I'm wondering if bitcoinexpress is involved with the ddos attacks or if this is retaliation against bitcoin pools from SC users?

SC users mine with cpu's unless of course sc has lazors in it....

...and CPUs do a great job at DDoS don't they? I wonder if any Windows software that could have a hidden botnet has been introduced recently?



It could explain the drop in hashrate experienced by everyone. The missing power could charge a loic.

I highly doubt this scenario.

No, I don't really think so either. But then again, it's not something I would put past CH/RS. He does seem to have something against Deepbit in particular.

Not quite—  You generate a normal block, then use your trust account to mine a trusted block right after it (especially easy since it's a minimal difficulty computation).  If someone else had beat you to the punch on the normal block it doesn't matter— the chain with the trusted block is the longest one.  So while the trusted block itself costs you coins it gives you a veto over the identity of the generator of the prior block.

I was wonder about this too. I asked CH in an earlier post but I think that section of the post got derailed.

I seems implausible that they would go to all the trouble of adding in interleaving blocks (What I called a vector clock) without realizing they could be used in fork detection. Basically this would supplement or override "the longest chain" rule in cases where a long fork appears out of the blue. Otherwise, anyone who could isolate a single trusted peer could run wild.

However, I didn't think it was plausible to invent ten 1.2 MSC accounts to make interleave feature work either.


From what CH/RS said, it's not the longest chain but the richest trusted node. So I guess if someone manages to grab more coin than anyone else they'll be in charge?

Is it possible that the solution to "GPU Hostile" crypto-currencies lies within the IE9 Hardware Acceleration and an older lesser known work around for previous anti-parallel computing by the cryptocommunity?

Maybe a modded hardware accelerator could turn GPU's into APU hybrids and could crunch at tens of thousands times faster than every CPU on the network combined. A mere 1 GH /s machine would be a beast...I would shutter to think what a 68 GH /s farm would do.

I would love to claim this as my own idea but it in fact is the (theoretical) brain child of a couple of iOS engineers I know. They (theoretically) adapted it from from previous failed attempts at cryptographers to prevent parallel computing in cracking MD5 hashes.  "GPU Hostility" was solved a while back.

I would also speculate that someone needed a testnet and really didn't want to disrupt Tenebrix as there is already an exchange and pool. I would venture to say this theoretical attacker may in fact have nothing against Fairbrix and is developing a Solidcoin killer.

All just theory on my part.  Grin Grin Grin

~BCX~


PS I would also guess the test is complete and I wouldn't worry about it.


And that, theoretically, would be fscking hilarious. One would hope that this theory would be published at some point, after the testing is done, of course.

The pchar message headers were changes AND a new genesis block was created. So there's no way that the old fairbrix client was the culprit. It is possible that this chain reorg was accidental, but not likely. Anyways, it seems like the overall network hashrate has grown and it's harder to pull off this attack now. And given that fairbrix has no value right now, it's not really worth it to keep attacking it.

Then it was never worth it to attack it in the first place. Why would anyone pursue such an attack when there's no exchange? The only reason I can think that anyone might want to attack it would be in preparation for attacking tenebrix, which you can exchange. Maybe some of the RS/CH sycophants were a little worried Smiley

Still, I'd be willing to bet that it comes down to an accidental fork. Has anyone done any real investigation of this yet?

I expect a better release, under a new name to come.  It will be properly tested and released to thwart potential attackers.  Stay tuned.

I wouldn't do that until you know what happened. I expect you'll find that it was a result of old & new clients working the same chain. If you reboot it yet again I doubt many will both with it.

Here is a "for dummies" product I plan to introduce soon.

I am working on a non-denominated gold-plated bearer bar that looks expensive but isn't.  On it is a hologram with embedded private key.  The bar comes with 0 BTC and the hologram explicitly says "zero BTC" on it.  But there's an address on it and a space where you can put (engrave, or sticker) your own denomination.

Someone who wants to save BTC can send their BTC to the bar and stick it in their safe.

The whole point of the bar is that it looks valuable.  Someone's heirs will treat it as such, and will probably store it or look for a way to sell it to somebody, exactly as if it were gold.  On the other hand, a flash drive in an envelope with a bunch of instructions about "TrueCrypt" and "PGP" will, in my opinion, probably get disregarded as not worth the trouble by most non-technical people (your mileage may vary - everyone's family is different).

