$ETH Ethereum (ETH) is an open-source blockchain platform that allows developers to build and deploy smart contracts and decentralized applications (DApps). Launched by Vitalik Buterin in 2015, Ethereum is not only a digital currency (ETH) but also a platform that supports blockchain technology. Its unique features include support for programmable contracts, enabling transactions to be automatically executed when specific conditions are met. Ethereum is transitioning to Ethereum 2.0 to enhance the network's scalability and security, adopting a Proof of Stake (PoS) mechanism aimed at reducing energy consumption and increasing transaction speed.
