The skalds of Bitcoin Twitter have sung<\/a> of the historic moment, the \u201cfirst real world purchase\u201d with bitcoin, and pundits have etched the story into the internet\u2019s memory with headlines<\/a> about the infamous Bitcoin Pizza Purchase, now dearly valued at more than $1 billion.<\/p>\n

But what if I told you that Hanyecz spent nearly 10 times more bitcoin following the historic purchase? And, what if I told you that perhaps Hanyecz did so as ostensible penance for his much more consequential contribution to Bitcoin in its uncertain infancy?<\/p>\n

He was a Bitcoin technical pioneer<\/h2>\n

The penumbra of Hanyecz\u2019s Pizza Day purchase has overshadowed his two seminal contributions to Bitcoin\u2019s early technical development.<\/p>\n

This post originally appeared on Blockspace Media, where Colin Harper is editor-in-chief. <\/em><\/strong><\/a><\/p>\n

The first of these came on April 19, 2010, just days after Hanyecz registered for Bitcointalk, a forum established by Satoshi Nakamoto that was (and still is) a watering hole for Bitcoin\u2019s techie intelligentsia. Hanyecz created the first MacOS client for Bitcoin Core, the original and still-dominant software implementation for the nodes that underpin the Bitcoin network.<\/p>\n

Satoshi originally coded Bitcoin for Windows and Linux, but Hanyecz\u2019s innovation enabled MacOS devices to run the software too. His contribution laid the foundation for all MacOS-enabled bitcoin wallets and applications that would follow it.<\/p>\n

But arguably greater than this was Hanyecz\u2019s discovery that he could mine bitcoin with his computer\u2019s graphics card (GPU). Until this point, early adopters used their computer processing units (CPUs) to mine bitcoin, and since GPUs are orders of magnitude more powerful than CPUs for the task, this innovation propelled bitcoin mining forward much faster than Satoshi expected.<\/p>\n

\u201cUpdated Mac OS X binary\u2026It will use your GPU to generate bitcoins. This works really well if you have a good GPU like an NVIDIA 8800 or something like that,\u201d Hanyecz wrote in a May 10, 2010 Bitcointalk post<\/a>.<\/p>\n

The discovery ignited Bitcoin\u2019s first digital gold rush. Bitcoin\u2019s total hashrate exploded upward by 130,000% by the end of the year<\/a>, and for the first time, bitcoin miners began constructing small-scale mining farms. These setups \u2013 slapped together in basements and attics, garages and sheds \u2013 were the prototypes for the industrial-scale bitcoin mining farms that dominate the Bitcoin network today.<\/p>\n

The Pizza was penance<\/h2>\n

Hanyecz\u2019s invention was so consequential that it earned him a virtual drop in from Satoshi Nakamoto himself. And it\u2019s possible that the conversation that followed may have inspired Hanyecz\u2019s famous Pizza Day purchase.<\/p>\n

\u201cA big attraction to new users is that anyone with a computer can generate some free coins,\u201d Satoshi wrote <\/a>to Hanyecz. \u201cGPUs would prematurely limit the incentive to only those with high-end GPU hardware. It\u2019s inevitable that GPU compute clusters will eventually hog all the generated coins, but I don\u2019t want to hasten that day.\u201d<\/p>\n

In a 2019 interview<\/a> for Bitcoin Magazine, Hanyecz told me that he \u201cstopped advertising [GPU mining] after that.\u201d<\/p>\n

\u201cI was like, \u2018Man, I feel like I crapped up your project. Sorry, dude.\u2019 He was concerned that some people might be discouraged because they can\u2019t mine a block with a CPU,\u201d Hanyecz said.<\/p>\n

Perhaps this conversation spurred Hanyecz to offer 10,000 BTC for two large Papa John\u2019s pizzas on that fateful day in May 15 years ago. In fact, he made the offer more than once. During the 2019 interview, Hanyecz told me that he spent nearly 100,000 BTC in the year that followed.<\/p>\n

\u201cI spent [all my bitcoin] on pizza long ago,\u201d Hanyecz wrote in a February 2014 Bitcointalk post<\/a>. \u201cOther than a little bit of single digit change, I spent everything I mined. As you all know, the difficulty rises to adjust to hashing power, so eventually the mining wasn’t worth it for me.\u201d<\/p>\n

Looking at a Bitcoin address Hanyecz listed on his first Bitcointalk post, Hanyecz received and spent 81,432 BTC from this address from April to November 2010. This sum would be worth just over $8.6 billion today.<\/p>\n

There\u2019s no way to verify if Hanyecz spent all of this on pizza, other goods, or if he simply gave bitcoin away to new Bitcointalk members, a common practice back then when bitcoin was close-to worthless. But he did mention in his original thread for the pizza purchase that it was \u201can open offer,\u201d although he reneged on<\/a> this in August saying, \u201cI can’t really afford to keep doing it since I can’t generate thousands of coins a day anymore. Thanks to everyone who bought me pizza already.\u201d<\/p>\n

The original purchase, let alone the recurring ones that apparently occurred after, would be enough to keep any sane person awake at night as bitcoin marches above $100,000. But in 2019 at least, Hanyecz stomached the ordeal with good humor. As he saw it, he committed culinary alchemy, transmuting his electricity and computing power into a cheap dinner. He had no idea that bitcoin would command the price it does today, so the transaction was a victory in his book.<\/p>\n

\u201cA trade happens because both parties think they\u2019re getting a good deal,\u201d he said. \u201cI felt like I was beating the internet, getting free food. I was like, \u2018Man, I got these GPUs linked together, now I\u2019m going to mine twice as fast. I\u2019m just going to be eating free food; I\u2019ll never have to buy food again…” <\/p>\n

“I mean, I coded this thing and mined bitcoin and I felt like I was winning the internet that day. I got pizza for contributing to an open-source project. Usually hobbies are a time sink and money sink, and in this case, my hobby bought me dinner.\u201d<\/p>\n
