# Bridge - Arbidex ## **What is Arbitrum?** Arbitrum is a layer-2 blockchain that facilitates a better user experience on Ethereum. It ensures a cheaper and faster throughput while leveraging Ethereum’s security. Offchain Labs – a team of reputable engineers with diverse backgrounds behind the protocol. Ed Felten, Harry Kalodner, and Steven Goldfeder founded Offchain Labs in 2018. The New York-based company researches various technological possibilities to enhance Ethereum performance and throughput. There are mainly two reasons why so many developers choose the Arbitrum network: faster transaction processing and lower transaction fees. * **Faster Transaction Processing.** Today, Ethereum network operate under 15 to 20 TPS, a relatively low figure. The Arbitrum network presents a viable tech stack to skyrocket the performance of Ethereum. Analysis shows that it can conveniently process around 40,000 TPS. * **Lower Transaction Fees.** A significant percentage of validators need to confirm the genuineness of a transaction before it can go through on Ethereum. This results in massive backlog in the mempool, with only a small slot being processed per instance. Hence, some traders often add additional fees to their usual gas fees, driving the cost of Ethereum transactions.
