PixelPlex has modified Bitmain Antminer S19’s software to meet the client's requirements, resulting in enhanced energy efficiency, reduced costs, and increased flexibility.

Business opportunity

The client uses Bitmain’s Antminer S19 for Bitcoin mining. Yet, its firmware comes with drawbacks, functioning below optimal capacity and limiting modifications to its mode. It also has a high energy consumption.

Seeking to overcome these hurdles, the client explored various market alternatives, such as VNISH, Awesome Miner, and Brains, enabling the overclocking of Bitmain’s Antminer to boost equipment efficiency. While these options enhance mining output, they carry a downside: a 2% commission fee on mining earnings.

The client aimed for enhanced mining efficiency and reduced commission fees, entrusting us with this task based on our success with the PegaPool platform.

Project goals

  • 1

    Ensure increased efficiency for Antminer S19

  • 2

    Reduce energy consumption

  • 3

    Eliminate commission fees

Work done

  • Evaluation of solutions provided by competitors
  • Research and modification of Antminer S19’s firmware to improve energy efficiency and incorporate flexibility that was previously missing
  • Analysis of Antminer S19 to understand the nuances of the system and the possibilities for its modification

Solution

After thorough research, our team modified and customized the firmware to optimize its mining efficiency. The client received a solution that improves energy efficiency ratio and offers more flexible control over the mining strategy. The development process took three months. Rigorous testing was conducted at the client’s PegaPool farms to ensure effectiveness.

Improved energy efficiency ratio and eliminated costs

Through strategic modifications to Bitmain's Antminer, our team successfully enhanced energy efficiency without compromising the mining pools' optimal performance. Our efforts led to a significant improvement in the energy efficiency ratio, reducing it from 29.5 J/TH to 23.2 J/TH. It's important to note that a lower J/TH ratio indicates better energy efficiency, making this reduction a notable achievement in optimizing mining operations.

Furthermore, these modifications enabled the client to avoid the commission fees that third-party firmware solutions, designed to improve the Antminer’s efficiency, typically require.

Increased flexibility

The delivered firmware enables the client to devise various mining strategies tailored to their specific needs. This provides them with complete control previously unavailable with Bitmain's original solution.

Now, the mining farm administrator has the ability to adjust the mining pool’s energy efficiency parameter (J/TH) of the mining pool to enhance its profitability. For example, mining at a higher speed is feasible when electricity costs are lower. Conversely, in times of higher electricity prices, switching to a more economical mode is possible.
