What is Arbitrum?
Career: Arbitrum
Arbitrum is a layer 2 scaling solution for the Ethereum blockchain that aims to improve transaction speed and reduce costs while maintaining a high level of security. It operates by processing transactions off-chain and then posting summarized data back to the Ethereum mainnet, which helps alleviate network congestion. Arbitrum uses optimistic rollup technology to achieve this, making it popular for decentralized applications (dApps) and DeFi projects seeking better performance. Developers and users benefit from faster transactions and lower fees compared to using Ethereum directly.
