bitcoin-blockchain-parser

This Python 3 library provides a parser for the raw data stored by bitcoind.

Features

• Detects outputs types
• Detects addresses in outputs
• Interprets scripts

Examples

import sys
from blockchain_parser.blockchain import Blockchain

# Instantiate the Blockchain by giving the path to the directory 
# containing the .blk files created by bitcoind
blockchain = Blockchain(sys.argv[1])
for block in blockchain.get_unordered_blocks():
    for tx in block.transactions:
        for no, output in enumerate(tx.outputs):
            print("tx=%s outputno=%d type=%s value=%s" % (tx.hash, no, output.type, output.value))

# To get the blocks ordered by height, you need to provide the path of the
# `index` directory (LevelDB index) being maintained by bitcoind. It contains
# .ldb files and is present inside the `blocks` directory
for block in blockchain.get_ordered_blocks(sys.argv[1] + '/index', end=1000):
    print("height=%d block=%s" % (block.height, block.hash))
