Host Modes

Mode	Description
single	Runs the preimage server + client program for a single-chain (pre-interop.)

Preimage Server Modes

Mode	Description
server	Starts with the preimage server only, expecting the client program to have been invoked by the host process. This mode is intended for use by the FPVM when running the client program.

Usage

kona-host is a CLI application that runs the Kona pre-image server and client program. The host
can run in two modes: server mode and native mode. In server mode, the host runs the pre-image
server and waits for the client program in the parent process to request pre-images. In native
mode, the host runs the client program in a separate thread with the pre-image server in the
primary thread.
