Ethereum (ETH) is the second largest cryptocurrency by market capitalization after Bitcoin, but it is more than just a digital currency. Ethereum is a decentralized global software platform based on blockchain technology, and it is known for its ability to run smart contracts and decentralized applications (dApps) without the need for an intermediary. Its native currency, Ether (ETH), is used to pay for transaction fees and computational resources on the network. Ethereum aims to build a new decentralized internet where users can fully control their data and applications, opening up vast opportunities for innovation in areas such as decentralized finance (DeFi), gaming, and non-fungible tokens (NFTs). Thanks to its active community of developers and continuous updates such as the transition to a Proof-of-Stake mechanism, Ethereum continues to evolve as a foundational infrastructure for Web 3.0.
