Layer Two

Definition ∞ Layer Two refers to a secondary framework or protocol built on top of an existing blockchain network, such as Ethereum. These solutions are designed to enhance transaction speed and reduce costs by processing transactions off the main chain. They process transactions in batches before submitting a summary back to the primary blockchain. Layer Two solutions are critical for improving the scalability of blockchain networks.
Context ∞ Layer Two scaling solutions are currently a focal point of discussion within the blockchain community due to their potential to alleviate congestion on primary networks like Ethereum. Debates often center on the security models, user experience, and specific use cases of different Layer Two technologies, such as rollups and state channels. A critical future development to watch for is the widespread adoption and integration of these solutions, leading to significantly lower transaction fees and faster confirmation times for decentralized applications. Their continued evolution is vital for making blockchain technology more accessible and practical for everyday use.
