How to become a Blockchain Developer a step-by-step guide

Blockchain technology has taken the world by storm and has become a vital tool in industries ranging from finance to healthcare. As a result, the demand for skilled blockchain developers has skyrocketed in recent years. If you’re interested in pursuing a career in blockchain development, you’re in luck! 

In this article, we’ll outline the essential steps you need to take to become a blockchain developer. From understanding the basics of blockchain technology to building decentralized applications, we’ll guide you through the process step-by-step. 

Additionally, we’ll introduce you to AstraKode Blockchain (AKB), a low-code blockchain platform that makes blockchain development accessible to anyone, regardless of technical expertise. Read on to discover how to become a blockchain developer and join the revolution!

Generally speaking, it is possible to distinguish between two types of blockchain developers, the core blockchain developer, and the blockchain software developer.

The core developer is responsible for the architecture and security of a blockchain system. Basically, he is responsible for:

    • designing the network architecture;
    • configuring the consensus protocols and security patterns of the network;
    • supervising the network.

The blockchain software developer uses the architecture and protocols designed by the core blockchain developer to build decentralized applications using blockchain technology (dApps). It is a varied qualification and closer to that of the web developer. As such it incorporates a number of separate roles that cannot be covered by a single individual. Its tasks may include:

    • the development of smart contracts;
    • the development of front-end design;
    • the development of the back-end related to the blockchain;
    • testing operations to verify the correct functioning of the dApp;
    • integration with other applications or services.

Having said this, and taking into account the existence of different types of blockchain, it is necessary to understand in which direction to set your specialization. Clearly, this also depends on other factors, related to the technical knowledge you possess and to your own goals: if, for example, you know how to use JavaScript, you have a minimum of experience in front-end development, and you want to learn how to develop smart contracts, you will probably aim to become a blockchain software developer by focusing your interest on Ethereum. On the contrary, if you have a good knowledge of Golang and Node.js and your goal is to become a core blockchain developer, then you will need to specialize in Hyperledger Fabric.

Before delving into the steps of becoming a blockchain developer, it’s important to note that there is some background knowledge you need to have, such as understanding programming languages and the theoretical and structural aspects of the chosen blockchain technology.

Usually, anyone who decides to become a blockchain developer is already a programmer. If you don’t have a background in programming, we strongly recommend that you attend a basic course to deepen your understanding of at least one programming language.

Consequently, if you want to gain a deeper understanding of blockchain development, it’s important to have knowledge of programming languages such as JavaScript, Bash, Golang, and Yaml for Hyperledger Fabric, as well as Solidity, Vyper, and Assembly for public EVM-compatible blockchains.

Moreover, to gain a thorough understanding of blockchain development, it’s crucial to study the theoretical and structural aspects of the chosen technology. For instance, in the case of Hyperledger Fabric, you should explore official documentation and focus on fundamental concepts such as channels, organizations, peers, orderers, and Certificate Authorities (CAs). You should also study the typologies and mechanisms for delivering and conserving certifications.

In Ethereum, on the other hand, you should concentrate on smart contract development by studying Solidity, the primary programming language used for this purpose. Although these technical and specific concepts may seem daunting, they are definitely learnable through self-study or by taking courses that offer certificates to verify your newfound skills.

Once you have this knowledge, you can move on to the steps.

Step 1: Understand the Basics of Blockchain Technology

To become a blockchain developer, it’s essential to understand the fundamentals of blockchain technology. But don’t worry, you don’t need to be a tech genius to get started! Begin by reading articles or watching videos that explain blockchain technology in simple terms. This will give you a solid foundation to build upon.

Step 2: Choose Your Blockchain Platform

There are several blockchain platforms available, such as Ethereum, Hyperledger, and Corda. Each platform has its own unique strengths and weaknesses, so pick the one that aligns with your goals and interests. For instance, if you’re interested in building decentralized applications, Ethereum is an excellent choice due to its robust smart contract functionality.

Step 3: Learn a Programming Language

Now that you’ve chosen your blockchain platform, it’s time to learn a programming language. The most common languages used in blockchain development are Solidity (for Ethereum) and Golang (for Hyperledger). These languages are relatively easy to learn, especially if you have prior programming experience.

Step 4: Set Up Your Development Environment

To start developing on a blockchain platform, you need to set up a development environment. This might sound daunting, but don’t worry, it’s not as complicated as it seems. You’ll need to install a blockchain client, such as Geth (Go) for Ethereum or Hyperledger Fabric for Hyperledger. There are plenty of tutorials available online to guide you through the setup process.

Step 5: Write and Deploy Smart Contracts

Smart contracts are at the core of blockchain technology. They’re self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code. Writing and deploying smart contracts is a critical step in blockchain development, as it enables the creation of decentralized applications.

Step 6: Build Decentralized Applications

You’ve got the basics down, so now it’s time to start building your first decentralized application! Don’t worry if you feel a bit intimidated – you don’t have to create the next big thing just yet. Start with a simple project, such as a decentralized voting application or a supply chain management system. This will give you valuable hands-on experience with building decentralized apps.

Step 7: Test and Deploy Your Application

Once you’ve built your application, it’s time to test it thoroughly to ensure it functions as intended. You’ll also need to deploy it to the blockchain network, which can be a bit tricky. But don’t fret – there are plenty of resources available online to help you through this process.

Step 8: Stay Up-to-Date with the Latest Developments

Finally, it’s essential to stay up-to-date with the latest developments in the field of blockchain technology. Attend conferences, read blockchain publications, and network with other blockchain developers to stay informed about the latest trends and best practices.

Blockchain technology is known to be quite intricate, not necessarily due to the technical proficiency required, but more so because of the extensive range of technology components that must be understood and implemented to create a functional blockchain solution, particularly within the Hyperledger Fabric ecosystem. Moreover, it is not easy to find an environment where one can freely practice notions and operations studied only at a theoretical level.

Depending on the level of programming knowledge previously possessed, we believe that a period between 4 and 6 six months is an acceptable timeframe to acquire the basic skills that will provide the opportunity to start a career within a company, as a junior blockchain developer.

AstraKode Blockchain (AKB) has been designed in part to meet this need – to give the possibility to put theoretical knowledge into practice and to speed up the process of developing blockchain solutions
