However, the tech world is still searching for answers to questions like how to start learning Blockchain development, how long does it take to become a Blockchain developer, which is the best Blockchain Course, which is the best Blockchain development language, etc. So, in this article, we provide you the perfect Blockchain developer roadmap for you to learn about concepts like cryptocurrencies, ledgers, crypto mining, data security using Blockchain, smart contracts and much more to land your dream job.

Who are Blockchain developers?

Blockchain technology deals with distributed databases called ledgers that maintain accurate and immutable records of every single transaction done across the computer systems that are part of a network. Blockchain developers are tech professionals who work in Blockchain technology and perform various tasks such as building smart contracts, designing database protocols, etc. They are broadly classified into two types: Blockchain Software Developer and Core Blockchain Developer

  • Blockchain software developer

Develop the front end and back end of dApps (decentralized applications)

Develop smart contracts and ensure their implementation

Develop APIs for blockchain integration

  • Core Blockchain developer

Design & monitor the network architecture

Implement different Blockchain features & functionality

Design Blockchain protocols along with consensus protocols.

Steps to get started with Blockchain development?

Now that you know the fundamentals of Blockchain development and the important roles in Blockchain technology, let us look at the steps to get started with Blockchain development

1. Learn the fundamentals and earn credentials

The best way to start out in Blockchain is by having a Bachelor’s or Master’s degree in Computer Science / IT as they will help you to understand the fundamentals easily. However, this is not compulsory anymore. Because apart from the degree programs, there are several recommended Bootcamps, online training programs, etc., to give you exposure to the particular technology.

2. Master the necessary Tech Skills

As it stands today, it is impossible to become a Blockchain expert without some minimal technical skills. Let’s take a brief glance at what some of these tech skills are:

Data Structures: You’re required to possess good command over Data Structure, including linked lists, binary trees, hashing, heap, graphs, etc., as they are regularly used by Blockchain Developers to develop immutable and efficient systems.

Programming Languages: Along with the Data structures, you would also require to know programming concepts (particularly OOPs concepts) to work as a Blockchain Developer. Suitable programming languages may be Java, C++, Python, etc.

Databases & Networking: Fundamental knowledge of Databases & Networking concepts like distributed systems will help you kickstart your journey as a Blockchain Developer easily.

Cryptography: Cryptography is a must-have technical skill to become a Blockchain Developer. You must learn various Cryptographic concepts such as hash functions, digital signatures, RSA algorithm, etc., to lay your foundation for a Blockchain Development career.

Additionally, you must be familiar with the web designing and development process, which are some of the core aspects of Blockchain Development.

3. Understand the Blockchain fundamentals

After learning the prerequisite tech skills, you need to know about the intricate details of blockchain technology such as its working, applications, etc. A sound knowledge of Blockchain architecture and understanding of the concepts like Hash functions, Consensus, Distributed ledger technology, etc., along with knowledge of Bitcoin, public and private approaches, and Decentralization, may prove to be crucial. You can learn them using various online and offline resources like tutorials, journals, training sessions, etc.

4. Understand Cryptonomics

Crytponomics is concerned with understanding the economical concepts and methodologies driving cryptocurrencies. It includes various crucial concepts such as transaction fees, transaction lifecycle using Bitcoin, mining, etc.

5. Learn about Ethereum and other DApps

Ethereum is the most popular open-source decentralized Blockchain network used for running smart protocols. It allows the development of Smart Contracts & Distributed Applications (DApps), avoiding usual issues like downtime, third-party interference, and fraud.

6. Understand Smart Contracts & Solidity

Smart Contracts are concerned with the protocols or instructions used for automation purposes with no third-party interference in the transaction event. Solidity is a statically typed, high-level language in which smart contracts are typically written. It is majorly based on JavaScript. Vyper and Simplicity are two other languages used to write smart contracts.

7. Get Hands-On Experience  

Finally, implement all your theoretical learning in the practical world and gain more exposure to become more proficient with the particular technology tools & platforms. Write smart contracts, develop your own Dapps, etc. Apply for various internship or training programs in Blockchain development to find more resources and a learning environment. Another option is to get certifications like IBM Blockchain Certification or Certified Blockchain Solution Architect (CBSA) to showcase your Blockchain proficiency to employers.

Books can also be reliable resources in learning Blockchain. Some notable books are:

  • The Book of Satoshi by Phil Champagne
  • The Blockchain Developer by Elad Elrom
  • The Basics of Bitcoins & Blockchains by Antony Lewis
  • Blockchain Revolution by Don and Alex Tapscott

Final words

So, now you have a complete roadmap to follow in your Blockchain Developer journey. Remember that the career path of a Blockchain Professional is not easy. However, considering the rapid growth of Blockchain Technology, your efforts will be well worth it.
