How does system respond ?
My idea doesn't cover multiple exchanges. It would only work with one. More thought would be needed to extend it to other exchanges if needed. This is what I meant by centralizing around the exchange. So for the 'one true exchange' idea I'd see one order book managing deposits, withdraws and orders. This is the entity doing the checkpointing. Perhaps other 'exchanges' use an API to access the order book and provide functionality on top.

Well, I suspect that the community would treat actual deployment of God-Emperor Exchange even less warmly than it treats large "future development/exotic laundry" premines.

Though I think that Ixcoin could do that with relatively little public relations issues... Maybe we should propose that to the fakepanese guy ?

Since the creator gave himself 7million TBX before its creation, assuming there are enough orders to fill (surely there aren't), he has $245k

I wonder, why it does concern you so much, is this some peculiar competitive sense, or are you just upset that I didn't donate any to the "Solidcoin 2.0 makefile restoration fund" ?
No, I am not a coin "fanboy" or anything like that. I just don't understand why people are using a coin that if/once it became mainstream, the creator would have more money than everyone else combined. Seems like a scam to me.

I think that if you read 1st post in the TBX thread, you know that I have a far more fascinating plan then just "cash out", a plan that pretty much requires a buffer of several million coins to work (In case you didn't read, I plan to set up a transaction anonymization service that 1) has buffer in the millions 2) can operate without a website)

That will make TBX and GG extra-attractive for SR types Cheesy

Also, there is no upper limit on TBX generation, so at some point in the future, the Fun-d won't be all that big compared to the whole system

Doesn't seem to bother people with bitcoin.
Admittedly that's a rather lower number, but still.

Doesn't seem to bother people with diamonds, gold, and USD (and the latter can be printed at a whim as well)

Meh, botmasters will have  incentive to hoard anything that they don't need to spend on their immediate human needs (hookers and blow) and botnet's expansion (buying 0day exploit  know-hows etc.)

Which means that botnets will increase price (slowly, at first)

And the higher the price escalates the more incentive rational botmaster will have to hoard.

Who is here in the same boat; and has gpus; and knows that the solidcoin 2.0 version will be gpu hostile;

If you are in the same boat; come with me and say fu to solidcoin; and mine i0coin.

Y not mine Geist Geld ? It's GPU friendly and has 15s blocks and Escrow transactions (and might soon get other funnehs)

Meanwhile, if you want to mine a CPU-friendly cryptocurrency while mining a GPU-friendly cryptocurrency you can mine Tenebrix

P.S.:
Full disclosure - both are currencies I am strongly associated with and allchains.info sez that NMC is by far the most lucrative GPU currency to mine.

285  Alternate cryptocurrencies / Altcoin Discussion / Re: I0coin starting to come back on: October 05, 2011, 10:45:51 PM
Solidcoin is for now largely an imagination-friendly currency. That is, you can only mine it with your imagination.

Sadly, it can thus be exchanged only for imaginary assets.

I wonder who did the miniscule buys at the heights to make it look like it was going up? Tongue
Coz obviously it was done that way on purpose.

Probably some of the folks from the speculation subforum

I wonder if ixcoin author is gonna try resuscitating his little baby tho....

He's already dumped his holdings... why would he continue it?

He continued it quite for some time, I dunno why he did. Even now he occasionally pops up.

I wonder if ixcoin author is gonna try resuscitating his little baby tho....
So doing a find/replace now makes one an author?  Hmm, maybe I should start publishing some works based on Harry Potter novels Smiley

An obnoxious Russian woman has beaten you to it by about two years or so.

I just got like 10 proofs of work (including one for 10 trillion TBX) trying to port this directly to another linux box... beeeee careful when you make the binaries lolcust.

Um, you mean you just copypasted the binaries built on one linux block to another lin and it misbehaved ? Or is something more sinister afoot ?

Also, AFAIK the max coinage a chain can deal with is around 130 billions....

Hmmm... yous got me curious about max coin....  wonder what happens when that gets reached.  Alright lolcust, here might be a fun testnet test for you, start up a testnet with just a smidge less than the max pre-mined and let us know what happens :-D

I think I will, when I sort out a few things with updating TBX and GG with a bunch of Good Things and fixes, and some other things.

I think clients will just crash

Also, is the limiting factor something like max integer size?  If so the problem should be resolved as computers move from 32 to 64 then to 128 bit word sizes etc.

Yes, exactly, though I'm being told that the problem could be solved even before we move to 128 bit processors, just currently there exists no urgent need for a blockchain with 200+ billion coins in it.

It's not like anyone is starting DollarCoins, with guaranteed USD equivalence ~__^

So, I remade with gcc-4.6.1 and there is no actual performance increase... not sure what is going on exactly.

edit: never mind, had to recompile with CFLAGS="-march=amdfam10 -O3" ./configure
and then with gcc-4.6.1

Now I'm at 3.40kh/s!!  thanks!!

Man you guys are just murdering my stupid 2600K crappy Intel silicon. I want some of the love please !

