Hash rate - zcash not found


#1

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.


#3

Are you running the Z8?


#4

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


#5

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


#6

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


#7

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


#8

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.


#9

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.


#10

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


#11

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


#12

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

rm -rf zcash
rm -rf .zcash/testnet3


#13

Ok, thanks, I'll follow your instructions


#14

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.
