Nodes can contain the entirety or a segment of Ethereum transaction history, the most recent information about the state of smart contracts, the balances of accounts, and more. At the foundation of Ethereum is the Ethereum Virtual Machine EVM , which is the executable and trustless environment for smart contracts: computer protocols that facilitate, verify, and enforce the negotiation and performance of some sort of digital agreement.
The EVM executes a contract with whatever rules the developer initially programmed, such as sending money from Alice to Bob. The EVM executes these programs through a bytecode language. Ethereum developers are able to use Ethereum programming languages such as Solidity and others to write smart contracts and build decentralized applications.
