Build Status Coverage Status

rusty-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 UTXDO dumps from Bitcoin based blockchains.

Currently Supported Blockchains:


It assumes a local copy of the blockchain with intact block index, downloaded with Bitcoin Core 0.15.1+. If you are not sure whether your local copy is valid you can apply

to validate the chain and block merkle trees. If something doesn't match the parser exits.


  • Callbacks

    Callbacks are built on top of the core parser. They can be implemented to extract specific types of information.

    : dumps all addresses with a non-zero balance. The csv file is in the following format:
    address ; balance

    : dumps all UTXOs along with the address balance. The csv file is in the following format:
    txid ; indexOut ; height ; value ; address
    NOTE: The total size of the csv dump is at least 8 GiB (height 635000).

    : dumps all parsed data as CSV files into the specified
    . See Usage for an example. I chose CSV dumps instead of an active db-connection because
    is the most performant way for bulk inserts. The files are in the following format:
    block_hash ; height ; version ; blocksize ; hashPrev ; hashMerkleRoot ; nTime ; nBits ; nNonce
    txid ; hashBlock ; version ; lockTime
    txid ; hashPrevOut ; indexPrevOut ; scriptSig ; sequence
    txid ; indexOut ; height ; value ; scriptPubKey ; address
    If you want to insert the files into MySql see sql/schema.sql. It contains all table structures and SQL statements for bulk inserting. Also see sql/views.sql for some query examples. NOTE: The total size of the csv dump is at least to 731 GiB (height 635000).

    : prints some blockchain statistics like block count, transaction count, avg transactions per block, largest transaction, transaction types etc.

You can also define custom callbacks. A callback gets called at startup, on each block and at the end. See src/callbacks/ for more information.

  • Low memory usage

    The required memory usage depends on the used callback:

    * simplestats: ~100MB
    * csvdump: ~100M
    * unspentcsvdump: ~18GB
    * balances: ~18GB

    NOTE: Those values are taken from parsing to block height 639631 (17.07.2020).

  • Script evaluation

    Evaluates and detects P2PK, P2PKH, P2SH and some non-standard transactions.

  • Resume scans

    can be passed to resume a scan. However this makes no sense for


This tool runs on Windows, OS X and Linux. All you need is


Latest Release

You can download the latest release from

cargo install rusty-blockparser

Build from source

git clone
cd rusty-blockparser
cargo build --release
cargo test --release
./target/release/rusty-blockparser --help

It is important to build with

, otherwise you will get a horrible performance!

*Tested on Gentoo Linux with rust-stable 1.44.1