On the other hand, while you are still alive, it's cool and novel to have a safe full of bitcoins - that looks like a safe full of gold bullion.

I would buy this.

720 is the current block per my client.
No blocks since the first maybe 150 or so actually have coins in them as far as I can tell.


May have been a good idea to premine further after all!  There's some irony for you.

EDIT:
Sidenote:  The client (not the miner!) is eating a tremendous amount of CPU power on linux, is there a miner built in or something?  When I say tremendous, I mean literally every cycle it can get it's hands on.

Hmm. Maybe having a dev fund is a good idea after all...

10  Alternate cryptocurrencies / Altcoin Discussion / Re: [ANNOUNCEMENT] Tenebrix needs Bounty Fund Directors...Who would that be? on: September 30, 2011, 07:32:15 PM

I'd recommend yourself, ArtForz and any/all Exchange and Pool operators.

He doesn't know whats wrong because he can't code and doesn't understand any of the errors. It's hilarious.

As far as I've seen, Lol-y hasn't ever said he was a programmer. Quite the opposite in fact.

That's probably why part of the 'fun-d' is set aside for paying coders.

i've changed my mind on this, it's not 1 guy with 7million coins, it's a currency with an equivilent 3 year money supply for a laundry to facilitate anonymous transactions (one of bitcoins possible weaknesses).  If this laundry is used as a laundry it will actually add value to the currency, and i've become convinced Locust is serious about this laundry, well convinced enough to gamble what i've mined so far on it.  

That said I would still like to see a faucet with 1-2mil in it for non early adaopters, distributing it to the early miners seems entirely pointless to me(and i'm an early miner).

That was before you were forced to admit that you had premined 7.7 million coins for your money laundering operation. Once I found out about that I wiped the usb key containing GG and chucked it in a river.

Destroying evidence (and then admitting to it on a public forum)? Regardless of how any theoretical trial turned out, that could get YOU sent away.

I had this error when I want to compile GG on Linuxcoin, anyone know how to resolve?

make: wx-config: Command not found
g++ -c -O2 -Wno-invalid-offsetof -Wformat -g -D__WXDEBUG__ -DNOPCH -DFOURWAYSSE2 -DUSE_SSL  -DGUI -o obj/auxpow.o auxpow.cpp
In file included from auxpow.cpp:4:0:
headers.h:30:19: fatal error: wx/wx.h: No such file or directory

make: *** [obj/auxpow.o] Error 1


It looks like you need to install the wxwidget-dev package.

First bounty: Update Notifier

One of the things Geist Geld desperately needs to avert various unfavorable experiences down the line is a means to somewhat meticulously and insistently (within reason) notify the user if the majority of peers he is connected to have a version different from his own.

This will help to draw the user's attention to the fact that his version is lagging behind the general Geist Geld frontier and he'd better catch up until something bad happened.

The bounty on this one is 69 777  Geists, and of course proper credit in the  Contributors section of the website (which gonna go up real soon)

Meanwhile, I would ask the kind community to provide feedback as to possible pitfalls and implementation suggestions.

Thank you very much in advance

Wouldn't it be easier/more reliable to build a check into the client against a file on the website? Then you'd know as soon as you start the client if its out of date or not.

Another nice donation, some more nice pix!  This is the better half at her largest *well, largest for now*!  This is part of her "green top" series.

Enjoy!

Thx, still loving the pix.

Cgminer is working ok for me,  -s 1 -q 0. I've probably spent about 36 hours mining it with a 5830 and I've gotten about 60 blocks I think. Lots and lots of rejects. It took me a while to realize I needed to lower the scantime (duh!) and it seems to have picked up quite a bit since I lowered it.

Couldn't seem to get poclbm to do anything but I didn't mess with it much. It seemed to connect ok and it showed about the right mh/s but nothing ever seemed to actually happen. No accepts or rejects after a hour or so.

The gg client itself seems to be working well enough. Wish I saw more connections though, I'm usually seeing them in the low 20's. I think the highest I've seen is 29. With the .24 bitcoind I normally see over 100. Running Ubuntu 10.10 x64 on a single core AMD.

I did get the time warning message when I first started the client yesterday. As soon as the block count caught up I stopped and restarted the client and I haven't see the warning since.
