Ethereum (ETH)

The world computer. Build anything, own everything.

What is Ethereum?

Ethereum is a programmable blockchain that goes far beyond simple payments. It introduced smart contracts — self-executing programs that run exactly as written, without middlemen. This single innovation unlocked an entirely new category of applications: decentralized finance, digital ownership, autonomous organizations, and more.

Every decentralized application (dApp) on Ethereum runs on the shared global computer known as the Ethereum Virtual Machine. Developers write code, deploy it to the network, and it becomes available to anyone in the world. No app store approval, no server costs, no single point of failure.

ETH, the native currency, powers everything. It pays for computation (gas fees), secures the network through staking, and serves as the primary unit of value across thousands of protocols built on Ethereum. The Pectra upgrade (May 2025) introduced account abstraction and validator improvements, with the PeerDAS scaling upgrade expected in 2026.

How Ethereum Works

Imagine a giant computer that nobody owns but everyone can use. When a developer writes a program (called a smart contract), they upload it to Ethereum where it lives forever. Anyone can interact with that program — borrow money, trade tokens, create digital art — and the rules are enforced automatically by code, not by a company. ETH is the fuel that keeps this computer running: every action costs a small fee paid in ETH to the people who keep the network secure.

Ethereum Ecosystem

Decentralized finance (DeFi) — lending, borrowing, trading without banks
NFTs and digital ownership — art, music, gaming assets, identity
Staking ETH to earn rewards and secure the network
Layer-2 networks (Arbitrum, Optimism, Base) for faster, cheaper transactions
DAOs — community-governed organizations with transparent treasuries

Team & Development

Ethereum was proposed by Vitalik Buterin in 2013 and launched in 2015. The Ethereum Foundation, a Swiss nonprofit, supports research and development. The broader ecosystem includes thousands of independent developers, companies, and research teams contributing to the protocol and its applications.

Frequently Asked Questions

What can I actually do with ETH?

Hold it as an investment, stake it to earn yield, use it to interact with DeFi protocols (lending, swapping, providing liquidity), buy NFTs, pay for transactions on Ethereum and its layer-2 networks, or participate in DAO governance.

What are gas fees and why do they change?

Gas fees are the cost of using the Ethereum network. They fluctuate based on demand — when many people want to transact at the same time, fees rise. Layer-2 networks like Arbitrum reduce fees by processing transactions off the main chain.

What is Ethereum staking?

Staking means locking up ETH to help validate transactions on the network. In return, you earn rewards (currently around 3-4% annually). You can stake through services like Lido or directly with 32 ETH to run your own validator.

How is Ethereum different from Bitcoin?

Bitcoin is primarily a store of value and payment network. Ethereum is a programmable platform where you can build applications. Both are decentralized, but they serve different purposes. Many investors hold both.
