1st: On January 3rd, 2009 Satoshi Nakamoto unleashed the Genesis Block into the wild. The Genesis Block contains the first 50 BTC block reward and cannot be spent by anyone. The bitcoin software was released on Sourceforge the web-based service for open source developers. The original Satoshi client was compiled using Microsoft’s visual studio and is written in the programming language C++. Satoshi began building the code in 2007 and was the only developer that made software changes to the bitcoin protocol up until mid-2010.

The first block also includes text from the UK Times newspaper saying “03/Jan/2009 Chancellor on brink of second bailout for banks,” a reference to bitcoin’s birth-date and possibly mocking fractional reserve banking.

2nd: The first BTC transaction sent between two people occurred on Jan 12, 2009 when Satoshi Nakamoto sent 50 BTC to Hal Finney in block 170. The cost of the transaction, like so many in the early days, was 0 BTC.

3rd: On May 22, 2010, now known as Bitcoin Pizza Day, Laszlo Hanyecz agreed to pay 10,000 Bitcoins for two delivered Papa John's pizzas. Organized on bitcointalk forum, the Florida man reached out for help.

"I'll pay 10,000 bitcoins for a couple of pizzas.. like maybe 2 large ones so I have some left over for the next day," Hanyecz wrote.

Bonus: In this art there are two hidden images, besides the main ones. One of them is the cover of The Times newspaper on January 3, 2009. The other is a @halfin post on January 10, 2009, which says "running bitcoin."
