I mined block 70-something, and I was the recipient of the first #Bitcoin transaction when Satoshi sent ten coins to me as a test — I carried on an email conversation with #Satoshi over the next few days, mostly me reporting bugs and him fixing them.

#HalFinney was the first person to support and help Satoshi Nakamoto. He also contributed code in 2008 and early 2009, before it was released to the public in January 2009. Hal also went down in history as the receiver of the first Bitcoin transaction, in which Satoshi Nakamoto sent him 10 BTC.
