SpreadCoin (SPR) is not a new coin, but it was a mine-able only with CPU up until yesterday when an AMD GPU miner was released and today the coin also got an Nvidia GPU miner that is apparently much faster than the AMD one. The AMD OpenCL miner is available on the official SpreadCoin GitHub page (source) and there is a compiled windows binary available on the official coin website. You can get the spreadminer for Nvidia GPUs thanks to tsiv who created it (source), there is an official windows binary release for Compute 3.0 to 5.2 GPUs available on his GitHub page as well that you can download and use directly.

SpreadCoin uses SpreadX11 algorithm and does not use mining pools, you can only solo mine the coin, so you need to make sure that you have created spreadcoin.conf file with the required settings to be able to connect the miner to the wallet running on one of your computers. The config file needs to be placed in the Users\ YOURUSERNAME \AppData\Roaming\SpreadCoin folder and named spreadcoin.conf and then you need to restart the wallet, also make sure that you have downloaded the block information before trying to run a miner. You can find an example settings for the config file below if you haven’t solo mined yet and this will be the first coin that you try and don’t forget to set the username and password in the miner config to be the same and also allow any additional IP addresses or a range that will be connecting to the wallet:

rpcuser=username
rpcpassword=password
rpcallowip=127.0.0.1
rpcallowip=192.168.0.*
rpcport=41677
port=41678
gen=0
server=1

For the moment you would probably want to try out the coin if you have an Nvidia GPUs as they are performing much better in terms of hashrate than what you can get on AMD GPUs. On a stock Radeon R9 280X we managed to get just about 800 KHS using the official OpenCL miner and with the Nvidia CUDA miner on a GTX 750 Ti card we easily got over 1400 KHS, trying it out on a GTX 980 we’ve managed to squeeze close to 4500 KHS. So if you have some Nvidia GPUs, especially Maxwell-based cards you might want to mine some SpreadCoins while the difficulty is not way too high to be worth mining with one or just a few cards. Also do not forget that with solo mining luck plays an important role as well and you might get lucky and find more blocks in short time or not and wait more for little blocks, so give the miners some time.

Thanks for sharing this.
Nice to have a coin around that we can only solo mine.

I am getting around 1500 KHs with my 750 ti.

Looks like there’s a new kernel out for it for 2MH/s for AMD R9 280 however no binaries. Can someone build the binaries and post somewhere?

I’ve been running the Nvidia miner for two days now, and haven’t gotten a single payout from the miner even though I have seen it find solutions. Does it have to have the “yay” for it to count or something, or is it paying out to the donation address (like the readme suggests)?

how would the config file look like if there were 2 GTX 970 cards in the computer? Are there any extra config lines or would it work the way it is shown in the article?

For information i’ve tested gtx 960 and the hash rate is 2800 KHS
