1.3 Check your hardware, BIOS and system
General Phala Hardware Requirements
A system can potentially mine Phala if it meets these general requirements:
It will also need a motherboard and BIOS which support using Intel SGX to run a Trusted Execution Environment (TEE).
Check Your CPU
Look up your computer's Processor. On Windows, you can find this in Control Panel/Settings, or right-click on the Start icon and select System. On Ubuntu, click in the upper-right corner, pick Settings, and then pick About.
Confirm the CPU supports SGX
Open Intel's website at ark.intel.com and search for your exact CPU; and confirm that CPU supports Intel Software Guard Extensions (Intel SGX).
(This image shows a CPU that supports SGX.)
Check BIOS settings
- Boot your computer into BIOS: either search the internet for the right method to boot into BIOS on your computer or look for instructions on screen immediately after a cold boot; this varies by computer model.
- Disable Secure Boot. Go to
Secure Boot, set it to
- Use UEFI Boot. Go to
Boot Mode, and make it's set to
- Enable SGX Extensions. Go to
SGX(The exact name may vary by manufacturer), set it to
If you only see the
SGX: Software Controlledoption, you will have to later run Intel's sgx-software-enable in Ubuntu. You can follow Intel's instructions to build it from source and execute it. We also provide a prebuilt binary for Ubuntu 18.04 / 20.04 that can be found here. You can download and execute it with the following commands:
1wget https://github.com/Phala-Network/sgx-tools/releases/download/0.1/sgx_enable 2chmod +x sgx_enable 3sudo ./sgx_enable
- Save and reboot.
Supported Operating Systems: Ubuntu 18.04 and 20.04
You'll need to be able to boot your computer into a supported version of Ubuntu to mine. Versions above 18.04 and 20.04 should work, but are not guaranteed.
