Day 1: Introduction to Blockchain

Lets start Our Journey to Lean Blockchain concepts

Session 1: Understanding Blockchain Basics

What is Blockchain?
- Explanation: Blockchain is like a digital record book where information is stored securely. It's a chain of blocks, and once something is added, it stays there forever.
- Local Example: Imagine a community meeting where decisions are recorded in a book, and each new decision is added to the previous one, forming a chain.
Key Concepts: Blocks, Transactions, Decentralization
- Explanation: Blocks store information, like transactions in a market. Transactions are actions recorded in the blockchain, and decentralization means nobody controls it.
- Local Example: In a market, transactions (buying, selling) are recorded, just like actions recorded in a blockchain.
The Role of Consensus Mechanisms (e.g., Proof of Work, Proof of Stake)
- Explanation: Consensus mechanisms are rules ensuring everyone agrees on what's added to the blockchain. For example, 'Proof of Work' involves solving puzzles.
- Local Example: It's like a dance competition where everyone must agree on the winner before it's announced.
POS
Types of Blockchains: Public, Private, Consortium
- Explanation: Public blockchains are open to everyone, like a community notice board. Private blockchains are like a closed meeting among friends, and consortium blockchains are joint projects.
- Local Example: Imagine a notice board in a market where everyone can see announcements (public blockchain).

Setting up MetaMask
- Explanation: MetaMask is like a wallet for digital money (cryptocurrency). It's a way to store and use digital currency.
- Local Example: Just like carrying a wallet for Malawian Kwacha, MetaMask is a digital wallet for cryptocurrency.
Setting up Remix IDE
- Explanation: Remix IDE is a tool to write and test blockchain code (smart contracts).
- Local Example: It's like a notebook where you write down and test ideas before implementing them.

Introduction to Smart Contracts
- Explanation: Smart contracts are digital contracts stored on the blockchain, automatically executing when conditions are met.
- Local Example: It's like an agreement written and stored digitally, ensuring everyone follows the rules.
