Actually TBX is the only currency that can be "officially" mined parallel to the BTC-GPU-Mining.
Because it is very CPU-friendly.

But the premined - up to 3 years > 50 % - Big-7-Amount let the miners go elsewhere, because the mining success is mini and the rating should be very little.

This forces to go to an alternative CPU-friend.

How much would be "not" too ridiculous ? We could, you know, arrange for a publicly monitored Tenebrix faucet (ala bitcoin faucet) and I could donate the "extra" part to it, leaving myself with the not too ridiculous part for bounties and stuffs (my humble TBX laundry side project would likely die then, alas   Cry )


Incidentally, this would allow latecomers to get some TBX to get a feel for them.

I wonder if  the Bitcoinfaucet code is open...

P.S.:

A faucet with 1-2 million TBX milking out 2-4 units per a Google account login could keep trucking for looooooong...

I could create a basic faucet with Google authorization in a matter of hours, provided you get your daemon up and running properly.

Okay, could you also throw some fancy pattern-based captcha on top of it to discourage the new High-perfomance OCR bots, just in case there is a herder with large amount of IPs/GoogleAccs ?

If yes, then deal is done, and as soon as the linux daemon stops being a pissy bitch, we shall launch the faucet.

Would everyone gathered herein consider a donation of 1.5 mils to the faucet sufficient to consider the issue closed ?

Anyone who mines this without understanding how FPGA miners could be made to emulate CPUs is a moron. This currency was designed by Artforz for Artforz. Plus 3 years worth of mining pre-mined? Ridiculous....

Sorry to say but Tenebrix is a worst case marketing name.
Not only impossible to remember if you hear it once but such a name also gives a negative loop on the word of mouth effect.

So if you are serious about your business you need to treat the naming of the coin serious.

Other than that good luck!

Basically, that's exactly like DeBeers - they do indeed control a large piece of (until not so long ago, pretty much all) diamond market, but they actually use it to ensure that the market is viable and the diamonds are expensive.

Selling off when you have a VERY large chunk is just plain stupid.

But I actually like the Faucet idea... Yes, I will be less phat and my laundry project will have to scale down quite some, but hey, on the other hand people like them coin faucets and them faucets solve the whole "first adopter" complaint by quite a lot.

And 1.5 mil will keep the faucet dripping for a looong time.

So, you propose using a $700+ chunk of hardware to emulate (which necessitates losses) a $100+ chunk of hardware ? Sorry, but would you like to buy my bridge ?

I accept BTC, GEG, SC-1, NMC, i0, ix, TBX, USD LR and pecunix as viable forms of bridge payment.

As for 3 years worth of coins, less now since I have pledged 1.5 mil to the TBX Faucet project.

Nice walkthrough. Downloading the zip from github (clearly I'm not a linux person) I couldn't get it to compile, so I followed your steps and used the git app. I think the client compiled, but when I try to run it I get this:
Code:
x@x:~/Downloads/Tenebrix$ ./bitcoin-qt
bitcoin-qt: src/main.cpp:1754: bool LoadBlockIndex(bool): Assertion `block.hashMerkleRoot == uint256("0x4e77ffdc1baa20ffffab9d901f418f7496b2a710e462ac4047accdb8b3b774f9")' failed.
Aborted
Anyone know what's up? The Windows binary runs great on Vista & 7, but I'm curious as to what my ailing netbook running Ubuntu can do.


did you copy the config to file?

Code:
$ cat README.rst
Tenebrix - a cryptocurrency with solid stance in favor of CPU and against GPU
PoW based on scrypt

Based on multicoin-QT

ATTENTION!!!
[b]DON'T FORGET TO PLACE tenebrix.conf into your[/b] [s]APPDATA or default tenebrix folder (%APPDATA%\tenebrix on Win,[/s] [b]~/.tenebrix/ on Unixes[/b])
Probably not Wink

now you really owe me a 25 tbrix Smiley
D'oh, now I feel stupid. Sure enough, that was it. Send along your receiving address. Smiley

Trying to install the linux miner didn't work so well. I got stuck with the same thing Bobnova posted a few pages back, and installing a libcurl4-dev pack (the first listed) didn't help as suggested by ArtForz. So, I downloaded wine and the windows miner and that worked just fine first try. Not ideal, but eh, it works.

So now I'm getting ~1.83 khash/s on my Phenom X4 955 (OC'd to 3.8GHz, stock clocks it gets 1.55 khash/s; three threads only since the fourth core is mining), 0.4 khash/s on an old 2GHz C2D laptop (two threads) and a whopping 0.32 khash/s (one thread) on my Ubuntu-running 1.6GHz Atom netbook. I'm actually pretty impressed, 0.32 seems good for a first-gen Atom compared to that C2D...

Do bear in mind that current CPU miner for Tenebrix does not employ a whole bunch of clever tricks and is not optimized for 64-bit architectures.

So in the future, slightly more khashes could be squeezed out of ye olde cpus.

