Arbitrum, Ethereum layer-2 scaling solution, will undergo one of its largest upgrades on Wednesday. This upgrade is expected to increase transaction throughput and reduce transaction fees, as well as simplify cross-chain communication between Arbitrum, Ethereum, and Arbitrum.
Arbitrum, also known as the “Nitro”, confirmed the date in a tweet on Aug. 29. It stated that the upgrade would take effect at 10:30 Eastern Time on Aug. 31, while noting that there will be a two- to four hour downtime.
Reminder: Arbitrum One will be upgrading to Nitro on Wednesday, 8/31. The planned network downtime will start at 10:30 AM ET/ GMT-4. There are 2 days left until Nitro!

Abritrum, an Ethereum layer-2 scaling solution, uses Optimistic Rollup technology. It bundles large batches of transactions off-chain using Ethereum smart contracts and decentralized apps before submitting them to Ethereum.
Offchain Labs’ GitHub account states that Nitro will be a fully integrated, complete layer-2 optimistic rollup system. It builds on Arbitrum One and features improved fraud proofs as well as updated sequencers and token bridges.
Offchain Labs, a blockchain-based firm founded in 2018, develops a range of Ethereum scaling solutions. The most prominent network is the Arbitrum One network.
Arbitrum will flip Solana. It is only days away that Aribtrum Nitro will be available. It will bring faster transactions, lower fees, and better experiences for builders. @arbitrum pic.twitter.com/95Edqn881u

Offchain Labs has also updated the ArbOS (Arbitrum Operating System), component. This is now written in Go, a software programming language. This new version will allow for cross-chain communication between Arbitrum (Ethernet) and transaction batching, data compression, and reduce costs on the Ethereum mainnet.
It also stated that Arbitrum One’s state “will be seamlessly migrated” to Nitro. This should eliminate any chance of a chain splitting if done correctly.
Offchain Labs stated in an April. Offchain Labs stated that the Arbitrum Nitro upgrade will be “the most advanced Ethereum scaling platform” and that “Nitro would massively increase network bandwidth and reduce transaction costs.”
“Today we limit Arbitrum’s ability, but with Nitro, we can release those controls, and significantly increase our throughput. Even though Arbitrum is currently 90-95% cheaper than Ethereum, Nitro reduces our costs even more.
Arbitrum, according to DeFi Llama (aggregator of decentralized finance), has $936 million in total value (TVL). The network is spread across 111 protocols with GMX and Stargate being the most popular.
