Most people think of cryptocurrency mining as a single-coin activity. Machines are acquired, pointed at the Bitcoin network, and run to generate rewards. The equation feels intuitive – Bitcoin is the asset people want, so Bitcoin is what is mined.
When the economics of that arrangement compress, as they have since the April 2024 halving, there is limited flexibility. The hardware is locked to one algorithm, the algorithm points at one network, and the margin pressure is absorbed rather than avoided.
This is the model that most of the mining industry still operates on. It is also the model HashNet was built to replace.
hashnet mining runs four distinct mining algorithms simultaneously: SHA-256, Scrypt, kHeavyHash, and Equihash, across a segmented fleet of purpose-built ASIC machines. Each algorithm group targets the most profitable coin available to it in real time.
The SHA-256 machines, Bitmain’s Antminer S21 XP Hydro units, evaluate Bitcoin against Bitcoin Cash and mine whichever is more profitable at a given moment. The Scrypt machines, Antminer L11 Hydro 6U units, target Litecoin and Dogecoin on the same basis. The Equihash machines, Antminer Z15 Pro units, switch between Zcash and Horizen. The kHeavyHash machines, Antminer KS7 units, mine Kaspa continuously, as it is the only coin on that algorithm.
The user makes none of these decisions. There is no coin to select, no profitability chart to monitor, no switching instruction to issue. HashNet’s Alpha Engine handles the entire process automatically, directing each algorithm group toward its highest-yielding target, converting all proceeds to Bitcoin, and distributing payouts at fixed intervals.
The complexity of running four algorithms across seven coins is managed entirely at the infrastructure level. What the user receives is simple: Bitcoin, on a fixed schedule, generated by a system that continuously optimises.
The structural advantage this creates over single-algorithm operations is meaningful and compounding. When one coin’s profitability declines due to a network difficulty increase, a price movement, or a block reward change, that event affects only the machines running that specific algorithm. The rest of the fleet continues operating independently, targeting at its own highest-yielding options.
No single network’s performance determines the outcome of the entire system.
“The whole point of running four algorithms is that no single market event can reach all of them at once. That’s not diversification for its own sake. It is architecture.” – Ian Issa, Founder and CEO of HashNet.
Ian built this model after identifying what he described as a structural gap in how mining operations were designed. Most operators focused on scaling within a single algorithm — deploying more machines, securing lower-cost power, and optimising hardware procurement — while leaving directional efficiency largely unchanged. The question of whether hardware was pointed at the right target, at the right time, was typically decided once at setup and rarely revisited.
HashNet’s response was to operate across multiple algorithms simultaneously. This places it among a group of leading multi-cryptocurrency mining operators, alongside Bitdeer, HIVE Digital, Canaan Inc., and Genesis Mining. Within this group, HashNet is the only operator running SHA-256, Scrypt, kHeavyHash, and Equihash together.
The result is a system that does not depend on the performance of any single network. The Alpha Engine continuously identifies the most efficient option within each algorithm, maintaining optimisation across the entire fleet.
Everything HashNet mines, across all seven coins, is automatically converted to Bitcoin before distribution. The coin selection is handled at the system level. Bitcoin is the output delivered to the user. Across four years of operation, this approach has produced over 9,400 Bitcoin for clients without a missed payout.
