Definition ∞ Rollup Fragmentation describes a scenario where the rollup ecosystem becomes overly segmented with numerous, incompatible Layer 2 solutions. This occurs when many different rollups launch, each with its own technical specifications, liquidity pools, and user bases. Fragmentation can hinder interoperability, divide network effects, and complicate user experience across the broader blockchain landscape. It presents challenges for unified development and asset flow.
Context ∞ Rollup fragmentation is a growing concern as the number of Layer 2 scaling solutions continues to increase, particularly within the Ethereum ecosystem. Discussions often focus on the need for better interoperability standards and shared liquidity solutions to counter this trend. The industry is actively exploring bridges and cross-rollup communication protocols to create a more cohesive and efficient scaling environment.
