What the session is about

Introduction to the programmable capabilities of Ethereum blockchain
We'll be learning the basics and building a barebones application to interact with the blockchain
Two parts:
- Part1: Discussion on the building blocks of Ethereum
- Part2: Interacting with Ethereum

Prerequisites

Familiarity with Javascript, Node, HTML, and the console.

Part 1

Brief discussion:

Building blocks of Ethereum

What is full-stack?

Web2.0

Web3.0

Ethereum

Nodes ?

Nodes comprise of data, EVM, and 'World State'

World State

Simply put, mapping between 'addresses' and 'account states'
What is included in an 'account state'?
nonce,
balance,
storageRoot,
codeHash
Two types of accounts: Externally owned account, Contract account

Transactions

single cryptographically signed instruction
Two types:
- result in a message call
- result in creation of new account with associated code

Transactions comprise of:

```
{
    from: 
    to:
    value:
    gas: 
    gasPrice:
    data: ""
    nonce:
}
```

Quick Recap

Ethereum: 'world-computer'
Nodes: the computer systems that form the network that is ethereum
EVM: a tiny little computer inside a node, running 'bytecode'
Accounts: transaction creators and receivers. Two types(EOA, contract)
World State: mapping from address to state
Transactions: a single signed instruction

Part 2: Let's start building

What we'll be using

Solidity
A simulated Blockchain on our PC
HTML, Javascript

What we'll be building

Before we start

Clone the repository and install dependencies:

$ git clone https://github.com/nglglhtr/getter-setter
$ cd getter-setter
$ npm install

Recap

🎉 And that's it!

✅ Wrap up

What we covered

What is full-stack in Web3
Writing a smart contract
Tools that we can use
- To compile our contract, solc
- To run a local blockchain, ganache-cli
- To interact with blockchain Node and npm
