What is an ontology network?

Could you please explain what an ontology network is? I've heard of blockchain technology and its applications, but the concept of an ontology network is new to me. How does it differ from other blockchain platforms? What are its main features and advantages? How does it work, and what kind of use cases does it have in the cryptocurrency and finance industries? I'm eager to learn more about this emerging technology and its potential impact on the future of digital assets.
