[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.

[EskimoBob]

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

EDIT 14:56:26 UTC 2011  : Good news for window$ users:  http://www.mediafire.com/?9gc28oo1s00lhhz 

[caston]

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

[caston]

I am trying it out on one machine.

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

[michaelmclees]

Any way to get a zip for us Windows users?

[caston]

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.

[michaelmclees]

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.

[worldinacoin]

Getting some of such errors

[2011-10-02 21:49:32] HTTP request failed: The requested URL returned error: 500

[2011-10-02 21:49:32] json_rpc_call failed, retry after 30 seconds

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!


 

[worldinacoin]

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?

[caston]

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.

[dust]

Looks good!  Mining with tenebrix minerd.

[EskimoBob]

For window$ users:  http://www.mediafire.com/?9gc28oo1s00lhhz 

[iopq]

note that the batch file starts 5 threads, not 2
just edit that value if you're using the START_MINING2 file and want 2 threads

[mrx]

I only have a Ubuntu server, that is, without X.

Does Fairbrix have standalone daemon now? Or how do I run it under text mode?

[SolidBitShop]

Hi.

Im having difficulties runing several CPU under one client.

I have opened the port so there is no blocking of it.

I have tried with daemon=1 and rpcallowip=the others machine IP (question how do I add a range of addresses to RPCALLOWIP command or at least two addresses?)

None seems to work. The miner can't connect. It worked fine for normal GPU clients for the BTC IXC SC I0 But I can't run this on several machines any thoughts?

[iopq]

fairbrix chain just got owned
wud

balance: 0

[caston]

Anyone else's coins just vanish? Maybe we all had the same private keys?

[froggy]

Yup, whoosh, gone.

[r3v3rs3]

140 blocks orphaned, wtf?!

...and every new block disappears. 

[iopq]

140 blocks orphaned, wtf?!

more like 1500 blocks orphaned

[r3v3rs3]

ofc, but these 140 were mine up to some minutes ago.

[dishwara]

more than 30 minutes of mining with 2 threads & ZERO coin.
blocks 1609

[freequant]

Nevermind, Fairbrix can be re-relaunched.
Fairbrix, the amnesic coin

[caston]

Maybe there was a block chain split and most of us were on the wrong side of it?

[EskimoBob]

Maybe there was a block chain split and most of us were on the wrong side of it?

what that even means?

[caston]

I mined 25 coins now with a new wallet.dat file but I just checked any my other machine that I hadn't given a new wallet.dat file to has done a block as well.

Arggh.. I was getting ready to go to bed thinking i'd probably have > 5k coins in the morning.

You gotta see the funny side in this though.

[soptik]

Yes, my balance goes to 0 FBX too.

I did little test. I used my backed wallet (backed up at block 989) - i have confirmed 400 FBX in it. After I started gui, it takes more then one minute to start downloading newer block (although I had 3 connections after few second after gui started). And when app finally start downloading newer block all my balance was reseted to 0 and older transactions become unconfigmed

[caston]

The TBX price is crashing now too!

[twobits]

Maybe there was a block chain split and most of us were on the wrong side of it?

Yeah, probably someone with a lot of cpu power was disconnected from the rest of the network and  reconnected with their block chain or something similar.   Wonder if it was on purpose or not.   

[caston]

[phelix]

is there some way to check difficulty?

was the starting difficulty the same as with tenebrix?

edit: okok. just point your favorite bitcoind / tenebrixd client at it with a getinfo or getdifficulty 

[Lolcust]

wtf, I left my notebook running with fbrix for fun, and now all of the coinage it mined is gone.

How... unpleasant.

[coblee]

wtf, I left my notebook running with fbrix for fun, and now all of the coinage it mined is gone.

How... unpleasant.

Yeah, it was unpleasant. Most of the blocks I mined were orphaned as well. It seems like someone did a 51% attack on it.

[Bobnova]

Mine too, obviously.
Got >1kiloFbrix now though.

[phelix]

minerd does not seem to find anything.. neither yaay nor boo 

[freequant]

I confirm the chain is back on track.
All it needs now is to garner enough hashing power and increase in difficulty.

[caston]

I confirm the chain is back on track.

