Ethereum ($ETH): The Backbone of Decentralized Innovation
Ethereum is more than just a cryptocurrency—it's the foundation of a decentralized world. Launched in 2015 by Vitalik Buterin and others, Ethereum introduced smart contracts: self-executing agreements coded directly on the blockchain. This innovation sparked the growth of DeFi (Decentralized Finance), NFTs, DAOs, and countless dApps, reshaping how we interact online. Unlike Bitcoin, which primarily serves as digital gold, Ethereum acts as a flexible platform for developers to build decentralized applications.
With the successful transition from proof-of-work to proof-of-stake (Ethereum 2.0), Ethereum has significantly reduced its energy consumption, addressing key environmental concerns. As scalability solutions like layer-2 rollups continue to develop, ETH is poised for mainstream adoption.
At over $150, Ethereum holds strong as the second-largest cryptocurrency by market cap. Whether you're an investor, developer, or enthusiast, ETH remains a cornerstone of Web3 innovation and a gateway into the future of digital finance.
