Why Do We Need to Update the Firmware?

We are all aware that science and technology, including firmware, are constantly being improved through iteration. With the aid of a firmware update, the mining device can have some features added and can become more effective.

These firmware updates could result in mining operations using less electricity.

Some firmware updates may also increase the processing power of the miner. The same machine can be given more processing power by updating the firmware. The mining profits of miners can increase thanks to this firmware.

Additionally, firmware is available to enhance high-temperature protection, restart, and other procedures. for miners. The dependability and stability of the miner can be improved by using such firmware.

The firmware is effective, but not all firmware updates can be completed quickly. As soon as miners realized a specific firmware could significantly increase computing power, they downloaded and updated the machine’s firmware regardless of the source. As a result, the device operates erratically and may even result in mining device contamination and computing power theft. The official firmware that was provided with the mining machine should always be used, according to this.

What is the Security Firmware?

To safeguard the interests of ANTMINER users, the security firmware was created. Every feature from the previous version is present in the firmware. By disabling SSH access, you can more effectively stop unauthorized attempts to hack miners, block the spread of viruses, and protect your mining from remote attacks.

How to Distinguish the Security Firmware?

Know which one is the security firmware via the following ways:

  • The file name of the security firmware ends with a sig.
  • After the security firmware is reloaded, SSH access will be turned off.

What Are the Functions of the Security Firmware?

The primary distinction between security firmware and regular firmware is that SSH connection is not possible with security firmware because firmware signatures are present and SSH access is disabled.
