Ethereum Execution

Ethereum combines smart contracts, validators, and gas constraints to process on-chain applications.

Smart Contract

A smart contract is code deployed on a blockchain that runs according to predefined rules.

A gas limit caps how much computation a transaction or block can consume.

A validator participates in proof-of-stake consensus by proposing or attesting to blocks.

Staking locks crypto assets to help secure a proof-of-stake network and earn rewards.
