Rusty Blockparser

Rusty Blockparser is a Rust command-line program that parses local blockchain files to extract blocks, transactions, scripts, public keys or hashes, balances and UTXO data. Its commands can produce CSV files, display selected OP_RETURN data and report blockchain statistics. It supports Bitcoin, Bitcoin Testnet and several named Bitcoin-derived chains.

Practical overview

When it fits

Use it when you have a local, unpruned copy of a supported chain and want to extract or summarize its stored block data from the command line.

Who it is for

  • Developers building local blockchain data extraction pipelines.
  • Researchers or analysts who need CSV records, address balances, UTXOs or chain statistics.
  • Rust developers adapting the parser or its callbacks for tailored extraction.

Documented uses

  • Export balances for addresses with non-zero balances to CSV.
  • Dump unspent transaction outputs with associated address balances.
  • Export block, transaction, input and output data as CSV for subsequent analysis or database import.
  • Inspect valid UTF-8 OP_RETURN contents and calculate basic blockchain statistics.
  • Extend callbacks or customize the parser for a coin.
Before you choose

Requirements & limits

The project is open source under GPL-3.0. The README identifies GitHub as its official source for releases and describes builds for Windows, macOS and Linux.

  • Requires an unpruned local blockchain copy with an intact block index and block files; Bitcoin Core 0.15.1 or a similar client is specified.
  • Available chain options include Bitcoin, Testnet, Namecoin, Litecoin, Dogecoin, Myriadcoin, Unobtanium and NoteBlockchain.
  • The README estimates around 18 GB of memory for balance and UTXO extraction, versus about 100 MB for statistics and full CSV parsing; figures are tied to a historical block height.
  • The README says a full CSV dump can reach at least 731 GiB at its cited historical height; a UTXO dump can reach at least 8 GiB.
  • Bitcoin and Bitcoin Testnet transaction parsing and the custom script handling for Bitcoin forks have different documented transaction-type coverage.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Build Rusty Blockparser from source

Prepare the command-line program from the GitHub repository.

Before you start

  • Rust and Cargo
  • A clone of the official repository

Steps

  1. Clone https://github.com/gcarq/rusty-blockparser.git.

  2. Change into the rusty-blockparser directory.

  3. Build the release version with cargo build --release.

  4. Run cargo test and then ./target/release/rusty-blockparser --help as listed in the README.

Expected outcome

A release build and the command-line help output, following the repository's documented setup sequence.

Guide limitations

  • The guide covers building and displaying help, not parsing a blockchain.
  • The README says release mode is essential for performance and reports testing on Gentoo Linux with rust-stable 1.85.0.
