$ETH Ethereum is a decentralized, open-source blockchain platform that goes beyond digital currency by enabling developers to create decentralized applications (dApps) using smart contracts—self-executing code that operates without downtime or third-party interference. Launched in 2015, Ethereum quickly became a key player in decentralized finance (DeFi), NFTs, and Web3 innovation. Its native cryptocurrency, ETH, is used to power transactions and run applications on the network. With the transition to proof-of-stake through Ethereum 2.0, the platform significantly improved its scalability and energy efficiency. This upgrade supports a more sustainable blockchain future. Ethereum remains at the forefront of decentralized technology, continuing to shape the way we interact with digital assets and applications across various industries.
