What is Arbitrum

The platform is designed to make it easy for developers to execute unmodified Ethereum Virtual Machine (EVM) contracts and Ethereum transactions at layer-2 while still benefiting from Ethereum’s excellent layer-1 security.

Arbitrum is an L2 optimistic rollup scaling solution for Ethereum, offering a unique combination of benefits:

Trustless security: security rooted in Ethereum, with any validator able to ensure correct Layer 2 results
Compatibility with Ethereum: able to run unmodified EVM contracts and unmodified Ethereum transactions
Scalability: moving contracts’ computation and storage off of the main Ethereum chain, allowing much higher throughput
Minimum cost: designed and engineered to minimize the L1 gas footprint of the system, minimizing per-transaction cost.

Arbitrum itself was created to address some of the shortcomings of current Ethereum-based smart contracts. As for the drawbacks, such as long transactions and high execution costs.
