Arbitrum (ARB): what you need to knowArbitrum (ARB): what you need to know

Arbitrum is a Layer-2 scaling solution for Ethereum, designed to improve the speed, scalability, and cost-efficiency of the Ethereum network. It uses optimistic rollups to process transactions off-chain and then submits them in batches to the Ethereum blockchain, reducing the load on the main network and lowering transaction fees.

Whitepaper: https://www.lcx.com/arb-mica-white-paper/

Arbitrum processes transactions off-chain using optimistic rollups. This means that transactions are executed outside of the main Ethereum chain and later submitted as a single batch. The system assumes these transactions are valid (hence "optimistic") unless a dispute arises, in which case a fraud-proof mechanism is triggered to verify their validity.

Arbitrum uses optimistic rollups to process transactions off-chain and then batch-submit them to the Ethereum blockchain. This reduces the load on the Ethereum network and lowers transaction costs. The system relies on a fraud-proof mechanism to ensure the integrity of transactions, allowing validators to challenge discrepancies and verify validity when needed.

The Arbitrum ecosystem includes a growing number of decentralized applications (dApps) and DeFi projects that benefit from the platform's scalability and lower fees. Developers can easily migrate existing Ethereum dApps to Arbitrum without significant changes, which supports smooth transition and wider adoption.

Arbitrum was developed by Offchain Labs, a blockchain research and development company founded by Ed Felten, Steven Goldfeder, and Harry Kalodner. The team consists of leading researchers and engineers with expertise in cryptography and distributed systems.
