Layer Two Security

Definition

Layer two security comprises the protective measures and assurances that safeguard transactions and operations conducted on scaling solutions built atop a main blockchain network. This refers to the security mechanisms of protocols like rollups or sidechains, which aim to increase transaction throughput and reduce costs while inheriting security from the underlying layer one. Ensuring the integrity of these off-chain computations and their eventual settlement on the base chain is critical. Proper design prevents exploits that could compromise funds or data.
