Blockstream has overhauled its Bitcoin and Liquid block explorer for the first time since the original version launched in November 2018. The redesigned tool transforms what was essentially a blockchain search engine into something closer to a network command center, featuring live mempool visualizations, fee recommendations, and a dedicated dashboard for the Liquid network.

The explorer remains freely accessible at blockstream.info and continues to be built on the open-source Esplora framework. However, nearly everything layered on top of that foundation has been rethought. The update lands in a category where Blockstream's explorer competes with other free, popular alternatives such as mempool.space and BTC.com, which have long offered live mempool visualizations and fee estimation — features the previous Blockstream interface lacked, making this rebuild a catch-up as much as a leap forward.

What the New Explorer Offers

The most visually striking addition is a live next-block mempool visualization, in which pending transactions appear as colored tiles sized according to their virtual size and color-coded by fee band. For everyday users, this matters most when the network is congested: during high-demand periods, fee markets determine whether a transaction confirms in the next block or waits hours, and visualizing the queue of pending transactions helps users judge whether the suggested fee is worth paying or waiting out.

The redesigned dashboard consolidates a range of metrics that previously required switching between multiple tools. Time since the last block, suggested transaction fees shown in both sat/vB and their USD equivalents, and mempool congestion gauges are all now available on the main page.

Price charts are integrated as well, so users no longer need to cross-reference a separate site to contextualize on-chain activity against market movements.

For the Liquid network, Blockstream's federated sidechain, the explorer now includes a dedicated health view. This dashboard highlights key asset metrics, transaction volumes, and network statistics specific to Liquid. It also supports tracking of peg-in and peg-out transactions — the mechanism by which Bitcoin moves between mainnet and the Liquid sidechain — as well as confidential transactions that obscure amounts and asset types.

The explorer covers Bitcoin mainnet and testnet alongside Liquid mainnet and testnet, offering a single pane of glass for developers working across both networks.

Built for Developers, Not Just Browsers

Notably, every page in the new explorer is powered by the same public Blockstream Explorer API that third-party applications already use. The dashboard does not draw on any hidden internal data source; any metric visible on the explorer can be accessed programmatically for use in third-party applications. This matters because block explorer APIs are core infrastructure for wallets, payment processors, and analytics tools — if the public API and the public website are the same, what developers see is exactly what users see, with no gated data tier.

The new version also adds enhanced tracking of SegWit versus legacy transaction fee savings. SegWit, the protocol upgrade activated on Bitcoin in 2017 that restructured how transaction data is measured, typically allows users to pay lower fees. Surfacing those savings directly in the explorer gives users a concrete reason to ensure their wallets support the newer format.

Privacy as a Feature, Not a Footnote

The site operates as a no-tracking, privacy-oriented public resource, meaning it does not harvest user data or build advertising profiles from search queries. This stands in contrast to many commercial explorers that monetize traffic, and it aligns with the expectations of Bitcoin users for whom querying an address can itself be a privacy-sensitive act — third parties observing those queries could otherwise link addresses to the person searching them.

The Liquid-specific privacy tools add another layer. Confidential transactions on Liquid hide the amounts and asset types being transferred, and the explorer is designed to respect and display these transactions without undermining their privacy properties.

The original Blockstream Explorer launched in November 2018 alongside the Liquid Network itself. What differentiates Blockstream's offering is the dual coverage of both Bitcoin and Liquid from a single interface, combined with an API-first architecture that makes every displayed metric available programmatically. Worth watching next is whether third-party applications begin building on the newly exposed metrics — and whether competitor explorers respond with deeper sidechain coverage of their own.
