Ethereum is an open-source, permissionless blockchain-based distributed ledger with decentralized governance that provides infrastructure for distributed computing and economic activities. It enables developers to build and deploy decentralized applications, products, and services on the Ethereum network and leverage logic-based transaction automation programs called 'smart contracts'. This smart contract technology enables developers to create unique programs and business logic that execute in a trustless environment, while leveraging the high availability of the global Ethereum network.
