This is a prototype/PoC implementation of the Byzantine Reliable Broadcast (BRB) as described in the paper Asynchronous Byzantine Agreement Protocols by Gabriel Bracha. This was done for the Summer School DARE2023. Some code was provided from organisers of the Summer School.
The implementation is written in Elixir and can be compiled by running the following command in the root folder of the project: mix compile.
One it is compiled, start the application by running: iex -S mix. This will start an interactive shell with the application loaded.
To start a fixed number of nodes, run the following command in the interactive shell: ChatServerBRB.start_all.
To send a broadcast message, you have to specify the sending node and the message. Run the following command in the interactive shell: ChatServerBRB.brb_broadcast(:elisa, :hi)
