🍵 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?

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
