kona

Portable implementation of the OP Stack’s fault proof verification logic (kona-host).

This package provides the kona-host binary, which serves as the host program for the fault proof VM (e.g., in cannon-kona trace types).

Installation

sudo apt install kona

Usage

The binary is installed at /usr/bin/kona-host.

It is typically not run manually but invoked by op-challenger when configured for cannon-kona traces.

Integration with Op-Challenger

To use Kona with Op-Challenger:

  1. Ensure kona is installed.

  2. Edit /etc/ethereum/op-challenger.conf.

  3. Set TRACE_TYPE="cannon-kona".

  4. Ensure CANNON_KONA_SERVER="/usr/bin/kona-host" is set (default in new configs).
