BTC Explorer

Simple, database-free Bitcoin blockchain explorer, via RPC. Built with Node.js, express, bootstrap-v4.

This tool is intended to be a simple, self-hosted explorer for the Bitcoin blockchain, driven by RPC calls to your own bitcoind node. This tool is easy to run but lacks features compared to full-fledged (stateful) explorers.

I built this tool because I wanted to use it myself. Whatever reasons one might have for running a full node (trustlessness, technical curiosity, etc) it's helpful to appreciate the "fullness" of a node. With this explorer, one can not only explore the blockchain (in the traditional sense of the term "explorer"), but also explore the capabilities of one's own node.

Features

• List of recent blocks
• Browse blocks by height, in ascending or descending order
• View block details
• View transaction details, with navigation "backward" via spent transaction outputs
• View raw JSON output used to generate most pages
• Search to directly navigate to transactions or blocks
• Mempool summary, showing unconfirmed transaction counts by fee level
• RPC Browser to explore all of the RPC commands available from your node
• RPC Terminal to send arbitrary commands to your node

Getting started

Prerequisites

1. Install and run a full, archiving node - instructions. Ensure that your node has full transaction indexing enabled (txindex=1) and the RPC server enabled (server=1).
2. Synchronize your node with the Bitcoin network.

Instructions

1. Clone this repo
2. npm install to install all required dependencies
3. Optional: Uncomment the "bitcoind" section in env.js to automatically connect to the target node.
4. npm start to start the local server
5. Navigate to http://127.0.0.1:3002/
6. Connect using the RPC credentials for your target bitcoin node (if you didn't edit env.js in Step 3)
