Last night I restarted mining this coin.
Are the coins I've mined over the past 12 hours still valid?
They should be ...
Unless orphaned (which you can check by the Block Explorer here -
https://chainz.cryptoid.info/ozc/). Where did you mine? On Amethyst (MPOS system) or Citrine (Yiimp)?
We are seeing the majority of blocks going to one miner mainly. Some blocks going to others, but mainly one miner is getting the majority of blocks as he has the largest hashrate.
Over the coming days, the MPOS Mine will be updated with the latest code (after it is committed to Git) and test also. If all is well, we should have an easier time to upgrade to the maintenance release, so that Cryptopia can also upgrade (and all others who have OZC on their servers).
