Bitcoin Pizza Day entered crypto folklore when programmer Laszlo Hanyecz decided that the first purchase using the revolutionary new financial technology – bitcoin – would be pizza. On May 22, 2010, through the bitcoin forum BitcoinTalk, Laszlo arranged for another forum participant to order two pizzas from Papa John's, and Laszlo would pay 10,000 BTC to cover the costs. The pizza was delivered to Laszlo's address, and the first transaction with bitcoin was recorded in history.
Considering the price of BTC at the time of writing, Laszlo paid over $595,000,000, which retrospectively became the most expensive pizza ever purchased.
Bitcoin Pizza Day is an important event as it was the first time real products were purchased with cryptocurrency. Since then, the industry has blossomed with thousands of different projects and cryptocurrencies using blockchain to revolutionize all aspects of culture, including fashion, art, music, real estate, telecommunications, and much more, but it all started with a whitepaper and two pizzas.
