What is flasher tool for cryptocurrency?

Could you elaborate on what the "flasher tool" refers to in the context of cryptocurrency? Is it a specific software, hardware, or perhaps a term related to mining, trading, or some other aspect of digital currencies? If it's a tool, what purpose does it serve? Does it aid in wallet management, mining efficiency, transaction verification, or something else entirely? I'm curious to understand the significance and functionality of this term in the cryptocurrency landscape. Clarifying its usage and application would be highly beneficial for those interested in this field.
