VERIFICATION: PASSED
01_DEFINITION

Strict Definition

"A secondary framework or protocol built on top of an existing blockchain (Layer 1) to improve scalability and reduce transaction costs."

Liability Check // Risk Analysis

The 'Sequencer' risk. Many L2s rely on a central 'Sequencer' to batch transactions. If the sequencer goes down, the network may freeze temporarily, creating uptime risk.
