Mining Companies

DMND is a Bitcoin mining pool operated by Guru Protocol Ltd, registered in England and Wales and headquartered in London. The pool is built natively on the Stratum V2 protocol, an end-to-end encrypted binary mining protocol that enables miner-side block template selection, giving individual miners control over which transactions they include in blocks rather than delegating that choice to the pool. DMND uses a proprietary payout scheme called SLICE, a variant of PPLNS with job declaration, designed to provide transparent and verifiable earnings distribution. The pool holds SOC 2 Type 2 compliance certification and targets both enterprise-scale mining operations and high-efficiency solo operators seeking security, privacy, and decentralization.

FutureBit is a Brooklyn, New York-based hardware manufacturer specializing in home-use Bitcoin mining and full-node devices. The company produces the Apollo product line, including the Apollo II, Apollo III, and the Solo Node, which combine Bitcoin ASIC mining hardware with integrated full-node software in compact, consumer-friendly form factors. Its products are designed for individual hobbyist and solo miners seeking to participate in Bitcoin mining and network validation without industrial-scale infrastructure. FutureBit differentiates itself by targeting the retail segment with plug-and-play devices that run a proprietary operating system, Apollo OS, enabling users to mine and run a Bitcoin node from a single unit starting at accessible price points.

GorillaPool is a Bitcoin SV (BSV) mining pool that offers pooled hash power aggregation, managed ASIC hosting, and blockchain infrastructure services. The pool charges a 2% fee with daily payouts and operates enterprise-grade infrastructure targeting 99.9% uptime, serving both independent ASIC miners and larger mining operations. A technical differentiator is its collaboration with the Teranode team, aimed at scaling BSV block processing beyond current limits, alongside its proprietary JungleBus blockchain indexer and overlay engine and Arc transaction ingestion service. The platform positions itself as an ISP-like infrastructure layer on BSV, also offering ASIC hardware sales and industrial-rate electricity hosting for managed mining customers.

Greenidge Generation Holdings is a vertically integrated bitcoin mining and power generation company that operates natural gas power plants to supply electricity directly to its on-site mining operations. Its primary facility is located in Dresden, New York, with expansion plans including a South Carolina plant. The company differentiates itself by owning its own power generation infrastructure, which it claims enables carbon-neutral bitcoin mining through renewable energy offsets and efficiency measures. It also markets a modular mining product called Pod X for third-party deployment. Greenidge is publicly traded and has been covered by Reuters, Bloomberg, and CoinDesk for its environmental positioning within the mining sector.

Hashbranch is a U.S.-based Bitcoin mining platform that provides ASIC hardware brokerage and managed hosting services for individual and institutional users. The platform connects purchased or existing mining hardware to hosting facilities based on yield and operational criteria, and coordinates procurement, deployment, billing, and ongoing monitoring through a centralized dashboard. Its system includes fleet management features such as 24/7 monitoring, hardware resale, and relocation of mining equipment when hosting conditions change. It also provides advisory services related to mining operations and infrastructure selection. Hashbranch reports operational metrics including deployed ASICs, hosting capacity measured in megawatts, and platform users. It has also been involved in partnerships with mining operators such as Merkle Standard to support large-scale Bitcoin mining deployments.

Hashpower is a power and infrastructure development company focused on Bitcoin mining and decentralized finance infrastructure, converting raw computing power into network security and real-world value. The company frames its work through an Austrian School economics lens and draws on proof-of-work theory, including the cybersecurity arguments advanced in Major Jason Lowery's SoftWar thesis, to position hashpower as a broader information-security primitive beyond finance. Its target audience includes Bitcoin-aligned investors, infrastructure operators, and institutions interested in decentralized compute and energy-backed mining operations. The company operates under the domain hashpower.energy and has received venture backing to advance decentralized mining and AI infrastructure development.

iBeLink is an ASIC miner manufacturer and retailer specializing in hardware for mining Kaspa, Kadena, and CKB (Nervos) cryptocurrencies.
