Okay, linux users havign segfaults should try changing daemon=1 to daemon=0 in config.

Interestingly, doing that on windows increases the likelihood of GUI becoming unresponsive and makes trying to "make it live again" by rightclicks on tray icon less likely to succeed.

Oddly lin and win are at counterpoints here.

Investigating

cryptocurrency with solid GPU resistance

Why would we care about that?

Your question is so awesome I'll add it to the FAQ.

Well, for starters, Tenebrix offers you opportunity to mine some coins that will be eventually exchangeable with spare cpu cycles of your awesome 4-card mining box that it doesn't use anyhow:)

Second, it makes for a more diverse adoption base since there is no "you must have a fairly loud and specific bit of narrow-purpose hardware at least THIS cool to even try mining" effect (pools will still be kings though)

P.S.:
Coin dispensing will begin soon, in order of address posting, no less than 5 addresses will be processed Smiley

We heard you like mining, so we put a miner on your miner, so you can mine while you mine.

Note: try changing -s in the miner batch to 3, 5, or 7. Experiment which is best for you.

Official Website: http://www.tenebrix.org

Hello everybody!

Allow me to introduce you Tenebrix, a cryptocurrency we (mostly ArtForz, but I contributed the name, some minor tweaks and the logo, as well as windows portability suite and cool genesis motto Wink ) have created to provide the community with a cryptocurrency with solid GPU resistance.

It implements a proof-of-work scheme based on scrypt, a cryptographic construct specifically designed to resist creation of efficient GPU, FPGA and even ASIC implementations. You can find more about scrypt and how it can improve your stamina, masculine appeal and performance here

Tenebrix is intended not only to become the first and the best of CPU-specific cryptocurrencies, but remain so in the future (that's exactly where the Tenebrix Protection Fund will go... That, usability/gui bounties, fixes and my dream of starting up a massive coin laundering "Historical Cryptocurrency Collector" Service Cheesy)

So, now I guess it's the FAQ time.

Q: Why would we care about that? (c) bitcoin2cash

A: Well, for starters, Tenebrix offers you opportunity to mine some coins that will be eventually exchangeable with spare cpu cycles of your awesome 4-card mining box that it doesn't use anyhow:)

Second, it makes for a more diverse adoption base since there is no "you must have a fairly loud and specific bit of narrow-purpose hardware at least THIS cool to even try mining" effect (pools will still be kings though)

Q:  What are the basic parameters, blocktimes and stuff, you know ?

A: 1 block per 5 minutes, retargets every week, no upper bound on mining and 25 coins per block.

Q: Oh noes inflation!

A: No, Tenebrix, just like Geist Geld, is actually deflationary in a way, and in fact allows for "coin regeneration" to happen, but I believe it would be best to contain discussion of "no upper bound mining" and "Coin regeneration" to Geist Geld thread

Q: Why the name ?

A:  Initial idea was Tenebris, because it is a cryptocurrency that thrives in the shade of any major GPU-mining operation, peacefully enjoying   the spare cpu cycles of miner rigs (of which they have a lot)

However, it was determined that plain Tenebris is kinda meh and lacks bite, and thus Tenebrix, the cryptocurrency with solid stance in favor of the CPU and against GPU, was born

And yes, I abhor the %insert_word%coin naming scheme.

Q: What if in The Future Nvidia will make GPUs based on genetically engineered rat neuron cultures that will crunch Scrypt like so much stale cheese ?

A: Efforts shall be taken not only keep up, but peek ahead of the curve and ensure that tenebrix remains CPU friendly and GPU hostile, no matter what kind of GPUs future science will throw at us. Being  FPGA and ASIC hostile is harder, given their flexibility, though frankly, if someone, at some point in time, will be willing to throw that kind of money and engineering skillz at mining Tenebix, that already makes Tenebrix a success  Grin

Largest Tenebrix bounties will be for  finding ways to implement Tenebrix mining on GPU hardware in a manner that outcompetes a CPU of equal price range by a certain margin (under discussion, suggestions welcome), and ready to apply fixes that return Tenebrix its status of a CPU-friendly, GPU-hostile cryptocurrency.
Hopefully, Tenebrix will bring together talented people with interest in designing systems resistant to creation of efficient GPU (as well as FPGA and ASIC) implementations a-la scrypt.

