L2 Scaling Solutions
Layer 2 scaling solutions are frameworks built on top of a base blockchain, such as Ethereum, designed to increase transaction throughput and reduce costs while inheriting the security of the main chain. By processing trades and order book updates off the main layer and only submitting a compressed summary or proof to the base chain, these solutions enable high-frequency trading that would otherwise be impossible.
Examples include optimistic rollups and ZK-rollups, which handle the heavy lifting of computation and data storage away from the primary ledger. This dramatically improves the user experience by providing near-instant finality and significantly lower gas fees.
As decentralized exchanges migrate to these scaling layers, the performance gap between centralized and decentralized trading platforms continues to narrow, facilitating wider adoption of on-chain financial services.
