How Do Sidechains Differ from Layer 2 Rollups in Their Security Model?
Sidechains are independent blockchains with their own consensus mechanisms, running parallel to the main chain. Their security is derived from their own set of validators or miners.
Layer 2 Rollups, however, inherit their security directly from the Layer 1 main chain. If the L1 is secure, the L2 is secure.
A sidechain's security is generally weaker than the L1 and is not directly tied to the L1's economic security.
