Scalable Rollups

Definition ∞ Scalable rollups are layer two blockchain solutions designed to increase transaction throughput and reduce fees by processing transactions off the main chain. These solutions bundle multiple transactions into a single batch, generate a proof of their validity, and then submit this compressed data to the main layer one blockchain. This approach significantly enhances the scalability of blockchain networks without compromising their underlying security. Various types of rollups exist, including optimistic and zero-knowledge rollups, each with distinct verification mechanisms.
Context ∞ The current development landscape for scalable rollups is characterized by intense competition and rapid innovation across multiple blockchain ecosystems. Discussions frequently revolve around the comparative performance, security models, and developer tooling of different rollup implementations. A critical area of focus is the interoperability between various rollup solutions and the main layer one chains, as well as the ongoing efforts to enhance user experience and reduce transaction costs further.
