What is Arbitrum One?

Arbitrum One, launched by Offchain Labs, is a pioneering Ethereum Layer-2 scaling solution to enhance the scalability and efficiency of decentralized applications (dApps). Employing a groundbreaking technology known as Optimistic Rollup, Arbitrum One can perform transactions at a lower cost and higher speed compared to the Ethereum mainnet. It accomplishes this by moving the majority of computation off-chain, while still securing transactions via the mainnet, ensuring the same level of security as Ethereum itself. 

It offers developers an Ethereum-compatible environment, allowing existing smart contracts to be ported without any modifications. By accelerating transaction speed and lowering costs, Arbitrum One seeks to open up new possibilities for dApp development and usage, making blockchain technology more accessible and user-friendly.
