BlockParser
class BlockParser (View source)
BlockParser reads the raw block data extracted from blk files.
NOTE: These requires knowledge of more than just one block in the chain, this is not a db just a reader/parser.
- height (
calculated based on knowing the prev block hash back to genesis.) - confirmations (
total blocks - height) - median time (
MEDIAN([time, of, past, 11, blocks])) - chain work (
requires knowledge of the prev blocks chain work) - next block hash (
it's in the name we need the next block in the chain to tell us)
Properties
| protected Stream | $block | The block bytes we read from. |
|
| protected string|null | $magicBytes | The magic bytes that indicates the block start and type. |
|
| protected int|null | $size | The block size. |
Methods
Initialize a new instance of the bitcoin block parser class.
Get the transactions.
The block weight.
Check if the block contains any segregated witness transactions.
Get the stripped size of the block, that is the size of the block without witness data.
Get the block difficulty.
Get the transaction count.
Gets the block hash
Get the block nonce.
Get the block bits.
Get the block bits as hexadecimal.
Gets the block timestamp.
Gets the merkle root of the block.
Gets the previous block hash.
Gets the block version.
Gets the block version as hexadecimal.
Gets the raw block.
Gets the size of the block in bytes.
Gets the magic bytes.
Ends the reader and releases the underlying memory stream.
Closes the stream.
