Dymension Hub (Dymension) is a Layer-1 network that serves as a modular settlement and consensus layer, whereas its application-specific Layer-2s serve as modular execution layers. Dubbed “RollApps,” the Layer-2s are “enshrined,” meaning Dymension is aware of them and is optimized for maintaining the state of each one. This is in contrast to Ethereum Layer-2s, which rely on smart contracts on Ethereum for settlement and data availability.
