Ethereum (blockchain technology)

Ethereum is a decentralized platform that enables secure and transparent digital transactions and applications without the need for a central authority. It uses blockchain technology—a digital ledger that records all transactions across a network of computers—making data tamper-proof. Ethereum’s key innovation is “smart contracts,” self-executing agreements that run automatically when predefined conditions are met. This allows developers to build decentralized applications (dApps) for various uses, such as finance, gaming, and more. Overall, Ethereum expands blockchain beyond simple currency transactions, enabling complex, trustless, and programmable digital interactions globally.
