What is 30 minutes orb?
Excuse me, could you please clarify what you mean by "30 minutes orb"? As far as I'm aware, the term "orb" is not commonly used in the context of cryptocurrency or finance, and it doesn't have a direct correlation to a duration of 30 minutes. Could you be referring to some specific aspect of a blockchain transaction, or perhaps a new term that I'm not familiar with? It would be helpful if you could provide more context or elaborate on what you're asking about.
