About VNISH

Who We Are

VNISH is a specialized ASIC mining firmware designed for Bitmain Antminers and professional mining operations. We focus on the software layer that directly controls how mining hardware behaves in production environments, including power usage, thermal management, stability, and fault recovery.

Our firmware is used by individual miners, hosting providers, and large mining farms that require predictable performance, efficient energy usage, and reliable operation at scale.

Our Focus

Mining profitability depends not only on hashrate, but on uptime, power efficiency, and hardware longevity. VNISH is built around controlled performance tuning rather than unstable peak results. Operators can adjust frequency, voltage, and power limits to match their infrastructure, electricity costs, and cooling capacity.

This approach allows mining operations to reduce energy consumption, stabilize hashrate, and extend the lifespan of ASIC hardware.

Built for Real-World Operations

Mining environments are rarely ideal. Power quality varies, temperatures fluctuate, and network issues happen. VNISH includes smart thermal logic, automatic power control, and fail-safe mechanisms to protect hardware and maintain stable operation under changing conditions.

Built-in rollback and recovery features help minimize downtime and reduce the need for manual intervention, especially in large or remote facilities.

Designed for Scale

VNISH is engineered for managing fleets of miners, not just individual devices. The firmware supports mass deployment, unified configuration, and centralized control, making it suitable for farms running hundreds or thousands of ASICs across one or multiple sites.

Security and Reliability

Security is treated as a core requirement. VNISH includes hardened access controls and system protections designed to reduce operational risk and prevent unauthorized access to mining infrastructure.

Our Experience

VNISH is backed by more than eight years of ASIC firmware development and is used on over 1.5 million devices worldwide across more than 50 countries. This real-world deployment ensures continuous improvement, broad compatibility, and reliable behavior in diverse environments.

Our Philosophy

We believe firmware is the control system of mining operations. VNISH exists to give operators control over efficiency, stability, and costs — helping them maximize long-term return on investment through predictable and reliable mining performance.
