## Layer Two Scaling Solutions

Layer two scaling solutions are protocols built on top of a primary blockchain, such as Ethereum, designed to increase transaction throughput and reduce costs by processing transactions off the main chain. By moving the heavy lifting of computation away from the base layer, these solutions maintain the security of the mainnet while enabling faster and cheaper interactions.

Common types include rollups, which bundle multiple transactions into a single proof submitted to the main chain, and state channels. These solutions are critical for the growth of decentralized finance, as they allow for high-frequency trading and complex derivatives that would be prohibitively expensive on the base layer.

They effectively mitigate the network congestion that often plagues popular blockchains. From a risk perspective, they introduce new attack vectors related to bridge security and sequencer centralization.

Investors and users must evaluate the trade-offs between different scaling architectures, such as optimistic versus zero-knowledge rollups. As these technologies mature, they are becoming the primary venues for institutional and retail financial activity.

They represent the necessary infrastructure for mass adoption.
