Every May, the crypto world laughs about the guy who traded 10,000 BTC for two Papa John’s pizzas. But reducing Laszlo Hanyecz to a mere "pizza guy" ignores one of the most critical engineering breakthroughs in Bitcoin’s history. Laszlo didn’t just spend Bitcoin; he fundamentally revolutionized how it was mined.
In early 2010, Bitcoin was a hobbyist project mined slowly on standard computer CPUs. Recognizing the inefficiency, Laszlo, a talented developer, rewrote Bitcoin’s source code to run on an NVIDIA graphics card (GPU). On May 10, 2010, he successfully deployed the world’s first GPU mining setup, unlocking unprecedented hashing power.
Instead of keeping this massive unfair advantage to himself, this true Bitcoin OG shared his code for free on the Bitcointalk forum. The impact was immediate and staggering. By the end of 2010, Bitcoin’s network hash rate exploded by over 130,000%, sparking the very first cryptographic arms race.
Just twelve days after his GPU code went live, he bought those infamous pizzas using his newly boosted mining rewards. The pizza proved Bitcoin worked as money, but his code ensured the network became secure enough to survive.
