What is the Context of Layer Two Scalability?

The discussion surrounding Layer Two scalability frequently addresses the trade-offs between security, decentralization, and efficiency across different solution types. A key challenge involves ensuring the security of funds locked in Layer Two protocols and facilitating seamless asset transfers between layers. Future developments are expected to include further optimization of data availability layers, improved cross-rollup communication, and enhanced user experience for Layer Two applications.

Layer Two Scalability

Definition

Layer Two scalability refers to solutions built on top of a main blockchain, known as Layer One, to increase its transaction throughput and reduce fees. These solutions process transactions off the main chain and then periodically submit a summary or proof of these transactions back to Layer One. This approach alleviates congestion on the base layer, making the network more efficient and cost-effective for users. Examples include rollups, state channels, and sidechains.
