  • dApp Architecture: Understanding the frontend (Web3.js) and backend interaction with blockchain.
  • Web3.js & Ethers.js: Learn how to interact with smart contracts from the frontend.
  • IPFS and Decentralized Storage: Explore decentralized file storage and integration into dApps.
  • Practical:
    • Build a simple dApp (e.g., a voting or token-based system).
    • Use Web3.js to connect your dApp to a blockchain.
    • Integrate decentralized storage (e.g., IPFS) for dApp data.

Week 9–10: Blockchain Platforms & Use Cases

• Key Concepts: Exploring other blockchain platforms and their ecosystems.
• Study Topics:
  • Hyperledger: Learn about permissioned blockchains and Hyperledger Fabric.
  • Other Blockchains: Explore platforms like Polkadot, Binance Smart Chain, Solana, Cosmos, and Avalanche.

  • Practical:
    • Deploy a simple blockchain network using Hyperledger Fabric.
    • Explore use cases like NFT minting or creating custom tokens on Ethereum.

Week 11: Security, Auditing, and Scaling Solutions

• Key Concepts: Blockchain security, smart contract vulnerabilities, scalability.
• Study Topics:
  • Security: Common blockchain vulnerabilities, reentrancy attacks, overflow/underflow, front-running.
  • Smart Contract Auditing: Tools like Mythril, OpenZeppelin, and automated auditing.
  • Scaling Solutions: Layer 2 solutions (e.g., Polygon, Optimistic Rollup), sharding, sidechains.
  • Practical:
    • Audit your smart contract using tools like MythX.
    • Implement Layer 2 scaling on Ethereum with a sidechain (e.g., Polygon).

Week 12: Advanced Topics & Industry Trends

• Key Concepts: Emerging trends and advanced blockchain concepts.
