It's a pity to read such words, but I have no arguments to convince you not to give up on coin...I keep waiting and holding. I believe the team can solve all the problems.
Today my second node has been in expired mode also, because kzcashd not synced with network..
And the most sad fact of this story is the fact that the coin team are not so active in this tread and keep silence all day long...
If I were "coin starter" , I would refresh my ANN topic every min...but not once a day. Because community is one of the most important mainstay for every coin.
And I believe its not so difficult just to type some words like "people don't worry, we recognize the problem and the reasons, that is because of....we gonna fix it in x day x hours"....

anybody can fonfirm this pool is not scam ? http://kzpool.com/tbs i mining there 5 hours in 1 d3 and still no received any coins. there is Pending 78 block when i mining was over 90 so some block was confirm.. I have open my wallet but no transaction.... anybody can help ?

Still getting this from time to time.
Actually i can provide more debug info if required.
Maybe you should just wait, as i can see, this is official pool. And it should pay.

Well..I am sure that pool is okay, so high hashrate there)
But you wallet seems to be not announced in blockchain at all..so seek problem on your side, check your wallet sync, try to use other p2pool posted here at the beginning.

What is output for “ ./venv/bin/python bin/sentinel.py” now? And for test script

it looks like scam ... DEV SUPORT !!! ??

Payment are working for me on both old and new versions. So it doesn’t metter.
Problem on your side. You need to have “some dance” with this coin to make all the things work ))
Have you checked you address balance on blockchain? Is your MN wallet synced?

Today are too many troubles with theese pools - http://pool.penza.me:8279/static/ and http://mine.janche.ru:8279/static/ 

Hi gays! What's happening? In the morning there were 8 KZC in the account. It's now 0.04 KZC. Where's all gone?
