Mining Companies

Ore is a proof-of-work token mining protocol implemented on the Solana blockchain. The protocol enables users to mine ORE tokens by computing and submitting valid hash solutions to the blockchain. Mining utilizes CPU and GPU hardware rather than application-specific integrated circuits, allowing participation with standard computing equipment. The protocol operates through the ore.supply platform and has released multiple versions, with version 2 introducing modifications to mining difficulty adjustment and reward distribution mechanisms.

Parasite Pool is a Bitcoin mining pool operating at parasite.space, where miners contribute hashrate and compete for block rewards using a shared-pool model. The pool tracks per-miner difficulty contributions, loyalty scores based on blocks participated, and leaderboard rankings, giving individual miners transparency into their relative performance. With a reported 1-day average hashrate of 1.15 EH/s and integration with the Sati and Xverse technology stack, the pool is designed to be accessible to a broad range of Bitcoin miners, from hobbyists to more substantial operators. The platform targets Bitcoin miners seeking a community-oriented pool with detailed on-chain statistics and compatibility with popular Bitcoin wallet infrastructure.

The company manufactures proprietary mining hardware, deploying over 5,552 machines for self-mining of Litecoin, Dogecoin, and Belenus. It provides Bitcoin hosting services with aggregate hash rate capacity of 2,082 PH/s. The company maintains a Solana token treasury and operates a validator node that generates staking rewards. SOLAI has issued DOLAI, a USD-backed stablecoin deployed on the Solana blockchain, developed in collaboration with Brale Inc. Core business operations encompass hardware manufacturing, data center hosting services, blockchain staking, and stablecoin issuance.

SOLminer.io was a blockchain company that operated a GPU-based cryptocurrency mining infrastructure at enterprise scale. The company's mining operation utilized graphics processing units for proof-of-work consensus mechanisms on GPU-mineable cryptocurrency networks, rather than ASIC-specific blockchains. The technical architecture centered on distributed GPU compute resources configured for mining operations. Current operational status and detailed product specifications are not publicly accessible.

Thumzup Media Corporation is a publicly traded company that operates a social media advertising platform enabling users to post branded content in exchange for compensation in cash or cryptocurrency. In August 2025, the company announced an acquisition of Dogehash, a Dogecoin mining operation, representing a strategic shift toward cryptocurrency mining infrastructure.
