It isn’t as hard as it seems!

What is a Blockchain?

In very basic terms, a blockchain is a database with a few special properties. It is decentralized, and public and the data is stored in the form of blocks, connected together to form a chain. Hence the name, Blockchain. Each single data block is an immutable record of data, not owned by any single entity, but rather managed by a cluster of nodes on the network.


It was first brought to light by Bitcoin, although the scope for programming or development on the Bitcoin blockchain was limited. Blockchain is the technology that is used to process and record transactions on cryptocurrencies. Blockchain development really took off with the introduction of Ethereum, presenting to the world the first programmable blockchain. Ever since, blockchain development has evolved into a hot concept, with its popularity through the roof.

Blockchain development isn’t too dissimilar to regular programming, as further sections will present. The opportunity for an individual to create apps on top of a blockchain is as exciting as it sounds! Let’s see how to get on with it.

What Is Blockchain Development?

Blockchain development involves creating and maintaining decentralized applications and smart contracts on blockchain platforms like Ethereum. It requires programming skills, understanding of blockchain technology, and expertise in blockchain-specific languages and tools. Developers build secure and transparent applications that use the blockchain's distributed ledger to record and verify transactions and data.

What Does a Blockchain Developer Do?

A blockchain developer designs, builds, and maintains decentralized applications on blockchain platforms. Their tasks include writing code, creating decentralized systems, ensuring security, implementing consensus algorithms, and integrating blockchain technology into various projects. They also troubleshoot and optimize blockchain applications.

How Does One Become a Blockchain Developer?

The following are some of the steps of becoming a blockchain developer:-

  • Learn the Basics: Start by researching and understanding how blockchain technology works, key terminology, and the overall process.
  • Learn Programming: Learn programming languages like Solidity, Javascript, Python, or Go, as they are commonly used in blockchain development. Pick one and stick with it.
  • Understand Blockchain Processes: Try to focus on understanding the various processes involved. For example, if you want to build a wallet application, consider features like balance viewing and account details.
  • Blockchain Platforms: Choose a blockchain platform to specialize in, such as Ethereum, Binance Smart Chain, or others. Study their ecosystems and technologies.
  • Explore Blockchain Libraries: Explore available blockchain libraries and frameworks that can simplify development, like web3.js for Ethereum or ethers.js for Ethereum-compatible chains.
  • Advanced Topics: Dive into more advanced topics like consensus algorithms, security best practices, and scaling solutions.



Now, let's look at some technical skills required to become a blockchain developer.

Technical Skills Required to become a Blockchain Developer

The following are some of the key skills you should know in order to become a blockchain developer:-

  • Blockchain Fundamentals: In-depth understanding of blockchain technology, its principles, and how decentralized systems work.
  • Programming Languages: Proficiency in languages like Solidity (for Ethereum), JavaScript, Python, Go, or Rust.
  • Smart Contracts: Ability to design and develop smart contracts for various blockchain platforms.
  • Development Tools: Familiarity with blockchain development environments such as Remix, Truffle, and Hardhat.
  • Web3 Libraries: Knowledge of Web3.js, ethers.js, or other libraries for interacting with blockchain networks.
  • Blockchain Platforms: Expertise in specific blockchain platforms like Ethereum, Binance Smart Chain, or others.

What are the benefits of becoming a blockchain developer?

The following are the benefits of becoming a blockchain developer:-

  • High Demand: Blockchain technology is in high demand, and established companies and startups are looking for skilled blockchain developers.
  • Lucrative Career: Blockchain developers usually get competitive salaries due to their specialized skill set.
  • Innovation: You get to work on cutting-edge technology that has the potential to disrupt various industries, from finance to healthcare.
  • Decentralization: You contribute to developing decentralized systems that have transparency, security, and trust.
  • Diverse Opportunities: Blockchain is used in various sectors, which provides diverse job opportunities, from fintech to supply chain.

Top Programming Languages For Blockchain Development

  • C++. The oldest of them all, C++ still provides a great amount of functionality and features to assist blockchain development. Blockchain demands speed and security, and C++ with its superior memory control can help achieve those objectives. With multithreading, you can make sure that your blockchain application is able to handle multiple tasks at once. Being mature, C++ is constantly updated, with debuggers and analytical tools available to help you code better. All these advantages tie in beautifully with the fact that C++ is, and for a long time, will be a great choice for blockchain development.

  • Solidity. Moving on to a language that caters particularly to the blockchain, Solidity was actually developed by Ethereum. It utilizes C++’s object-oriented programming constructs, as well as JavaScript’s functions. The language itself is not very complicated, but having a grasp of other modern languages like Python makes it easier. It is the go-to language for developing smart contracts, or decentralized apps (dapps). For developers looking to add smart contract functionality to their ledgers, like Ethereum, Solidity is the way to go.

The core parts of a blockchain that you can try your hands on include smart contracts, decentralized apps, and ICOs (Initial Coin Offerings). Start slow, master a small section of blockchain development, and gradually move on to bigger and greater things. As you learn, you will be exposed to more programming languages like Solidity, one of them being GO. It makes sense to get familiar with these languages once you are comfortable with languages like Solidity.
