BTC RPC 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 (database-backed) 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, supporting the network, etc) it's helpful to appreciate the "fullness" of your node. With this explorer, you can not only explore the blockchain (in the traditional sense of the term "explorer"), but also explore the functional capabilities of your own node.

Live demos are available at:

LTC: https://ltc.chaintools.io

Features

List of recent blocks
Browse blocks by height, in ascending or descending order
View block details

Getting started

The below instructions are geared toward BTC, but can be adapted easily to other coins.

Prerequisites

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).
Synchronize your node with the Bitcoin network.

Instructions

Clone this repo
npm install to install all required dependencies
Edit the "rpc" settings in env.js to target your node
Optional: Change the "coin" value in env.js. Currently supported values are "BTC" and "LTC".
npm start to start the local server
