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.
1. Not compatible with cpuminer/ original getwork code:
-        for(int i = 0; i < 4; i++)
-        {
-            vchData.insert(vchData.begin(), 0);
-        }
2. Wrong size:
-        if (vchData.size() != 132)
+        if (vchData.size() != 128)

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

Why i have to repeat my self?
Two (2) mistakes(error in the code)
Please do not comment without testing.

I looked up vector:insert and it prepends 4 bytes to the message growing its size from 128 to 132.
Apparently this is required by zcoin but not by hexx. Those two bits of code are tighttly coupled.
If the insert is done the size is 132, if not the size is 128.

This appears to be all internal to the wallet so I don't understand why DJM34 still claims my code is broken
on zcoin. The size difference is transparent to the miner and we both work with 128 byte data.
Wrong version of cpuminer-opt maybe, getwork was broken for all algos prior to 3.6.0.

agree... hence if you submit 128bytes to the wallet it should get accepted, it will throw an error only if it is different from 128bytes...

well if your miner does not work on Zcoin (which I didn't try personnaly) hence it means it is broken (I mean at least for zcoin) and hexxcoin has been telling us for a day now, that our code is broken because you can't run your miner on it... so I am not the one saying it "per se", I just connect the dots... Cheesy

ps: actually it is hexxcoin who has been telling your code is broken and it is our fault Grin

Aizen tested yesterday again on testnet and didn't find any problem (except for your miner... sorry)

Can Aizen confirm the cpuminer-opt version used for the test? It should be 3.6.0.

I will also retest it.
Want close off possibility of an error when last time tested it.
Time after the commit and before fork, it is clear that it did not work then.

The byte reverse still looks suspicious. If the size is 132 shouldn't it reverse all 132 bytes?

Ok aizensou retested cpuminer-opt 3.6.0 on testnet and this one works...

regarding the byte reverse, I don't think it really matters as the last 4bytes are probably unused (someone would need to check the header definition and see what it really happening at that level).

Thanks for the confirmation, I feel much better now.

It appears there is a divergence between zcoin getwork and hexx getwork. It's now up to hexx to decide whether to stay
with 128 or make the complete change to 132. This update https://github.com/zcoinofficial/zcoin/commit/feb30a4dec722d5bce989e0840b9c50ed4affec5
appears to be only half of it. Your previous comments suggest it fixed an issue in Vert so it might be worth pursuing, but that's entirely up to hexx.

I glad things worked out before going too far off track.

ZCoin is seriously undervalued right now.

One of the most professional dev team in Crypto right now + Znodes/MTP coming soon.

$1,500,000 volume in the last 24 hours (17%~ of market cap), listed on BTC38.

I already invested $4,000 into Zcoin, too bad I don't have more available money at the moment.

Mark my words, we hit at least 0.05BTC before the end of the year.

I completely agree with you..

I have spotted this altcoin for over 4 months ..

Obviously it will be $ 50 before the end of the year.

It's a very professional team! Who works enormously, it's just a matter of time before people open their eyes ..

5 dollars, it is a gift for this technology, development, and supply available ..
