Satoshi Nakamoto had pre-invented Bitcoin (BTC) GPU mining in order to defend the network, says early Bitcoin developer who worked with the Bitcoin creator in 2010.
Laszlo Hanyecz, who is known for making the first real-world Bitcoin transaction, has also been credited with inventing Bitcoin GPU mining. However, in a Cointelegraph interview, he said that not only Satoshi had invented it before him, but he also had several versions of the algorithm.
