One-GPU-Per-PC Policy - Design Rationale
🧠 Overview
The One-GPU-Per-PC policy is a deliberate architectural decision at the core of the HashCloud (HCLD) mining protocol. This rule limits each miner instance to one active GPU per installation. While it might seem restrictive from a traditional mining perspective, it serves as a crucial foundation for ensuring network fairness, system stability, and broad decentralization. By standardizing miner configuration, HashCloud prevents excessive consolidation of compute power within a single operator or machine, ensuring that rewards are distributed equitably based on genuine network participation. Users who wish to deploy multiple GPUs are still fully supported they can simply run multiple installations on different systems, each operating as an independent node under the same wallet or account. This preserves scalability while maintaining decentralization and verifiability at the protocol level.
⚙️ Technical Design Rationale
Simplified GPU Management
Supporting multiple GPUs per instance introduces complex engineering challenges, such as driver conflicts, VRAM contention, and synchronization delays between GPU threads. HashCloud minimizes these technical burdens by enforcing a one-GPU-per-instance rule, resulting in a lightweight, highly stable miner that functions consistently across a wide variety of devices. This design choice enables the miner to run efficiently on everything from entry-level gaming rigs to enterprise-grade servers without specialized configuration.
Cross-Platform Consistency
HashCloud is built to support diverse hardware ecosystems including NVIDIA, AMD, and Intel GPUs across different operating systems. Multi-GPU environments often behave inconsistently due to driver or platform differences, leading to performance variability and frequent bugs. By focusing on a single-GPU architecture, HashCloud ensures that each miner behaves predictably, simplifying updates, performance tuning, and network-wide compatibility. This uniform behavior makes it easier for developers to roll out optimizations and for users to maintain their systems without technical expertise.
Simplified Troubleshooting and Maintenance
In multi-GPU rigs, diagnosing failures can become an operational nightmare. An issue in one GPU may cascade across others, causing miner crashes, driver resets, or system instability. HashCloud’s single-GPU model isolates potential failures if one machine fails, only that individual node is affected. This reduces downtime, simplifies error tracking, and allows for rapid issue resolution. The result is a network composed of many independently stable nodes, each contributing reliably to the overall compute fabric.
💰 Fairness and Decentralization
Equal Opportunity Mining
HashCloud’s mining model is designed to empower the individual, not the industrial miner. By enforcing a one-GPU-per-PC rule, large mining farms cannot dominate rewards through hardware stacking. Instead, compute performance per node becomes the core measure of contribution. This fosters a fair, decentralized ecosystem where home miners, developers, and small operators have equal opportunity to participate in token distribution.
Balanced Network Contribution
Every node in the HashCloud network represents a unique, verifiable contributor. The single-GPU policy ensures balanced compute distribution, preventing situations where massive GPU clusters distort network statistics or accumulate disproportionate rewards. Each device contributes predictably, allowing HCLD emissions to follow a mathematically fair curve that reflects actual compute power rather than centralized hardware advantage.
Lower Entry Barriers
This policy also supports HashCloud’s mission of mass adoption. Anyone with a standard consumer-grade GPU can begin mining without needing specialized or expensive hardware. This inclusivity encourages community participation from a global audience spanning hobbyists, students, developers, and AI enthusiasts making decentralization a natural outcome of accessibility rather than exclusivity.
🔐 Security and Anti-Cheating Measures
Hardware-Based Device Identification
To uphold fairness and prevent manipulation, each miner instance generates a unique device ID derived from immutable hardware signatures such as the GPU’s UUID, system BIOS serial, and MAC address. This cryptographic fingerprint ensures that no two miners can operate on the same machine, effectively preventing multi-instance spoofing, virtual GPU emulation, or synthetic workload attacks.
Exploitation Prevention
HashCloud’s verification layer is designed to identify and block attempts at multi-GPU spoofing, container-based mining duplication, or virtualized farm simulations. Because every miner is cryptographically bound to its hardware identity, even advanced users cannot create artificial GPU replicas to gain an advantage. This protection layer preserves integrity and ensures that every token earned corresponds to real, physical computation.
Controlled Network Growth
The one-GPU-per-PC approach gives HashCloud’s backend infrastructure enhanced visibility into the network’s structure. Each registered node can be validated, monitored, and benchmarked independently, allowing the protocol to track global compute capacity accurately. This control mechanism enables secure network scaling, adaptive difficulty adjustment, and transparent miner registration all of which are essential for long-term sustainability.
🚀 Future Compatibility and Scalability
Despite its limitations, the One-GPU-Per-PC policy does not restrict scalability. It encourages it through distributed deployment. Users who wish to scale their mining operation can run multiple independent nodes on different machines, each connected to the same wallet. This mirrors distributed computing models used in major cloud systems, ensuring that HashCloud grows through horizontal scalability (more devices) rather than vertical monopolization (more GPUs per machine). This model also future-proofs the protocol for edge computing, mobile GPUs, and low-power devices such as portable consoles or mini PCs. HashCloud’s modular miner architecture allows these devices to contribute meaningful computation without complex configuration, supporting a diverse and adaptive global compute network.

By combining simplicity with security, HashCloud ensures that every participant regardless of hardware scale has equal opportunity to contribute, earn, and strengthen the network. This approach keeps the system stable, sustainable, and fundamentally aligned with its mission: to build a decentralized compute cloud owned and powered by the people.
