4. Blockchain
● Distributed ledger with lists of records (blocks) linked together.
● Operates on a peer-to-peer network.
● Every node (participant) has a copy of entire ledger.
● Once a transaction is recorded, it cannot be altered.

7. Ethereum
● Decentralized blockchain platform, enables development and
execution decentralized applications (DApps)
● Components:
○ Ethereum Blockchain
○ Ether (ETH)
○ Smart Contracts
○ Ethereum Virtual Machine (EVM)
○ Consensus Mechanism
○ Clients and Nodes:

9. Smart Contract
● Digital protocols on blockchain verify, control, and autonomously
execute agreements based on predefined rules.
● Types of Smart Contract :
○ Smart Legal Contracts: Enforceable, legal obligations with
consequences.
○ Decentralized Autonomous Organizations: Self-governing
blockchain communities with coded rules.
○ Application Logic Contracts: Synced code for cross-device
communication.

12. Tools needed

13. Nodejs
● Crucial for server-side logic in
Ethereum blockchain apps.
● Enables seamless integration of
JavaScript with Ethereum smart
contracts.
● Facilitates efficient communication
between frontend and Ethereum
blockchain.

14. Metamask
● Cryptocurrency wallet for secure
decentralized transactions.
● Enables seamless interaction with
Ethereum blockchain and Dapps.
● User-friendly interface and browser
extension.
● Link-The Ultimate Crypto Wallet for DeFi,
Web3 Apps, and NFTs | MetaMask

15. Truffle
● Development framework for Ethereum
blockchain applications.
● Automates testing, deployment, and
smart contract management.
● Facilitates efficient and streamlined
decentralized application development.
● Link-Truffle - Truffle Suite

16. Ganache
● Local blockchain emulator for
Ethereum development.
● Provides rapid testing and development
environment for Ethereum projects.
● Offers configurable options for network
simulation and smart contract testing.
● Link-Ganache - Truffle Suite

17. Setup
Development Env.

18. Setup Metamask for
local blockchain
● For metamask extension installation-Getting started
with MetaMask – MetaMask

19. Solidity
● High-level programming language for
Ethereum smart contracts.
● Syntax similar to JavaScript; designed
for smart contract development.
● Supports data types, functions, and
control structures for Ethereum.

21. Hello world program

22. Deploying Your First
Smart Contract

23. Interacting with Smart
Contract

24. DApps
● Decentralized application that operates on a blockchain network,
enabling peer-to-peer interactions without a central authority.
● How it works :
○ Smart Contracts: Self-executing code automates transactions
and agreements.
○ Blockchain Network: Decentralized ledger records all
transactions securely.
○ User Interaction: Users access DApps via interfaces, interacting
with smart contracts.
