Recently, I started researching the story behind the famous Bitcoin pizza purchase, and it turns out that most people have a pretty incomplete view of who Laszlo Hanyecz really was and what he did for Bitcoin in its early days.

Yes, everyone knows the story: in May 2010, Laszlo Hanyecz paid 10,000 BTC for two large Papa John’s pizzas. Today, that would be worth over a billion dollars. It’s the perfect headline anecdote, but what almost no one mentions is that Hanyecz spent nearly 10 times that amount afterward. According to his own records, between April and November 2010, he moved over 81,000 BTC from his original address, which would now be worth more than $8.6 billion.

But here’s the interesting part: before becoming an internet meme, Laszlo Hanyecz was literally a technical pioneer of Bitcoin. On April 19, 2010, just days after joining Bitcointalk, the forum founded by Satoshi Nakamoto, Hanyecz created the first macOS client for Bitcoin Core. At that time, Bitcoin only ran on Windows and Linux. His innovation allowed anyone with a Mac to run the software, laying the groundwork for all the Bitcoin wallets that support macOS today.

But that was not even close to his most important contribution. What Hanyecz did afterward completely revolutionized Bitcoin mining. He discovered that he could use his computer’s (GPU) graphics card to mine, which was much more efficient than using the (CPU) processor everyone had been using until then. On May 10, 2010, he posted on Bitcointalk: “I’ve updated the Mac OS X binary... It will use your GPU to generate bitcoin. This is really effective if you have a good GPU like an NVIDIA 8800.”

This innovation literally sparked the first digital gold rush. Bitcoin’s total hash rate skyrocketed by 130,000% by the end of that year. Suddenly, miners started building their first mining farms in basements, attics, and garages. Those small operations that Hanyecz helped inspire eventually evolved into the mega farms that dominate Bitcoin today.

Now, here’s where psychology comes into play. Satoshi wrote to Hanyecz expressing concern: “A big appeal for new users is that anyone with a computer can generate coins for free. But GPUs will limit that to only those with high-end hardware. It’s inevitable that GPU clusters will eventually corner the market on all coins, but I hope that doesn’t happen soon.” Hanyecz felt guilty. In a 2019 interview, he said: “I thought, ‘Oh my God, I feel like I’ve ruined his project. Sorry, buddy.’”

Perhaps that’s why he decided to do what he did afterward. He started spending Bitcoin massively, mainly on pizza according to his own comments. In February 2014, he wrote: “I spent all the Bitcoin I mined on pizza a long time ago. Aside from a little change, I spent everything I mined.” It’s not fully verifiable whether all of it was on pizza or if he also gave Bitcoin away to new Bitcointalk users, which was common when Bitcoin was practically worthless.

What’s fascinating is how Laszlo Hanyecz views all of this. In that 2019 interview, he explained his mindset with humor: “An exchange was made because both parties thought they were getting a good deal. I felt like I was winning at Internet, getting free food.” He said he felt like he had “hacked” the system, turning his electricity and computational power into free dinners. From his perspective, it was an absolute victory because at that moment he had no idea Bitcoin would have the value it has today.

That’s the full story of Laszlo Hanyecz. He’s not just the guy who spent a billion dollars on pizza. He’s the engineer who made Bitcoin work on macOS, who revolutionized mining with GPUs, who felt responsible enough for his impact to distribute massively what he had created. The pizza is just the ending of a much deeper story about technical contribution, ethical remorse, and the irony of how history remembers things.
