Arbitrum
Arbitrum is a Layer 2 scaling solution for Ethereum, designed to enhance the network's speed and reduce transaction costs by processing transactions off-chain and recording them on the Ethereum blockchain. Its native token, ARB, is used for governance and other key aspects of the network's development.

Technology & Use Case
Arbitrum runs on Optimistic Rollups, which bundle multiple Ethereum transactions off-chain and only post compressed data on-chain. This reduces fees and speeds up processing while relying on Ethereum’s security. If anyone disputes a batch, a fraud proof mechanism ensures only valid data is accepted.
Origins & Team
Arbitrum was created by Offchain Labs, founded in 2018 by Princeton researchers Ed Felten, Steven Goldfeder, and Harry Kalodner. Its flagship chain, Arbitrum One, launched in 2021 and quickly became a leading Layer-2 scaling solution for Ethereum, attracting key DeFi protocols.
Ecosystem & Partnerships
Already a major hub for DeFi, gaming, and NFTs, Arbitrum hosts apps like Uniswap, Aave, and Curve. Its governance token, ARB, distributed in 2023, enables decentralized decision-making through the DAO (a community-run system where token holders vote on upgrades). Recent innovations include privacy tools like Trusted Execution Environments (TEE, secure areas inside a computer chip that keep data private) introduced by iExec, expanding Arbitrum’s use for safe and user-friendly dApps.
