An Explainer to Decentralized Application (DApp) Development

A decentralized application, commonly known as a dApp, is a software program that operates on a distributed network. Businesses entering Web3 often build decentralized applications to leverage blockchain’s benefits of transparency, decentralization, and security. DApp development requires a shift in mindset from traditional app development. It involves designing for decentralized data storage, implementing token economics, and ensuring seamless integration with blockchain wallets. This article covers the process of decentralized application development and how businesses can benefit from building decentralized applications.

Why do Businesses go for DApp Development?

Here are some reasons why businesses go for Web3 app development:

• Zero Downtime: One of the benefits of blockchain app development is zero downtime. Once a smart contract is deployed on the blockchain, it’s always accessible. The network can continuously serve clients who want to interact with the contract. This constant availability is due to the decentralized nature of blockchain networks.
• Resistance to Attacks: Another benefit of building decentralized applications is security. DApps are inherently more secure against certain types of cyberattacks. Malicious actors cannot easily launch denial-of-service (DoS) attacks against individual blockchain-based applications. This is because the application doesn’t rely on a single, centralized server that can be overwhelmed or taken down.

Tech Stack for DApp Development

Before we learn how to build dApps, let us explore the tech stack required for dApp development:

Backend (Smart Contracts)

• Language: Solidity, Rust, or platform-specific languages
• Development frameworks: Truffle, Hardhat, Substrate, etc.
• Deployment tools: Platform-specific CLIs or web interfaces

Frontend

• Web: React.js, Vue.js, Angular, or any modern web framework
• Mobile: React Native, Flutter, or native iOS/Android development
• Desktop: Electron or similar cross-platform frameworks

Steps for Decentralized Application Development

While dApp development shares similarities with traditional app development, it has unique aspects. The process varies depending on the application type (e.g., NFT marketplace, DeFi lending). Here’s a general approach:

Research and Planning

This is the first step in your blockchain application development journey. Understand the pain points of your audience and find a solution to existing problems. Based on that, determine how blockchain technology can tackle the issue and create a basic outline of your decentralized application. Consider whether you want to enter the DeFi space, tap into RWA tokenization potential, or address other blockchain-related needs.

Smart Contract Development

Place the decentralized business logic of your dApp in a smart contract or a group of smart contracts. All automatically executing functions will be encoded inside these self-executing contracts. For example, if building a Web3 app for asset tokenization, you might include functions for assigning ownership, transferring ownership, and adding token metadata. Blockchain developers code these functionalities into smart contracts using a specific programming language depending on the deployment blockchain.

Frontend Development

This part is similar to traditional application development. The frontend or client-side section will be the face of your dApp where users interact. Create a UI and UX design that determines how your Web3 app will look and what functionalities or features it will offer. You can be creative with the application’s appearance and make it more user-centric. Ensure that navigation in the dApp is smooth and easy.

Centralized Backend Development

Although it may seem to conflict with the idea of dApps, these applications often require a server-based backend. This is particularly true for Web3 applications whose functionality extends beyond crypto transfers. It’s necessary for platforms handling substantial user data that typically won’t fit on a blockchain. This private server will connect to smart contracts and frontend applications to offer functionalities beyond on-chain transactions.

Testing

Testing includes both frontend and backend evaluation. Client-side testing of the dApp is similar to traditional testing, involving unit testing, regression testing, and other standard practices. It requires different tools and testing environments, and the process is quite standardized. Backend testing differs significantly from traditional applications. It’s crucial to test smart contracts to avoid vulnerabilities like reentrancy and frontrunning. Once a smart contract is deployed, you cannot alter or change its code, and any vulnerability can lead to significant losses. So, it is crucial to test smart contracts thoroughly.

Deployment and Maintenance

After thorough testing and auditing, you must deploy your smart contracts on the selected blockchain. This forms the backbone of your dApp’s functionality on the blockchain. Next, focus on your backend and frontend deployments. Host your backend on a reliable cloud provider or dedicated server. Deploy your frontend on a web server to optimize performance and user experience.

Integration is crucial for your dApp’s success. Securely connect your frontend to both the backend and the blockchain. This ensures smooth communication between all components of your dApp.

After deployment, maintenance becomes your ongoing responsibility. Regularly update and patch all components of your dApp. Stay informed about blockchain changes and conduct periodic security audits to keep your dApp secure and efficient.
