Throughput Capability refers to the system's capacity to handle a significant number of cross-chain messages within a defined timeframe. This feature is crucial for ensuring that transactions and communications between different blockchain networks occur seamlessly and without delays. High throughput is essential for maintaining user satisfaction and operational efficiency, especially in environments where real-time data exchange is critical. By optimizing throughput, the system can support a larger user base and facilitate more complex decentralized applications that rely on cross-chain interactions.
