# bitcoin-explorer    `bitcoin_explorer` is an efficient library for reading bitcoin-core binary blockchain file as a database (utilising multi-threading). This package is ported using pyO3 from rust library `bitcoin-explorer` ### Installation MacOS, Windows, and Linux wheels are provided. Use `pip install bitcoin-explorer` to install. ## Documentation This library has a Rust version, go to [Rust Documentation](https://docs.rs/bitcoin-explorer/) For python documentation, go to [Documentation](https://congyuwang.github.io/Py-Bitcoin-Explorer/bitcoin_explorer.html). ## Compatibility Note This package deals with the binary file of another software `Bitcoin Core`. It might not be compatible with older Bitcoin Core versions. Currently, it is compatible with Bitcoin Core version `Bitcoin Core version v0.21.1.0-g194b9b8792d9b07***fdb570b79fa51f1d1f5ebaf Copyright (C) 2009-2020 The Bitcoin Core developers`. ## Examples It contains one class `BitcoinDB`. ```python import bitcoin_explorer as bex # parse the same path as `--datadir` argument for `bitcoind`. db = bex.BitcoinDB("~/Bitcoin") # get the length of the longest chain currently on disk. db.get_block_count() # get block of a certain height db.get_block(1000) # to retrieve the connected outputs of each inputs as well. # note that this is inefficient. # Use `get_block_iter_range(end, connected=True)` for better performance. db.get_block(1000, connected=True) # get block hash of a certain height. db.get_hash_from_height(1000) # a fast method for getting just the header. # in memory query, no disk access db.get_block_header(1000) # get block of height 1000. db.get_height_from_hash("some hash") # get transaction from txid. # This queries the `levelDB` each time, thus it is relatively slow. db.get_transaction("some txid") # get the height of the block which this transaction belongs. db.get_height_from_txid("some txid") # get the script type and addresses from a script public key db.parse_script("some hex script pubic key") # use iterator for block in db.get_block_iter_range(start=1000, end=2000): do_something_with(block) # use iterator, iterate over heights for block in db.get_block_iter_array(heights=[1, 3, 5, 7, 9]): do_something_with(block) # use iterator, connect outpoints # This requires 5 GB memory. for block in db.get_block_iter_range(end=700000, connected=True): do_something_with(block) ```
