Step 1: Learn a Programming Language

• Languages: Start with Python or JavaScript

  • Python: Easiest to learn, used in blockchain scripting
  • JavaScript: Used in frontend development and web3 frameworks

• Recommendation: Begin with Python; learn JavaScript later.

• Timeframe: Learn basics in 2 months.

Step 2: Version Control System (Git)

• Tool: Git (version control) and GitHub (platform hosting Git repositories)
• Purpose: Track code changes and collaborate with others
• Practice Requirement: 1 to 2 weeks of practice

Step 3: Data Structures and Algorithms

• Importance: Essential for efficient data processing and storage in blockchain development
• Key Data Structures: Arrays, linked lists, stacks, queues, etc.
• Timeframe: Study for 1 to 2 months

Step 4: Smart Contracts

• Language: Solidity (for Ethereum)

  • Use Remix IDE for initial coding and testing
  • Transition to Hardhat for professional development

• Project: Build small projects (e.g., basic token or NFT)

• Timeframe: 1 to 2 months

Step 5: DApp Development

• Concepts:

  • DApps: Decentralized applications using blockchain instead of traditional servers
  • Frontend Frameworks: React (most popular), Angular, or Vue

• Languages: JavaScript + TypeScript (preferred for React projects)

• Additional Tools: Web3 libraries such as web3.js or ethers.js

• Timeframe:

  • JavaScript + TypeScript: 2 months
  • React: Additional 1 to 2 months
