It is at its initial stage of development at the moment.

Purpose

• Have a trade engine that can be used by anyone wanting to understand what a trade engine looks like, or simply use it in an exchange system.

Objective

• Be able to handle large amount of transactions per hour using cheap/affordable off-the-shelf resources.
