Once an emerging tech, the blockchain market size is projected to increase to $943 billion by 2032.

Blockchain developers design, code, test, and deploy blockchain-based applications. They have specific job descriptions and responsibilities. Blockchain developers need specific skills and competencies. Let’s discuss this step by step.

What is a blockchain developer: job description

Blockchain developers study the requirements of an organization, and they design a blockchain-based solution. They design the blockchain network and applications. Blockchain developers code and test the applications. Many experienced blockchain developers perform blockchain code reviews. After reviews and testing, blockchain developers deploy the blockchain network and applications.

Responsibilities of a blockchain developer

Blockchain developers typically have the following responsibilities:

• Analyzing the organizational requirements;
• Determining the appropriate blockchain development approach, e.g., public vs private blockchain;
• Choosing the appropriate blockchain development platform, e.g., Ethereum;
• Designing blockchain applications;
• Documenting technical solutions;
• Coding blockchain applications;
• Analyzing and resolving bugs and action items arising out of code reviews;
• Testing blockchain applications;
• Deploying blockchain apps;
• Maintaining blockchain applications;
• Reporting the status of blockchain development projects;

Public blockchain development skills

Blockchain developers might need skills in platforms like Ethereum, Polkadot, and BNB Smart Chain. Ethereum is the most popular among them. Ethereum blockchain developers need the following:

• Familiarity with EVM (Ethereum Virtual Machine), the development platform on the Ethereum blockchain;
• Languages like Solidity or Vyper for developing Ethereum smart contracts;
• Experience in developing Ethereum DApps (Decentralized Apps);
• Experience in Ethereum blockchain development tools like Web3.js, Truffle suite of tools, and the Remix IDE;
• Familiarity with test blockchain networks like Sepolia;
• Knowledge of scaling Ethereum DApps.

Enterprise blockchain development skills

Depending on the choice of Enterprise blockchain framework, blockchain developers might need to know Hyperledger Fabric, R3 Corda, or ConsenSys Quorum. The skills vary accordingly.

Hyperledger Fabric developers need to know any one of Java, JavaScript, Node.js, or Golang for blockchain development. R3 Corda blockchain developers need to know JVM (Java Virtual Machine)-compatible languages like Java or Kotlin. ConsenSys Quorum is based on Ethereum, therefore, developers need Solidity skills.

Software engineering and software development process skills

Blockchain developers need a sound knowledge of the following:

• Software development methodologies and lifecycle models;
• Software architecture;
• UI design principles;
• Code review;
• Testing and DevOps processes, methods, and tools.

Competencies

Blockchain developers need the following competencies:

• Passion for excellence;
• Commitment to the project requirements;
• An ability to understand the perspective of end-users;
• Communication skills;
• Collaboration;
• Teamwork;
• An ability to see the bigger picture.
