Layer Two Scalability
Layer two scalability refers to techniques that move transaction processing off the main blockchain to increase speed and reduce costs while maintaining security. By handling the heavy lifting of computation on a separate layer, the main chain can focus on settlement and data availability.
This is essential for high-frequency trading and derivative markets that require rapid execution. Techniques include rollups, state channels, and sidechains.
Each has different trade-offs regarding security and decentralization. The goal is to provide a user experience comparable to centralized exchanges without sacrificing the trustless nature of the underlying blockchain.
This evolution is necessary for the mass adoption of decentralized finance. It allows for complex financial instruments to operate at scale.
