NFT stands for Non-Fungible Token. It’s a digital item that lives on the blockchain and proves ownership of something unique—usually art, music, videos, collectibles, or access passes.

• “Non-fungible” means it’s one-of-a-kind. Unlike dollars or Bitcoin (which are interchangeable), each NFT has its own unique identity and value.
  
• NFTs can represent digital or real-world items, and owning one is like holding a signed certificate of authenticity, stored digitally.
  
• People use NFTs to collect, support artists, unlock perks, or even trade them like rare cards.
  

Think of it like owning an original piece of art—but instead of hanging it on your wall, it lives in your digital wallet.

The blockchain is like a digital ledger (or notebook) that records every transaction securely and publicly. It’s what powers NFTs, cryptocurrencies like Bitcoin and Ethereum, and more.

Here’s a simple breakdown:

• It's decentralized, meaning no single company or person controls it. Instead, it's shared across thousands of computers around the world.
  
• Every time something is bought, sold, or transferred on the blockchain, it's added to a block of data.
  
• These blocks link together—forming a chain—and once something’s recorded, it can’t be changed or deleted.
  

This is what makes blockchain so powerful: it’s transparent, tamper-proof, and always available for anyone to verify.

A crypto wallet is your digital keychain for Web3. It’s how you store, send, and receive cryptocurrencies, NFTs, and other digital goodies.

But here’s the cool part:
Your wallet doesn’t actually hold your assets—it holds the keys (kind of like a password) that prove you own them on the blockchain.

There are two main types:

• Hot Wallets: Apps or browser extensions (like MetaMask or Phantom). Easy to use, always online.
• Cold Wallets: Physical devices (like Ledger or Trezor). Super secure, great for long-term storage.

With your wallet, you can:

• Collect and trade NFTs
  
• Log into Web3 sites without a password
  
• Join token-based communities or events
  
• Control your digital identity
  

Important: Your wallet is only as safe as you are. Never share your seed phrase, and be careful what you click

Web3 is the next version of the internet—one where you actually own part of it.

In today’s internet (we call it Web2), big platforms like social media or marketplaces control your content, your data, and sometimes even your money. Web3 flips that on its head by using the blockchain to give power back to users.

Here’s what makes Web3 different:

• You own your stuff. NFTs, tokens, and even usernames can live in your digital wallet—not locked in someone else’s app.
  
• No middlemen. Want to sell your art, run a game, or launch a community? You can do it directly with your fans or friends, without going through a company.
  
• It’s open and decentralized. Anyone can build or participate. The rules are baked into the code, not made up on the fly.
  

So in short: Web3 = the internet, but with superpowers.

• Web1: Read — Like a library. You could read websites, but couldn’t interact much. (Think: early 2000s.)
• Web2: Read + Write — Like social media. You can post, comment, create—but companies own the platform (and your data).
• Web3: Read + Write + Own — Like owning your own part of the internet. You control your assets, data, and identity through the blockchain.
