Is ISO 20022 a big deal?

Excuse me, but could you please elaborate on why ISO 20022 is considered a significant matter in the realm of cryptocurrency and finance? I'm curious to understand the implications it holds for the industry, specifically in terms of enhancing transaction efficiency, security, and interoperability. How does it compare to other standards currently in use, and what are the key advantages it offers that make it stand out? I'm eager to grasp the significance of ISO 20022 and its potential impact on the future of our field.
