# **Week 1 of Fitech Web3 BootCamp "What I learnt"**
## **-Web3 & Blockchain Technology-**

*I must start by saying the Fitech Bootcamp is an intensive one to learn and explore about Web3, and also other tech skills. You can join the community through [Twitter](https://x.com/Fitechcommunity) [Discord](https://discord.gg/VdR2awRN). Most importantly you can learn from the comfort of your home through virtual classes.*

## Introduction:
Starting by saying it was more of an eye opener more on **Web1** to **Web2** down to the new Web of technology and innovation called **Web3** which is an emerging technology of decentralization *- Powered by* : **Blockchain**.

Initially I thought it was only **Trading Cryptocurrencies**, **NFTs**, **Airdrops**, **Wallets** and **Decentralization** that exist in Web3 not knowing they are more to this technology than what I thought and know.

## Topics & Docs References by: (Mentor Manoah Luka)

We covered some topics and also from reading the [Ethereum Docs](https://ethereum.org/en/learn/).

"He started by explaining the stages of the Web"

### **Web1**:
So we can say Web1 is more like a Static Websites which is **Read-only** (Users can only read information but can't respond or contribute to the information passed).

### **Web2**:
Web2 is more Interactive and social which is **Read and Write** (Users can respond and also create their own contents) e.g Facebook, X, Instagram and lots more, but are centralized "*meaning it is controlled by one person or entity*". *[Reference Docs](https://ethereum.org/en/developers/docs/web2-vs-web3/)*

### **Web3**:
Web3 is more of decentralization and distributed data which is **Read, Write and Own** (Users own the internet) e.g DeFi, dApps and lots more, giving ownership and control over your data "*Transparency & Immutability*". *[Reference Docs](https://ethereum.org/en/developers/docs/web2-vs-web3/)*


## **What is Blockchain**:
Blockchain is a **decentralized**, distributed **digital ledger** that records **transaction** (data) across many computers also known as (**nodes**). which when data is recorded it cannot be changed. called ***Immutability***. *[Reference Docs](https://ethereum.org/en/developers/docs/blocks/)*

## **Some Blockchains we explored and exploring are:**
1. Bitcoin Blockchain - *[Reference Docs](https://bitcoin.org/bitcoin.pdf)*
2. Ethereum Blockchain - *[Reference Docs](https://ethereum.org/en/learn/)*
3. Xion Blockchain - *[Reference Docs](https://docs.starknet.io/)*
4. Starknet Blockchain - *[Reference Docs](https://docs.starknet.io/)*

## Key Concepts of the Blockchain includes:

| S/N | Names | Docs to Read |
|:---:| ---------------- | ------------ |
| 1 | Decentralization | [ Reference Docs](https://ethereum.org/en/web3/) |
| 2 | Transparency | [ Reference Docs](https://ethereum.org/en/payments/#transparency) |
| 3 | Immutability | [ Reference Docs](https://ethereum.org/en/web3/) |
| 4 | Consensus Mechanism| [ Reference Docs](https://ethereum.org/en/developers/docs/consensus-mechanisms) |
| 5 | Cryptography | [ Reference Docs](https://ethereum.org/en/community/research/#cryptography--zkp) |

## **What is Smart Contract**:
They are self executed computer programs stored on the blockchain that follows predefined conditions or logic to execute its code, which cannot be changed once created.. *[Reference Docs](https://ethereum.org/en/smart-contracts/)*

1. Blocks - [*Reference Docs*](https://ethereum.org/en/developers/docs/blocks/)
2. Nodes - [*Reference Docs*](https://ethereum.org/en/developers/docs/nodes-and-clients/)
3. More on Consensus Mechanism of Ethereum - [*Reference Docs*](https://ethereum.org/en/developers/docs/consensus-mechanisms/)
4. Ethereum Accounts - [*Reference Docs*](https://ethereum.org/en/developers/docs/accounts/)
5. Ethereum Wallets (MetaMask especially) - [*Reference Docs*](https://ethereum.org/en/wallets/find-wallet/)
6. Privates Keys and Seed Phrases
7. Transactions - [*Reference Docs*](https://ethereum.org/en/developers/docs/transactions/)
8. Ethereum Virtual Machine (EVM) - [*Reference Docs*](https://ethereum.org/en/developers/docs/evm/)
9. Gas and Types of Ethereum Gas - [*Reference Docs*](https://ethereum.org/en/developers/docs/gas/)
10. dApps and others - [*Reference Docs*](https://ethereum.org/en/developers/docs/dapps/)

## Summary
In all we learn about how Web3 is here to help us gain ownership over our own Data and Finance in a transparent and immutable way (Mostly from Bitcoin to Ethereum and other chains scaling).

I am now a better version of my yesterday from just knowing how to **Trade Cryptocurrencies**, **NFTs**, **Airdrops**, **Wallets** and **Decentralization** to becoming a Developer looking to build an innovative solution to a problem on-chain.
