Cross-Consensus Reliable Broadcast and its Applications

We propose a new primitive called cross-consensus reliable broadcast (XRBC). The XRBC primitive models the security properties of communication between two groups, where at least one group executes a consensus protocol. Our experimental results show that all of our protocols achieve low latency and decent throughput.

This artifact demonstrates how to reproduce the results presented in Section 7 of our paper. The experiments do not require any specialized hardware. Our test environment is a computer equipped with a 4-core CPU, 16 GB of RAM, 100 GB of storage, a 100 Mbps network connection, and the Linux operating system.

Note that all results reported in our paper require access to the Amazon EC2. In this artifact appendix, we present the workflow to reproduce scaled-down experiments using one machine.
