What mempool space does

mempool.space is an open-source Bitcoin mempool explorer and blockchain visualization platform operated by Mempool Holdings S.A. de C.V. and headquartered in Osaka, Japan. The core product provides real-time visualization of pending Bitcoin transactions, blocks, fee estimation across multiple priority levels (No, Low, Medium, High Priority), Lightning Network node and channel statistics, mining pool distribution and hashrate metrics, and transaction acceleration services. It supports Mainnet, Testnet3, Testnet4, and Signet networks and runs on self-hosted bare-metal infrastructure deployed across six globally distributed data centers with its own ISP and minimal software dependencies. The platform's public-facing explorer at mempool.space serves millions of users and processes 150 million API calls daily, with proprietary features including Mempool Goggles® (transaction categorization by type such as Consolidation, Coinjoin, and Data) and Mempool Accelerator (stuck transaction prioritization via direct mining pool submission).

The business operates a two-tier go-to-market model. The free public tier supports individual Bitcoin users, developers, and self-hosters who deploy the open-source software via Umbrel, RaspiBlitz, myNode, RoninDojo, StartOS, and other node platforms. The paid Mempool Enterprise® tier targets Bitcoin businesses with tiered monthly subscriptions (Silver $1,499, Gold $2,999, Platinum $5,999) providing unmetered REST API access, Electrum RPC, WebSockets, Accelerator Pro, and SLAs ranging from 99.9% to 99.99%. Named enterprise customers include Unchained, Bitkey (Block), Zaprite, BitMEX, and Foundry, and the project is sustained by a sponsorship ecosystem spanning core, major, and minor enterprise and community tiers with 60+ Bitcoin companies including Spiral, Blockstream, Metaplanet, Bull Bitcoin, Fortris, Exodus, Gemini, Onramp Bitcoin, Cake Wallet, Leather, and Taproot Wizards. Revenue is not publicly disclosed; the company received an undisclosed funding round from Ten31 in September 2022.

Scale indicators6 records

Recent moves4 records

Expansion highlights6 records

Broad incumbents

• Glassnode: Established Bitcoin and multi-chain on-chain analytics platform serving institutional clients with dashboards, APIs, and research. Competes with Mempool's enterprise tier for institutional Bitcoin data spend at a much larger scale and broader analytical scope.
• CryptoQuant: Institutional on-chain analytics platform offering exchange flow, miner, and network data with API access. Targets the same enterprise Bitcoin/crypto customer base that buys Mempool Enterprise, though with a broader multi-chain and trading-oriented feature set.

Direct peers

• 1ML: Lightning Network explorer and node directory providing node rankings, channel statistics, and liquidity information. Directly comparable to mempool.space's Lightning Explorer module for both retail and enterprise Lightning analytics use cases.
• Blockchair: Multi-chain block explorer offering Bitcoin and other chain analytics with API access and SQL-style query tooling. Competes with mempool.space for blockchain data API customers across similar Bitcoin-first developer and analyst audiences.
• Blockchain.com: One of the longest-running Bitcoin block explorers and a major centralized wallet/exchange. Operates a comparable block explorer with transaction tracking and fee data, directly competing with mempool.space for end-user exploration traffic and developer mindshare.
• Amboss: Lightning Network explorer and node management platform offering node analytics, Magma marketplace, and enterprise tooling. Competes directly with Mempool's Lightning Explorer for both consumer and institutional Lightning data customers.
• btc.com: Bitcoin block explorer and mining pool statistics platform owned by Bit Mining. Provides transaction tracking and pool/hashrate analytics comparable to Mempool's Mining Dashboard, with similar target users in mining and trading.
• Blockstream Esplora: Blockstream's open-source self-hosted Bitcoin block explorer (the codebase mempool.space was originally forked from). Operates blockstream.info and ships Esplora as the default explorer on Liquid Network and many self-hosted Bitcoin nodes — a direct functional and architectural peer.

Others

• Alchemy: Dominant multi-chain blockchain developer infrastructure platform (node API, indexing, webhooks) serving Web3 builders. While primarily Ethereum-centric, Alchemy is the closest analog to where Mempool Enterprise is heading in the Bitcoin ecosystem — production-grade blockchain APIs for application developers.

Emerging players

• BTCPay Server: Open-source Bitcoin payment processor widely integrated with mempool.space. While not a direct explorer competitor, BTCPay overlaps with Mempool at the infrastructure layer for self-hosted Bitcoin businesses and shares the same open-source, self-sovereign philosophy.
