What is Blockchain?

Beginner

Understanding the fundamental technology that powers Ethereum and other cryptocurrencies.

Key Concepts:

A blockchain is a digital ledger of transactions
Information is stored in blocks linked together
It's decentralized - no single point of control
Every transaction is verified by network participants
Example:

Think of blockchain like a shared notebook that everyone can read but no one can erase or change past entries.

What is Ethereum?

Beginner

Learn about Ethereum as a platform for programmable money and decentralized applications.

Key Concepts:

Ethereum is a blockchain platform launched in 2015
Unlike Bitcoin, it can run smart contracts (programs)
ETH is the native currency used to pay for operations
It enables decentralized applications (DApps)
Example:

If Bitcoin is like digital gold, Ethereum is like a decentralized computer that anyone can use to build applications.

Digital Wallets

Beginner

How to safely store and manage your Ethereum and other digital assets.

Key Concepts:

Wallets store your private keys, not actual coins
Private keys prove ownership of your assets
Never share your private key or seed phrase
Popular wallets include MetaMask, Coinbase Wallet
Example:

A wallet is like a bank account, but instead of the bank controlling it, you have complete control with your private key.

Transactions & Gas

Beginner

Understanding how transactions work on Ethereum and why there are fees.

Key Concepts:

Every action on Ethereum requires a transaction
Gas is the unit that measures computational work
Gas fees compensate network validators
More complex operations cost more gas
Example:

Gas is like postage for mail - simple letters cost less to send than heavy packages.

Popular DApps

Beginner

Explore the most common types of decentralized applications built on Ethereum.

Key Concepts:

DeFi apps for lending, borrowing, and trading
NFT marketplaces for digital collectibles
Gaming applications with true ownership
Decentralized social networks and messaging
Example:

Uniswap lets you trade tokens without a traditional exchange, while OpenSea is like eBay for digital collectibles.

Ethereum vs Bitcoin

Beginner

Key differences between the two most important cryptocurrencies.

Key Concepts:

Bitcoin focuses on being digital money
Ethereum enables programmable applications
Bitcoin uses Proof of Work, Ethereum uses Proof of Stake
Ethereum has faster transaction times
Example:

Bitcoin is like digital cash, while Ethereum is like a smartphone - it can run many different applications.
