🍵 There have been discussions about monero-pow randomX improvements for newer processor versions. One idea came to my mind: How about doing a check if a tee (trusted execution environment) is available?
Those could provide shortcuts to make CPU’s more efficient compared to that CPU’s that are currently used by ASIC-producers?
AMD:
- Platform Security Processor (PSP)
- AMD Secure Encrypted Virtualization and the
- Secure Nested Paging extension
ARM:
- TrustZone
- Realm Management Extension / Confidential Compute Architecture (CCA)
IBM:
- IBM Secure Service Container, formerly zACI, first introduced in IBM z13 generation machines (including all LinuxONE machines) in driver level 27.
- IBM Secure Execution, introduced in IBM z15 and - LinuxONE III generation machines on April 14, 2020.
Intel:
- Trusted Execution Technology
- SGX Software Guard Extensions
- “Silent Lake” (available on Atom processors)
RISC-V:
- MultiZone™ Security Trusted Execution Environment
- Keystone Customizable TEE Framework
- Penglai Scalable TEE for RISC-V
The newly announced “ASIC” is neither an ASIC nor more efficient then modern ryzen processors, making the news a nothingburger. If anything it is impressive that even with semi-custom chips they can’t outperform regular CPUs, and a testament that RandomX works as intended.
Get your privacy invading PSPs and trustzones away from here
Well, but just the proofable fact, that it’s there, could put those chips in a different position. You probably wouldn’t need to use it for anything sensitive.

Are you encouraging ASICs? How is my main pc not sensetive
