Chapter Three: Advanced FROST Capabilities

Among the more advanced capabilities of FROST are the ability to create shares using Distributed Key Generation (DKG) and the possibility to repair, refresh, and otherwise change shares after the fact.

This chapter overviews these topics, though the latter is not yet available for hands-on experimentation in the CLI.
