# Order Book

In the system, the fundamental unit of planning is a task. A task is defined as a set of one or more instructions from the Instruction Set Architecture (ISA). The allocation of tasks to actors is managed at the Orchestration Layer through the order book.

Each task that requires execution is transformed into an order. An order encapsulates the task along with its associated metadata, which specifies the requirements for execution. This metadata includes:

* **Deadline:** The maximum allowable time for task completion.
* **Maximum Reward:** The upper limit of compensation for completing the task.
* **Complexity:** A quantitative measure of the computational resources required for execution.
