What Is a DApp? Decentralized Apps Explained

Like centralized applications, a decentralized application (DApp) is also used to interact with the server to query the data. Both types of applications have the same modules like user interface and server integration. But there is a big difference between them, to know all about decentralized applications or DApps, examine the complete article.

What are Decentralized Apps (DApps)

Decentralized Apps or DApps mean a system not controlled by a centralized authority. Moreover, decentralized authority means there is no centralized authority to read, write and modify your data.

DApp develops on blockchain and works in a peer-to-peer network, which means it doesn’t rely on a single centralized authority and each node in the network would also be a server itself. Furthermore, they have equal rights in the networks and the databases would be stored on each node.

It works on smart contracts, a set of instructions that execute and perform transactions automatically when the given condition would be met. Here the top DApp available in the market are Brave, Golem, TRACEDonate, Aragon Circular, KYC-Chain, Prism, and many more.

Better Understanding Decentralized Apps (DApps)

For instance, if I discuss centralized applications like Google, Facebook, Twitter, Instagram, and many other platforms. Here your data would be stored on the server owned by the company and you have very limited access to it. Moreover, your data could be lost, tempered, and monitored by the centralized authority, they can access your data anytime without your permission. Because they are working as the centralized authority and as guardians of your data. Here multiple users depend on a single authority, which means the single point of failure can break the entire system.

On the other hand, decentralized applications like Github, Wikipedia, BitTorrent, and crypto wallet work in a peer-to-peer network which means each node in the network has equal rights and no one can delete the data.

Most Used Decentralized Applications (DApp)

Examples of the most used decentralized apps:

  • Uniswap
  • Aave
  • OpenSea
  • Audius
  • Upland
  • Steemit
  • Pancake Swap
  • 1 Inch

Advantages Of Decentralized Apps (DApps)

Here are the listed advantages of DApps:

  • It ensures their user’s privacy because they don’t need to submit their personal information while using DApp features.
  • Smart contracts are used between two parties to perform transactions without relying on a central authority.
  • It is immutable and no one can delete or modify the data.
  • It is flexible because you don’t need to code everything from scratch to build your enterprise system.
  • Fault tolerance and highly available until the last node does not stop working.

Disadvantages Of Decentralized Apps (DApps)

Here are the listed disadvantages of DApps:

  • It is hard to maintain because once the data is deployed it is harder to modify.
  • It requires a lot of computational power.
  • Network load can cause network congestion.
  • Another difficulty is to make changes in the code to fix the bug while it is running or after deployment.


A decentralized application (DApp) works in a peer-to-peer network and it is the combination of a front-end user interface and smart contracts. Smart contracts are agreements between two parties to perform the transactions. Moreover, it is a set of instructions and it would be executed when the certain condition between two parties would be met.
