Who is Satoshi Nakamoto?
Satoshi Nakamoto is the original creator of Bitcoin. It turns out that the name is just a pseudonym, and no one really knows who Nakamoto is. He, she or they might be a single individual or a group of developers who worked together on the project.
Over the years, many people have claimed to be Satoshi for one reason or another. To date however, no one has provided any sort of verifiable proof to back up such claims. Thus, we still do not know who the elusive Satoshi Nakamoto is. We don't even know if Nakamoto is still alive at this point.
Being the founder of Bitcoin, a bitcoin’s smallest denomination was named after him as an homage: the satoshi. A single satoshi or sat is equal to 0.00000001 bitcoin or BTC. If it helps you to better understand, one satoshi is to one bitcoin what one penny is to one million Canadian dollars.
