Inter-Blockchain Communication Message Relay Time Measurement and Analysis in Cosmos

The Cosmos uses an Inter-Blockchain Communication protocol (IBC), which achieves interoperability among heterogeneous blockchains, and horizontal scaling. In Cosmos, inter-chain transactions show lower performance than intra-chain transactions. As the inter-chain transaction rate increases, the entire network's transaction processing speed per second (TPS) decreases. Detail performance evaluations on Cosmos are essential for improving interoperability and designing with the trade-offs between scalability and compatibility. Therefore, this paper proposes a new approach to measure and analyze the inter-chain message relay time in Cosmos. Our results focus on the performance of inter-chain in terms of communication between different chains.
