🍵 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

    This picture shows up in my feed after several posts from botart (where a bot posts AI generated images).

    At first, I wasn’t sure if this photo was real or not.