And, of course all results of Tenebrix project, produced via bounties or otherwise, will be free and open-source  !

Q: What about botnets ? CPU mining is a haven for them, and they are eeeeeevil!

A: Well, actually, that's an interesting topic to discuss.

First and foremost, if it is possible to make a CPUsclusive cryptocurrency (and it seems that Tenebrix makes quite a solid practical argument in favor of possibility of such a feat), then it will be made eventually. So not making Tenebrix would have achieved nothing.

Second, I am firmly convinced that botnets, by virtue of need to remain somewhat covert, will not abuse their host machines too heavily with TBX minning, taking spare cycles here and there without encumbering the user too much (otherwise the malware will get noticed and exterminated), and assuming mining is lucrative, will avoid using infected machines for things that are likely to get a FBI clown car visit the formal owner of the infected box (such as transfer of highly illegal materials and attacks against legitimate infrastructure).
Thus, Tenebrix, should it succeed and achieve popularity, will lead to overall calmer, milder internet for all Smiley

Q: I heard you may have taxes...

A: NO ! Never ! Except for standard transaction fees, Tenebrix is a sworn tax heaven !

Q: I heard you premined, you bad bad person...

A: Well yes, I premined 7 million coins. Why so many - well, to be completely blunt and honest, I got a bit tired of a discussion of how much should one premine that I had going on and used the premine value from GeistGeld. Perhaps not the wisest decision, but worry not though - I will use 2 millions do fuel verry slow (no more than 4 TBX per user, may get less if their price rises) faucets with strong user ID (Google Acc + captchas), and about 1.5 mils are set aside to help recruit developers and sustain support for no less than 6 years (you gotta agree that it is a looong road and a lot of money-gulping things can happen)

I will use the rest to start a unique transaction-anonymization service, using them as a buffer of sorts (old TBX + fee enters, crispy TBX from reserve exit in a certain randomized manner. In the end, I keep only the "fees" and the "old TBX" that entered the service are retained to form a new buffer as old one shrinks. Thus, the amount of TBX destined for buffer remains static forever, and never ever enters circulation, sequestered as a "transaction mixing service buffer" forever. I think we can all agree that stronger transaction mixing is a good thing and a benefit to community Smiley )

Q: Will you pay people these new coins for posting about the great awesomeness of Tenebrix and its solid stance against GPUs on Twitter and deadnotebook livejournal ?

A:  I dunno. Haven't made up my mind.

Q:  What do you call a coin with this thing ?

A: Whatever you like! I personally like "brix" due to association with obscure local computer jargon for a CPU and general appeal of solid, reliable building materials.

Q: Will you give away brix like you did with Geists ?

A: Yup, about 3825 brix are up for grabs, and will be equally divided among first five people to post their Tenebrix addresses

Q: WHY DID YOU GUYS DO THIS WHY WHY WHY?!

A: If a technological feat is possible, man will do it. Almost as if it's wired into the core of our being.


Q: Where are the windows binaries ? (text emvastened by popular demand)

A: Here, with neato QT GUI and wrapped in a portability suite so that you don't have to set anything up and have easier time backing stuff up.
The multithread miner is included with a startup script (START_MINING) that is interactive, gives hints, and has pre-set work-out-of-the-box download-and-mine defaults !



Q: Where are the sources ?

A: Here, on github https://github.com/Lolcust/Tenebrix

Q: What about multi-threaded miners ?

A: Glad you've asked ! A mod of Jgarzik's reference CPU miner is included with the portable Tenebrix bundle (minerd, a launch .bat pre-configured for 2 threads, default login/pass and localhost is included. Bear in mind that if launched without command line options the miner crashes, which is known to confuse and disturb users Wink )

Miner sauce here https://github.com/Lolcust/Tenebrix-miner

Q: Pools ?

