Arbitrum is a blockchain scaling solution that aims to improve the scalability and efficiency of the Ethereum network. It is built by Offchain Labs, a blockchain technology company.

Arbitrum uses a technique called rollups, which is a Layer 2 scaling solution that allows multiple transactions to be processed off-chain and then bundled together and submitted to the Ethereum mainnet. This helps to reduce congestion and increase the throughput of the network.

One of the key features of Arbitrum is its compatibility with existing Ethereum smart contracts. It uses a virtual machine called the Arbitrum Virtual Machine (AVM) that can execute Ethereum contracts, allowing developers to easily port their applications to Arbitrum with minimal modifications.

Arbitrum also offers enhanced security by utilizing fraud proofs. These proofs enable users to challenge any invalid transactions that occur on the network, ensuring the validity and integrity of the system.

The goal of Arbitrum(#Arb ) is to provide a scalable and cost-effective solution for decentralized applications (dApps) on the Ethereum network. By reducing transaction fees and increasing transaction throughput, it aims to enhance the user experience and allow for the widespread adoption of Ethereum-based applications.
