What Is a Blockchain?

What Is a Blockchain

First, let’s get on the same page about what blockchain is.

Simply put: blockchain is a digital ledger that provides a secure location for cryptocurrency transactions. 

Traditional databases arrange information in rows and columns to make it easy for computers to recognize the information.

Blockchain databases store this information in clusters or “blocks” with a limited capacity. Once each block is filled, it moves onto the next block.

Another key difference is that blockchain is decentralized so no particular entity can control or alter the information. Traditional databases can be altered or accessed by an administrator.

What Does a Blockchain Developer Do?

What Does Blockchain Developer Do

A blockchain developer designs and develops applications and systems based on blockchain technology. They program and design software systems using blockchain instead of traditional databases.

Blockchain is essential for businesses where sensitive data needs to be stored in a secure environment, such as cryptocurrency operations.

Since blockchain development requires a deep understanding of the unique technology, blockchain development is a specialized field which not every software developer is an expert in.

There are two main types of blockchain developers:

  1. Core blockchain developer: Core blockchain developers create and uphold the structure of blockchain systems. They create protocols, enhance security measures, and oversee the entire network's operations.
  2. Blockchain software developer: Blockchain developers build applications onto existing blockchain platforms. They’re responsible for both front-end and back-end development as well as design and maintenance.

When to Hire a Blockchain Developer

When to Hire Blockchain Developer

Here are some scenarios when you should consider hiring a blockchain developer:

  1. Adopting Blockchain for Business Processes: If your company is looking to integrate blockchain technology to enhance security, transparency, or efficiency in areas like supply chain management, financial transactions, or secure data management.
  2. Developing Decentralized Applications (DApps): For creating decentralized applications that operate on a blockchain network. This is used in industries like finance, gaming, or social media.
  3. Implementing Smart Contracts: If your business wants to automate agreements and processes using smart contracts, especially on platforms like Ethereum.
  4. Cryptocurrency Initiatives: For cryptocurrency-related projects, like launching a new cryptocurrency, developing crypto wallets, or integrating cryptocurrency payment systems.
  5. Enhancing Data Security and Integrity: Blockchain developers can provide solutions that significantly bolster data security and integrity.

What to Look for in a Blockchain Developer

What to Look for in Blockchain Developer

The right blockchain developer is extremely knowledgeable about the world of blockchain and what it can do but should also be a good communicator and able to work on a team.

Here are some things to look for when hiring a blockchain developer:

Blockchain Developer Skills

  • Understanding of Blockchain Technology: Deep knowledge of how blockchains work, including concepts like consensus algorithms, distributed ledger technology, and smart contracts.
  • Proficiency in Programming Languages: Familiarity with programming languages such as Solidity (for Ethereum), JavaScript, Python, Go, and C++ is crucial for developing blockchain applications like smart contracts.
  • Cryptography: Understanding cryptographic principles like hash functions, public-key cryptography, and digital signatures, which are fundamental to blockchain security. (You may recognize these as some of the same skills necessary for hiring an ETL developer.)
  • Experience with Data Structures: Knowledge of data structures (like Merkle trees, Patricia trees) is essential since blockchain relies heavily on complex data structuring.
  • Problem-Solving and Innovative Thinking: Blockchain development often involves novel and complex problems. The ability to think creatively and solve problems quickly is crucial in developing effective blockchain solutions and navigating the unique challenges that blockchain comes with.

Qualifications for a Blockchain Developer

Along with skills, your prospective blockchain developer needs to check a few boxes for experience and education.

Look out for these qualifications:

  • Educational Background: A bachelor’s degree in computer science, information technology, software engineering, or a related field of study is typically preferred. This provides developers with a solid foundation in key concepts relevant to blockchain technology.
  • Technical Proficiency: Knowledge of programming languages like Solidity (for Ethereum smart contracts), JavaScript, Python, Go, or C++. Understanding of blockchain fundamentals, including distributed ledger technology, consensus mechanisms, and smart contracts, is essential.
  • Practical Experience and Portfolio: Hands-on experience developing blockchain applications, DApps (Decentralized Applications), or smart contracts. A portfolio that showcases previous blockchain projects can show you that the blockchain developer has real-world experience in blockchain development.
  • Certifications in Blockchain Technology: Certifications from recognized institutions or online courses in blockchain technology can make a candidate more qualified. These certifications and classes will usually cover specific blockchain platforms, smart contract development, and the overall architecture of blockchain systems.
  • Understanding of Regulatory and Compliance Issues: Knowledge of the legal aspects and regulations on blockchain, especially in sectors like finance, healthcare, and supply chain. This includes understanding compliance issues, including data privacy, smart contracts, and cryptocurrency transactions.

Blockchain Developer Characteristics

Aside from technical knowledge and experience, there are a few soft skills that blockchain developers should possess.

  • Analytical Mindset: Blockchain developers need a strong analytical mindset to understand complex systems and solve challenging problems. They should be able to analyze requirements, understand how different parts of a blockchain interact, and foresee potential issues or bottlenecks.
  • Detail-Oriented: Attention to detail is essential in blockchain development. A small error in code can lead to big issues down the line, especially since blockchain transactions are irreversible. Developers need to meticulously review their code and understand the intricacies of the systems they work with.
  • Innovative Thinking: Blockchain is a relatively new and rapidly evolving field. Developers in this space should be innovative and open to exploring uncharted territories, experimenting with new ideas, and finding creative solutions to challenges.
  • Team Player: Blockchain projects often involve teamwork, with people contributing different skills and perspectives. A good blockchain developer is collaborative and can work effectively in a team environment, communicating ideas clearly and listening to others.
  • Adaptability and Continuous Learning: The blockchain landscape is constantly changing with new technologies, tools, and best practices. Developers should be adaptable, willing to learn, and stay updated with the latest advancements.
