What is Arbitrum?
Arbitrum (ARB) is a layer-two scaling network for Ethereum. It launched in 2021, built by a team called Offchain Labs, to ease Ethereum's congestion by handling transactions away from the main chain while still relying on Ethereum for security. The ARB token is used for governance, letting holders vote on how the protocol develops.
Arbitrum uses a method known as optimistic rollups. It bundles many transactions together, processes them off-chain, and posts a compact proof back to Ethereum. The result is much lower transaction costs and far higher throughput than using Ethereum on its own, without giving up Ethereum's underlying security.
Because Arbitrum is compatible with Ethereum, applications and smart contracts already written for Ethereum can run on it with little or no change. That has helped a large ecosystem form on the network, spanning DeFi protocols, NFT marketplaces and on-chain games, with a significant amount of value in use across those apps.
As demand on Ethereum keeps growing, layer-two networks like Arbitrum handle everyday activity at a fraction of mainnet cost. Holding ARB lets you take part in decisions that steer the protocol, and use the many applications that have chosen Arbitrum as their home.