I reloaded my original wallet.dat and it still has no coins.

[worldinacoin]

Same here, maybe the difficulty is quite high. 

[freequant]

I confirm the chain is back on track.

I reloaded my original wallet.dat and it still has no coins.

That's because your coins were on the segment that was taken over by the 51% attack (or whatever happened that actually generated a longer strand).
I've also lost thousands of coins to the attack.

Coins mined after the attack are maturing normally and the hashrate is building up steadily.
The more time passes the less likely these will vanish like the first did.

[coblee]

I confirm the chain is back on track.

Yes, the relaunched fairbrix is back on track. Currently at block 4401, difficulty is 0.00390625.

Your libel is not even amusing anymore.

I wonder, is outright libel against the rules ^__~ ?

[caston]

Assuming there was a 51% attack whoever did that attack probably has a shitload of bricks. If any exchange is ever opened those bricks will be dumped there.

[Lolcust]

A shitload of frix, you wanted to say ?

Yes, and blockchain analysis would be useful in telling whether that is the case.

[bulanula]

Can't wait !

[worldinacoin]

Kinda weird, I had two transactions, but nothing is shown.

[coblee]

The next step for Fairbrix is a block explorer. But it will take a fair bit of work to create a daemon version of fairbrix similar to what lolcust has done with the tenebrix daemon. Let me know what your thoughts are and I will decide whether or not to spend time on this.

I'm in support of not having a FBX-BTC exchange for a while. I believe if an exchange starts up too early, the coin will become a pump and dump coin. If all you did was spend a few days mining a new coin and an exchange opens that values your coins at 100 BTC, why wouldn't you just sell all your coins and make 100 BTC for a fews days of work? I think that is what's happening with GeistGeld and Tenebrix. And when that happens, it's hard for a coin to succeed.

So what I want is to see if Fairbrix can stand on its own. See if people are willing to mine it without an exchange in sight. If people believe in the cpu-based mining concept without the premining, then they will continue to mine fairbrix... similar to how people mined bitcoins without an exchange early on. And if that happens, then it will become a viable alternative to bitcoin.

Cool idea.

[Bobnova]

The only reason to mine any coin (save for namecoin, sortof) is to exchange it.  You may be exchanging it for another "currency", or for USD, or for some physical item (though I doubt that, honestly.  Far too easy to scam someone as a seller given the non-reversableness of the payment), but exchanging is the point.
Once you take a look at how easy it is to scam someone who pays in *coins, exchanging for other forms of money becomes the only viable option.

If that's the only reason, then there's no point in the currency at all. The point of a currency is to buy goods. If it's just to exchange for another currency, then it's doom to fail.

[Lolcust]

Frankly, I think that FRX taking a different approach makes for more interesting experiment, but that does not necessarily mean a more viable cryptocoin.

Not at all, if you could easily dig up Zimbabwe Kronzes in your back yard and convert them to USD, wouldn't you do it?

Would you buy a $100 item with bitcoins directly?
Or would you use a central exchange/escrow service?

Any chance we could get a clear set of directions on how to do that with a Windows machine?

Download that and unzip it.  Double click "Start-Fairbrix".

After the client is running, double click the batch file "Start-mining".

You'll be mining Fairbrix in minutes.

There is a bug in keystore.cpp, AddKey. A 'return true' should be there. I assume this is missing from a bitcoin merge or some commit not pulled into whatever history the original fairbrix source came from. This is the bitcoin commit where it was fixed.

What's the ancestry of the code? ie. What commits was it forked from in bitcoin or multicoin? It makes it hard to audit what changes were made when the history is broken.

[Lolcust]

It's direct descendant from Multicoin Exp.

Damn we (I mean both myself and multicoin)  need a notable overhaul.

[doublec]

Damn we (I mean both myself and multicoin)  need a notable overhaul.

Yeah it's very hard to see what bitcoin fixes are missing. The keystore thing shows at least one is. I see sacarlson/multicoin-exp doesn't have that fix either.

What commit id was it forked from sacarlson/multicoin-exp originally? If I clone multicoin-exp and overlay the source from Tenebrix-daemon-exp then the diff I get shows it wasn't the master. For example multicoin-exp includes auxpow merged mining changes in src/db.cpp but Tenebrix-daemon-exp doesn't.

