bitcoin-blockparser

bitcoin-blockparser is a Bitcoin Blockchain Parser written in Rust language.

It allows extraction of various data types (blocks, transactions, scripts, public keys/hashes, balances, ...) and UTXO dumps from Bitcoin based blockchains.

This is a fork of the rusty-blockparser crate, which also contains support for other cryptocurrencies.

Currently Supported Blockchains:

Bitcoin and BitcoinTestnet3.

IMPORANT: It assumes a local unpruned copy of the blockchain with intact block index and blk files, downloaded with Bitcoin Core 0.15.1+ or similar clients. If you are not sure whether your local copy is valid you can apply --verify to validate the chain and block merkle trees. If something doesn't match the parser exits.

Usage

Usage: bitcoin-blockparser [OPTIONS]

Options:
      --verify
          Verifies merkle roots and block hashes
  -v...
          Increases verbosity level. Info=0, Debug=1, Trace=2 (default: 0)
  -c, --coin <NAME>
          Specify blockchain coin (default: bitcoin) [possible values: bitcoin, testnet3]
  -d, --blockchain-dir <blockchain-dir>
          Sets blockchain directory which contains blk.dat files (default: ~/.bitcoin/blocks)
  -s, --start <HEIGHT>
          Specify starting block for parsing (inclusive)
  -e, --end <HEIGHT>
          Specify last block for parsing (inclusive) (default: all known blocks)
  -h, --help
          Print help
  -V, --version
          Print version

Installing

This tool should run on Windows, OS X and Linux. All you need is rust and cargo.

Latest Release

You can download the latest release from crates.io:

cargo install bitcoin-blockparser

Build from source

git clone https://github.com/dspicher/bitcoin-blockparser.git
cd bitcoin-blockparser
cargo build --release
cargo test --release
./target/release/bitcoin-blockparser --help

It is important to build with --release, otherwise you will get a horrible performance!

Tested on Gentoo Linux with rust-stable 1.44.1

Supported Transaction Types

Bitcoin and Bitcoin Testnet transactions are parsed using rust-bitcoin, this includes transactions of type P2SH, P2PKH, P2PK, P2WSH, P2WPKH, P2TR, OP_RETURN and SegWit.
