Welcome to our guide on setting up a simple and pure Bitcoin Block Explorer that runs atop your full node! In this article, we’ll walk you through the process of deploying a block explorer that integrates with your Bitcoin Core node’s JSON-RPC interface, allowing you to view transaction and block information with ease.

What is a Bitcoin Node Block Explorer?

A Bitcoin Node Block Explorer is a web application that provides an interface to interact with your Bitcoin node. It enhances your ability to view all the transactions and blocks stored in your node without depending on any third-party sources. Instead, it taps directly into your node to fetch data, ensuring utmost reliability and authenticity.

Features of the Bitcoin Node Block Explorer

• Block Viewer: Displays all available block information, including an interactive hex viewer that shows the meaning of each byte in the headers and coinbase transactions.
• Transaction Viewer: Similar to the block viewer, it shows detailed information about every raw transaction with an interactive hex viewer.
• Universal Search: Input anything—transaction ID, block height, or raw transactions—and the explorer will display the relevant information.
• Mining Simulator: Create and simulate valid raw blocks while visualizing the mining process, including nonce adjustments and hash computations.
• Script Viewer: Step-by-step visualization of Bitcoin script interpretation.
• Direct JSON-RPC Interface: Communicate directly with your node to execute commands like getblock or getrawtransaction.
• Address Balances: Get the balance of a Bitcoin address if your node has address indexing enabled.

How to Run the Block Explorer

To run your own Bitcoin Block Explorer, follow these steps:

1. Ensure you have a fully built .war file of the project. You can connect to existing nodes, but running your own node is encouraged for a more reliable experience.
2. If you’re deploying it yourself, place the .war file in any J2EE web container (Jetty, Tomcat, etc.). If you need help with the process, let us know!
3. For a default setup, connect to srv1.yogh.io or srv2.yogh.io.

Building the Project

The following steps will walk you through building the project:

1. Clone the repository.
2. Run the command: mvn install
3. Locate the .war file in bitcoin-transactions-server/target.
4. Deploy the extracted .war file to your desired J2EE web container.
5. Congratulations! Your block explorer is ready.

Configuration

To configure the application, simply follow these steps:

1. Navigate to the web application.
2. Enter “config” into the search field and hit enter.
3. Follow the prompts to complete your configuration.

Understanding the Code Analogy

Imagine your Bitcoin Block Explorer as a sophisticated library filled with books (blocks) and chapters (transactions). Each time you want to find a book (block) or read a chapter (transaction), you don’t need to rely on a third-party librarian (external data source) who might misplace a book or miss an essential chapter. Instead, you access the library catalog (your Bitcoin node) directly, allowing you to browse titles (block and transaction IDs) and read chapters (raw transactions) without any hindrance.

Troubleshooting Tips

If you encounter issues while setting up your Bitcoin Node Block Explorer, try the following solutions:

• Ensure your Bitcoin node is fully indexed (use txindex=1) and functioning as a JSON-RPC server (server=1).
• Check if your firewall settings allow connections to the specified ports.
• If you run into configuration errors, double-check your entries in the configuration settings.

If the problem persists, consult the project repository for additional support.
