Issues Here, I have done the update and staking has increased from 0.00000001 to 0.00000002
though ever new mine results 16 so far in total are generated but not accepted
there has been no change to the staking code yet, it updates on block 55k.
Do you mean you have had a lot of orphan blocks?
Yes all orphan blocks 16 in a row 17 block has mined 18th block is generated but not accepted/orphan
17th most recent block paid 0.0002 so this is huge compared to all past blocks of only 0.00000001 that my wallet has mined
18 Block back to 0.00000001 and has generated but not accepted/orphaned
It's not a big deal, it happens with all POS coins. Someone else got that particular stake reward before you, but your inputs will increase their coin age and eventually stake all the same.
As for the low stake reward, if you have the latest wallet the accurate intended POS rate of 4% will kick in at block 55k in a few days.
