Spreadcoin Mining Guide

Step 1: Make sure you have downloaded the Spreadcoin client and the miner that suits your graphics card. (AMD or Nvidia) You can find all of these download links below.

Client Download (version 0.9.15.2, released December 24, 2014)

Mac OS X wallet

Source code

AMD GPU Miner
Windows binary: http://spreadcoin.net/files/Spread-GPU-miner.7z
Source code: https://github.com/spreadcoin-project/spreadcoinx11-sgminer

You need latest drivers to use this miner. Known to work on 14.9 installed from file named amd-catalyst-14-9-win7-win8.1-64bit-dd-ccc-whql.exe from http://support.amd.com/en-us/download/desktop?os=Windows%207%20-%2064

Nvidia GPU Miner

Win32 binary: https://github.com/tsiv/spreadminer/releases
Source: https://github.com/tsiv/spreadminer


Step 2: You only need to do this step if you have an encrypted wallet

So first off, head to %appdata%/Spreadcoin. You can find it by opening windows explorer and typing it into the bar at the top:


Press Enter. Now you will be taken to a folder named Spreadcoin with a few files in it.
In the next step I'm going to assume you don't have a spreadcoin.conf file in this folder.

Step 3: Now you need to right click and create a new text document as shown below.



Leave it named as "New Text Document". Now open the document and paste this text into it:

Code:

miningprivkey= <we will fill this section out later>

Now we can save the file. But we need to name it spreadcoin.conf so click file > save as
Now make sure to change "Save as type" from "Text Documents (*.txt)" to "All Files (*.*)"
Then type the file name as "spreadcoin.conf" and click save.
Now you should see a new file called "spreadcoin.conf" in the Spreadcoin directory. If you can't see it there then you might need to refresh the page but if you can see it there then you can minimize the file explorer window as we will come back to it later.


Step 3: Now you can extract the client that you downloaded earlier from the zip file and run it. (You may need to install 7-zip) (if you already had the latest client downloaded and running then you can skip this step)


Step 4: Follow this step ONLY if you have an encrypted wallet.

Create a new address that you would like your miner to mine to and copy it to the clipboard. This address will be slightly insecure as you will need to expose it to your miner.

In the Spreadcoin client in the toolbar at the top click Tools > Debug Console

Then type "walletpassphrase <your wallet password> 120".
Now type "dumpprivkey <wallet address>" where the wallet address is the address you copied to your clipboard before.

The wallet will reply with the corresponding private key. You will need to copy this key and then open up the spreadcoin.conf file you minimized before.

Type "miningprivkey=<paste the key you copied out of the spreadcoin client>"

You can now save and close the spreadcoin.conf file.
Once you have done that you will need to restart the client.


Step 5: Now that the client is up and running you can extract your miner from it's zip file. Navigate to the folder you extracted it from and find the file named "start.bat". Depending on your computer the file may not have ".bat" on the end. Then you can right click > edit.

Now you might need to erase everything except the word "sgminer" (it worked for me) and then you can proceed to add custom modifications to the default values. Here is a list:

My start.bat file is very simple and looks like this:

Code:

sgminer -I 20

-I 20 means "Set the intensity to 20". You can change 20 to be any number from 8 - 31. Higher is better but your graphics card may not be able to handle the load if your intensity is very high.


For Nvidia users, the included example.bat should work right off the bat so all you need to do is run it.

Now you can run start.bat and it'll (hopefully) look something like this:

airball in still waiting for you dump for that electric bill. 

No hurry,I will,just wait~ 
I've dumped 13K XMR today to pay part of my electric bill.

Damn, part of your electric bill. How much is it? 13k XMR is like $6,200.

about $8000 last month,plus 650$ house rent 

[binary_tree]

In the near future,you guys will get 40K-60K of my SPR,I promise.

Interested in selling 1 btc privately now?

I don't think he'll sell you spreads worth ONLY 1 btc in private.

He turned down the guy wanting 25 btc worth a few days back.
Just trying to be more realistic/hopeful lol
No worries either way.
Any real sell at all and my orders filled.

I didn't turn  him down.I just don't want to sell cheap and sell big amount to one person.

I'll donate 5 SPR to 40 different people in this thread who have 25+ posts if airball posts proof that he has more than 50,000 SPR.

I don't think he does.

If you're planning to sell size, advertising as much isn't exactly the smartest thing to do.  I think he is hoping to shake out weak hands.

I can prove it very easily with solid evidence I have 50K+ spr.
40*5=200
how about let's have a bet?

I'll give you 3 addresses whose total balance is 60K+ spr.
of course you can check those public addresses from the block explorer.
To prove I own those wallets,I'll send 200/3=66.66 spr from each of them into the same address.
If I can do this above,you pay me 200 spr.
if not,I pay you 200spr.
fair enough?
want to bet or not?

All I want is my CPU to find a block and Ill feel accomplished.
But Ill take a quick 5 too I suppose lol

how about 6.6 spr (the initial block reward after #1300) to 300 people who joins this community now and in the future ??
If I can't prove it,to make things simple,I donate 5K to Spreadcoin community.
Whoever loses or win,in any case,it is good for this community.

correct, when your wallet( server) and miner(client) are in the same mining rig.
To mine with many other miners on different rigs,you need to make some changes of the spreadcoin.conf and start.bat.

Yeah. Its correct for what hes using, obviously, because he has it working. Following it, if you have that setup is foolproof with the exception of tweaking specs for your GPU.
Im having trouble configuring my Nvidia cards still. Maybe someone can help.

What is the difference in X11 vs Spreadx11 or whatever its called.

I think I could use my Cudaminer setup thats already functional otherwise if I knew what the technical differences were.

The guide 8space submitted is nice just a little confusing explaining the .config but the dev says its already there.

To clarify the explanation of creating the .config is easy to understand and the dev having it already implemented is easy to understand
but the communication between the two; if you need to add it (.config) to mine despite it being integrated, is what is foggy.
