Hi everyone! As people are discussing, Quark's hybrid POW/POS code is now live. I've held off posting as we initially did some due diligence to ensure the code was working properly, and everything has checked out. I'm currently staking and have received rewards. Note that the code is rewarding retroactively - this wasn't initially intended, however it can be seen as a bonus for all of Quark's long term supporters!
As an update as well - the masternodes are currently still being debugged, but progress is being made. Implementation of the masternodes, with full governance and likely a 1% per annum masternode rewards and a small development fund to spend via the budget mechanism is what's currently planned in the next release.
