Ethereum Transaction

An Ethereum transaction is an action initiated by an externally-owned account (a user-controlled address) on the Ethereum network that changes blockchain state. Transactions can transfer ETH between addresses, deploy smart contracts, or invoke functions within existing contracts. Each transaction includes essential data: the sender's address, recipient address, value amount, gas price, gas limit, transaction data (bytecode or function calls), and a cryptographic signature proving the sender authorized the transaction. Transactions are propagated through the peer-to-peer network, validated by nodes, and included in blocks by miners or validators who collect transaction fees in return for processing. Example: A user sending 2 ETH to another address is a basic Ethereum transaction, while a more complex transaction might call a Uniswap smart contract to swap tokens, modifying multiple accounts' balances across the blockchain. Why it matters for blockchain technology: Ethereum transactions represent the fundamental unit of state change and user interaction with the blockchain, making them essential to understanding how decentralized applications function and how blockchain state evolves.
