What does the Oasis Network do?

Could you elaborate on the functions and operations of the Oasis Network? I'm curious to understand how it specifically addresses challenges in the realm of cryptocurrency and finance. Does it provide a platform for secure transactions? Does it have a unique approach to scaling and privacy? I'd also like to know if it's aimed at specific user groups or industries, and how it differs from other blockchain networks. Clarifying these points would help me gain a deeper understanding of the Oasis Network's role and significance in the crypto ecosystem.
