Crypto 101 📚 Layer 2 Networks
Optimistic Rollups assume transactions are valid by default and have a challenge period. Withdrawing to mainnet via the official cross-chain bridge generally takes about 7 days.
ZK Rollups use validity proofs to demonstrate to mainnet that state changes are correct, so withdrawals to mainnet don't require such a long challenge period.
I didn't understand this back then, and the tuition I paid could have bought me several hot pot meals.
$ARB and $OP are the governance tokens of Arbitrum and Optimism, respectively.
