What is the difference between BSc and DNS?

Could you please elaborate on the distinction between BSc and DNS? Are they both related to cryptocurrency and finance, or do they serve different purposes? I'm curious to understand the fundamental differences in terms of their applications, scope, and relevance in the industry. Additionally, if you could provide some examples or scenarios where one might be more suitable than the other, that would be incredibly helpful. Thank you for your time and expertise in this matter.