A: Several weeks after first Geist pool launch (pssssst, you heard nuthin ! )

Geist only uses testnet folder due to legacy from multicoin.

OKAY THAT DOES IT Cheesy

I will change the default folder layout in the upcoming update (Don't worry, your "old" geist wallets will still reside in <datadir>/testnet so you could copy them over to new location and thus no ghost monies are expected to be lost)

Does that mean that GEG isn't experimental anymore?  Is it a "real" chain then?

It's still experimental, but it's real (in the sense there is an exchange in the works, and sooner or later pools) to the approximate extent (some) other alt-coins are "real"

BTW, what defines a "real" alt-coin ?
624  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANNOUNCE] New alternate cryptocurrency - Geist Geld on: September 23, 2011, 07:53:22 PM
Yeah, there you go. Donation sent.

Thank you.  I didn't even think about adding a GEG donation address to the page, as I didn't add a Bitcoin testnet one.  They are testnets and the coins have no value, have they?

Geist only uses testnet folder due to legacy from multicoin.

626  Alternate cryptocurrencies / Altcoin Discussion / Re: [ANNOUNCE] Geist Geld now has a website! on: September 23, 2011, 06:00:00 PM
I do have a request of Geist Geld coins, can we have an easy copy and paste address function?  As far as I see, at the present, sending from one account to another is not that easy as I can't seem to be able to copy and paste the sending address.

Well, crutches allows one to select text in the console and copypaste it (how exactly is copypasting carried out depends on your settings)
627  Alternate cryptocurrencies / Altcoin Discussion / Re: Geist geld, first two blocks contains 7769999+7769 coins generated on: September 23, 2011, 05:54:34 PM
How many are currently in existence?

About 401457 spread among miners and about 7769999 (slightly less, because I sent bounty to Cosicminer for a fanciful pic) in the (Laundry buffer + Bounty fund)
628  Alternate cryptocurrencies / Altcoin Discussion / Re: [ANNOUNCE] EnCoin - An alternative with a completely different paradigm on: September 23, 2011, 05:36:11 PM
Could you outline, in layman's terms, how does the system physically measure energy expenditure that goes into a "coin" ?
629  Alternate cryptocurrencies / Altcoin Discussion / Re: Geist geld, first two blocks contains 7769999+7769 coins generated on: September 23, 2011, 05:08:22 PM

at the rate of generation of GG coin.... how long before this amount of pregened coins becomes mouse nuts (i.e. for example less than 3% of all in existence)?

Lolcust?

I think someone in the thread gave estimates of three months until the common mass of Geist outruns my little superfund.

What perplexes me most is the strange idea that 7 mils on an encrypted wallet .dat stored on a thumbdrive will affect the behavior of your average  speculative cointrader.

By that logic, "vanilla currencies" speculative traders should all be nearly infinitely terrified of all fiat currencies, because not only there are players who have large amount of that stuff readily available, but there are players that can make an arbitrary amount at, theoretically, a drop of a hat Smiley
630  Alternate cryptocurrencies / Altcoin Discussion / Re: Geist geld, first two blocks contains 7769999+7769 coins generated on: September 23, 2011, 04:50:36 PM
90% the pre-generated coins, blocks the rise in the price in future exchange markets.
You killed own the project as currency for speculation is still at start, i think.

