What is 1 Nakamoto?

Could you please explain to me in simple terms what exactly is meant by '1 Nakamoto'? Is it a unit of currency or a token related to the world of cryptocurrency? I've heard it mentioned in some circles, but I'm not entirely sure of its significance or value. Is there a specific blockchain or cryptocurrency that it's tied to? How does it compare to other popular units of measurement like Bitcoin or Ethereum? I'm eager to learn more and understand its place in the broader cryptocurrency ecosystem.
