Kernel Components

Kernel Diagram

The kernel components are responsible for managing the unified state and executing essential logic.
  1. Message Box A single contract that defines interface for all Skate Apps to register user intent and corresponding execution tasks. It serves as the entry point for creating intents, and all executors will source this contract for pending actions.
  2. Skate App The base contract that all kernel implementations must inherit from. Skate App does
    • Transforming user intents to imperative tasks for executions.
    • Pushing relevant data into Message Box.
    • Link the kernel app to all periphery apps on destination chains.
An overview of the interaction with Kernel is shown in the diagram below:

In addition, an Executor Registry will live on Skate to register actors with the capability to process user intents. For in-depth details, refer to execution network
