Arbitrum Network

Definition ∞ The Arbitrum Network is a layer-two scaling solution designed to enhance the transaction throughput and reduce the costs associated with the Ethereum blockchain. It employs optimistic rollups, which bundle multiple transactions off-chain and submit a single proof to the main Ethereum chain. This architecture significantly improves transaction speed and affordability for decentralized applications.
Context ∞ News concerning the Arbitrum Network often centers on its growing ecosystem adoption, protocol upgrades, and the impact of its native token, ARB, on decentralized finance. Developers and users are keenly observing its progress in onboarding new dApps and its role in driving Ethereum’s scalability narrative, particularly as it competes with other layer-two scaling solutions.
