Ethereum Arbitrum Base

Definition ∞ Ethereum Arbitrum Base refers to the foundational infrastructure that enables Arbitrum, a Layer 2 scaling solution, to operate atop the Ethereum blockchain. Arbitrum is an Optimistic Rollup that processes transactions off-chain, then bundles them and submits a compressed summary to the Ethereum mainnet. This significantly reduces transaction costs and increases throughput compared to direct Ethereum network usage. The base layer provides the security and finality guarantees for these scaled operations.
Context ∞ Ethereum Arbitrum Base is a critical component in the ongoing evolution of Ethereum’s scalability, frequently highlighted in news concerning Layer 2 solutions. Its success is pivotal for expanding the capacity of decentralized applications and reducing user fees. The continued development and adoption of Arbitrum and similar rollups are central to Ethereum’s long-term growth strategy.