You seem to be under impression that x-coin exchanges are affected by "potential" coins on the market, which is a strange idea that goes against both what happens on various alt-currency markets and what happens with bitcoin (which has a remarkable amount of "dormant" coins that don't move anywhere and are not traded, like, at all, and so far the fact that there is a fairly large proportion of overall of bitcoin count to date that is currently "sequestered" but hypothetically   might enter the exchanges when the stars are right is causing remarkably little panic and awe)

Are you, by chance, proponent of efficient market hypothesis (esp strong variety) ?
631  Alternate cryptocurrencies / Altcoin Discussion / Re: Geist geld, first two blocks contains 7769999+7769 coins generated on: September 23, 2011, 02:41:18 PM
Well, if you read the thread you already know that Cheesy

Do note that first 7769 are part of Genesis block, which I never really figured out how to tap into, so they remain to Satoshi or whomever has the original Bitcoin genesis keys.
632  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANNOUNCE] New alternate cryptocurrency - Geist Geld on: September 22, 2011, 11:47:14 PM
When I finally get the poor thing going on the exhange's server Cheesy. Which I am sorta moving towards......
633  Economy / Speculation / Re: EVERYONE CALM DOWN on: September 21, 2011, 09:40:02 PM

Sadly, Geist Geld is not ready for bitcoin collapse Sad

However, Geist Geld is ready for yet another SolidCoin collapse Cheesy
635  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANNOUNCE] New alternate cryptocurrency - Geist Geld on: September 21, 2011, 03:56:16 PM
In .gg/bitcoin.conf change printtoconsole=1 to printtoconsole=0

ggd -datadir=/home/ama/.gg getinfo


I see.  So I need to add the -datadir parameter on the command line all the time, OK.

~$ ggd -datadir=/home/ama/.gg getblockcount
12605

Yep!  Finally!  I think it'd be very convenient to make all this information needed to run the daemon easily accesible to the newbies.  Thank you for all the help.   Smiley

Well, I think I'll put a bounty on a linux tutorial (win users can just download "Crutches" portability suite / PGUI and fire away), since I'm quite clumsy with them linuxes.

Hm, I guess 500 GG would be fair....
636  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANNOUNCE] New alternate cryptocurrency - Geist Geld on: September 21, 2011, 03:15:53 PM
Hm, could you post the contents of the config you are using with Geist to www.pastebin.com ?

It's short enough to paste it here:

~$ cat .gg/bitcoin.conf
rpcuser=user
rpcpassword=password

I use equivalent files for all the *coin.

Well, that kills the Geist.

It's a multicoin fork, so it takes a lot of vital stuff (including Genesis block properties) from config.

I guess I will make that very explicit in first post and on site lol.

Use default config supplied with sources (though you might want to change rpc username and password)
637  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANNOUNCE] New alternate cryptocurrency - Geist Geld on: September 21, 2011, 03:05:04 PM

I don't have any port or rpcport set.  

That is not normal, default Geist config should have both of those.

Geist is different in how it handles stuff from config (due to being a Multicoin fork) and thus some values (port, portlisten, ntp, enablefullretarget and many others) need to be there.

Please see "default" Geist config, it's in the Config+Blockchain folder that should have gotten fetched from Git, and also in the Git source's root

I started getting a few of these this morning:

ProcessBlock: ORPHAN BLOCK, prev=00000000000049aaab5e
ProcessBlock: ORPHAN BLOCK, prev=0000000001b0b1aa5309
ProcessBlock: ORPHAN BLOCK, prev=00000000016e2617943a
ProcessBlock: ORPHAN BLOCK, prev=0000000001aa515daf6a
ProcessBlock: ORPHAN BLOCK, prev=0000000001acdbf89780
ProcessBlock: ORPHAN BLOCK, prev=0000000001c23469de6c

I have the log piped to a text file if you want it.

Please PM it to me

639  Alternate cryptocurrencies / Altcoin Discussion / Re: [ANNOUNCE] Geist Geld now has a website! on: September 21, 2011, 02:17:03 PM
Well, since I have little access to an exchange's internals and am a graphic designer by trade, I am hardly in a position to dispense advice as to how best secure an exchange's wallet, though not having it on the machine that runs the exchange's web frontend seems both sane and doable
640  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANNOUNCE] New alternate cryptocurrency - Geist Geld on: September 21, 2011, 02:12:51 PM
Um, did you try putting quotes?

:~$ ggd -datadir="/home/ama/.gg/" ?

Maybe try using a different  datadir name, one with no dot in it (random suggestion) ?
