[rowenta01]

Here is a very good interview on the Zcoin project!

Lots of development, and beautiful things to come ...

This project is one of the best in cryptos!

Happy reading...

Lots of crispy things ....

Thank you for your guide. I really want to try solomining with this coin. I expect I'm not wrong with this guide.

For the mining binaries, you can look at this guide https://zcoin.io/guide-on-how-to-mine-zcoin-xzc/

It's still shown " No payout address provided, switching to getwork" Anybody here helps me to I fix this . I 'm very grateful.

I think this is normal
pool mining : stratum protocol (can use getwork to but stratum is better)
solo mining : getwork protocol (there is an other one possible): should require some line in the wallet conf file if this is like others coins...

Yeah i spoke to Aizen and he said it's normal.

Thank you for your helps . I 'm trying to test solomining zcoin . it's very great if I can find a lucky block then .

Glad you got it working and good luck finding a block solo!
It will be hard with the network difficulty so let us know if you get lucky!

Zcoin wallet is broken when it comes to Getwork.
Dont waste your time using Getwork, it will show as it would hash but it will not ever find a block.
All shares willbe rejected.

Devs should fix the wallet.

We are mining with getwork on our testnet though? Will look into it. You fixed it on yours?

You are probably using GBT.
Getwork size is 128 if you did not change the size to lyra2z.
HexxCoin has it fixed, atlest when using cpuminer wallet needs the fix.
cpuminer-opt v3.6.0 works with fixed Zcoin wallet solo/Getwork.
Gpu miners not tested by myself because HexxCoin has none.

User felixbrucker has done more testing with the issue with cpuminer.

-        for(int i = 0; i < 4; i++)
-        {
-            vchData.insert(vchData.begin(), 0);
-        }
-        if (vchData.size() != 132)
+        if (vchData.size() != 128)

I have compiled Zcoin windows 64bit wallet with the fix if you need with testing..

I developped both sgminer and ccminer on the wallet using getwork (testnet)
So I can confirm the wallet is working for both miners.

This has been tested and validated. (now in view of the size of the hashrate, it will take some time before you get a block)

Wrong!
Ask joblo for help.
Or Pm me.

Im not telling that your miner would not accept current getwork code, cpuminer will not.
Wallet source is coded wrong.
Validate drops after tesing 132 size. Gpu miner allows greater.??
Also the code above not valid for cpuminer.

Why none cant see it?

then it is the cpuminer you are using which should be fixed.
Don't reverse the problem.
Fix your miner and be done with it, don't ask everybody (else) to fix their code  

ps: and don't say "wrong" you weren't be there...

just looking at your github: You forked from vtc lyra2re which had a problem in the header such that it wasn't possible to run a miner on getwork.
This problem was solved when lyra2rev2 was released. So it is mostly likely your code which is faulty

well if it just do that, then it should work... and that 132 shouldn't even concern you.
(validation is required for some coin (not zcoin) and takes place when the data are requested or uploaded to the server through getwork
(example FTC/neoscrypt)

Guys, maybe you want to meet in a chatroom, or so ?

Guys, maybe you want to meet in a chatroom, or so ?

(yeah not sure why he isn't doing this on slack)

[joblo]

1. When you changed the size test from 128 to 132 you left the byte swap at 128.
2. Hexx getwork was broken testing for 132, fixed by testing for 128.
3. The stratum code for zcoin uses 128, why not getwork?
4. 128 is the size used by most algos, stratum and getwork.

If you're so convinced the cpuminer-opt is wrong show me a miner that works.

[Ivanovski]

I see zcoin near zcash on coinmarketcap in near future!

https://github.com/djm34/sgminer-msvc2015
https://github.com/djm34/ccminer-msvc2015
enough ?

also getwork and stratum doesn't carry the same information
getwork produce a pre-arranged ascii line with the message for a miner
stratum: full header
