How to become a dApp Developer?


Decentralized applications (dApps) have gained significant traction recently due to their new-age safety features and benefits. A dApp is a software application that operates on a decentralized network, such as a Blockchain, and utilizes smart contracts to execute transactions. These applications are designed to be trustless, transparent, and secure, as they do not rely on a central authority for their operation. The importance of dApps lies in their ability to offer a new level of transparency, security, and privacy in various industries. 

These decentralized applications are built on Blockchain to use distributed ledgers and offer immutability in data storage and management for these applications. With the increasing demand for decentralized application solutions, the need for dApp developers has grown exponentially in the mobile and web application development industry. In this guide, we will give you a strategic roadmap to learn dApp development and explore the steps necessary to become a dApp developer and build a career by utilizing opportunities available in this emerging field.

Let’s get the ball rolling! 

Skills Required for dApp Development 

For credible dApp development learning, you need to be proficient in a collective skillset of numerous programming languages, including Python, Java, and various others. It also includes a thorough understanding of crucial technical pillars of application development like Framework and Protocols. Given below is a detailed individual description of key technical skills and technologies to help you learn dApp development by efficiently strategizing your upskilling as a dApp developer: 

Popular Programming Languages

In dApp development, programming languages are critical in building smart contracts and web3 applications. Solidity, JavaScript, and Python are some of the most popular programming languages used in dApp development. Solidity is a high-level language used to write smart contracts and build applications on the Ethereum Blockchain. It is similar to JavaScript in syntax and is used for developing complex decentralized applications. Solidity offers various features like inheritance, interfaces, and libraries, doing the writing, deploying, and testing of smart contracts easily. 

Second in the series is JavaScript, a popular programming language used in front-end web development. It is used to build decentralized applications that run on web3. JavaScript is also used with other frameworks like React and Angular for the front-end development of decentralized applications.

Python is the third most popular language, a general-purpose programming language used for various applications, including dApp development. It is used in the back-end development of decentralized applications, especially for developing scripts to interact with smart contracts.

Blockchain Technology

Blockchain is a new-age decentralized, digital, distributed ledger technology that allows the platform to facilitate secure and transparent transactions without intermediaries. It is the foundational technology of dApp development, as it enables the creation of decentralized applications. Blockchain technology offers transparency and immutability and eliminates centralization, making it an ideal platform for dApp development. The most popular Blockchain platforms for developing decentralized applications are Ethereum, EOS, and TRON.

The leader among numerous Blockchains in the industry is Ethereum, a Blockchain platform that enables the creation of decentralized applications through smart contracts. It is the most popular Blockchain platform for dApp development due to its robustness, flexibility, and widespread adoption.

In the second place, EOS is another Blockchain platform for developing decentralized applications. It offers high throughput, low latency, and low transaction fees, making it most suitable for developing decentralized applications that require high-speed transactions.

Last but not least, TRON is among the most popular and globally used Blockchain platforms enabling decentralized applications for the entertainment industry. It offers low transaction fees, high throughput, and seamless integration with other Blockchain platforms.

Decentralized Protocols

Decentralized protocols can be explained as specific sets of rules to govern the behavior of decentralized applications. They are used to ensure that these Blockchain-based dApps are secure, transparent, and autonomous. The most popular decentralized protocols among Web3 and decentralized application developers include InterPlanetary File System (IPFS), Whisper, and Web3. These protocols enable decentralized storage, messaging, and communication between decentralized applications.

The leader in decentralized protocols, IPFS is a decentralized protocol that enables the storage and distribution of files in a distributed network. It offers features like versioning, content-based addressing, and deduplication, making it most suitable for sharing and storing large data packets in a decentralized manner. Another popular decentralized protocol is Whisper. It offers message filtering, end-to-end encryption, and topic-based subscriptions, making it ideal for developing decentralized messaging applications. Coming to Web3 is also a globally popular decentralized protocol that enables the communication between dApps and the Blockchain. It offers features like active account management, smart contract interactions, and transaction monitoring, making it ideal for dApp development.

Smart Contracts

You can understand these as self-executing commands written in a contract without physical presence. These commands are directly fed to the development code that automates contractual agreements among transaction parties. Smart Contracts are the fundamental building blocks of decentralized applications written in programming languages like Solidity.

They allow the creation of decentralized applications that perform various functions like storing data, storing data, and executing business logic. Their Blockchain-based execution ensures their tamper-proof, transparent, and autonomous nature. Smart contracts are used in various applications like NFTs (non-fungible tokens), DeFi (decentralized finance), and supply chain management. Their key benefits include enhanced security, reduced transaction costs, and transparency, among others on the list. 

Distributed Data Management

Distributed Data Management is a critical aspect of dApp development, as it enables the storage and management of data in a decentralized manner. In dApp development, distributed data management is achieved through decentralized databases like Ethereum Swarm, IPFS, and BigchainDB. 

Relevance of Framework and Protocols in dApp development

Protocols and frameworks are crucial for dApp development. A protocol is a set of rules and standards that define how a decentralized network operates. It provides the foundation for dApp to interact with the Blockchain network and ensures that the transactions are secure and transparent. Without a protocol, a dApp could not communicate with the network or execute transactions. On the other hand, frameworks provide developers with tools and libraries to build and deploy dApps quickly and efficiently. A framework is a pre-written code that offers developers a set of tools and features to work with, allowing them to focus on the application’s functionality rather than the underlying infrastructure. Frameworks make it easier for developers to write code and build dApps without worrying about the Blockchain network’s lower-level details.

Some Web3 development companies build need-specific frameworks allowing developers to deploy Web3 mobile applications using Web2 protocols. One such framework is React Native, a popular mobile application development framework that enables developers to build cross-platform apps using a single codebase. React Native can be used with several Web3 development frameworks, such as Truffle and Embark, to create dApps that can be deployed on mobile devices. 

To enable the deployment of Web3 mobile applications, these frameworks use several Web2 protocols, such as HTTP and WebSocket, to communicate with the Blockchain network. For example, Embark uses the WebSocket protocol to connect to a local or remote Ethereum node, while Truffle provides an HTTP API for developers to interact with the network. One of the challenges of deploying Web3 mobile applications is mobile devices’ limited computing power and storage capacity. To address this, some frameworks, such as React Native, use off-chain solutions, such as IPFS and Swarm, to store data and reduce the load on the Blockchain network.
