Hi there,
I'm looking at the block header information on this page:
https://en.bitcoin.it/wiki/Block_hashing_algorithmIt covers the following block header fields:
Version
hashPrevBlock
hashMerkleRoot
Time
Bits
Nonce1. Are these the exact field names used in the protocol, or are these just descriptive names for the purposes of the article?2. A question about the Bits field.When hashing the block header in the example PHP code at the bottom of the bitcoin wiki page, the value used for
Bits is
440711666.
However, when looking at the block information (
http://blockexplorer.com/b/125552), the value they have displayed for
Bits is
Difficulty?: 244 112.487774 ("Bits"?: 1a44b9f2)How do I convert the difficulty/bits information displayed on blockexplorer to
440711666?
