⚡ Smart Summary
Blockchain developer careers center on building decentralized applications, smart contracts, and secure distributed systems. This page explains the role, the core skills, the education routes, realistic salary expectations, certifications, and a practical pathway to land your first job.
Who is a Blockchain Developer?
A Blockchain developer develops and enhances blockchain-related applications, commonly known as decentralized applications or DApps. They are also equipped to develop and enhance smart contracts, blockchain architecture, and blockchain protocols.
A blockchain developer also secures digital transactions by creating systems and applications to record and store blockchain data. These professionals are also responsible for preventing external changes to those transactions and any hacks that might compromise the security of those transactions.
Types of Blockchain Developers
There are two types of blockchain developers. One type creates the underlying technology, while the other builds on top of that creation. Below are more details on each role.
Core Blockchain Developers
A core blockchain developer develops blockchain architecture. This role is trained to run a successful blockchain solution by designing specific protocols that produce the desired outcomes.
Beyond this, core blockchain developers also make high-level decisions that shape the development of blockchain-related applications.
Example: Ethereum, which is a Layer 1 Blockchain.
Blockchain Software Developers
Blockchain software developers implement and maintain a blockchain system that has already been designed and solved by the core blockchain developer.
Example: Sandbox, which is built on Ethereum.
At the start of your blockchain developer career, you are most likely to fall into the latter category. Blockchain software developers are the most common professional breed.
Skills Needed to Become a Blockchain Developer
A blockchain developer needs to understand blockchain technology, its architecture, how it works, and the critical concepts associated with blockchain development, such as hash functions, distributed ledger technology, and consensus protocols. The required knowledge covers three basic spheres, each as important as the other.
Cryptography
A blockchain developer keeps data secure by using hashing and encryption. Encryption protects data on a blockchain at a surface level, while its internal protection is provided by hashing.
A blockchain developer needs to be competent and comfortable with symmetric and asymmetric cryptography. These methods use unique series of numbers and letters to facilitate transactions between two parties interacting within the blockchain system.
Sometimes that involves using the same code or password for both parties, and sometimes it involves using two different codes, each of which requires the other for the transaction to be completed.
A blockchain developer needs to understand hashing because it ultimately makes it nearly impossible to penetrate data within the blockchain system. Hashing is a professional-level coding technique that makes blockchain text almost impossible to read without the correct mathematical algorithm.
Data Structures
A blockchain developer must know how to operate a back-linked record of data transactions within the Blockchain. Understanding data structures for Blockchain serves two functions.
- The first is to make the Blockchain immutable.
- The second is to make the Blockchain efficient for those who either develop or use it.
Invariably, data structures include linked lists, binary trees, heaps, hashing, and graphs. Blockchain developers must understand how to store these data structures as flat files and simple databases.
The ability to work with data structures is an extension of understanding cryptography. One knowledge set cannot go without the other.
Smart Contracts
Smart contracts are mostly associated with the Ethereum blockchain technology, which pioneered this skill and technique. Smart contracts reduce costs, red tape, and risk. While Ethereum is a pioneer here, other blockchain platforms are becoming increasingly reliant on people with this set of skills.
You will need a solid knowledge of smart contracts when training to become a blockchain developer.
How to Become a Blockchain Developer?
Now that the required skills are clear, here are the practical steps that help you become a Blockchain Developer.
Step 1) Learn how the blockchain process works
Blockchain is an intricate process that is well explained in white papers produced by crypto companies that use Blockchain, such as Bitcoin, Ethereum, and Litecoin. Understanding the basic structure of a blockchain and what it seeks to do is essential for your blockchain developer pathway.
Step 2) Learn how digital currencies work
While blockchain is not designed explicitly for cryptocurrencies, working with cryptocurrencies is the ideal platform to develop the skills required to do this work.
Step 3) Learn to code
Next, you need to learn to code. Various coding languages have a specific purpose, so you should have a clear idea of what you need to code for before signing up for a coding boot camp, certificate program, or associate degree program.
Step 4) Learn about smart contracts
Smart contracts are an increasingly important component of Blockchain. Regardless of the platform you choose to work with, if you do not understand how smart contracts work, you will have difficulty succeeding as a blockchain developer.
Step 5) Keep practicing and learning
Blockchain development constantly expands, and coding and programming languages constantly evolve. The only way for a blockchain developer to stay ahead is by remaining at the forefront of that evolution.
Step 6) Apply for jobs
Once you have created your portfolio, it is time to apply for jobs. You can apply online, in person, through referrals, or through personal networking.
Step 7) Land the job
After completing all the steps and selecting the right role, you have moved from zero to a highly paid blockchain developer.
