Arbitrum Insights

What is Arbitrum?

Arbitrum is a suite of Ethereum scaling solutions designed to increase transaction speed and reduce transaction costs. It achieves this through optimistic rollup technology, where transactions are executed off-chain and then batched and posted to the Ethereum mainnet. A challenge period allows validators to dispute potentially fraudulent transactions. This enables faster and cheaper transactions while still inheriting the security of Ethereum.
