Title: How to download Bitcoin block headers (6 input parameters) as file ? Post by: darius2020 on January 22, 2014, 01:06:21 PM Hi,
Tell me how to download Bitcoin block headers (6 input parameters) parsed as csv data file ? I run Javascript Bitcoin block hashing demo application and plan to run it for every block hashed in the past to verify nonce. Any idea ? What I need are 6 Bitcoin block header raw input parameters as defined by https://en.bitcoin.it/wiki/Block_hashing_algorithm (https://en.bitcoin.it/wiki/Block_hashing_algorithm) Quote Field Purpose Updated when... Size (Bytes) Version Block version number You upgrade the software and it specifies a new version 4 hashPrevBlock 256-bit hash of the previous block header A new block comes in 32 hashMerkleRoot 256-bit hash based on all of the transactions in the block A transaction is accepted 32 Time Current timestamp as seconds since 1970-01-01T00:00 UTC Every few seconds 4 Bits Current target in compact format The difficulty is adjusted 4 Nonce 32-bit number (starts at 0) A hash is tried (increments) 4 so data only parsed. Tried Blockexplorer http://blockexplorer.com/block/00000000000000001e8d6829a8a21adc5d38d0a473b144b6765798e61f98bd1d (http://blockexplorer.com/block/00000000000000001e8d6829a8a21adc5d38d0a473b144b6765798e61f98bd1d) Unfortunately block header 6 parameters are not parsed, too much ASCII text. any help ? |
