1. Introduction to Blockchain
  • What is Blockchain?
  • Blockchain is a decentralized, immutable ledger used to record transactions securely across multiple nodes.
  • How does Blockchain work?
  • It works by chaining blocks of data that are verified through consensus algorithms, making it secure and tamper-resistant.
  • Difference between Blockchain and Traditional Databases:
  • Blockchain is decentralized, append-only, and tamper-proof, whereas traditional databases are centralized and allow CRUD (Create, Read, Update, Delete) operations.
  • What is cryptography?
  • Cryptography is the practice of securing data using algorithms to encode (encrypt) and decode (decrypt) information.
  • How is security ensured in Blockchain?
  • Security is ensured through cryptographic hashing, consensus mechanisms (e.g., Proof of Work), and decentralized nodes preventing single-point failures.
  • Understanding Public and Private Keys:
  • A public key is shared for receiving data, while a private key is kept secret for signing and accessing data, ensuring secure transactions.
  • What are Smart Contracts?
  • Smart Contracts are self-executing programs stored on the blockchain, enforcing terms and conditions automatically.
  • How do Smart Contracts work?
  • They execute when predefined conditions are met, removing intermediaries in processes like payments or asset transfers.
  • Writing your first Smart Contract using Solidity:
  • Use the Solidity programming language to define the contract, including variables, functions, and events, and deploy it to a blockchain like Ethereum.
  • Differences between Ethereum, Tron, Binance Smart Chain, and Polygon:
  • Ethereum: Pioneer with extensive DApp support.
  • Tron: Focuses on high-speed, low-cost transactions.
  • Binance Smart Chain: Low fees and high compatibility with Ethereum.
  • Polygon: Scalable and Ethereum-compatible Layer 2 solution.
  • Which platform is suitable for different projects?
  • Choose Ethereum for secure and complex apps, Polygon for scalability, Tron for entertainment DApps, and BSC for DeFi projects.
  • How to choose the right platform for your DApp?
  • Consider transaction costs, speed, developer tools, and community support.
  • How to build Decentralized Applications?
  • Build a frontend (e.g., React), a smart contract backend (e.g., Solidity), and connect them using libraries like web3.js or ethers.js
  • Understanding frontend and backend integration with Blockchain:
  • Use APIs or libraries like web3.js to connect your frontend to smart contracts deployed on the blockchain.
  • Deploying your first DApp:
  • Deploy the smart contract on a test network (e.g., Rinkeby for Ethereum) and connect it with your frontend.
  • What is an Initial Coin Offering (ICO)?
  • An ICO is a fundraising method where tokens are sold to investors in exchange for capital to develop a project.
  • How to create and launch your own ICO?
  • Create a token (e.g., ERC-20), set up a distribution model, and deploy it on a blockchain like Ethereum.
  • Understanding the regulatory landscape of ICOs:
  • Regulations vary by country; ensure compliance with securities laws and anti-money laundering (AML) policies.
  • What is a Crypto Wallet?
  • A crypto wallet stores private and public keys, allowing users to send, receive, and manage cryptocurrency.
  • How to use different wallets like MetaMask, Trust Wallet, Phantom, and Ledger?
  • MetaMask: Browser extension for Ethereum and compatible networks.
  • Trust Wallet: Mobile wallet supporting multiple blockchains.
  • Phantom: Wallet for Solana-based applications.
  • Ledger: Hardware wallet for secure, offline storage.
  • Wallet integration across blockchains:
  • Use blockchain-specific APIs (e.g., Ethereum's web3.js) or SDKs to integrate wallets into your app.
  • Best practices for managing and securing your wallet:
  • Use hardware wallets for large holdings.
  • Never share private keys.
  • Enable two-factor authentication where possible.
