An optimistic rollup (ORU) enables refereed delegation of computation from a
blockchain (L1) to an untrusted remote system (L2), by allowing state updates
posted on-chain to be disputed by any party via an interactive fraud proof
(IFP) protocol. Existing systems that utilize this technique have demonstrated
up to a 20x reduction in transaction fees. The most popular ORUs today, in
active development, strive to extend existing Ethereum client software to
support IFP construction, aiming to reuse prior L1 engineering efforts …
