I'm getting the same error with the wallet encrypted. The only place I could find to unlock the wallet was in the Vanity Gen tab. After doing that I'm still getting the same error... :(

but now I don't know how to unlock it? Would it have been locked after a fresh install? How do I unlock it now it's definitely locked?

Well, once a wallet is in encrypted mode it isn't possible to turn it back to unencrypted (no password use).
The only thing you can do now is use your password to temporarily unlock it.

So, did the error -4 go away?

EDIT: if you want to go back to a fresh "no-password" wallet you would need to dump all your privkeys and import them into your fresh wallet.

Hi,

Thanks for your reply. I didn't think my wallet was encrypted as it was a fresh install. In trying to unlock it a few minutes ago I went to Settings > Encrypt Wallet and entered a password, but now I don't know how to unlock it? Would it have been locked after a fresh install? How do I unlock it now it's definitely locked?

You can't import into an encrypted wallet, it needs to be unlocked.

Hi,

I'm getting "Error adding key to wallet (code -4)" when I importprivkey?

Thanks,

You need spreadminer and not ccminer.

That could be it.
If a person uses ccminer (X11 version) with the spreadcoin wallet, it wouldn't even throw an error and tell you about it.
Those tools are not very sophisticated.
Also, it isn't like the spreadcoin wallet is broadcasting to the mining tool what Hash Algo it needs to run.
Neither ccminer nor wallet will complain when the Hash Algos do not match.

Now that you mention it, crypticj states that he makes 12.5 MHashes with a GTX 1070, which sounds a little high for this GPU if you ask me.
This does sound like he was mining Dash or something.
With Spreadminer (the sp_ version) and GTX 1070 he would probably only make around 9 MHashes.

EDIT: Yep, I remember a conversation I had with pokeytex:

Sweet - I use all 1070's.  [...]

So how many hashes does a 1070 do [...]?
[...]

...I have SP's miner as a tool.  It gets 8500 - 8900 mhs/sec.  I have the mem clock down to -512 and the core clock at +125.

So yeah, that's probably it: wrong miner.

@crypticj: Spreadcoin uses SpreadX11 and not X11, so you will have to use the spreadcoin-version of the ccminer, which is called spreadminer.

Please when you give Heads and Tails example thats Highschool level statistics stuff, just for credential purposes I am a Data scientist for a large fortune 500 I have masters in Biochemical engineering with minor statistical analysis [not bragging ] just giving you some context to help you understand that I know what I am speaking of when it comes to statistics. FYI!!!

Okok, I believe you, lol.
But keep in mind that with the randomness of cryptographical hashfunctions (chasing solutions based on fluctuating parameters like difficulty etc) we introduce additional uncertainties (net hashrate fluctuates, block spacing fluctuates (sometimes we make 1500 sometimes 1350 blocks a day, etc..) that make the statistical calculation of chance down to 2 decimal places (like you just did) rather impossible. But I see, you just did a quick estimation anyway, but I'm just saying.


(net Hashrate varies widely over the span of just a few hours)

But yes, in general you are right: You "should have" found some blocks.

So, I can't say why you didn't find a block within the time and with the hashrate that you stated,
but I would guess that it could be that...

a) ... you didn't really check for 24 hours, but rather just for "a workday" which should be shorter
b) ... your hashrate fluctuates also (maybe your GPU scales power down after certain degrees are reached, or something)
c) ... something is wrong with your setup and you don't actually contribute your hashrate to the SPR network

It probably has something to do with c)

Please keep us updated.

when you have 1/200 chance of finding the next block and over 1500 independent instance you don't find a single block. statistically it gets harder and harder...

I'm sorry, but that's exactly NOT how randomness works.

Let's look at a simple example so you get the gist of it: let's look at the example of throwing a coin multiple times.
I win when TAILS comes up, I win nothing when HEAD comes up.

Suppose I throw a coin 100 times in a row, and it always comes up HEAD. 100 times.
Wow, that's very unlucky, isn't it?
How big do you think the chances are that TAILS comes up when I throw for the 101th time?

After all, TAILS hasn't come up for 100 throws, so now there must be a very large "pressure" for TAILS to finally come up, right?

Answer:

Nope, the chance for HEAD or TAILS to show up in the next coin toss is still 50%, as it always is, with every coin toss you make.

Your feelings or "urgency" don't matter. At all!

Just because you had the insanely improbable encounter of tossing HEADS a 100 times in a row, doesn't mean that now there is some sort of INCREASED STATISTICAL chance that the 101th throw has to be TAILS.

Nope, chances remain the same: 50%.

Every new toss (or block) has to be looked at separately, your previous success (or failure) does not influence the chance for finding the next block IN ANY WAY, SHAPE OR FORM.

Basically the lesson to take away from this example is:

Randomness doesn't owe you shit, it only laughs at your efforts, lol. ;D ;D

Please re read my response, I understand randomness and i also understand independent instances, what you are referring to is independent instance. Each block is independent of each other for my miner to find it.

What you are failing to grasp to comprehend is that over normal distribution curve when an instance goes out of 3 Standard deviation we refer to that as black swan event. The probability of not finding 1 block out of 1500 independent instance with a probability of 200 is 0.58% it is still possible anything is possible but with binomial statistical distribution as the number of blocks increases and my probability stays the same [i understand each instance is independent] there is something that is telling me that for me as  a miner it is not working.
