Understand how Optimistic Rollups batch transactions off-chain and rely on fraud proofs to ensure validity, achieving significant throughput improvements while inheriting Ethereum's security.
Background Lore
As Ethereum grew, its mainnet became congested with thousands of transactions competing for block space. Gas fees rose, and adventurers sought new lands beyond Layer 1. Optimistic Rollups emerged as a bridge between worlds -- executing transactions in a faster realm while anchoring trust back to the mainnet through a challenge period.
