Ethereum is a proof-of-stake smart contract blockchain; ETH is its native asset used for gas, staking, and settlement.
- Also known as
- Ethereum (ETH), Ether
Ethereum is a decentralized blockchain designed to run smart contracts and decentralized applications. It uses an account-based state model and the Ethereum Virtual Machine (EVM) to execute contract code deterministically across the network.
ETH, or ether, is Ethereum's native asset. It is used to pay gas fees, stake validators, settle value, and interact with DeFi, NFT, and DAO applications.
Ethereum launched with proof of work and moved to proof of stake during The Merge in 2022. Validators now propose and attest to blocks by staking ETH, and malicious behavior can be penalized through slashing.
Ethereum's base layer has bounded gas and data capacity, so high demand can raise transaction fees. Its scaling roadmap uses rollups and data-availability improvements to execute more activity on layer-2 systems while publishing data, commitments, or proofs to Ethereum according to each rollup's design.
