What is a Layer 2?
Rollups are currently the most widely used Layer 2 solution, and come in two types: Optimistic Rollups and ZK Rollups.
Layer 2 security relies primarily on Ethereum mainnet: transaction data and proofs ultimately need to be posted to mainnet. This is the main difference between Layer 2s and independent blockchains.
$ARB and $OP are the governance tokens of Arbitrum and Optimism, respectively.
Verify information with multiple sources before making a decision—don't rely on just one source.
