While chatting with friends, I realized that quite a few people aren’t clear on this.
Arbitrum and Optimism are both Optimistic Rollups, while ZKsync and Starknet are ZK Rollups.
Layer 2s save money by bundling lots of transactions together and writing them back to the mainnet, so the mainnet fees are shared among many users.
$ARB and $OP are the governance tokens for Arbitrum and Optimism, respectively.
If anything isn’t clear, ask in the comments.
