Layer Two Protocol

Definition ∞ A Layer Two Protocol operates atop an existing blockchain, known as Layer One, to enhance its performance. These protocols process transactions off the main chain, then periodically settle them on the base layer. Their primary purpose is to improve scalability, reduce transaction costs, and increase transaction throughput. This architecture allows the main blockchain to maintain its security and decentralization properties while supporting a higher volume of operations.
Context ∞ Layer Two protocols are a central discussion point in crypto news concerning blockchain scalability challenges, particularly for networks like Ethereum. Reports frequently cover new Layer Two solutions, their adoption rates, and their effectiveness in mitigating high gas fees and slow transaction times. The ongoing development and deployment of these protocols are considered critical for the wider acceptance and practical utility of decentralized applications. Their success directly impacts the user experience and economic viability of various digital asset platforms.
