The combination of Eclipse's execution layer and Celestia's data availability (DA) layer aims to enhance blockchain scalability but faces potential performance bottlenecks. Eclipse leverages the Solana Virtual Machine (SVM) for high-speed transaction execution, while Celestia provides scalable DA through data availability sampling (DAS) and Namespaced Merkle Trees (NMTs). However, challenges include integration complexity, as seamless coordination between layers is critical. Celestia's DAS relies on light node participation, and insufficient nodes could limit throughput. Network latency and data compression efficiency may also impact performance, especially under high transaction loads. Additionally, Eclipse's zero-knowledge proof generation via RISC Zero could introduce computational overhead. Ensuring robust interoperability and optimizing light node bandwidth are key to mitigating these bottlenecks for scalable, efficient performance.
