What are Dapps? What It’s Role in Blockchain Development?

Blockchain development emergence brought forward many jargons which only IT people can understand despite implementation of a blockchain based business model of various non-IT sectors. One of those jargons is Dapp. Dapp stands for Decentralized application and not being able to understand the concept of DApp is due to nondevelopment of a perfect definition yet. But a Dapp can be recognized through the following features:

  • It is a Peer-to-Peer network which works on a decentralized system with the trustless set of rules.
  • It has an open-source code which is managed by its peers A.K.A participants.
  • Information is stored using the blockchain.
  • Crypto tokens are used as an exchange medium; this reward is given to peers who validate the information storage on the blockchain.
  • Lastly, the token is generated through a cryptographic function.

A Dapp can be built on any programming language which makes calls to its backend.

Other than these, one of the most significant benefits of Dapp is its peers are unknown to one another means they are anonymous. This benefit is also one of the reasons for a Decentralized application to be so successful and largely scalable.

There are two parts of a Dapp, first is frontend which includes HTML coding and another is backend which provides for storing of data. The backend coding is easy as decentralized peers builts that codes collectively, anonymously and independently at the same time. A Dapp can be built on any programming language which makes calls to its backend, but the most popular is solidity used for smart contract development. The smart contracts are based on Ethereum Virtual Machine (EVM) for development purpose. As known about the flexibility for smart contract development through Ethereum, Dapps emphasizes on customized requirements by the participants. Here, Ethereum is a blockchain which has a built-in programming language which allows any participant to develop a smart contract. And this development is based on Dapps so it let the process without any control, not even the blockchain developers can affect the smart contracts.

Type Of Dapps

A decentralized application under blockchain despite having not much coding, it requires efforts to model it out. That is why Dapp development company provide this service at a high price. But for more affordable options and based on one’s requirement, there are three types of Dapp development:

01.Type I

This Dapp includes the development of blockchain from scratch. Bitcoin and Ethereum platform are examples of Type I Dapp development.

This Dapp is a plug-in or an app on the phone which uses Type II Dapp as a platform.

02. Type II

This Dapp development includes using tokens as a means to access it. Tokens are obtained through generation on blockchain or by exchanging with participants with any cryptocurrency or fiat currency if it’s allowed.

03. Type III

This Dapp is a plug-in or an app on the phone which uses Type II Dapp as a platform. This app or plug-in lets one connect with other similar blockchain plug-ins and helps participate in it.

Type I decentralized application are based on requirements of an organization or an enterprise willing to have a private blockchain for organizational use. Also, it requires an ample amount of time and blockchain development companies charges high for blockchain development from scratch. Type II and Type III decentralized application development is more affordable and less time-consuming for individual or more use.
