What is dApp?

A distributed application (dApp) is a digital application or program that resides and operates in a blockchain or peer-to-peer computer network and not on a single computer and is not dependent on the control of any of the authorities.

DApps is an abbreviation of Distributed applications Which means it is not controlled by a single organization and they play a vital role in the blockchain world. These distributed applications operate in a blockchain network in a public environment, open source and distributed, without control and central influence.

Here’s a great example of dApps from The cat McGee, Which she mentioned came Twitter space Organized by Hashnode.

You can create a Twitter-like dApp and deploy it on a blockchain, allowing any user to post tweets. Once they are uploaded to anyone, even you (the creator of the apps) can Clear Those tweets.

Some of the features of dApps are

  • It is open source which means its source code is available to common users.
  • When miners successfully contribute to the ecosystem, they are rewarded with tokens.
  • It is decentralized and adopts blockchain technology.

Now that you have a good knowledge of dApps, let’s learn what their benefits are.

The benefits of dApps

DApps have many benefits, however, in this article I mentioned only a few of them such

There is no downtime

There will be no downtime or restrictions because it does not rely on a single failure point like a hosting server instead it runs on a peer-to-peer network of computers.


Data from distributed applications are stored in a public ledger, which keeps track of everything in a safe and transparent way that ensures that no one can tamper with it.

Open source

The open source dApps code is available for review. Because more input can be offered, and the entire ecosystem can be more optimized, progress faster and evolve more safely.

And yes, we all know, everything has both pros and cons, so here are some cons of dApps

Disadvantages of dApps

User / UX experience

It may be more difficult to create user-friendly experiences since setting up the toolbox required to communicate with the blockchain securely properly may be too difficult for the average end user.


Because every colleague on the network must update their node software, running in a complicated environment scattered among colleagues makes maintenance, debugging, and updating difficult.

Fewer third-party DApp apps

Sometimes we need to rely on third-party APIs to collect certain third-party information under the current centralized app structure. We do not have this advantage with DApps because there is not yet a substantial third-party DApps ecosystem.

Because DApps cannot access APIs through a central application, they must connect to other DApps for their API needs, which is also a disadvantage.