Yep, it's still very unoptimized.
Just compiling scrypt.c in cpuminer with -O3 on amd64 linux ends up at 3.28kH/s/core on a AthlonII @ 3.6GHz.

I was going to PM lolcust about this but I might well ask publicly now that the issue of the pre-coins has come up.

I run a wiki about human rejuvenation at http://www.rejuvepedia.org and I am hoping to secure some donations.

One of the Rejuvepedia spin-off projects called "Project In-Utero" will soon have a website and forum (hosted at www.in-utero.org) that will hopefully sprawn a collaborative online community around
the idea that we can completely rejuvenate a human body over 9 months by using a tissue engineered and wetware controlled placenta and uterus. The person being rejuvenated will
effectively be spending 9 months back in the womb and when they come out will still be an adult but have younger looking skin than a teenager as their body will be completely rejuvenated.

The placenta will feed the person with stem cells and effectively the person will be in a state of anaerobic respiration. I have a theory that there is something very special about anaerobic respiration that makes cells
proliferate as they don't need to repair oxidative damage.

Of course this will be tested on mice (and other mammals) long before we start to proceed to work out how we could ethically proceed to do this with humans.

I want to put forward some bounties to develop the art-work or animations showing this happening to help inspire people and capture their imaginations. I am hoping to secure some coins towards these bounties but I will contribute to them myself as well.

Lolcust: could you possibly contribute some Tenebrix to this project?

I have to get ready for work now but my contract is ending in a few days time so I will have a lot more time to work on this then.


I know next to nothing about biology, but I might contribute.

...
That whole i'll build a bigass womb and unbirth your ass so you can get younger by cutting the oxygen to your brain thing doesn't sound all that scientific...i would hold my money till it undergoes the peer review process and stuff.

(I dont always get new reply notifications, pls send a pm when you think it has happened)

Wanna gimme some BTC for any or no reason? 1FmvtS66LFh6ycrXDwKRQTexGJw4UWiqDX Smiley

I think having any premined coins is ridiculous. You make the rules for the currency, you should play by them just like anybody else.

Okay,  that is a respectably consistent, if restrictive, opinion.

However, do you at least admit that at least theoretically  while, of course, premining can be abused, it enables one to do very nice things for the project as a whole, like for instance pay programmers (at least after the coin starts exchanging), set up a faucet that doesn't run dry for a loooong time, run a fanciful "give old cryptothingies and a small fee, receive fresh coins cryptothingies " service Cheesy ?

It should be possible to get it scrypt crunching, but it is off course impossible to tell how good a scrypt cruncher will it be.

I think you should try, it will be an interesting project irrespective of eventual performance outcome.

given that in fact, the existence of the fund was both explicitly stated in first post and in the config,  I am somewhat surprised that you have missed something that was never concealed in the first place.
in the first post you should not mention the existence of the fund but also it's size - that would be transparent


is it possible to modify the client so that it considers all coins from block #1 invalid?

1) No, the point is to create a system which limits minting opportunities in an systematic  mathematically reliable manner. That's why my little fun-d is less noxious that "protection racket in the blockchain". I had one, and only one, opportunity to premine - system will never give me another such opportunity.

Now, if I had a pseudo-tax, the system would have been given me a bunch of coins generated by other people's hardware and electricity with every block, no matter what Wink

Know what? You can even have cryptocurrencies where only Select Few have the right to mine and can have cryptographic voting as to whether include or expunge someone from the Select Few (Coinhunter, I am giving this idea away fo' freeeeee   Grin )

2) Being able to hire programmers, organize PR (that is, if I can convince myself to abandon the "do not spam twitter" principle which I so far am not successful at), and run a phat laundry is hardly really a case of where one can "rule it" (all or part).

Now, if I could decide who mines and who does not, that would be a case of "rulership", but I can't be bothered to mess with such a tricky system Wink

given that in fact, the existence of the fund was both explicitly stated in first post and in the config,  I am somewhat surprised that you have missed something that was never concealed in the first place.
in the first post you should not mention the existence of the fund but also it's size - that would be transparent

Technically, the fund is specified in the config, so it's not particularly hidden, and besides we seem to have reached the agreement that the amount of premining that is "proper" is an intractable issue.

The only answers are either "no premining at all" (and thus no fund-shmund, period), or whatever "feels right" which is bellyfeel-based decision making approach (and since we have different bellies, we will have a hard time coming to agreement as to how much is too far, and when does one's grasp exceed grasp Wink )


is it possible to modify the client so that it considers all coins from block #1 invalid?
No, but it is possible to put coins into a faucet so that they can not be touched by the voracious Lolcust and slowly trickle down onto the late-adopters.

If you consider faucet donation of 1.5 mil to be insufficiently fair, I would like to hear what fund size would you consider appropriate - after all, I might agree and donate more to the faucet (though it will cut into my laundry side-project, making me quite a sad panda  Cry )