[Lolcust]

It was from the latest multimergermine branch, but it is a very very crude quick and dirty daemon.

I've...excised some of the aux stuff due to compile issues. Quick and dirty, tenebrix daemon is

[ama]

If my receiving address in the client is fL8P1QjhrwCmFQ4yLiVsDpAENXoQvzWXLR, should that show in the block explorer?

Not until you actually receive somthing with it.  Addresses only show up in the block explorer when they exist in the block chain, which only happens when they have at least one transaction.

[ama]

What do mined block have to do with your receiving address which actually never received anything?  I don't get it.

[michaelmclees]

Well, when a block is generated, the block explorer indicates that it goes to an address, with an amount of 25.

If one searches such address, they find the generated block.  I just assumed that mining a block was a form of receipt which would show up in the explorer.

[phelix]

a little marketing would do fairbrix good.


what about cleaning up the first post of this thread and summing up the features and the main difference to tenebrix? I do not see the early fork as a problem. also with tenebrix there probably are people having plenty of coins brix.

Who will start the first exchange? with api?  the startup will just not work without it. if one should start I will put up a small page with some basic stats. or if bitcoinExpress pays me some of his booty.

Why doesn't lolcust attack and kill this again !?

[iopq]

good idea, it's really a scam copycat chain

[worldinacoin]

It is very similar to Tenebrix no doubt, but I don't think how it is going to be a scam.

[bulanula]

It is very similar to Tenebrix no doubt, but I don't think how it is going to be a scam.

It has not got an exchange so I cannot pump and dump it !!!

[wknight]

What is there to kill? Until it gets an exchange I dont think people will mine it.. Unless you can trade it for something whats the point?

[worldinacoin]

Then, do not mine it.  No one is taking out a gun and forcing you to mine Fairbrix, there are quite a lot of other coins for you to try.

Sure, I will go with scammer's Bitcoin / Tenebrix. Or rather SC2 as that shows great promise ATM. All the other scam coins can perish.

I guess those early bitcoin adopters were stupid to mine 1000 bitcoins a day way back when there were no bitcoin exchanges around.

You have a good point there

[worldinacoin]

Tenebrix and GG founder did a good job having pools and exchanges in place.  But Fairbrix seemed to be more of a reaction to Tenebrix, not being able to get the exchanges or pools up does not mean that they are scammers, it just mean that they are less efficient or have less resources than Tenebrix and GG.   Who knows, maybe a month or two, such exchanges and pools may spring up.

[wknight]

I just like the fact that there isnt 7.7 million pre-mined coins.. a lot!

However, is there support behind this Coin? Development?

[worldinacoin]

Well, that's my worry too, that's why I am mining more of Solidcoin 2 as the earlier Solidcoin has shown a lot of good organization.

I will support it as much as I can. Unfortunately, you get what you pay for so to speak. With 7.7 premined coins, Lolcust has a lot of incentive to support Tenebrix. With 5% tax, CoinHunter has a lot of incentive to support SolidCoin. Whatever little fbx I have were orphaned by the attack. So I don't have that much incentive. The only reason why I spend time making it better or talking to pools and exchanges is because I feel responsible for it since I kicked off the relaunch.

So yeah, if you mine now when the difficulty is still low, you may get paid off handsomely if I manage to convince an exchange to support this coin. And if not, you would have wasted your time. Your choice! I will do the best I can.

I just like the fact that there isnt 7.7 million pre-mined coins.. a lot!

However, is there support behind this Coin? Development?

Well, that's my worry too, that's why I am mining more of Solidcoin 2 as the earlier Solidcoin has shown a lot of good organization.

I will support it as much as I can. Unfortunately, you get what you pay for so to speak. With 7.7 premined coins, Lolcust has a lot of incentive to support Tenebrix.

So, no hint of an exchange yet?

Also, when a chain is small like this, checkpoint updates are a good idea.

Thanks for the suggestion kano. I have already updated the source with a checkpoint at block 5000. Have not built another windows binary though. If an exchanges comes up, I will work on it.

I'm working on an exchange for GG and TBX, don't see why i couldn't add FBX. Will continue it after I get through with SC 2.0. Keep mining you FBX.

