Layer Two Scaling

Definition ∞ Layer Two scaling refers to technologies built on top of an existing blockchain network to improve its transaction processing capacity. These solutions operate independently of the main blockchain, executing transactions off-chain before settling them on the base layer. This approach aims to increase speed and reduce costs without compromising the security of the underlying protocol.
Context ∞ Layer Two scaling solutions are a focal point in discussions about the scalability and usability of blockchain networks, particularly Ethereum. News reports frequently detail the progress and adoption rates of various Layer Two protocols, such as rollups and state channels. The ongoing debate centers on the effectiveness of different scaling approaches, their security implications, and their capacity to support widespread decentralized application usage.
