This page is a stub. Help by expanding it.
A genesis block is the first block of a block chain. Modern versions of Bitcoin assign it block number 0, though older versions gave it number 1.
Main network genesis block
The block on Bitcoin Block Explorer
Here is a representation of the genesis block as it appeared in a comment in an old version of Bitcoin (line 1613). The first section defines exactly all of the variables necessary to recreate the block. The second section is the block in standard printblock format, which contains shortened versions of the data in the first section.

vMerkleTree: 4a5e1e
The coinbase parameter (seen above in hex) contains, along with the normal data, the following text[1]:
The Times 03/Jan/2009 Chancellor on brink of second bailout for banks
This was probably intended as proof that the block was created on or after January 3rd, 2009, as well as a comment on the instability caused by fractional-reserve banking.
The first 50BTC block reward went to address 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa and has yet to be spent (2011-03-04).
