Some early OG’s that can help me out? I remember mining in 2008 with a quite sophisticated client on Windows, it had an address book and showed connections in the status bar. I’ve also read some paper from usenet about a digital currency. But the Bitcoin Whitepaper is from October 31, 2008, which could check out, but the first block was mined Janurary 3, 2009. The client looked odfully similar to bitcoin-qt, but that one was released on 21 November 2011, so what was I mining at that time?
