Blockchain Developer Roadmap

Introduction

  • Overview of blockchain development career
  • Step-by-step guide to becoming a blockchain developer
  • Discusses job roles, education, skills, and salary expectations

What Do Blockchain Developers Do?

  • Create and maintain decentralized blockchain networks
  • Split into two main roles:
    • Core Blockchain Development: Focus on blockchain architecture and protocols
    • Blockchain Software Development: Build applications on top of blockchains (e.g., smart contracts, dApps)
  • Ensure seamless, secure, and efficient operations in the blockchain ecosystem

Blockchain Developer Education

  • No specific degree required, but a foundation in computer science or software engineering is helpful
  • Typical education includes a bachelor's degree with knowledge in:
    • Programming
    • Data Structures
    • Cryptography
  • Alternative pathways:
    • Specialized courses or bootcamps (e.g., Zero2Mastery, Coursera)
    • University extension programs
  • Advanced education options: Master's degrees in related fields

Must-Have Skills for Blockchain Developers

  1. Programming Languages: C++, Python, Solidity (especially important for smart contracts)
  2. Cryptography: Understand hashing, digital signatures, encryption algorithms
  3. Distributed Systems: Knowledge of peer-to-peer networks and consensus algorithms (e.g., proof-of-work, proof-of-stake)
  4. Smart Contracts: Familiarity with platforms like Ethereum, Hyperledger, Polkadot
