One thing I've noted though is that the 'cheating miner' code is not yet implemented?

Mr Spread would it not be wise to test/release that before it becomes necessary, if it ever does?

There is nowhere to cheat yet, existing miners can only work in solo mode. First we'll need at least some pool protocol.

Also, are there any nethash analysis/distribution tools available, possible, in the pipeline?

Due to more decentralized nature it is harder to perform such analysis for SpreadCoin. You need to monitor which node will be the first to broadcast the block. For Bitcoin you can just connect to all major pools which is not a problem as they probably are running on a good servers. Since there are no pools in SpreadCoin you will need to connect to as many nodes as you can and still the fact that some node was the first to broadcast some block doesn't mean that this block was mined by this node, it may be just distributing block which was mined by node to which you are not connected. Many computers in internet are behind NAT or don't accept incoming connections for some other reasons, the only way to be connected to such nodes is if they will connect to you which may never happen.
This doesn't mean that it is impossible but hashrate distribution analysis may be less reliable than in cryptocurrencies with pools.
No such analysis is available yet.

Mr. Spread can you please set a more informative topic in our IRC channel? With links to site, ann thread, whitepaper, etc.

New version, the only change is a new logo:
Windows wallet (32-bit)
Windows wallet (64-bit)
Linux wallet (32-bit)
Linux wallet (64-bit)
Mac OS X wallet

I've only mined 6.6 coins so far with the wallet but hey free coins are free coins right lol

Just checked my Windows wallet, mining with GPU and got a message "Not enough memory" (got 8GB) and when restarting the wallet I get message "error reading block" and the wallet doesn't start... any ideas what the problem could be and how to resolve it?

Is there something to stop botnets from mass mining this coin?

There's nothing to stop botnets, besides basic security practices, from ransacking GPU rigs all over the world either. I know people it's happened to.

I know why you're looking at this coin. I guess my question is, couldn't massive botnets be used to subvert the coin? Does this really fix the pool issue?

Massive botnets could be used to subvert anything connected to the internet. I have no idea why you would worry about botnets with this coin in particular. It's no more or less vulnerable than anything else.

And as far as I can tell, yes this does fix the pool problem. Spreadcoin looks like the only decentralised PoW cryptocurrency at this point. It doesn't do anything about massive solo farms though, but one step at a time... Grin

Good job figuring things out, but either wikipedia lied or you looked at the GT 720 which indeed seems to be compute 3.5 while the GT 720M is 2.1 according to https://developer.nvidia.com/cuda-gpus

Unfortunately some of the ccminer X11 kernels need compute 3.0 to work, therefore you're SOL.

Short version: no go.

Well, bollocks then. I'll fire up sgminer on a 270 rig.

So where exactly can spreadcoin be traded right now? and how many coins left for POW or POM left? anyone got any ideas or updates?

Trying to compile the nvidia miner, getting this error on make:

Code:

/bin/bash: nvcc: command not found
make[2]: *** [cuda_util.o] Error 127

I haven't edited the

NVCC_GENCODE = -gencode=arch=compute_50,code=\"sm_50,compute_50\"

line in Makefile.am as per the readme as I don't know what I should change it to.

I have a 720M in my laptop, can anyone help?

(I usually mine on AMD cards, never tried with anything nvidia before.)

edit: wikipedia suggested my GPU was compute 3.5, so after installing NVIDIA CUDA toolkit and changing the above line to

NVCC_GENCODE = -gencode=arch=compute_35,code=\"sm_35,compute_35\"

it is continuing to compile, hurrah!

edit2: OK, after creating a spreadcoin.conf and adding this:

Code:

rpcuser=me
rpcpassword=meme
rpcallowip=127.0.0.1
listen=1
server=1
daemon=1

I restarted the QT client and ran the miner:

Code:

./spreadminer -o http://127.0.0.1:41677 -u me -p meme
   *** Spreadminer 0.1 - a SpreadX11 miner for nVidia GPUs ***
   based on ccminer 1.2 Copyright 2014 Christian Buchner, Christian H.
   based on pooler-cpuminer 2.3.2 (c) 2010 Jeff Garzik, 2012 pooler
   SpreadX11 additions by tsiv
[2014-12-02 14:47:11] 1 miner threads started, using 'spreadx11' algorithm.

[2014-12-02 14:47:11] GPU #0: GeForce GT 720M, 3554812 khash/s

And that's all it outputs. Nvidia settings app reports GPU temp up to a steady 51C and fan is whirring but there's no further console output, is this normal?

not really, the hashrate is completely wrong.
for comparison a 980 makes about 4600 khash.
just give compute_30 a try - otherwise write a PM to the miner dev (tsiv)

Mr. Spread when will you release a wallet with new logo?

It's not only the wallet but also OP, website, twitter, cryptcointalk + contact all exchanges & services which list SpreadCoin. I will do it today.

Quote from: Mikolo on December 02, 2014, 11:06:43 AM

And do you have any plans regarding marketing and promotion of our coin?

I will contact again all major exchanges, I did it in the past but SpreadCoin was much less known at that time.
There was also a proposal to start promoting on some website called Tsu. I have no idea what is it, I didn't try it yet.
I'm good developer (I hope) but I'm not good at such things as marketing. I would be glad if anyone wants to help. In fact you (not only Mikolo) can start doing it without me, e.g. create SpreadCoin community at some social networking website or contact some media or services.
