Arbitrum One
Arbitrum is a suite of Ethereum Layer 2 scaling solutions designed to improve transaction speed, reduce gas costs, and enhance developer experience on Ethereum.
Overview
Arbitrum is a leading Layer 2 scaling solution built to enhance the Ethereum ecosystem by enabling faster and cheaper transactions while maintaining strong security guarantees. It achieves this through rollup technology, which processes transactions off-chain and submits compressed proofs to Ethereum’s mainnet. The Arbitrum suite includes multiple protocols such as Arbitrum Rollup for secure scaling, Arbitrum AnyTrust for higher throughput with mild trust assumptions, and Arbitrum Stylus, which allows developers to write EVM-compatible smart contracts in Rust and other WebAssembly-compatible languages.
Developers can deploy decentralized applications (dApps) on public Arbitrum chains like Arbitrum One (Rollup) and Arbitrum Nova (AnyTrust), or launch their own custom chains using Arbitrum Orbit. The ecosystem supports over 900 applications, including decentralized exchanges, NFT marketplaces, and wallets. Users interact with Arbitrum primarily through the Arbitrum Bridge, which facilitates seamless token transfers between Ethereum and Arbitrum chains. Node operators can run Arbitrum Nitro nodes to support the network and access chain data directly.
Arbitrum differentiates itself with its modular architecture, high throughput, and developer-friendly tools such as the Arbitrum SDK and comprehensive documentation. Its open governance model via the Arbitrum DAO allows the community to influence protocol upgrades and economic parameters. With over 1.45 million active wallets, $20 billion in total value locked, and 2.24 billion transactions processed, Arbitrum holds a dominant 36.1% market share among Layer 2 solutions. Developers can get started quickly using Solidity or Stylus smart contract tutorials, and node runners have detailed guides to deploy and maintain nodes. Comprehensive resources and active community support facilitate onboarding and ongoing development.
The Problem
Ethereum’s mainnet faces scalability challenges including high gas fees, slow transaction throughput, and limited capacity for complex dApps. These issues hinder user experience and restrict the growth of decentralized applications.
