Ethereum Blockchain

Definition ∞ The Ethereum Blockchain is a decentralized, open-source, public blockchain system that features smart contract functionality. It serves as a platform for a wide array of decentralized applications (dApps), including decentralized finance (DeFi) protocols, non-fungible tokens (NFTs), and other distributed ledger technologies. Ether (ETH) is its native cryptocurrency, used to pay for transaction fees and computational services on the network.
Context ∞ Current discussions surrounding the Ethereum Blockchain are dominated by its transition to a proof-of-stake consensus mechanism, known as The Merge, and subsequent upgrades like EIP-4844 aimed at reducing transaction costs. News often focuses on network scalability improvements, the evolution of its developer ecosystem, and its role as a foundational layer for numerous other blockchain projects. Future developments will likely concentrate on further enhancing throughput and decentralization while addressing persistent challenges related to gas fees and network congestion.
