How many radiants exist?

Excuse me, could you clarify the context in which you're asking about "radiants"? Are you referring to a specific cryptocurrency, a unit of measurement within a blockchain protocol, or perhaps an entirely different concept altogether? If we're discussing a cryptocurrency or blockchain-related entity, it would be helpful to know the exact project or protocol in question. Without that information, I'm unable to provide a precise answer to your query, as the existence and number of "radiants" would depend on the specific context and application. Could you please elaborate further?
