What is the CTX test used for?

I'm curious to understand the purpose and significance of the CTX test in the cryptocurrency and finance world. Could you elaborate on what it stands for, what it measures, and how it's utilized in the industry? Is it a diagnostic tool for assessing the security of a blockchain? Or does it assess the performance of a particular cryptocurrency or trading strategy? Understanding its function and relevance would greatly aid in my comprehension of the broader financial landscape.
