[Announce] Fairbrix relaunched!

[coblee]

Fairbrix is a GPU-unfriendly coin based on Lolcust's Tenebrix. The main difference between Fairbrix and Tenebrix is that Fairbrix does not come with 7.7 million premined coins. In fact, only 100 blocks were premined. Like Tenebrix, Fairbrix uses scrypt for proof of work. This makes it hard for GPUs to calculate proof of work. So it's more cost effective to use CPUs for Fairbrix mining.

Fairbrix details:
 - scrypt proof of work
 - 25 coins per block. this stays the same forever
 - blocks found every 5 minutes on average
 - 2016 blocks difficulty retargeting (1 week on average)
 - default rpc port: 8645
 - default port: 8591 (open this in your router)

Anyways, here's the client source:
    https://github.com/coblee/Fairbrix

Windows binary and miner:
    https://github.com/downloads/coblee/Fairbrix/fairbrix-win-client-v1.0.zip

Linux daemon:
    https://github.com/coblee/Fairbrix-daemon

Currently, you must use one of these miners that uses Scrypt:
    https://github.com/Lolcust/Tenebrix-miner
    https://github.com/ArtForz/cpuminer - Fastest but experimental

Also, you may need to configure it for your machine to get the optimal speed. Check the README file. Somewhere on the forums, people have suggested running configure like this:
    CFLAGS="-march=native -O3 -Wall -msse2 -msse3 -msse4.1 -msse4.2 -msse4 -mavx" ./configure
OR
    CFLAGS="-march=native -O3 -Wall -msse2 -msse3 -msse4.1 -msse4.2 -msse4" ./configure

To mine, you will need to copy the fbx.conf file to:
    Windows: C:\Documents and Settings\username\Application Data\fairbrix
    Mac: ~/Library/Application Support/fairbrix
    Unix: ~/.fairbrix
And make sure you change the rpcuser/rpcpassword in the fbx.conf file.

Here's a Fairbrix block explorer:
    http://blockexplorer.sytes.net/chain/Fairbrix

Pool and exchange should be coming soon.

compiles and runs on Gentoo linux and Kubuntu
If you do not like to use the GUI client as miner (see config file) you can use tenebrix miner but do not forget to add the URL and correct port

Code:

./minerd --user 1 --pass 1 --url http://127.0.0.1:8645

Very good. I have two machines with decent CPU's up and running. Now to take my dog for a walk

[worldinacoin]

I am trying it out on one machine.

[caston]

I'm only get three connections. What is the port I would need to forward on my router to  get more connections?

Oh here is my FBX address: fF6o8LeDAfswEpMbCW8BqaqmzMWS7TGgew

I'm very glad I went out and bought a new 6 core Phenom II. It's simply running laps around my 4 core Athlon II

Any way to get a zip for us Windows users?

You can get git for Windows. I know because I installed it on my notebook at one stage.

Try this one:

http://code.google.com/p/msysgit/

You'll still have to build the source though which on Windows would be more tricky than on Linux. You probably need someone to release binaries for you. The best thing I would recommend though is to dual boot between Windows and Linux and have a bitcoin build environment ready on both systems.

Well, part of the appeal of CPU mining is simplicity.  That was part of the goal for Fairbrix.  A zip file with all the compiled code helps with that.

Getting some of such errors

Yeah, I wouldn't be to worried after each new currency comes out there is always a crash and you can buy lots of coins very cheap before they start to rally.

how did you start the miner?
Is you client running?

[EskimoBob]

please read Fairbrix / README.rst : https://github.com/coblee/Fairbrix/blob/cpumine/README.rst

It is probably easier to keep one file updated. If something is still missing, please speak up and or or submit your updated to git.

Cheers!

The client dropped to zero connection, I think thats what causing the problem.  Is there any ports I should unblock?

its all there

[Bobnova]

Working for me.
Edit the conf file and change "gen=0" to "gen=1" to tell the client to mine.

Compiled on linux beautifully.

[randomguy7]

Does this work headless?

Have you been getting blocks this way? Most of us are using a custom modified minerd.

[worldinacoin]

I opened the port, it still drop to zero connection once in a while

[Bobnova]

Lots of blocks, 9 in the last 11 minutes.
No way to see what kh/s though.

Switched to minerd for giggles.
7 threads of 1.62Kh/s brutality.
