Bitcoin Pizza is the name of the very first “real” transaction of Bitcoin for goods in physical life.
On May 22, 2010, a man named Laszlo Hanyecz negotiated with a counterparty to pay 10,000 BTC for two pizzas from Papa Johns. While there is a lot of unnecessary negative talk toward Laszlo for this act, it is important to remember that at the time of the transaction Bitcoin had no recognizable monetary value; and it is plausible to thank him for being the first individual to promote Bitcoin from just a niche cypherpunk theory into the real world of economics.
May 22, has become a holiday for the cryptocurrency community known as “Bitcoin Pizza Day”.
