Blockchain Developer Roadmap

With the rising security concerns, decentralized systems are gaining a lot of popularity. This makes the job of a blockchain developer very desirable. However, it can be challenging to find an efficient roadmap to practice and improve the right skill set. This tutorial will provide you with an efficient blockchain developer roadmap so that you can focus purely on what is needed to become a desired blockchain developer.

Being a developer myself, I know how hard it can be to figure out exactly what to learn on the journey of becoming a blockchain developer. So let me give you a basic roadmap to become a blockchain developer which will not waste any time learning useless skills.

What is Blockchain?

Now, before I actually explain how a roadmap for blockchain development actually looks, you first need to understand what a blockchain is. In plain words, a blockchain is a decentralized record of information. The data is not stored in one place, though; it is divided and then distributed over a network of computers. It comprised blocks of information linked together in a chain using cryptographical techniques. Each block contains a time stamp, transaction data, and the previous block's cryptographic hash. This forms a chronological and immutable record of transactions.

To explain it in simple words, let me give you a real-life example. Say you have a hundred dollars. If you wanted to implement a blockchain architecture to store your money, you would distribute the money amongst your friends. For example, you could ask each of your 100 friends to keep 1 dollar with them and instruct them only to give you back the money if you tell them a password. This is called a decentralized system, meaning all your money is not deposited in one place but distributed across multiple places. This increases security. If a thief intended to steal all of your money, they would struggle to figure out all a hundred unique passwords.

Blockchain Developer Roadmap from Scratch

Now that you know what a blockchain is, let us get you started with the journey of how to become a blockchain developer. Here I have discussed the necessary steps in an efficient blockchain roadmap for beginners.

Foundational knowledge

• Starting from the basics is the first step in the blockchain developer roadmap. Understand the fundamentals of block technology. These include concepts like distributed ledger, consensus method, cryptography hash, and public or private key encryption.
• Learn about the types of blockchains (public, private, and consortium), their applications, advantages, and limitations.
• Study the history of successful blockchain projects. This includes studying projects like Bitcoin, Ethereum, and more. This will give you insights about modern industry standards and why they are used in the first place.
  

Programming languages and tools for blockchain development

• Firstly, figure out your goals. Ask yourself what kind of projects you want to work on. The project you want to work on might require learning different skills. 
• For example, if you want to work with Ethereum, you should learn Solidity. 
• On the other hand, if you want to work with Bitcoin, you should learn C++ or Rust. 
• If you want to work with frameworks like Hyperledger Fabric and Corda ya should learn Java, Go, and JavaScript. 
• Also, consider learning different blockchain development tools and libraries like Truffle, Web3.js, Remix, and Ganache.
  

Blockchain platforms

Learn the different popular blockchain platforms and protocols.

• Ethereum: Learn the architecture used in Ethereum, including the Ethereum Virtual Machine (EVM), Gas, and ERC token and smart contract standards.
• Hyperledger Fabric: Learn about the permissioned blockchains, channels, smart contracts (also known as chaincode), and Fabric SDKs.
• Learn additional platforms that are required in your project. This includes platforms like Corda, EOS, and Tezos.
  

Smart contract development

• Start by studying smart contract development best practices, industry standards, security considerations, and common vulnerabilities (for example reentrancy, integer overflow).
• Practice by writing, deploying, testing, and developing your own smart contracts. Use development environments like Remix, TruffleSuit, or VS code. Add the appropriate extensions required by your project.
• After you are comfortable with the basics, Learn about advanced topics like state channels, off-chain computations, and oracles to improve smart contract interactivity and scalability.
  

Decentralized applications or DApps

• Learn how to develop frontend interfaces (UI/UX) for decentralized applications with web development frameworks such as React, Angular, and Vue.js.
• Then integrate smart contracts with frontend applications that use Web3.js or other blockchain tools. This is for the interaction with the blockchain network.
• Then move on to develop full-stack DApps with backend logic for transaction processing, data storage, and user authentication.
  

Security

• Proceed to improve your understanding of blockchain security ideas, cryptographic primitives, and secure coding techniques.
• Then learn to use tools such as MythX, Securify, or OpenZeppelin Defender to perform code audits, vulnerability assessments, and penetration testing on smart contracts and blockchain apps.
• Stay informed and updated about security warnings, bug bounty programs, and community-led activities to improve blockchain security. The technology is still new and is advancing at a very fast rate.
  

Continuous learning and keeping up

It is a must to keep on learning and be updated to be a successful blockchain developer. The industry changes very fast as new platforms, tools, and practices are developed all the time. Keeping up to date enables developers to be on top of the game, flexible, and to make use of the newest discoveries in order to achieve the best results.

Why Should You Become a Blockchain Developer

There are a lot of advantages to becoming a blockchain developer by following this core blockchain developer roadmap. Here I have listed some of the advantages.
