Arbitrum is a protocol that enhances the speed and affordability of Ethereum transactions. Developers leverage Arbitrum to construct dApps that are user-friendly and can benefit from the scalability perks offered by the Arbitrum Rollup and AnyTrust protocols.
In 2021, Arbitrum launched its primary chain, Arbitrum One, which was soon succeeded by the introduction of Arbitrum Nova, an independent AnyTrust chain designed to provide transactions at a significantly reduced cost. In August 2022, Arbitrum One underwent an upgrade to the Arbitrum Nitro stack, resulting in a 7-10x boost to its scaling abilities.
