$ETH Ethereum is a decentralized blockchain platform that enables the creation and execution of smart contracts and decentralized applications (dApps). Unlike Bitcoin, which focuses primarily on monetary transactions, Ethereum provides a more versatile infrastructure that facilitates the programming of self-executing contracts without third-party intervention.

Ether (ETH) is the platform's native cryptocurrency and is used to pay for transactions and computing services within the network.

Ethereum is significant because it has revolutionized the use of blockchain technology, enabling innovation in various sectors, such as decentralized finance (DeFi), non-fungible tokens (NFTs), and various automated applications, ensuring transparency, security, and efficiency in a wide range of processes.
