zcash testnet mining ERROR

Linux 16.04 running z-nomp and testnet zcash deamon.

from .zcash/testnet3/debug.log:

...
2018-06-06 18:00:46 ERROR: ContextualCheckTransaction: overwinter is active
2018-06-06 18:00:46 ERROR: ProcessNewBlock: AcceptBlock FAILED
2018-06-06 18:00:46 ERROR: ReadBlockFromDisk: OpenBlockFile failed for CBlockDiskPos(nFile=-1, nPos=0)
... and repeat

mining program tells the miner connects via stratum+tcp ok, and getting job ok

this is frontend: http://45.76.158.225:8080/workers/tmBURopfSysgy2aSXMLQ15Ck47wipfVq5SH

Everytime reproduce

Expected behaviour

I should be able to mine some blocks (given network only ~20Sols/s, One GPU is output 300+Sols/s)

Actual behaviour + errors

What's your config in coins folder

c2h2 commented 6 years ago

Thanks for the reply, default coins folder, untouched, do I need to change anything?

Tomas-M commented 5 years ago

I am struggling with the same problem. Did you solve it anyhow?

c2h2 commented 5 years ago

with my custom patch and v1.1.0 zcash testnet. it‘s working！and v4 transaction is also implemented by me. Thanks to @hellcatz!, will donate some coins to him.

Hi, are you able to mine block on the main net using your workaround? @c2h2
