On May 10, 2010, developer Laszlo Hanyecz published a post on the Bitcointalk forum explaining how to mine Bitcoin using an NVIDIA 8800 GTS graphics card instead of a CPU. Exactly 16 years later, the episode is still tied to a major shift in Bitcoin’s network activity: it helped drive the network’s hash rate up by 130,000% by the end of that year.
The moment is also notable for what it changed in Bitcoin’s underlying philosophy. In mainstream culture, Hanyecz is often described as the man who invented GPU mining and later bought two pizzas for 10,000 BTC. Less widely discussed is Satoshi Nakamoto’s reaction to Hanyecz’s success.
After learning about the GPU mining results, Satoshi reportedly asked Hanyecz to slow down the popularization of the method. The concern was that Bitcoin was intended to operate as a system of “one CPU, one vote,” enabling anyone with a home computer to support the network and receive rewards.
The transition to graphics cards disrupted that balance. According to the article, ordinary PC users lost virtually any chance of mining a block, and mining evolved from ideological participation into a hardware competition—concentrating mining power among those able to afford expensive graphics chips.
From a technical standpoint, the article attributes the change to code optimization for OpenCL and CUDA architectures. Hanyecz’s original post is cited with specific performance figures from a single home setup:
The article also states that combining CPU and GPU allowed Hanyecz to capture a substantial share of the network’s blocks, mining thousands of coins per day on a single computer.
Looking back, the article argues that Hanyecz’s invention did not “break” Bitcoin. Instead, it says the shift accelerated Bitcoin’s maturation, and that without the move toward GPU mining, the network likely would not have survived later waves of users or defended itself against potential attacks.
