Rollup (Optimistic vs. ZK)
NODE: ROLLUP
VERIFICATION: PASSED
01_DEFINITION
Strict Definition
"A Layer 2 scaling solution that executes transactions off-chain and then 'rolls them up' into a single batch to be settled on Layer 1."
Liability Check // Risk Analysis
The 'Waiting Period vs. Proof Complexity' risk. Optimistic rollups have a 7-day withdrawal delay. ZK-rollups (Zero-Knowledge) are faster but rely on complex math where a single bug can break the entire proof system.

Auditor NotesVS-AN-2026
Strategy Domain
"Use Optimistic rollups (Arbitrum/Optimism) for established ecosystems and ZK-rollups (zkSync/Polygon zkEVM) for high-privacy or instant-exit needs."
Operations Standard
"Utilize 'Bridge Aggregators' to bypass the 7-day optimistic waiting period for small corporate withdrawals."
Legal & Compliance
"Document the 'Finality Time' of each rollup to determine when a transaction is legally considered 'Settled' in your books."
