Ethereum is the largest smart-contract platform — a programmable blockchain that powers most of decentralized finance, stablecoins, NFTs and tokenized real-world assets.
What is Ethereum?
Ethereum is a decentralized, open-source blockchain with built-in programmability. Where Bitcoin focuses on being money, Ethereum behaves like a global, shared computer: developers deploy “smart contracts” — self-executing programs — that run exactly as written without intermediaries. ETH, its native asset, is used to pay for computation (“gas”), to secure the network through staking, and increasingly as collateral across on-chain finance.
The origins of Ethereum
Proposed by Vitalik Buterin in 2013 and launched in 2015, Ethereum set out to generalize the blockchain from simple payments to arbitrary applications. It catalyzed entire industries — the 2017 token boom, the 2020 “DeFi summer,” and the NFT wave — and in 2022 completed “the Merge,” a years-in-the-making transition from energy-intensive mining to proof-of-stake.
How Ethereum works
Since the Merge, Ethereum is secured by proof-of-stake: validators lock up ETH to propose and attest to blocks, earning rewards for honest behavior and risking “slashing” for misconduct. Every transaction pays a base fee that is burned under the EIP-1559 mechanism, plus a tip to validators. Most everyday activity now happens on layer-2 “rollups” that batch transactions cheaply and settle back to Ethereum mainnet for security.
ETH supply and tokenomics
Unlike Bitcoin, Ethereum has no fixed maximum supply. Net issuance is the difference between new ETH paid to validators and the ETH burned via transaction fees, so during periods of heavy network use ETH can become net deflationary. This makes ETH both a productive, yield-bearing asset (through staking) and one whose supply responds to real demand for blockspace.
What moves the Ethereum price
ETH is driven by network usage and fees, staking participation, the growth of its layer-2 ecosystem, spot-ETF flows and the broader appetite for on-chain finance. Because ETH is both a “tech” asset and the collateral backbone of DeFi, it is sensitive to both risk sentiment and genuine on-chain activity.
Risks to understand
Smart-contract bugs, validator slashing, layer-2 and bridge risks, competition from other chains and shifting regulation are all real considerations. ETH is volatile and staked ETH can carry lock-up and technical risks. This is educational content, not financial advice.
The Ethereum ecosystem
Ethereum hosts the deepest application ecosystem in crypto. Decentralized finance lets users lend, borrow, trade and earn yield without intermediaries; stablecoins like USDC and USDT settle enormous volumes on it; NFTs and on-chain identity live here; and tokenized real-world assets — from treasuries to funds — are increasingly issued on Ethereum and its layer-2s. This composability, where applications snap together like building blocks, is a core reason developers continue to build on the network despite competition.
Staking and earning on Ethereum
Holders can put ETH to work by staking. Running your own validator requires 32 ETH and technical upkeep; pooled and liquid-staking services lower the barrier so anyone can earn a share of network rewards, with liquid staking issuing a token that represents the staked position and can be used elsewhere in DeFi. Staking yields move with network activity and the total amount staked, and carry technical and smart-contract risks worth understanding before committing funds.
Ethereum’s scaling roadmap
Ethereum’s long-term strategy is “rollup-centric”: most activity happens on layer-2 networks that bundle transactions and post compressed data back to mainnet, which provides security. Upgrades have steadily reduced the cost of that data, making layer-2 transactions dramatically cheaper. The result is a base layer optimized for security and settlement, with scale delivered by a growing constellation of rollups rather than by making the main chain itself process everything.

Ethereum FAQ
What is the difference between Bitcoin and Ethereum?
Bitcoin is primarily a fixed-supply store of value. Ethereum is a programmable platform for applications, with a flexible supply and staking yield. They solve different problems.
Can you stake ETH?
Yes. ETH holders can run a validator or use pooled/liquid staking to earn rewards for helping secure the network. See our staking-yields comparison for current rates.
Is Ethereum deflationary?
It can be. When fee burning exceeds new issuance — typically during busy periods — ETH’s supply shrinks. During quiet periods it can be mildly inflationary.
Is Ethereum better than Bitcoin?
They are not directly comparable — Bitcoin optimizes for sound, fixed-supply money, while Ethereum optimizes for programmability. Many investors hold both for different reasons.
