In the past 2 hours I've found 9 blocks, worth 14338.12 GRA, but they've all been orphaned. Net gain: 0.0 GRA
Just personal guess, if find a block wait while PoS, and, try to put into the block,
There are some time gap, and duplicated or more miners try at once,
Some time lost, some time win,
Yes, that's a normal orphan, where two or more miners find the same block almost simultaneously. That is a clear conflict where only one miner can win, and it is usually resolved quickly (not 7 confirmations later!)
In this case most of the orphans are created by a PoS block minted a little later (like 2 or 3 minutes) that wipes out the PoW mined block(s). PoS fighting PoW.
Yes, you are right,
i have experienced also, after i mined a coin, and it is listed for couple of seconds, but, it is gone from list, and, some time it is report from QT, but, even not in list,
This cases are the mined coin is invalidated by the followed (or same time) PoS
And, normal orphans are listed while running QT.
Actually, i have experienced with the other coins also.
I just though that is orphan with PoS,
Anyway, it is not affect on the mining result (all have in same situation, and relatively lower number of coins that target, but, all miner in the similar condition) but higher affect on solo than Pool, i guess,
Anyway, that is happen in QT1.3 and reduced in QT 1.4 still there even lower
Update : i guess the dev team of this coin will find a better way to handle that issue, and, will become more advanced coin ^^; while improving, grain will be growing more ^^; we can keep checking this issue together ~