Is there any sense to devising some sort of standard 'coin API' to make it easy for new coins to be supported by existing exchanges?

Make sure you downloaded the cpumine branch. It should default to scrypt algo.

i dont understand, which branch?
can u give link?

If you gitcloned github.com/ArtForz/cpuminer then just compile and run the miner without specifying algo. I guess these options are left from the original cpuminer. They are irrelevant for Tbrix/Fbrix mining.

I got 1.78 KH/s per thread with Artforz's miner instead of 1.44 KH/s with Tbrix miner on a Xeon E5320.

8 Japanese scammers plot is just getting bigger and bigger.

Why don't you release the scrypt GPU miner even if it sucks ?
Why don't you make it viable on Intel CPUs ?
Why don't you pregenerate less coins ?
Why is there so much focus on exchanges already ( pump and dump much ) ?
Why yet another new CPU ScamChain all based on scrypt crap algo ?

See the pattern. Educate yourselves.

Oldminer - please go away.
It's one thing to be annoying, but in your case your both annoying and often wrong.
At least try to get most of the crap you say right (not all of it, just most of it)
It just make you look like a complete fool to everyone here on the forum who has an inkling of reality.

Is fairbrix succceptible to the tansaction spamming that hit Litecoin?  If so, could it be possible to get an updated Fairbrix client?  {Is TBX need updating too?}

I dont think anyone is working with Fairbrix any longer. Coblee moved onto litecoin so unless someone forks litecoin's code I dont think this will be patched..

TBX is in the same boat. Lolcust will need to update it though i havent seen any updates at all.

Yes, both fairbrix and tenebrix are susceptible to the same transaction spams. I do not plan to update fairbrix with the fixes. If anyone wants to keep fairbrix alive, feel free to take over.

[BeeCee1]

I won't be taking over, but since I have been digging around the litecoin code recently I decided to see how hard it would be to port my changes to fairbrix.  If people are really still interested in fairbrix they should put together a bounty pool to pay for future updates.

I made changes in line with what coblee did for litecoin, but modified them some to take into account the differing block times and current value of a coin.  I've also put in some other changes that I think will help fairbrix resist attack in the future.  All the changes I made relate to spam transactions being included or relayed by honest nodes.  If an attacker controls a significant portion of the hash power (a real possibility in fairbrix) he can bypass these checks and write 1,000,000 byte blocks.

You can get the source from: https://github.com/beecee1/Fairbrix   sorry, no pre-compiled binaries.

If you like what I have done, you can donate: fVQZtuBPRdVjbNskqHLB4e75Uq64dM9vWN

Here is a description of all the changes I made (and, you have the source code so you can verify it yourself).


In main.h:

From:
static const unsigned int MAX_BLOCK_SIZE_GEN = MAX_BLOCK_SIZE/2;
To 125,000 bytes:
static const unsigned int MAX_BLOCK_SIZE_GEN = MAX_BLOCK_SIZE/8;
Why: reduces the size of a block that an unmodified client will generate, helps protect against block-chain growth attacks


From:
static const int64 CENT = 1000000;
To:
static const int64 CENT = COIN/100;
Why: easier to read, no real change


From:
static const int64 MIN_TX_FEE = 50000;
static const int64 MIN_RELAY_TX_FEE = 10000;
To:
static const int64 MIN_TX_FEE = 1000000;
static const int64 MIN_RELAY_TX_FEE = MIN_TX_FEE;
Why: increase the minimum fee (when fees apply) to 0.01.  This is less than litecoins so you that the fee isn't quite so large when you send an output that is nearly a cent.  However, there is code elsewhere that will increase this fee for very small outputs.


From:
int64 nMinFee = (1 + (int64)nBytes / 1000) * nBaseFee;
To:
int64 nMinFee = (1 + (int64)nBytes / 500) * nBaseFee;
Why: This makes large sized transactions cost a more than before.


From:
if (nNewBlockSize < 27000)
To:
if (nNewBlockSize < 12000)
Why: since blocks are faster than in bitcoin, reserve less space for free transactions.


