"Yes superb, nice to have a 3D artist like you in the DRK comunity!
Keep the nice work."

just fun to do that. i have no other skills

It's one of my dream to be able to make something like this.
My fisrt and last try was with my amiga 2000 on Sculpt Animate 4D.
I made an animation of a transparent sphere bouncing on two mirror... more than one week of calculation and rendering for a 32 frames animation.
After this I stop, try vaguely 3dsMax but was already lost....

I have no artistic talent at all but I like Blender, you can knock stuff up pretty quick once you've gone through a few youtube tutorials. I've used it to model some stuff that I print out on a mate's 3d printer. Smiley

Or longer, since it appears they are focusing on smoothing out Darksend for this next version. I didn't realize he was waiting for instant transactions.

I don't think Mr Spread is necessarily waiting for the Darkcoin team to implement InstantX before he does it himself...

I never said that and there is no way of knowing that

Exactly.

Anyways - testnet nodes? I can't sync.
are you going to develop a faster GPU miner ?  Huh

I plan on looking into it.

Don't hold your breath, he's probably just going to try and sell it to the highest bidder.  Cheesy

Which is fair enough, it's his work, but it isn't going to help the wider community until the wider community has it, to level the playing field again. Until then it's just going to make Spreaders poorer.

Alex, people will not invest in other than €. They even do not recognice that gold and silver could save their existance in environmet like we have in Greece
And sorry, after all the bad experiance i made in cryptoland over the last 14 months i rather would invest in cigaretts and alcohol than in crypto. In cryptoland you cant trust anybody.
After mtgox we had mintgox and now again with bitstamp.
I lost the last bit confidence in crypto.
In the end i lost 5k€ and the last thing i have is one masternode. In terms of fiatvalue i am sure this will also go to zero.

You don't have to trust anyone, that's the whole point of a cryptocurrency, but people trust exchanges with their money, every single one of which is obviously on the take, and thus get burned due to exchange dishonesty and/or exchange incompetence 

You're right though, neither the Greeks nor anyone else en masse are going to spend their dwindling supply of comedy paper on BTC or DRK when cigarettes and other tangible commodities are a more profitable and certainly less volatile investment.  Cheesy

Cryptocurrencies are a luxury item, useful in a prospering economy, not so much when you're struggling to feed your kids and stop the bank repossessing your home.

That's an odd error.... Seems like it could be related to your catalyst install. Two of the scripts check system version using the following command:

$(lsb_release -sc)

It's used to set an additional repository and to build the deb install package for catalyst 14.9. Can you run that command and tell me what it returns?

It returns:
Code:
qiana

... which means nothing to me...  Huh Undecided

Hello All,

I'm happy to report that an automated script is now available for Linux users to get started with!

This package can take a bare installation of XUbuntu/Ubuntu and prep it for Spreadcoin mining. It can also be used to upgrade an existing rig for Spreadcoin mining. It is split into 5 different scripts that are triggered individually by the end-user followed by system restarts. It contains checks along the way to see whether or not an operation needs to happen (specifically, it checks if Catalyst drivers are already installed in step 2).

  • sgminer1.in - installs common dependencies and other updates
  • sgminer2.in - installs Catalyst driver (14.9)
  • sgminer3.in - installs AMD APP SDK 2.9
  • sgminer4.in - compiles SGMiner (spreadcoindx11-sgminer)
  • sgminer5.in - creates batch file for mining

The daemon is quite easy to configure - just copy & paste the following into a terminal window:

Code:
mkdir ~/spreadcoin64
cd ~/spreadcoin64
wget http://spreadcoin.net/files/spreadcoin64.tar.xz
tar -xvf spreadcoin64.tar.xz
mkdir ~/.spreadcoin
cat >  ~/.spreadcoin/spreadcoin.conf << EOF
server=1
rpcallowip=*.*.*.*
rpcuser=user
rpcpassword=pass
EOF
cd /usr/bin
sudo ln -s ~/spreadcoin64/spreadcoind .
cd ~/
spreadcoind

Be sure to read the whole Readme at https://github.com/snogcel/sgminer-install-scripts. I recommend installing the daemon between steps 4 and 5, then grabbing a sandwich / beer and hanging out for 15 minutes before proceeding so that the blockchain can sync ;-)

Wow, great work! I shall test it later today. Smiley

OK got around to testing this on a fresh Mint 17 install.

1. ./INSTALL seems to call the arch scripts or something, I got a load of pacman not present errors.
2. So I ran each sgminer#.in script separately, #1 through #3 deleted all the sgminer scripts so I had to git clone them again each time.
3. Having successfully run them all, started and synced the wallet with the correct stuff in the .conf file, ./spreadgpu (and calling it directly via ./sgminer blah blah) gave me llvm errors:





... I think that any attempt at 1-click in-wallet GPU mining is going to result in never-ending misery, there's just too much to go wrong. Grin
908  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][SPR] SpreadCoin | True Decentralization (No Pools) on: January 06, 2015, 04:13:51 PM
I'll put a 300 SPR bounty on a miners hash chart.

