What are the 3 types of voltages?

Excuse me, but could you elaborate on the three types of voltages that are commonly discussed in the realm of cryptocurrency and finance? As a professional in this field, I understand that electrical engineering concepts may not be directly related, but I'm curious to know if there's a metaphorical or analogous application of these terms in our industry. Are you perhaps referring to different levels of risk exposure, security protocols, or perhaps power dynamics within decentralized networks? Clarifying your question would greatly assist me in providing a precise and relevant answer.
