How To Develop Decentralized Application?

Introduction

The Decentralized Applications popularly known as DApps are not regular Mobile Applications, instead, they are software programs running on the blockchain or P2P network. Thus, they are outside the control or purview of any single entity. DApps are widely used for gaming, finance, and social interacting domains and are often built on the Ethereum platform. So, let's understand how these DApps are developed by experts across the world. 

STEP 1: Build A Smart Contract  

Building a smart contract or a combination of smart contracts is the first step toward developing decentralized applications. It's only the smart contract that defines the logic of dApp. It defines how the dApp would perform automatically and includes every tit and bit about the chain of algorithm computation. Since smart contracts function on the blockchain, therefore it is a must to pick a blockchain that supports cross-chain dApps too. However, Ethereum is the most frequent choice of developers as it has a wide user base with existing crypto wallets and makes onboarding faster too. 

STEP 2: Get The Front End Done 

DApps cannot have a normal user interface like mobile or web Apps. The vibe of the dApps is altogether different from regular Apps. Since it's only the user actions that trigger the smart contract functions, not the central servers, therefore there exists minimal effect on the User Interface (UI), However, to develop a captivating User experience for DApps, the planning is of great significance. Start by planning a prototype which might include low-fidelity UI, high–fidelity UI, user testing, and reinforced UI/UX depending on the feedback. It is to be noted smart contact function is only from the user-facing UI and takes some time to execute transactions.  Thus, it is wise to have some animation built on the front end to keep users engaged till the transaction gets verified on the chain. 

STEP 3: Go Ahead Creating Centralized Backend 

As discussed, the Ethereum blockchain is largely used for developing DApps. However, this blockchain requires massive data storage to run reports or envision advanced functionality. This is beyond the scope of on-chain transactions, thus the developer requires a web solution based on a private server to go ahead with creating a centralized backend. Thereupon such an admin portal is connected to the smart contacts and front end to develop additional features for the customers and business owners too. 

STEP 4 : Ensure Conducting Rigorous Test 

Like other App development processes, DApps also need to be tested before launch or deployment. As a result, every new build needs to go through Quality Assurance (QA) process.  During the testing process, front-end Apps are likely to be quite standardized while the smart contract is a little unique as they use testnet for verifying each functionality of the smart contract. Evidently, the smart contract process is tricky, but this is so because once the smart contracts are modified to the mainnet, they would not permit modification any longer. Thus, it is the right time to fix the lurking bugs and ensure that DApp performs as desired.

STEP 5: Time To Deploy And Maintain DApp 

Now, it is time to deploy the Decentralized Application (DApp). The process involves uploading this mobile App to the App Store and Google Play, adding a smart contract to the blockchain, and switching the back–end portal to the live production environment. The third-party services also help to lessen the DevOps efforts that are required for deploying the application. Wherein the maintenance task is like an ongoing process and requires keeping the front–end updated.

Final Words 

Developing the Decentralized Application (DApp) requires great expertise in blockchain technology as one can’t compromise on creating smart contracts due to their immutable nature.  As a result, one shall find an expert team of DApp developers to work on their priority project and this is where www.esrotlabs.com comes to support and take your dream project to greater heights.
