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