What is Ethereum?
Cryptocurrencies like Bitcoin enable global money transfers for anyone. Ethereum does this too—but it also executes code, allowing people to build applications and organizations. It combines flexibility and adaptability: any computer program can run on Ethereum. Below, we explore its core components and how to get started:
What is Ether (ETH)?
Ether (ETH) is the currency powering the Ethereum network and its applications.

Key Ethereum Basics
- Smart contracts: Self-executing agreements coded on Ethereum.
- Decentralization: No single entity controls the network.
How Can I Use Ethereum?
Ethereum offers diverse use cases: logging into apps, verifying online identity, or transferring ETH. To start, you’ll need an account, best managed via a wallet.
What is a Wallet?
Digital wallets store tools to authenticate identity and access decentralized services.

Ethereum Networks
Save costs using Layer 2 solutions—scalable networks built atop Ethereum.
- Popular options: Optimism, Arbitrum, Polygon.
Considerations When Using Ethereum
- Gas fees: ETH is required for all transactions (even for moving stablecoins like USDC).
- High traffic: Fees spike during peak usage—Layer 2 networks mitigate this.
What Can Ethereum Do?
Ethereum enables innovations across industries:
- DeFi: Decentralized lending, trading, and more.
- NFTs: Unique digital assets.
- DAOs: Community-governed organizations.
Strengthening the Ethereum Network
Stake ETH
Secure Ethereum while earning rewards by staking ETH. Options include:
- Solo staking (technical expertise required).
- Pooled staking (simpler for beginners).
Run a Node
Contribute to decentralization by operating a node.
