Bitcoin Transaction Explorer

Bitcoin Transaction Explorer is a browser-based Bitcoin block explorer that retrieves blockchain data from Bitcoin Core over JSON-RPC or from Blockr’s API. It searches and displays blocks and transactions, interprets raw data and scripts, and includes a mining simulator.

Practical overview

When it fits

Use it when you want to investigate Bitcoin blockchain structures, interpret raw data or follow script execution. For a self-hosted setup, build the WAR and deploy it to a J2EE container, then configure access to a suitable data source.

Who it is for

  • Bitcoin users who need to inspect blocks, transactions, serialized data or scripts.
  • Developers and node operators who want to run a browser-based explorer against Bitcoin Core.
  • Learners exploring how Bitcoin block construction and mining inputs affect a block hash.

Documented uses

  • Find a block by height or hash, or a transaction by ID.
  • Inspect block headers and transaction bytes with contextual hex views.
  • Interpret raw blocks, transactions and scripts.
  • Visualize nonce/extranonce changes, timestamp updates and block-hash computation.
  • Look up address balances when connected to a node with an address index.
Before you choose

Requirements & limits

The project is open source under the MIT license.

  • A Bitcoin Core connection requires JSON-RPC server configuration and a fully indexed node with txindex=1.
  • Blockr’s API is documented as an alternative data source.
  • Address balance lookup requires a node with an address index.
  • The explorer does not display fiat values or block and transaction receive times.
  • The application is built as a WAR for a J2EE web container.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Build and deploy the explorer

Package the web application as a WAR and deploy it to a J2EE web container.

Before you start

  • The project repository
  • Maven
  • A J2EE web container such as Jetty or Tomcat

Steps

  1. Clone the repository.

  2. Run mvn install.

  3. Locate the WAR file in bitcoin-transactions-server/target/.

  4. Deploy the WAR file to a J2EE web container.

Expected outcome

The explorer is deployed as a web application.

Guide limitations

  • This guide covers packaging and deployment, not configuring a Bitcoin node connection.
  • The README says a connected Bitcoin Core node must be fully indexed and configured as a JSON-RPC server.