Here is 2 miners chart: http://104.36.83.126/spreadcoin/
  • network hashrate
  • top miners pie chart (>1000 mined coins)

Nice work! Smiley

@georgem:

Masternodes are what give Darkcoin it's utility, and therefore value. I'm all for keeping things simple, but you need a certain amount of infrastructure to get anything useful done.  

About messaging in wallet - Masternodes would make this pretty simple, but it's pretty simple anyway. I wrote a little encrypted p2p chat bolt-on for my Darkcoin Simple Wallet that used one of my Masternodes as a key store (address book basically) - it was pretty straightforward. I never took it too far though because extremely simple was all it had to be, send a short txt message to a given address. I didn't and don't want a full blown IRC/jabber/skype/etc. client bloating up my wallet and bringing untold vulnerabilities to my ecash.

There are dozens of coins with in-wallet messaging and a hundred ways of doing it, Mr Spread could probably have it integrated in a day or two... but I hope he will keep Masternodes the priority. They really are an excellent technical and economic innovation, the n-of-m structure avoids centralisation of any service provision and makes them extremely attack resilient.

Anyway, very glad to have you here chucking ideas about!  Smiley




edit: How about we drop the 'coin' bit, just Spread?

911  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][SPR] SpreadCoin | True Decentralization (No Pools) on: January 06, 2015, 06:38:46 AM
Found 2 more blocks today, so I've got 4 in 72 hours of mining. 1 per 18 hours. 950 kh/s avg hash speed here.

Trying hard to find a rig-renting website which does solo mining but it doesn't seem to exist so perhaps I should just buy more SPR instead.
JL

I think the fact that you basically have to trust the rig owner with your privkey and your coins makes renting mega-rigs a non starter, even if you can find someone right now prepared to set up the spreadX11 algo for you.

Couldn't he fork to DGW to lessen the chances of that happening? It seems to have been proven resilient.

DGW just readjusts block payments based on network hashrate.

I don't think it can stop 51% attacks

Not quite thought through thought: Masternodes need to run for a day or two before qualifying for payment, maybe the same principle could be applied to miners - you need to mine for 1440 blocks (1 day) before you qualify to receive any block reward?

Thus, if someone jumped in with ~50% of the total hashrate, at the very least it would cost them much more, and we'd have 24hrs notice that something was up.

Using the 1day idea for mining is brill. I like how we could see the hashrate jump before it becomes a threat.

Would stopping rewards for 24 hours stop a 51% attack tho? I mean, the hashrate is still in the network, just not getting paid?

I think you'd need to somehow just plain reject anything from a miner without the required 'uptime.'

This might be a problem for people who have unstable mining rigs... Tongue

Honest long term miners shouldn't mind the wait, but it might deter opportunistic attackers...?  

In fact, what about a 'DGW curve' for block rewards - 1440 blocks no reward, next two days 25% then 50%, next day 75%, after 4 days you get the full block's worth. (Yes I know that's a line not a curve, you get the idea.)

This would give SPR a huge boost in blockchain security.
916  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][SPR] SpreadCoin | True Decentralization (No Pools) on: January 05, 2015, 03:35:17 PM
In the context of 51% attacks, mining pools have no incentive to disrupt whereas if there was a single person with access to the hardware and the motive, would Spreadcoin be vulnerable?

Mining pools are one single person with access to the hardware. In fact they are worse, as if the pool server is located in a datacentre dog knows how many people have access to it beyond the pool operator.
917  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][SPR] SpreadCoin | True Decentralization (No Pools) on: January 04, 2015, 03:20:17 PM
I also want to know how the the net hashrate are calculated.

Exactly the same way any BTC derived wallet does so. (I imagine, and don't ask me for the exact mechanics of that.  Cheesy)
918  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][SPR] SpreadCoin | True Decentralization (No Pools) on: January 04, 2015, 03:17:59 PM
Another question I asked a few pages back...is there a way to show the top ten miners in a pie chart or something?  Would be interesting to know how many large farms are mining SpreadX11.

It should be possible to crawl the blockchain for which address has mined each block. I could probably script this if I could build a local block explorer...  Undecided

That may be as close as you're going to get though - just as it's impossible to assume true coin distribution via address as someone can have multiple wallets/addresses.

Remember that bitcoingroup video where Kristov Atlas had a rant about why was LTC worth anything at all when so many other coins were far more innovative and better featured... ?

Same argument applies to BTC. It's a centralised and increasingly regulated slug of a currency, in a rational market it wouldn't be worth over a hundred times more than DRK.
