kona-host

kona-host is a CLI application that runs the pre-image server and client program.

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.
native Starts both the preimage oracle and client program in a native process. This mode is useful for witness generation as well as testing.

Usage

Usage: kona-host [OPTIONS] --l1-head <L1_HEAD> --l2-head <L2_HEAD> --l2-output-root <L2_OUTPUT_ROOT> --l2-claim <L2_CLAIM> --l2-block-number <L2_BLOCK_NUMBER>

Options:
  -v, --v...
          Verbosity level (0-2)
      --l1-head <L1_HEAD>
          Hash of the L1 head block. Derivation stops after this block is processed
      --l2-head <L2_HEAD>
          Hash of the L2 block committed to by `--l2-output-root`
      --l2-output-root <L2_OUTPUT_ROOT>
          Agreed L2 Output Root to start derivation from
      --l2-claim <L2_CLAIM>
          Claimed L2 output root at block # `--l2-block-number` to validate
      --l2-block-number <L2_BLOCK_NUMBER>
          Number of the L2 block that the claim commits to
      --l2-node-address <L2_NODE_ADDRESS>
          Address of L2 JSON-RPC endpoint to use (eth and debug namespace required) [aliases: l2]
      --l1-node-address <L1_NODE_ADDRESS>
          Address of L1 JSON-RPC endpoint to use (eth and debug namespace required) [aliases: l1]
      --l1-beacon-address <L1_BEACON_ADDRESS>
          Address of the L1 Beacon API endpoint to use [aliases: beacon]

      --l2-chain-id <L2_CHAIN_ID>
          The L2 chain ID of a supported chain. If provided, the host will look for the corresponding rollup config in the superchain registry
      --rollup-config-path <ROLLUP_CONFIG_PATH>
          Path to rollup config. If provided, the host will use this config instead of attempting to look up the config in the superchain registry
