User Interface

ByzzBench includes a user interface that allows to visualize and control the execution of the protocol.

How serialization works

Serialization of Java classes is handled by the Spring Boot framework, using the Jackson library.

It will also include the values returned by Getters (methods that start with get or is), unless they are also annotated with @JsonIgnore.