From:
        if (nMinFee < nBaseFee)
            BOOST_FOREACH(const CTxOut& txout, vout)
                if (txout.nValue < CENT)
                    nMinFee = nBaseFee;
To:
        BOOST_FOREACH(const CTxOut& txout, vout) {
            if (txout.nValue < CENT/10) { // outputs smaller than 0.0001
                nMinFee += nBaseFee * 10; // fee of 1
                smallTxOutCount++;
            }
            else if ((txout.nValue < CENT)) {
                nMinFee += nBaseFee;
                smallTxOutCount++;
            }
        }
Also add:
        if(smallTxOutCount > 15)
            nMinFee = MAX_MONEY;
Why:  This is the core change to limit dust spam.  Instead of a flat fee for small outputs charge a fee for each small output.  If there are more than 15 small outputs than don't allow the transaction at all.




In main.cpp

From:
if (dFreeCount > GetArg("-limitfreerelay", 15)*10*1000 && !IsFromMe(*this))
To:
                dFreeRelay = GetArg("-limitfreerelay", 5)*10*1000;
                dPartialRelay = dFreeRelay * 0.75;
                dNewFreeCount = dFreeCount + nSize;
                if( !( dNewFreeCount <= dFreeRelay
                    || dFreeCount < dPartialRelay
                    || IsFromMe(*this)
                  )
                )
Why: another spam attack mitigation. Don't relay more than (on average) 5000 bytes of free transactions a minute.  This is roughly equivilant to 20 normal sized transactions per minute, which is far in excess of the current volume.


Add:
        (nHeight == 15000 && hash != uint256("0x7c7fc755c19616fd3eb156b53dae2bbf058972e0731f3d0ee54785cc222f4bbf")))
Why:  add a checkpoint lockin at block 15000



From:
bool fAllowFree = (nBlockSize + nTxSize < 4000 || CTransaction::AllowFree(dPriority));
To:
bool fAllowFree = (nBlockSize + nTxSize < 1800 || CTransaction::AllowFree(dPriority));
Why:  Since blocks are faster in Fairbrix, don't allow as many exempted free transactions. (But they are slower than Litecoin's so allow more than that).



In wallet.cpp:

From:
int64 nPayFee = nTransactionFee * (1 + (int64)nBytes / 1000);
To:
int64 nPayFee = nTransactionFee * (1 + (int64)nBytes / 500);
Why: matching a change made in main.h

A bit belated I suppose, new windows binaries, based on BeeCee1's changes. 


dl links:

Qt client: (incl. source and miner)
http://www.datafilehost.com/download-1515503d.html

blk0001.dat, blkindex.dat and addr.dat: (optional, put in data dir if you cannot connect)
http://www.datafilehost.com/download-94ff2f8b.html


Data dir on windows7 is now
Users\<user name>\AppData\Roaming\fairbrix\
(i.e. same dir as with bitcoin and litecoin, the portableapps stuff is gone)
but it's
Users\<user name>\AppData\Roaming\fairbrix\data\
for all files except the config file.

The client will automatically generate the necessary dirs and files,
but you should manually copy fbx.conf to ...\Roaming\fairbrix\


I only added up to date checkpoint lockins,
in main.cpp

        (nHeight == 114000 && hash != uint256("0xf863ed327eede0641e1be668d43144e67c52c0785524faff2dd1a21bbdeabfbe")) ||
        (nHeight == 116144 && hash != uint256("0x7d0f9db5dbb9378ddd5bdd173b3c71fef8808690adec8ecc0bbb1b3648871b76")))

etc.


For some reason it's still
in https://github.com/beecee1/Fairbrix/blob/cpumine/src/main.h

static const unsigned int MAX_BLOCK_SIZE_GEN = MAX_BLOCK_SIZE/2;

all other dust spam limiting changes are in.


X64 version of cpuminer2.2.3 included
(virus scanners don't complain about the 64bit version)
and example batch files for solo mining.


Bugs: - Qt client window doesn't like being minimized (it doesn't actually crash,
        double click on task bar or notification area symbol to "wake it up" again)

As the creator of Fairbrix, I should chime in. First of all, Fairbrix is dead and I have abandoned it since launching Litecoin. Please DO NOT download any windows binaries and run them. They could actually steal real coins from your computer.

I'm going to lock this thread now.
