Let’s talk about Layer 2 networks.
Arbitrum and Optimism are both Optimistic Rollups, while ZKsync and Starknet are ZK Rollups.
One point that’s easy to overlook: Layer 2 security relies mainly on Ethereum mainnet. Data and results ultimately settle on mainnet—this is the main difference between Layer 2s and sidechains.
Before transferring assets from Layer 2 back to mainnet, check whether you’re using the official bridge or a third-party cross-chain bridge. Transfer times and risks vary.
$ARB and $OP are the governance tokens for Arbitrum and Optimism, respectively.
