# ![BTC Explorer](public/img/logo/btc-64.png) 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.
A live demo of the tool is available at https://btc-explorer.com
# 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 ](https://bitcoin.org/en/full-node ). 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 ](app/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 ](app/env.js ) in Step 3)
