Get started with web3 development on the blockchain today! ⛓

Here's a simple 5 minute guide to setup your metamask wallet and get free ethereum to develop decentralised applications 🧵
The first step is to head over to metamask.io/download, then download the metamask browser extention for your specific browser.

Chrome, FireFox and any chromium dervatives like brave, edge, vivaldi are supported.
After the extention is installed you'll be at the setup screen, click continue.
Click on 'Create a new wallet' and then agree on the next step.

This wallet is sort of like your bank account for all the cryptocurrencies and things that you own on the blockchain.
Create a password.

The password should be minimal 8 characters. Make it secure by adding numbers, special signs and capital letters.

You don't want hacker69420 to access your hard earned (mined?) doge :)
Now here comes the `Secret Recovery Phrase`, it is the key to your wallet. Make sure you save your Secret Recovery Phrase properly.

I'd reccomend writing it on a piece of paper, when I say store it properly, I mean it.

Anyone with this passphrase can access your wallet.
You will also be asked to confirm your Secret Recovery Phrase. You need to pick the exact order.

The Secret Rcovery Phrase is different from your private key, I'll show you how to access that soon.

But make sure you keep your private key, password and secret passphrase safe.
You can access the metamask dashboard by clicking on the extention icon in the top right corner, then click on the three dots and expand the view.

Now click on the three dots again, account details and you can now export your private key, do NOT share this with anyone.
This private key will be used in a lot of places while building dApps, keep it safe and use it properly.

Next let's get our free ethereum on the rinkeby testnet, this is 'fake' ETH for building and testing web3 apps on the blockchain.

twitter.com/intent/tweet?t….
Replace the 00x00... part with your public key and tweet it.

You'll find that in the metamask extention, click on the rectangle and it'll copy it straight to your clipboard.

This public is safe to share with anyone.
Finally you'll have to paste the link to the tweet you made on this website, the ETH funds will be transfered to your wallet on the testnet.

You make your own cryptocurrency on the blockchain with JavaScript in just these 9 lines of code.

Here's how it works🧵 Image
We'll be using thirdweb's JavaScript sdk to make this happen.

To start you'll need to setup Metamask and store your private key, here's a guide that'll take you through the entire process.

Next head over to thirdweb.com/start, you will be guided through a setup process.

These steps are to get your metamask setup with the thirdweb interface. Image

You can mint an NFT on the blockchain in JavaScript with ~10 lines of code.

No solidity, no testing... just these 10 lines of JavaScript.

Here's how it works 🧵
Typically minting an NFT would require you to write code in this language called 'solidity' to create a smart contract which would then mint the nft.

It require lots of testing, security checks and remember, once code goes on the blockchain it cannot be changed.

This sucks.
What we'll do instead is use the thirdweb's JavaScript library, and with 7 lines of code we'll mint NFTs without any hassle.

I'll guide you through the entire process, let's go 👇🏻

As I see it, there are three fundamental features of a blockchain:

🧊Decentralisation
🕵️‍♂️Transparency
🔐Immutability

They make the blockchain so powerful and useful.
1️⃣Decentralisation

All data is decentralised and not stored in some server at a billon dollar corporation.

Everyone gets to own the data.
2⃣ Transparency

Since everyone owns the data, it can viewed by everyone.

A lot of people think the blockchain keeps people anonymous, which is incorrect.

They are actually "pseudonymous".

Anonymous: not identifiable
Pseudonymous: identifiable under and alias

You wouldn't believe this, a friend of mine is earning $100k+ a year by writing code for something called a 'DAO'.

They are one of the most interesting applications of blockchain tech in web3 and are being used for a host of different things.

Here's how it works 🧵
🏢'DAOs short for (𝗗ecentralized 𝗔utonomous 𝗢rganizations) are an effective and safe way to work with like-minded folks around the globe.'

- Ethereum.​org

🔺Corporations of today operate with a 'hierarchical' structure so to speak.
The people at the top hold an immense amount of power, which they can use to their own advantage.

Granted there are laws and rules to prevent this, but they aren't always enforced.

There's always room for shady things like insider trading or manipulating the books to happen.

Want to learn Python as a beginner in 2021 for free?

Here's everything you need to know to get started with updated resources and a proper roadmap!

🧵 👇🏻
A bit of backstory, I wrote my first piece of Python code in 2015 but eventually gave it up for several years because of two main reasons:

A. I had no internet
B. No guidance

You have the power of the internet and I don't want the same to happen to you, hence this guide.
All of this is based on my experience of successfully teaching 300+ students the basics of how to code using Python.

Feel free to modify this roadmap to your liking!

Now onto the guide.