Poster a few posts back : how did you get 1.66 khash/s per thread on the 2600K !? I only get around 1.15 khash/s per thread on my crappy chip.

Bulanula, are you on win or on Linux ? I'm about to pull an experimental Tenebrix Minerd optimization by ArtForz that is tailored to 64 bit linuxes (completely untested on win)
Can squeeze out up to 30% more.

Dude this is what I am waiting for LOL. This crappy 2600K is wayyy too slow for this high difficulty. I'm on Windows now but I also do Linux etc.

Well, I will do a branch from main Tenebrix-minerd tomorrow (the optimization is too experimental to throw it into the main, IMHO). I'll PM you when it's done.

General advice is to build it on Lin64 since that's where Art was getting good results, it's currently verily experimental so take care.
294  Alternate cryptocurrencies / Altcoin Discussion / Re: Tenebrix Landing-page on: October 05, 2011, 08:11:13 PM
I posted this in the main thread, but it got lost in the slew of cryptography-related posts.

Anyhoovers - I created a proposition for the new front-page of Tenebrix.org. I'd like some suggestions and critique. Here it is:
http://46.253.203.113/tenebrix/

Thanks.

Agreed, you're awesome.

I hope I will not be booed down for issuing a reward for this awesome bit of work ? Cheesy

Warning about NTP means that you are best to restart - most likely, you've merely got a shitty NTP server talking to you (I find the "ntp=0 crowd strikes again" to be somewhat implausible at this point), but better safe than sorry.
297  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANNOUNCE] Tenebrix, a CPU-friendly, GPU-hostile cryptocurrency on: October 05, 2011, 07:55:29 PM
Woof woof  Shocked

Good doggie, now run and sell some of the Tenebrix you've mined, because I hear there's some folks buying those thingies quite eagerly over there on btc-e.
298  Alternate cryptocurrencies / Altcoin Discussion / Re: Fairbrix fiasco on: October 05, 2011, 07:51:22 PM
I am far from being a Real Programmer, but I have a sort of hunch that various "dynamic lockins" (be they timestamp-based or "magical transaction" based) could open a rather large can of net-scale DoS worms.
I don't see how an exchange sending out a signed transaction containing a checkpoint to nodes is any different from a coin creator regularly updating the client with a checkpoint and asking for clients to upgrade. The advantage with the former is it's automatic and nodes upgrade automatically.

From the top of my graphic-designery meatbrains (so likely a very measly attack), let's consider a situation with 2 exchanges (not implausible), one of which is under attacker's influence (knowingly or not).

Exchange 1 "blesses" block No X on "legit" chain

Exchange 2 transmits a blessing for same block number ("X"), but on a chain synthesized by the attacker.

Attacker then "reveals" his blockchain, and it is "longer" (in the "sum of work" sense, of course)

How does system respond ?
299  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANNOUNCE] Tenebrix, a CPU-friendly, GPU-hostile cryptocurrency on: October 05, 2011, 07:40:53 PM
Hmm am I reading comments completely missing the obvious? (yeah that is a question)

If you change the PoW you simply add a "2nd PoW" and the code uses the old before Block X and the new starting from Block X

You release an updated everything (daemon, pool, miner, whatever else you like) and set Block X some time in the near future and tell everyone to upgrade before Block X (i.e. some "reasonable" time for them to upgrade)

I seriously hope I am misunderstanding the discussion, coz that would imply people not understanding what they are doing yet "running" the show ...
(relating to a comment I made elsewhere ...)

First, thank you for the remark - while I am aware of how and why upgrades are  implemented at "Block X", your pedantic reminders are appreciated anyway (Since I am far from being a shining example of skill, having someone pedantic around is very important)

However, the issue brought up by MoonShadow was not "how does one implement a PoW upgrade" but "what if a group of people with a significant fraction of network computational power  willfully refuse to upgrade their software with a new version that includes a "chain-breaking" update"

To which my humble response is, basically, "as long as they don't have pools and / or exchanges among them, that is not an issue".

Also, to address an issue I find mildly bothersome, I am not a "showrunner" or "leader", and am a little bit annoyed when people make such claims.

What fantasy land is that () comment based on?

You want to say that alt-coins, or, for that matter, bitcoin itself, has a lot of goods/services providers whose business model is not reliant upon ability to convert cryptocoins to fiat, and are essentially "cryptocoin self-contained" ?

Well, since I am not aware of independent research as to the subject, I might very well be wrong and such enterprises might very well be common, but so far I fail to recall even one...would you please dispel my ignorance ?

How blind can you be not to see that lolcust = artforz = bitcoinexpress !!!

Tenebrix could have EASILY been attacked in the start ( not so much now ) BUT nobody did attack it because they have interest not to attack.

SC2 will be attacked because it is better competitor CPU only chain etc.

Not rocket science !

So, typing dog  standard of evidence strikes again ?

Congrats, you now have 1/7000000th the coins of lolcust.

Congrats indeed.

Too bad the Coin King doesn't share his racket fund with his subjects so willingly Wink
