How to Become A Blockchain Developer A Full Guide

Blockchain Developer

You might be wondering if blockchain development is right for you if you’re reading this article. You might have no programming experience, or you may not be technologically savvy. It might seem overwhelming to start. How to Become a Blockchain Developer.

A few years ago, I felt the exact same way.

Although I was first learning blockchain technology as a child, I felt overwhelmed when I started to learn how to develop software. It was difficult for me to learn the first time. It was hard to learn at first. But, in retrospect, perseverance paid off eventually.

The same applies to blockchain development. Although it may seem overwhelming, once you understand the concepts I’ll be discussing in this article you’ll find some clarity.

Who is a Blockchain Developer?

A blockchain developer is someone who develops apps for the blockchain protocol armature. Their day-to-day work includes developing and optimizing algorithms that conform and run the Blockchain Protocol, a protocol that runs on top of the standard Internet Protocol (IP) that acts as the Internet for blockchain-powered bias. does.

There are two types:

1. Core Blockchain Developers

These developers are responsible for the development of the back-end (main engine), of Decentralized Application (Dapps). These include the Ethereum, Bitcoin, and Cardano Blockchains.

These developers often use C++, Go, and Haskell to write their code.

2. Blockchain Software Developers

They are responsible for creating and building Dapps’ front-end. These interfaces are the web and mobile interfaces users use to interact with Dapps. This category includes most blockchain developers.

They mostly use Javascript and Solidity programming languages to write code.

Let’s take an example to illustrate the difference between software developers and core developers of blockchain.

Web developers create web applications using web browsers. They don’t create web browsers. They build the web browsers (main engines) for this world’s “Mozillas”. Core blockchain developers create the browser (main blockchain network), while blockchain software developers build apps.

Which Blockchain should I use?

1. Bitcoin Blockchain

This is the distributed ledger that powers the Bitcoin cryptocurrency. This blockchain uses Proof of Work (PoW) as its consensus mechanism. This consensus mechanism has been a source of contention in recent years, as PoW consumes a lot of energy. has more information.

The Bitcoin blockchain has no other use than to power the cryptocurrency.

2. Ethereum Blockchain

The Ethereum blockchain is an open-source, decentralized smart contract platform. Its smart contract functionality, which allows Dapps to build on it, has made it one of the most popular blockchain platforms.

It currently uses PoW for its consensus mechanism, but it is aiming to replace PoW with Proof-of-Stake (PoS) due to the high energy use of PoW.

It is also the blockchain technology behind the popular cryptocurrency Ether (ETH).

3. Cardano Blockchain

It is an open-source, decentralized blockchain platform that uses Proof-of-Stake (PoS), as its consensus mechanism. It is the platform that powers Ada, a popular cryptocurrency.

Cardano, unlike the Ethereum blockchain, is developed using evidence-based methods and peer-reviewed research. The proposed methods must be subject to academic research before they can be implemented.

This blockchain technology uses the Haskell programming language, which is commonly used in banking and the financial industry.

Libraries and Frameworks for Blockchain Development

HTML3.js

This collection of libraries allows you to interact remotely with the Ethereum node using HTTP, Websocket, or IPC.

React.js

This open-source Javascript library allows programmers to create beautiful user interfaces. Any framework can be used.

Ethers.js

It’s a collection that lets you interact with the Ethereum blockchain.

Metamask

It’s a browser extension and cryptocurrency wallet that allows users to store, buy, and trade tokens on any blockchain.

Node.js

It’s a back-end JavaScript runtime environment that executes Javascript code outside of a web browser. Node.js is used by decentralized applications to interact with smart contracts or public nodes.

Ganache

It’s a library that developers can use to develop Ethereum blockchain applications. It allows developers to create, deploy, test, and monitor decentralized applications in a secure and deterministic environment, without having to interact with the main Ethereum Blockchain.

Which Programming Languages for Blockchain?

Solidity

This is the programming language used to create Ethereum smart contracts.

Javascript

It is used to create user interfaces.

Go, C++

These languages are used to create the back-ends for blockchain systems by the core developers of the blockchain.

