What is ACS pricing?

Excuse me, I'm a bit confused about a concept I've heard about in the cryptocurrency world. Could you possibly elaborate on what ACS pricing stands for and how it functions within the financial ecosystem? I've heard it mentioned in relation to pricing mechanisms for digital assets, but I'm not entirely sure how it differs from traditional pricing models. Would you mind providing a brief yet comprehensive explanation of ACS pricing, its advantages, and how it's being utilized in the current market? Thank you in advance for your clarification.
