Topic: TERRACOIN ATTACK OVER 1.2TH ATTACK CONFIRMD - page 7. (Read 28159 times)

You don't see evidence of timewarp attack? You'd better look more clearly at blockchain.

Hence merged mining... no hopping needed, just mine all of them at once.

-MarkM-

you guys realise chain hopping has been happening since before NMC was merge mined with BTC? I am sure some of you have done it yourselves (actually people in this thread have admitted to it)- so this guy has lots more hashpower than you? ....bummer
ASIC were always going to screw up sha-256 alt coins - this is no surprise.Miners were working out which alt coins would be viable to mine ASICs on before deliveries even started.

I don't see evidence of an attack, just a miner doing what many others have been for years, what makes him unusual is the size of the hashrate - don't worry there will be more and more like him as more ASIC devices get delivered.

I wonder what happens when #175000 is reached. Attacker seems to have a lot of power.
How long is the sampling interval for difficulty changes?

Thanks for posting this update link!

This is a very clear explanation, thanks.

I'm partly inclined to agree with the above.

Also correlation does not prove this entity's guilt. What happened to innocent until proven guilty?

The attacker mined at max using 3600 power solo mining TRC...The total network TRC has been 4200 giga ( 500 was on Coinotron) or so for few time before to back to 1200. When attack stopped, 3 minutes later ozcoin got a anonymous miner havong exactly same power around 3600 giga. This new ozco miner dissapearead after few hours. And the attack restarted in matter of minute on TRC

99.99% sure then yes still 0.01% for coincidence. Sure can be lot of people behind, we all have friends having 3600 giga power those days...

111k just sent to same address on block 171932:

I cant believe that no one has already found his IP. There should be a proper hunt for this guy. I don't agree that its not wrong to attack a coin. What makes you think that its fine to steal? just because you know how and have huge hash power? what a bollox..   If your bank account was wiped clear by a hacker, would you say its nothing wrong with that? because the guy knows how to do it and has processing power to make it happen?

Can't trust those balance figures though. Heck, this single block he's moving around 290K coins:

Updates after looking around seems theri aware of it new updated client.

Terracoin update 0.1.3-42 is now available for download at our
sourceforge mirror and github repository.

This build addresses the difficulty manipulation issue currently seen on
the live chain, and will be mandatory on block 175000.

The code allowing such difficulty manipulations was added to the client
prior to the ema difficulty adjustment implementation, it should have
been removed from the client long ago to prevent this.

Once most network nodes are updated, and block 175000 is reached, the
capped ema implementation should take care of abnormally forged blocks ;
as usual, this is supposing the network gets more hashing power than the
attacker(s).

With the current artificially decreased difficulty, and the network
hashing power way higher than the 'awaited' rate, network will generate
a lot of orphan blocks until this issue is addressed.

1 I have checked all pools and theirs no one or even a pool close to that power.

2 Looks more of solo mining and or they have a private pool setup exploiting all others.

3 if wanted providing their is blockchain that gives the info like blockchain.info you will find location of where he or she or group is mining coins from.

TRC address of coins going to 1PAnMKuTs9R4U9FF7xdQSmQc655d2r9zeB

Transactions in: 379
Received: 7580 TRC
Transactions out: 0

I was happily mining away over at multipool when I seen orphaned  and then I seen the difficulty go really low then went back up then down and all over the place. I thought ok must be a few blocks bad then more was like ok whats going on no word in irc no details then decided on posting and seeing what has gone on. I hope that TRC devs are working to fix this and the only solution tho it seems would be a hard fork to the date before this happened.

Well that's a point of view.

Another example : someone hack your own bank with a weakness in your computer. Theft your saving. Then you will have same point of view about exploid of weakness in your computer? Or so I could say as you : dont let in your bank account what you can afford to lose?

Point of views are different according what we own or not in a quoted situation. I agree with you about that.

Ah, I just love Terracoin summer sales.

You gotta be kidding right? You want a pool to give out the IP of someone who might have done the attack, so you can harass him?

First you need to start by realizing that it is not even wrong to attack a coin. If there is a weakness that can be exploited everyone that wants to spend the energy and hashes is free to do so. That is the problem with most of these alts, they are not secure enough so dont keep money in them that you cannot afford to lose.

Do you know his username of forum Im going to request him his opinion about. Cause 100% at least 99.99% it s our attacker

I mysef was minning on cointron with 2 avalons TRC and changing for osco when i mine BTC. I also noticed the game...behind on both site when attacker playing...stoping restating...

I hope they give out his IP.

At the worst moment of attack : Power of attacker was not 1200 giga but like 3600 giga power (like 60 avalons power)

Does there are 10 people with such amount of asic or hashrate power? I dont think... then the attacker is easy to find lol...

We have a smart attacker changing timestamp and all ( smart attack, the attacker know what hes doing with algo), but stupid enought to mine with 3600 giga showing it can be only few people behind...

Notice : when attack stop, ozco.in get 3600 giga hashrate more (1 anonymous user with 3600 giga LOL), So we can assume this miner is our attacker. Hes actually no mining on ozco since attack restarted but just wait it stop and see again + 3600 giga ( one user) coming on ozco...

Maybe ozco.in can report his IP so some can have some fun too...

At current exchange rate the network would need to be more than 20 PH/s before even the least efficient ASICs are unable to operate profitably (note once purchased the capital cost is sunk so we are looking only at ongoing electrical cost).  It is more like 40PH/s for BFL and KNC devices and 80 PH/s for Bitfury.   With the network currently at 0.2 PH it would take a massive amount hashing power (and thus capital) to push the network rate that high. 

No matter how efficient Bitfury are sales will slow once the ROI% on new hardware is pushed low enough and that should happen long before the least efficient EXISTING units become unprofitable.  The one thing which could change this is a significant rise in exchange rate for an extended period of time and then a substantial crash (i.e. exchange rate rises to $500 over next 6 months and then crashed back to $100).
