Hash rate - zcash not found

HI, since days I’m mining, having more or less the following hash rate, without finding any zcash , what can I do? During Z8 instead I found many of them!

~/zcash$ ~/zcash/src/./zcash-cli zcbenchmark solveequihash 10
[ {
“runningtime” : 31.14366900
“runningtime” : 32.29338600
“runningtime” : 41.11758100
“runningtime” : 26.97164800
“runningtime” : 76.72111200
“runningtime” : 50.40741600
“runningtime” : 11.95169500
“runningtime” : 63.47605300
“runningtime” : 37.94357700
“runningtime” : 37.41085400

Thanks in advance for any answer

I seem to be having trouble finding testnet coins the last 2 days, while I was mining 2-5 blocks a day for the last few days. It seems someone is manipulating the timestamp and grabbing all the coins.

Are you running the Z8?

I did the up grade to z9 and I’m mining them

Are you mining with cores or threads? Cores hit more blocks for me, even though they test the same.

How you mining with “threads”? I assume by cores you mean you set genproclimit=4 or -1.

Wait for Beta to come out today. Delete the folders zcash and .zcash/testnet3 before reinstalling (instead of upgrading).

I think he means assigning cores are more efficient than assigning threads for Equihash.
Many Intel CPUs have 4 cores / 8 threads because if Intel’s hyperthreading. So setting genproclimit at 8 on a 4 Core hyperthreded CPU may in fact degrade performance instead of increasing it.


I turn off hyper threading in the bios. It halves the number of processors but I mine more blocks. Speed tests are the same either way.

Solveequihash running on 4 cores with 8 threads died. Running on one core and one thread worked like a charm (in Alpha).

When I upgraded to z9 I deleted the file .zcash/testnet3 with z8 data, is it correct?

They will soon announce Beta. Before you install Beta (“z10”) delete the zcash and .zcash/testnet3 folders.

rm -rf zcash
rm -rf .zcash/testnet3

Ok, thanks, I’ll follow your instructions

Im running beta fine now

Diff 2.73 :wink:

Hi, it works but I’m finding difficulty very strange as below :

“version” : 1000000,
“protocolversion” : 170002,
“walletversion” : 60000,
“balance” : 0.00000000,
“blocks” : 664,
“timeoffset” : 0,
“connections” : 1,
“proxy” : “”,
“difficulty” : 38.41793222,
“testnet” : true,
“keypoololdest” : 1473513315,
“keypoolsize” : 101,
“paytxfee” : 0.00000000,
“relayfee” : 0.00005000,
“errors” : “This is a pre-release test build - use at your own risk - do not use for mining or merchant applications”

is it normal? thanks in advance

It seems normal to me. If you’re comparing it to a Bitcoin difficulty, it will be much lower both because Equihash is a more computationally intensive proof-of-work than SHA-256d, and because the Zcash testnet has much less mining power at the moment. It’s expected that the difficulty will have increased significantly between @trolloniex’s post and yours, because people are just starting to mine on the beta 1 testnet.
