$ETH is a blockchain platform created by Vitalik Buterin in 2015, designed to support smart contracts and decentralized applications (dApps). Unlike Bitcoin, which focuses on being a medium of exchange, Ethereum allows developers to build applications on its network, opening possibilities in sectors such as finance, art, and gaming. With the transition to Ethereum 2.0 and the use of Proof of Stake, it aims to improve its scalability and energy sustainability. ETH, its native cryptocurrency, is essential for operating within the network. Ethereum has driven the Web3 revolution, establishing itself as a pillar in the crypto ecosystem.
