Topic: [Datacoin] External miner released! - page 5. (Read 10525 times)

linux pretty please?

wooow, how much times when you get 5 blocks on these PCs?

And what's the "ACC" mean?

No. The chains per day stat is generated by the internal mining code of the wallet.

Quick question: is the chainsperday stat on the datacoin daemon supposed to give a reading when you are using an external miner?

I'm just wondering because mine is sitting at 0, other than that everything seems to be working correctly. I got a big boost from using the Sandy Bridge mpir on my i7 4770 as well.

Currently running 6 cores on (1) i7-4770 and 7 cores on (12) i7-3770. I save the last core on the 3770s for gpu litecoin mining overhead.

How many PCs you got?

5 and counting. Literally just got one 23 minutes ago.

Has somebody found any block with this miner yet?

seems that solo mining with home computers can be profitable again?

There is (at least) one wiki*eaks document (a leaked document) stored into the bitcoin blockchain.

Thank you mumus for fast reply!

Hi,
I've just updated the source at https://github.com/hg5fm/jhPrimeminer with some fixes related to what MrMagic suggested in his previous post.
Now the miner will accept "-getwork" command line parameter that can be used to do the classic solo mining using datacoin wallet and getwork protocol. It also should have some fix that may prevent the wallet crashing problem reported by some users.
A precompiled binary can be found here: https://mega.co.nz/#!mRMnSAwC!ZoAHgBVIMIOthnRQOq9ukRWWz-hvayNyshB1oXpHcXU
Compiling the source can be done using Visual Studio 2008/2010/2012/2013 or by installing the Windows SDK.
If someone doesn't want to install Visual Studio here is a little guide to compile it with windows SDK.
1. Download and install the Microsoft Windows SDK for Windows 7 from: http://www.microsoft.com/en-us/download/details.aspx?id=8279
2. Download and extract the jhPrimeminer source code from: https://github.com/hg5fm/jhPrimeminer/archive/master.zip
3. Open the "Windows SDK 7.1 Command Prompt"
4. Change the current directory to the extracted jhPrimeminer source location, for example:
5. Compile the miner with the following command:
The jhPrimeminer.exe will be located under C:\jhPrimeminer-master\src\bin\ directory
In order to run it you will need also the mpir.dll which depends on MS Visual C++ runtime. One can be found in the jhPrimeminer-v8.2.zip mentioned above.
6. Run the miner
Of course replace the username and password with your values specified in the wallet's datacoin.conf

You may want to test that your miner and configuration works well using the datacoin  testnet network where the difficulty is very low so you can find block easily.
In order to do this run the latest wallet (I've compiled form the latest code today, earlier versions may not work on testnet) with the following command:
Then run the miner:


Regarding to building the miner with different compilation flags targeting some CPU features like AVX, SSE3, SSE4, etc., I've found no significant performance improvement in my tests.
More important is the version of the mpir.dll that is used by the miner which can lead to 20-30% improvements with specific CPUs.
A package of some precompiled mpir.dll can be found here:  https://mega.co.nz/#!DMdBCSII!ZYAYTzxeNJu_JzKVpUFNa01ehTYfHQHH_leijY28wbQ

I've also tried to solo mine datacoins with one of the Linux port of the jhPrimeminer that was forked form https://github.com/hg5fm/jhPrimeminer at an earlier stage. It should support getwork protocol but  looks like it is broken now. I'm working on the fix and will post and update when I have something.

did anyone have active testnet node? my wallet in testnet cannot sync...

I just want to check my config is right, so I want test it in testnet.

And lets say it:

Illegal content is only illegal from someones point of view.

We all agree that pedobear is bad guy, but we all agree that some documents should be acessible to all, even if some people say they are secret.

We are making free decentralised data service, which cant be closed that easily.

We are making Internet more free.

I answered this questions a lot of times. Firstly, all coins that support messages and small data can contain such content - Namecoin for example.
Secondly, files stored in blockchain are not just files on your harddrive - they're turned into blobs and encrypted into blockchain. You need special soft (wallet) to get these files, so it cannot be easily proved that you have some illegal content. I can write a program that takes definite bytes from Windows common files and writes them to file '1.jpg'. This program won't contain any such content, but if you run it, you can get illegal picture from windows common files. So do you think that all Windows users can be arrested in such a way?

Can someone explain this to me:

Datacoin allows anyone to place entire files permanently in its blockchain - so how long until someone uploads illegal material and then everyone who runs a Datacoin node can be arrested?

@MrMagic:

Good job!
I was able to sucessfully compile it with VS2013 in AVX & non-AVX versions.

Yes. I have 12 machines running on my one wallet.

So we can make a private pool with someones wallet ?
