What is the onus example?

Could you please clarify what you mean by 'onus example' in the context of cryptocurrency and finance? Are you referring to an example of a situation where a specific responsibility or burden falls on a party, such as a cryptocurrency exchange or investor? Or perhaps you're asking for an illustration of how the concept of onus can be applied in the world of digital assets and financial transactions? It would be helpful if you could provide a bit more context or specify what area of cryptocurrency or finance you're specifically interested in exploring.
