Do you want to earn $120K+ as a junior blockchain developer in just 6–12 months? If so, read on, because the steps below will help you gradually become an expert in the field of blockchain development.
What is Blockchain Development?
Blockchain development creates decentralized applications (DApps) and blockchain networks using data base technology superior to traditional systems. A blockchain is a decentralized digital ledger that records transactions across thousands of computers worldwide, structured to make alterations nearly impossible. This blockchain technology enhances security, accelerates information exchange, reduces costs, and boosts transparency while eliminating intermediaries like banks or notaries that traditionally provided trust verification.
Moreover, blockchain’s significance has drawn widespread interest from organizations across industries, with banking leading adoption. It has sparked thousands of new jobs and startups, spanning mobile payments to healthcare solutions.
Types of Blockchain

Blockchain comes in four main types, each designed for different needs, from open crypto networks to private business systems. Here’s a simple breakdown to help you pick the right one for your project.
- Public Blockchain
- Private Blockchain
- Consortium (Federated) Blockchain
- Hybrid Blockchain
1. Public Blockchain
Public blockchain is where anyone can join, view transactions, and validate blocks. Think Bitcoin or Ethereum, which are fully decentralized and transparent, using consensus like Proof-of-Work (PoW) or Proof-of-Stake (PoS).
Pros: Maximum security, no central control, global access.
Cons: Slow speeds, high energy use, and public visibility of all data.
Best for: Cryptocurrencies, DeFi, public dApps.
2. Private Blockchain
Private blockchain development controlled by one organization with restricted access, where only approved users can read/write data. Like Hyperledger Fabric for internal company use.
Pros: Fast transactions, high privacy, easy compliance.
Cons: Less decentralized, relies on the controlling entity.
Best for: Enterprise operations, internal records, banking backends.
3. Consortium (Federated) Blockchain
Multiple organizations collaborate, sharing control across a group (e.g., banks in R3 Corda). Pre-selected nodes validate transactions.
Pros: Balanced decentralization, efficient for partners, customizable permissions.
Cons: Complex governance among members.
Best for: Supply chain tracking, cross-company finance, healthcare data sharing.
4. Hybrid Blockchain
Combines public and private features, some data public, some permissioned. Dragonchain or XinFin examples let companies control sensitive info while tapping public security.
Pros: Flexible privacy, scalability, and regulatory compliance.
Cons: Risk of centralization in private parts.
Best for: Government records, tokenized assets, enterprise Web3 pilots.
After getting a basic introduction to blockchain app development and its types. Let’s read what a blockchain developer is
Who is a Blockchain Developer?
A blockchain developer is a software engineer who designs, builds, and maintains decentralized applications (DApps), smart contracts, core blockchain protocols, and blockchain-based solutions. They focused on secure, transparent, peer-to-peer systems rather than centralized ones.
Unlike traditional developers who work with centralized servers (like AWS or Google Cloud), blockchain developers work with distributed ledgers where data is stored across thousands of computers globally, making it nearly impossible to hack or alter. Moreover, these developers work with cryptography, consensus mechanisms, and distributed ledger technology to create immutable, tamper-proof digital solutions.
Types of Blockchain Developers

There are two main types of blockchain developers.
- Blockchain Core Developers
- Blockchain Software Developers
1. Blockchain Core Developer
These types of developers focus on design and implementation of core blockchain protocols and consensus mechanisms, as well as cryptography and security patterns, for systems like Ethereum or custom chains. They are expert in:
They design the fundamental framework of a blockchain. Moreover, they craft algorithms like proof of work (PoW), proof of stake (PoS), or proof of history (PoH). They ensure that their blockchain software development is tamper-proof and resistant to cyber attacks. In short, these professionals ensure network scalability, reliability, and low-level optimizations
2. Blockchain Software Developers
Software developers build decentralized applications dApps and smart contracts that run on existing blockchains. They apply languages like Solidity or Rust to build user-facing blockchain solutions such as DeFi tools or NFTs. They are expert in:
These types of developers develop dApps that operate on decentralized blockchain networks. Additionally, they write smart contracts to handle things like NFTs or DeFi. They develop and integrate the user interface with blockchain-based backend systems. In a nutshell, their work emphasizes application logic, testing, and interoperability with protocols designed by core developers.
What Does a Blockchain Developer Do?

Most blockchain developers fall into two categories: Core Developers (who build the network itself) and dApp Developers (who build applications on top of the network).
1. Designing Blockchain Protocols
Core developers create the “rules” of the network. In particular, they design consensus mechanisms, which are math-based systems, such as Proof of Stake. As a result, these mechanisms allow thousands of computers to agree on a transaction securely and without relying on a central authority.
2. Writing and Auditing Smart Contracts
This is the most common task. A developer writes self-executing code (often in Solidity or Rust) that automatically moves funds or data when specific conditions are met.
In 2026, developers will spend a huge portion of their time on Security Auditing. Since a single bug can lead to millions of dollars in losses, they use AI automation tools and manual “war games” to find vulnerabilities before the code goes live.
3. Building Decentralized Applications (dApps)
Developers create the front-end websites and mobile apps that users interact with. To do this effectively, they must ensure these applications can “talk” to the blockchain by using libraries such as Ethers.js. As a result, users can connect their crypto wallets, for example, MetaMask, directly to the service.
4. Implementing Advanced Cryptography
Modern developers also integrate Zero-Knowledge Proofs (ZKP). In other words, this technology allows a user to prove something is true, for example, “I am over 18,” without revealing the actual data, such as their birthdate. Consequently, ZKPs are essential for the privacy-focused Web3 of 2026.
How To Become a Blockchain Developer: Step-By-Step Guide
