Best On-Premises Blockchain Explorers of 2025

This is a self-hosted tool designed to explore the Bitcoin blockchain, utilizing RPC calls to connect with your personal Bitcoin node. It is straightforward to set up and can be integrated with other applications, such as Electrum servers, to create a comprehensive exploration platform. Regardless of whether you run a full node for reasons like trustlessness, technical interest, or network support, it is essential to recognize the capabilities that your node offers. This explorer allows you to delve into the blockchain database while also taking advantage of the various functionalities provided by your own node. You can inspect detailed information regarding blocks, transactions, and addresses, while also utilizing analytical tools to review statistics on block data, transaction metrics, and miner performance. Additionally, you can access the raw JSON output from bitcoind that populates most of the explorer's pages. The tool enables searches by transaction ID, block hash or height, and address. Furthermore, users have the option to retrieve transaction history for addresses by querying Electrum-protocol servers, and it provides a summary of the mempool, detailing aspects such as fees, sizes, and the age of transactions. With such extensive features, this explorer serves as a robust resource for both casual users and those deeply engaged in the Bitcoin network.

Creating a mempool and blockchain explorer tailored for the Bitcoin community emphasizes the transaction fee market and the multi-layer ecosystem while eschewing any form of advertising, altcoins, or external tracking services. This mempool can be set up on an array of personal hardware, offering options from an easy one-click installation on a Raspberry Pi to a robust high-availability cluster designed for enterprise-level deployment. Additionally, this platform aims to provide users with complete control and transparency over their blockchain interactions.
