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.
Write the binary block to a file.
Closes the stream.
Details
__construct(string $block, int|null $size = null, string|null $magicBytes = null)
Initialize a new instance of the bitcoin block parser class.
Generator
transactions()
Get the transactions.
int
weight()
The block weight.
bool
hasSegwit()
Check if the block contains any segregated witness transactions.
int
strippedSize()
Get the stripped size of the block, that is the size of the block without witness data.
int|float
difficulty()
Get the block difficulty.
int
transactionCount()
Get the transaction count.
string
blockHash()
Gets the block hash
int
nonce()
Get the block nonce.
int
bits()
Get the block bits.
string
bitsHex()
Get the block bits as hexadecimal.
int
timestamp()
Gets the block timestamp.
string
merkleRoot()
Gets the merkle root of the block.
string
previousBlock()
Gets the previous block hash.
int
version()
Gets the block version.
string
versionHex()
Gets the block version as hexadecimal.
string
block(bool $hex = false)
Gets the raw block.
Note that magic bytes and size variable are striped from the block.
int
size()
Gets the size of the block in bytes.
string|null
magicBytes()
Gets the magic bytes.
void
end()
Ends the reader and releases the underlying memory stream.
void
writeToFile(string $file)
Write the binary block to a file.
This will write the block to $file in the same format as when reading a blk file, [MagicBytes][Size][BlockData].
__destruct()
Closes the stream.
