Modular Layer Two

Definition

A modular Layer Two solution is a scaling technology built on top of a base blockchain, such as Ethereum, designed to process transactions off-chain and then settle them back on the main chain. Its modular nature means different components, like execution, data availability, and settlement, can be independently optimized or replaced. This architecture significantly enhances transaction throughput and reduces fees while inheriting the security properties of the underlying Layer One. It represents a flexible approach to blockchain scalability.
