Compute Horde: Revolutionizing Decentralized Computing in the Bittensor Network

Understanding Compute Horde

Compute Horde, also known as subnet 12 in the Bittensor ecosystem, is not a traditional service subnet. Instead, it functions as an infrastructure layer, offering computing resources that can be utilized to build and run various applications. Unlike subnets that provide specific services (e.g., subnet 17 for 3D model generation), Compute Horde focuses on providing the underlying computational power necessary for diverse tasks.

Key Components of the Compute Horde Ecosystem:

1. Validators: Responsible for verifying the work of miners and distributing tasks.
2. Miners: Provide the actual computing resources (GPUs) to the network.
3. Facilitators: Act as intermediaries between users and the subnet, handling job submissions and results retrieval.
4. Users: Submit computing jobs to be processed on the network.

The Compute Horde Architecture

The subnet's architecture is designed to ensure efficiency, security, and scalability:

1. User Interaction: Users interact with facilitators to submit jobs and retrieve results. This separation allows for a more user-friendly interface while maintaining the security of the underlying network.
2. Facilitator Role: Facilitators manage job submissions, handle data storage, and communicate with validators. They serve as a crucial bridge between the user-facing side and the core network operations.
3. Validator Functions: Validators select miners, distribute tasks, and verify work. They play a critical role in maintaining the integrity of the network and ensuring fair distribution of resources.
4. Miner Operations: Miners execute jobs using Docker containers, ensuring isolation and security. This containerization approach allows for flexible and secure execution of diverse workloads.

Job Execution Process:

1. Users submit jobs to facilitators through a user-friendly interface.
2. Facilitators communicate with validators, relaying job requirements and specifications.
3. Validators select appropriate miners based on availability, capability, and fairness algorithms.
4. Miners download necessary Docker containers and input data from secure storage locations.
5. Jobs are executed on miners' hardware, leveraging the power of distributed GPUs.
6. Results are returned through the chain: miner > validator > facilitator > user, ensuring data integrity and security throughout the process.

Verification and Security Measures

One of the most critical aspects of Compute Horde is its robust verification system, designed to ensure the integrity of computations and prevent fraudulent behavior:

1. Hashcat Challenges: Validators regularly send hashcat challenges to miners to verify their GPU capabilities. These challenges serve as a benchmark for GPU performance and help detect any discrepancies in reported vs. actual hardware capabilities.
2. Receipt System: Miners provide signed receipts for completed jobs, which are stored and can be audited by validators. This creates a transparent and verifiable record of work performed on the network.
3. Load Balancing: Validators are required to distribute work evenly among miners to prevent collusion. This mechanism ensures fair participation and reduces the risk of centralization within the network.
4. Cross-Subnet Verification: Partnerships with other subnets (e.g., subnet 17) provide additional verification mechanisms. This inter-subnet collaboration enhances the overall security and reliability of the Bittensor ecosystem.
5. Dynamic Verification Strategies: The network is designed to adapt its verification methods continuously, making it increasingly difficult for malicious actors to game the system.

Challenges and Solutions:

1. Deterministic vs. Non-deterministic Jobs: Addressing the verification of non-deterministic computations poses a significant challenge. The network is exploring various approaches, including statistical sampling and reputation systems, to handle these cases effectively.
2. Cheating Prevention: Implementing strategies to discourage and detect fraudulent behavior by miners is an ongoing process. This includes advanced monitoring techniques, economic incentives, and potential slashing mechanisms for proven bad actors.
3. Resource Allocation: Balancing immediate availability with cost-effectiveness in GPU provisioning requires careful optimization. The network aims to provide both on-demand resources for time-sensitive tasks and more cost-effective options for less urgent computations.
4. Scalability: As the network grows, ensuring efficient task distribution and result verification across a large number of nodes becomes increasingly complex. Ongoing research focuses on optimizing these processes for large-scale operations.

GPU Utilization and Network Growth

Compute Horde has seen impressive growth in GPU resources, reflecting the increasing demand for decentralized computing power:

• Current GPU count: Approximately 574 (as of the latest update)
• Daily growth: 50-70 GPUs added per day
• Dominant GPU model: NVIDIA A6000, chosen for its optimal cost-performance ratio

The subnet incentivizes miners to provide high-performance GPUs, leading to a competitive environment where more efficient hardware pushes out less cost-effective solutions. This natural selection process ensures that the network continually evolves to offer cutting-edge performance.

Future plans include introducing new hardware classes to support models requiring larger VRAM (e.g., 80GB cards for large language models), further expanding the network's capabilities and use cases.

Monetization and Market Dynamics

Compute Horde is positioning itself as a cost-effective alternative to traditional cloud computing services, leveraging the unique advantages of blockchain technology:

1. Free Tier: Currently, users can run jobs for free, subject to queue times and available resources. This strategy aims to attract early adopters and demonstrate the network's capabilities.
2. Future Pricing Model: Plans to introduce a pricing system that remains competitive with traditional cloud providers while leveraging blockchain subsidies. This model aims to offer significant cost savings to users while ensuring sustainable rewards for miners and validators.
3. Validator Earnings: Validators can monetize their allocated resources, potentially sharing earnings with facilitators. This creates a multi-tiered economic model that incentivizes participation at various levels of the network.
4. Market-Driven Scaling: The number of GPUs and their utilization is expected to fluctuate based on Tao token price and subnet weights within the Bittensor network. This dynamic scaling ensures that the network can adapt to changing market conditions and demand.
5. Flexible Resource Allocation: The network is designed to support both always-on resources for immediate availability and on-demand resources for cost-effective scaling during peak times.
