioned DApps are those which are not open for everyone to join, so you will need permission to join. A permissioned DApp is called a consortium DApp when the participants of the DApp are enterprises and/or government entities. Similarly, when the participants of a permissioned DApp are only enterprises, then we can call it an enterprise DApp.

Advantages and Disadvantages of dApps

benefits of using dapps

Many of the advantages of dApps center around the program’s ability to safeguard user privacy. With decentralized apps, users do not need to submit their personal information to use the function the app provides. DApps use smart contracts to complete the transaction between two anonymous parties without the need to rely on a central authority.

Existing on a P2P network of computers, it doesn’t rely on a single point of failure like a hosting server. This ensures no downtime or restrictions. Dapps are open source. This encourages faster and more secure development of the ecosystem.

Disadvantages of using dapps

The use of dApps is still in the early stages, and thus it is experimental and prone to certain problems and unknowns.

Pros

Cons

Promotes user privacy

Experimental, may not be able to scale

Resists censorship

Difficult to make needed code modifications

Flexible platform enables dApps development

Challenges in developing a user-friendly interface

Trustless Computation

 

What Is the Difference Between a Centralized and Decentralized App?

A centralized app is owned by a single company. The application software for a centralized app resides on one or more servers controlled by the company. As a user, you’ll interact with the app by downloading a copy of the app and then sending and receiving data back and forth from the company’s server.