Haskell

This programming language is used by core Blockchain developers to build the Cardano blockchain.

Notification

Solidity remains the preferred blockchain programming language for many developers. It is because of its large developer community. Solidity is the best choice unless you have a specific use case or are a core developer for blockchain.

Use cases for Blockchain

1. Finance

Cryptocurrencies

There are more than 5,000 cryptocurrencies today. This information is from CoinMarketCap which tracks cryptocurrency market caps, rankings, and prices. It also tracks exchange volumes, currency conversion, prices, and exchange volumes. The most popular cryptocurrencies are Bitcoin and Ethereum. Cardano is Polkadot is also in this space.

Many people believe that cryptocurrencies are the only use case for blockchain. However, this is incorrect. It is, however, the largest use case for blockchain.

You can launch and build a token as a blockchain developer. Crypto developers should also be able to create their own cryptocurrency. There is one catch. There are many cryptocurrencies and tokens available. It is important to create a token or cryptocurrency that solves real-world problems. It will be difficult to get traction and survive long-term.

Cardano’s Cardano Africa initiative is a good example. Their goal is to use Ada, the name of Cardano’s cryptocurrency, to solve financial problems in developing countries like access to loans and accessibility. This is a luxury that many people enjoy in the developed world.

It is important to remember that creating a cryptocurrency is difficult. This is due both to the large number of resources required and the distrust of potential users due to the reputation of Initial Coin Offerings.

Investors have been losing trust in ICOs due to a lack of transparency from the companies running them. Scams are also a frequent problem with ICOs. These scams have resulted in investors losing their money because they were not well informed.

It is crucial that developers understand the differences between tokens and coins when it comes to cryptocurrency. When talking about cryptocurrency, we use coins and tokens interchangeably.

A cryptocurrency coin can be classified as a store or exchange value. Bitcoin, for example, is a coin but not a token. It can be used as a store, or an exchange of value, just like a currency. Tokens are digital representations of assets that can be traded using the blockchain network. This category includes Ethereum and its ERC-20 tokens. Although the differences between them are not clear, they still exist.

Decentralized Finance (DeFi).

The adoption of DeFi in the blockchain world is on the rise. DeFi is designed to replace traditional financial systems. It basically takes financial products and transfers them to the blockchain ecosystem. These products can include trading, loans, savings, and loans.

Take a look at the DeFipulse 1-year chart. You will see how DeFi adoption has skyrocketed in the past few months.

Most DeFi currently runs on the Ethereum blockchain. Maker, Aave, and Compound are some of the most popular DeFi projects on the market. Maker, Aave, and Compound can be used as lending platforms. Polygon (Indian Blockchain) is used as a payment platform. Uniswap is used for decentralized exchange (DEX).

You should be ambitious enough as a developer of blockchain and techie to create such platforms.

2. Supply Chain

The supply chain system tracks the movement of goods and services from one source to another. It is used by large companies like Walmart to improve supply chain transparency. Blockchain technology can help ensure transparency and honesty in the supply chain by ensuring that all distributors are transparent.

3. Digital Identity

Cardano has partnered up with Atala Prism in order to allow the issuance of digital identities and credentials that users can control and share securely and privately. It is possible to build it on Cardano’s Blockchain without the need for third-party verification services.

They have recently signed a deal to provide digital identities for over 5 million students in Ethiopia. has more information about the deal. You can develop digital identity systems to secure digital IDs and certificates. Blockchain.

4. Healthcare

Blockchain can be used in healthcare to track patient and drug information, validate patient identities and make direct payments for healthcare services.

This article clearly explains how blockchain technology can be used to provide these services in healthcare. These are just a few uses for blockchain technology. It can be used to protect title deeds for real estate and to prevent tampering in democratic countries.

Wrapping Up

This article will explain how to become a blockchain developer, and take advantage of this lucrative career.

You should not assume that this niche isn’t for you, even though you might have some coding developer experience. Blockchain development can be learned over time, just like any skill. This guide is a good starting point. It is up to you to continue learning, practice, and improve. Practice makes perfect, as they say.
