Bitcoin Research Kit

Open-source on-chain analytics for Bitcoin. Combines functionality of Glassnode (on-chain metrics), mempool.space (block explorer), and electrs (address index) into a single self-hostable package. Bitview is an analytics interface built entirely on BRK.

Data

Blockchain — Blocks, transactions, addresses, UTXOs.

Metrics — Supply distributions, holder cohorts, network activity, fee markets, mining, and market indicators (realized cap, MVRV, SOPR, NVT).

Indexes — Date, height, halving epoch, address type, UTXO age.

Mempool — Fee estimation, projected blocks, unconfirmed transactions.

Usage

API

Query thousands of metrics and blockchain data in JSON or CSV. Use it free at Bitview, no signup required.

Documentation · Clients: JavaScript, Python, Rust · MCP

Self-host

Compute all metrics locally. Private, verifiable, self-sovereign. Runs alongside Bitcoin Core.

Guide

Library

Build custom applications in Rust. Use the full stack or individual components (parser, indexer, computer, server).
