What are the three types of mantle?

Could you please elaborate on the three types of mantle you mentioned earlier? I'm quite interested in understanding the distinctions between them. Are they related to the technical aspects of cryptocurrencies, perhaps in terms of their functions or uses? Or do they refer to something more philosophical, like the different roles or perspectives within the crypto ecosystem? I'm keen to know more about how these mantles might shape the way we interact with and understand cryptocurrencies in today's financial landscape.
