Ethereum Virtual Machine (EVM)

What Is the EVM?

The EVM (Ethereum Virtual Machine) is a decentralized computing environment that executes smart contracts on the Ethereum blockchain, serving as the runtime environment where all Ethereum transactions and smart contract operations are processed.

Acting as a world computer, the EVM provides a standardized, isolated execution environment that ensures smart contracts run identically across all nodes in the network, enabling deterministic and verifiable computation without relying on centralized servers.

How It Works

The EVM is the engine that runs smart contracts on Ethereum. It takes the code written by developers, converts it into low-level instructions, and executes them step by step. Each action, like doing a calculation, saving data, or calling another contract, costs a small amount of gas. Gas limits how much work a contract can do, which prevents abuse and keeps the network secure. The EVM also runs in a closed environment, so smart contracts cannot access external systems or interfere with the computer running the network.

What does EVM-compatible mean?

Being EVM-compatible means a blockchain can execute smart contracts and dApps written for Ethereum without significant code changes. These networks use the same tools (MetaMask, Solidity) and address formats, which enables developers to easily migrate apps and users to transition seamlessly between chains that are faster and cheaper.

Key EVM Features

• EVM compatibility allows the same smart contracts to run on multiple blockchains like Polygon and Avalanche
• Gas mechanism prevents network spam by requiring payment for computational resources
• Deterministic execution ensures identical results across all network nodes for consensus

The EVM’s design has become the de facto standard for smart contract platforms, with dozens of EVM-compatible blockchains enabling developers to port Ethereum applications with minimal modifications while benefiting from faster transactions and lower fees.
