Where to start?

When we want to begin something new, we need some direction to avoid getting stuck at the very beginning.

But we are all different and have unique ways of learning.

This thread is based on my experience, and it helped me a lot in learning Web3.

Roadmap

I'm not too fond of roadmaps, but reading one can give us an idea of what to expect & help us ensure we're not overlooking anything.

Refrain from treating a roadmap as an infallible guide but as a helpful reminder to stay on the right track.

there are many

To start, you can check the resources below.

It's part of a project I maintain to make Web3 accessible to everyone for free.https://t.co/MN0bdhtcV1

Blockchain Fundamentals

Basic concepts about the blockchain.

· Web1, Web2, Web3
· What is a Blockchain
· Distributed Ledger
· Crypto basics
· Smart Contracts
· Wallets
· Block Explorers
· Blockchain Oracles
· NFT Intro
· DAO Intro
· Dapp Intro

Fundamentals are fundamental

Choose a Blockchain:

Each blockchain has its own ecosystem with pros and cons. Choosing one can help you learn and apply concepts.

I went with Ethereum because there's more online material. pic.twitter.com/Al6qzdAXJC

Ethereum Concepts (basics)

Learn the basics of the Blockchain.

For Ethereum:
· Accounts
· Transactions
· Blocks
· EVM
· Gas
· Nodes & Clients
· Networks, Node Providers
· Consensus algorithms
· Beacon Chain
· Side Chains
· The Merge

Ethereum Concepts (Advanced):

If you want to dive a bit deeper, here are some articles and concepts you can explore:

- Ethereum Whitepaper
- Ethereum Trilemma
- "EndGame" (an article by Vitalik)
- Ethereum Yellow Paper

Note that these resources are optional.

Choose a language:

Solidity (recommended for JavaScript/C++/Python developers)

Vyper (recommended for Python developers)

Rust (choose this if you selected Solana as your blockchain)

I chose Solidity because it is the most popular option.

Solidity (Blazing Fast Intro):

It's an oo, high-level language used for implementing smart contracts.

It is statically typed.

It is a curly-bracket language designed to target the EVM.

Solidity supports inheritance, libraries, and complex user-defined types.

Solidity Videos:

Here are some good YouTube channels to learn more about Solidity:

Solidity Support:

- Remix IDE (great for getting started without setting up a local environment)

- Solidity Docs

- Solidity Cheatsheet

- CryptoZombies (a fun online tutorial for beginners) pic.twitter.com/7CO7WMOz5D

— Francesco (@FrancescoCiull4) April 7, 2023

Use a Framework:

Once you have mastered the basics, you can delve deeper by using these tools and working in a local environment:

- MetaMask
- VS Code Solidity Extension
- Truffle
- Hardhat
- Brownie
- Embark

Connect Dapp to Frontend:

Are you a front-end developer? Great news! You don't need to learn a new framework - use a library to interact with the blockchain.

You can use any frontend framework (React, Vue, Angular, Svelte, etc.)

Try using:
- Web3.js
- Ethers.js pic.twitter.com/BElOyPjjIw

Decentralized Storage:

Here are some examples of storage you can use to store your data on the blockchain (similar to databases):

- IPFS
- Arweave
- Filecoin

They are peer-to-peer networks of user-operators who hold a portion of the overall data. pic.twitter.com/O4NdVpLZv8

Mid-Level Tools:

Most of these tools are simple and simplify the process. However, it's better to discover them after understanding the basics.

- Testing Tools: Waffle, Ganache
- OpenZeppelin
- WalletConnect
- Chainlink
- TheGraph pic.twitter.com/u4q6HSNQ5I

— Francesco (@FrancescoCiull4) April 7, 2023

SDKs:

Once you grasp what a dapp is and have made some examples, you may want some support and not write everything alone.

Here are three good ones you can check out:
- Alchemy
- thirdWeb
- Moralis pic.twitter.com/jo7X7MzPVL

Build projects

Build projects! I leave some suggestions where you can get inspiration for building projects, but there are way more on YouTube.

· Solidity by example

· Moralis

· Alchemy

Build in Public!

This is not specific to Web3, but building in public has several benefits:

- You gain a better understanding of the concepts.

- You build an audience.

- You connect with people who share similar interests.https://t.co/tj0HjpHxrO
