The alternative genesis block — Satoshi's pre-release test block from September 2008
SerHack published an analysis of a pre-release Bitcoin genesis block dated September 10, 2008 — discovered in source code Satoshi shared privately in November 2008. The test block had a completely different hash, trivially easy difficulty, and an initial block reward of 10,000 units. The September 10 date coincides with Lehman Brothers announcing $3.9 billion in losses.
