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."
