MA difficulty algorithm #480

Closed

_xxfedexx_ wants to merge 119 commits from master into dev-v0.12

_xxfedexx_ commented

This PR changes the difficulty WINDOW=42, LAG=0, CUT=0, which is equivalent to a Moving Average (MA) with WINDOW=42 and roughly equivalent to LWMA with WINDOW=60.
The purpose is to mitigate hashrate hopping attacks.

Based on tests done using this suite: https://github.com/duggavo/difficulty-suite

_xxfedexx_ added 119 commits

util: make GMT timestamps explicit for clarity

For privacy reasons, time functions use GMT, to avoid logs leaking
timezones. It'd make more sense to use localtime for wallet output
(which are not logged by default), but that adds inconsistencies
which can also be confusing. So add a Z suffix for now to make it
clear these are not local time.

Fixed deadlock and crash when syncing with full dataset on Windows

It's not allowed to use WaitForSingleObject with _beginthread, because the thread closes its own handle before exiting.

So the wait function will either wait on an invalid handle, or on a different handle used by something else.

Or, if it starts waiting before the thread exits, the behavior is undefined according to MS: "If this handle is closed while the wait is still pending, the function's behavior is undefined."

In my test sync I observed threads getting stuck infinitely on WaitForSingleObject, and then rx_set_main_seedhash spamming new threads when RandomX seed changes again. Eventually the system ran out of resources, and monerod aborted with "Couldn't start RandomX seed thread" message.

This PR fixes it by using `_beginthreadex` instead and explicitly closing the handle when it's safe.
