Arbitrum (ARB)

What is Arbitrum One?​

Here are 5 key points about the Arbitrum Blockchain:

  • Arbitrum One is a layer 2 scaling solution for Ethereum, designed to improve the scalability and throughput of the Ethereum network which utilizes Optimistic Rollup Technology as its scaling mechanism.

  • The Optimistic Rollup Technology bundles multiple transactions off-chain and submits a succinct summary (rollup) of these transactions to the Ethereum mainnet for verification.

  • By processing transactions off-chain, Arbitrum offers reduced transaction fees and provides fast transaction finality, with completed transactions settled on the Ethereum mainnet within a relatively short timeframe.

  • Arbitrum ETH is the currency used to pay gas fees and all Arbitrum transactions. You can bridge ETH (and other tokens) from Ethereum to Arbitrum through Arbitrum's bridge.

  • The Arbitrum token (ARB) is an ERC-20 governance token that allows its holders to participate in the Arbitrum DAO's on-chain governance protocol.
