Layer Two Network

Definition ∞ A Layer Two Network is a secondary protocol built atop an existing blockchain, known as Layer One, to enhance its scalability and efficiency. These networks process transactions off the main chain, bundling them before submitting a summarized record to the Layer One blockchain. This approach reduces transaction fees and increases transaction throughput. Examples include rollups and sidechains, which address the limitations of foundational blockchains.
Context ∞ Layer Two networks are a central topic in discussions about blockchain scalability and the future of decentralized applications. Their development is critical for enabling widespread adoption of high-volume activities, such as gaming or micro-payments, on congested Layer One chains. News frequently highlights advancements in Layer Two technology, new protocol launches, and the migration of applications to these more efficient environments.
