L1 Extension

Definition ∞ An L1 Extension refers to a solution or protocol built to augment the capabilities of a Layer 1 blockchain, such as Ethereum or Bitcoin, without altering its fundamental architecture. These extensions aim to improve aspects like scalability, transaction speed, or data availability for the base layer. They function by providing additional processing capacity or specialized functionalities off-chain or through sidechains. The goal is to enhance overall network performance and utility.
Context ∞ L1 Extensions are a regular subject in blockchain development news, as developers seek ways to overcome the inherent limitations of foundational networks. Reports frequently discuss new layer-2 scaling solutions, rollups, and sidechains designed to handle increased transaction loads. The success of these extensions is crucial for the broader adoption of decentralized applications and the long-term viability of major blockchains.
