Ethereum ($ETH) is a decentralized blockchain platform known for its smart contract functionality. Unlike Bitcoin, which is primarily a digital currency, Ethereum allows developers to build and deploy decentralized applications (dApps). Its native cryptocurrency, Ether (ETH), powers transactions and computational services on the network. Ethereum is transitioning from Proof of Work (PoW) to Proof of Stake (PoS), enhancing scalability, energy efficiency, and security. This upgrade, known as Ethereum 2.0, positions ETH as a key player in the future of decentralized finance (DeFi), NFTs, and Web3. As adoption increases, Ethereum continues to drive innovation in the blockchain space.
