I learned this the hard way, too.
Layer 2s are scaling networks built on top of Ethereum’s mainnet. They process transactions on Layer 2, then write the data back to the mainnet.
Layer 2 security relies heavily on Ethereum’s mainnet: the data and proofs are ultimately written to the mainnet. That’s the key difference between Layer 2s and independent blockchains.
$ARB and $OP are the governance tokens of Arbitrum and Optimism, respectively.
In what context did you figure this out?
#ARB
