Command-and-Control Risks in Miner Firmware
NTP is an essential protocol normally use for mass time synchronization where a miner periodically sends requests to an NTP server any adjusts its local time so that it is in sync with the rest of the world. Some miner firmware hard-code NTP server addresses that resolve to infrastructure hosted on the Internet that is…

Hash Rate Theft
Hash rate theft—sometimes called hash hijacking—has emerged as one of the most damaging and difficult-to-detect threats in Bitcoin mining operations. It occurs when attackers redirect part or all of a miner’s computational power to their own wallet, stealing rewards while leaving systems running and consuming energy as usual. Hash rate theft is the redirection of…

Weathering the storm
How to mitigate the impact of mass reboots Planned or unplanned power events affecting your miners can wreak havoc on your network. Even locally isolated power events can have a negative impact on your seeming healthy miners. When thousands of miners reboot, or power up, at the same time, the impact on L2 switches mac address…

DHCP and DNS Best Practices for Large Scale Bitcoin Mining Environments
Manually assigning IP addresses to thousands of miners quickly becomes operationally unmanageable. Implementing Dynamic Host Configuration Protocol (DHCP) provides an automated, scalable solution for deploying and maintaining large fleets of mining devices. When miners are configured for DHCP (the default in most firmware), each device broadcasts its unique MAC address at Layer 2 and requests an…

Wekos Remote Operations NOC
Bitcoin mining operations are mission-critical, power-intensive, and network-dependent enterprises that demand unwavering uptime and precise control. As these facilities scale across multiple geographies—from hydro sites in the Pacific Northwest to solar-powered farms in the Southwest—the complexity of managing networks, power, and operations grows exponentially. Wekos’ Remote Network Operations Center (NOC) delivers a fully managed, 24×7×365 monitoring…

Starlink: The perfect solution for remote mining operations?
Starlink’s low-Earth-orbit (LEO) satellite network has revolutionized internet access for off-grid and rural areas. Its promise of broadband-class connectivity almost anywhere on Earth has attracted interest from industries that depend on reliable communications in remote regions — including Bitcoin mining. Yet while Starlink enables miners to establish operations far from traditional fiber routes, its current architecture presents…
