The difficulty was just in the single digits and now it's up to 13k.

http://www.cryptocoinexplorer.com:3750/chain/Terracoin (http://www.cryptocoinexplorer.com:3750/chain/Terracoin)

And the value of one block was 215?

a big miner stopped trc solo mining and has started again

yes, because there are transactions in it.

the new trc-algo seems to me more or less stable...

What's the new trc difficulty algo?

Terracoin is terrifying  ;D

i got my coins stuck in transit for 48 hours.  27 bitcoins of TRC worth.

I watched the price plummet from .014 to .0025 and could do nothing

hahaa.  it sucked.  what's the scoop is terra gnna pay me back?

The difficulty has gone from 13k to 1 then up to 23k in the past 30 minutes. Is that normal?

yeah terracoin does that now, it has a difficulty readjustment algorhythm in place for high hashrate machines attacking it.  such as asics.  so if those macines attack, instead of it going out of service for 48 hours, it now divides its difficulty exponentially every 10 minutes it hasn't found a block..

that's the cause of the wild swings

Won't that just cause a shitload of stales and orphans?

beats me

I thought that's the reason Coinotron close down the TRC pool, pretty much all the blocks found by the pool was invalid.  Furthermore, the person who is attacking the TRC chain for days now, is still using the time-travelling exploit via really high hashrate, hashing 30 blocks in secret and then dump them all at once every hour (the dump used to be every 15~30 minutes).

Yeah exactly. The chain is constantly being 51% attacked,bit hard to conduct business in it.

seriously there has to be a better alogrithim to use i suggested 2nd or 3rd order exponential smoothing

From what I understand- the chain is being attacked by someone who, most likely, just doesn't give a crap and likes to mess other peoples work up.

There are already now multiple Terracoin fork chains in existence, and it's quite possible that the chain has already been rewritten by the attacker who at times has had far more then 51% of the hash rate of the chain. Most likely the attacker is just either rewriting the chain, or plundering the chain by generating crazy numbers of block to make TRC to sell for BTC at the exchanges. We are being screwed.

There is another mandatory update out, which I would like to think will fix the problem, but at this point, we've been through a number of mandatory updates and the problem just gets worse.

A coin like this really should be removed from the exchanges. I was just about to buy some at BTC-e, glad I read this post first.

This seems correct

Though I can confirm now that it seem Vircurex and BTCe appear to be on the same blockchain as TRC was able to be sent between them

NOTE THIS DOES NOT MEAN AN ATTACK MAY FORK IN THE FUTURE

BUT THE OWNER OF THE ADDRESS TO WHOM YOU SENT THE TRC can always get the TRC BACK FROM ANY BLOCKCHAIN USING THERE PRIVATE KEY FOR THAT ADDRESS

Presumably this is a fate that all smaller currencies that use SHA256 can suffer.

I have a theory that some are trying to undermine all the Alt-Currencies in a variety of ways not just by misusing their ASICs however with some weilding massive power with asics those using SHA256 are especially vulnerable.

Not good.

I disagree PPCoin is SHA256 and as far as I am aware it's impossible to 51% attack computationally because PPCoin relies upon proof of stake not just proof of work. So if an ASIC gets >51% of the hash rate they can't screw anything up. So that is the major threat averted.

Additionally if an ASIC jumps on and ramps up the difficulty and then goes off, PPCoin has it's intelligent difficulty adjustment scheme which has been coping admirably with such events.

It figures I spent the last few late nights setting up a TRC pool, just to see if I could (using a bitcoin pool backend with terracoind instead, need to roll my own front end). Used it as a test all last night, found 11 coins, but only 4 survived. The other 7 I think probably happened during the difficulty dips where coins are found every few seconds. Mine didn't win the race I guess. I thought TRC had gotten stable the other day right before Coinotron suspended. Guess not. :/

Any moment now I expect to see LukeJr rear his head and claim credit for this  ;D


It must be true otherwise it would have been destroyed by LukeJr already  ;D ;D ;D

One day, people will realize that RuCoin is the only crypto with REAL 51% protection built into the client/network and people will use RuCoin not only or the protection against 51% but because it has the nicest GUI/features out of all the clients with btc-e chat/trade built into the client, it's own separate chat system built into the client, miner ID cells which broadcast your miner ID/name to the network when you find a block (people love to have their ego stroked).

RuCoin is best coin.

51 % are not what alt-coins need to worry about.

Difficulty attacks are the real concern.

I just wrote a longer post on it here:

Between blocks 104292 and 104326, one hour of 5.25K diff.
What happened, Asic broke?

It's interesting to note now that 51% attacks are not the only threat, but that difficulty attacks are just as dangerous to a chain.

It seems like from

http://www.cryptocoinexplorer.com:3750/chain/Terracoin?count=20

and the last few pages, that 5255 is the new floor minimum difficulty. Which is better than the swings down to <100 and coins ever few seconds. :)

Perhaps TRC will pull through all of this and I'll launch a TRC pool after all!

So the Terracoin development team is located in East Coast, United States?

I got into Terracoin at the start of this year to learn about the cryptocurrency network.  BTC is just too valuable to waste on test and experiment.  Believe me, I have learned so much thru TRC (including the current debacle) than I ever will via BTC.  Plus, the few active member such as Crazy Rabbit, Fuzzy Bear, and Walter Rothbard all seemed really nice (note the fuzzy animals and puppets in these user names).  So it is a real shame that TRC has come to this.  

I really don't understand why someone with 500 Giga to 1 Tera hash/second hashrate would attack the TRC network instead of making a load of money mining BTC.  Note that this attack has gone on for many days now, while BTC has gone all the way to USD$250 and beyond.  So instead of making up to $5,000 mining BTC everyday, this person is screwing around with the TRC chain and got maybe 50K~60K TRC coins, worth only $10,000 at the current exchange rate.  So the person basically spent $30,000~40,000 in lost opportunity cost to attack the TRC chain.  That frankly is not rational.  

But in any case, best of luck to the TRC team in trying to find the solution.   :)

Something that makes sense is if the individual has a mega ton of Bitcoins from the oldschool days (millions of dollars worth). That person can afford the opportunity cost of not using the ASIC to mine for bitcoins. And that person has an extremely strong incentive to stop competing coins eating into the market share of Bitcoin.

Actually there is a way to test this theory.  Using the latest TRC client, there is "banned IP" list of misbehaving clients suspected of hashing/relaying fake blocks.  Just match these sets of IP addresses to those found on BTC's Blockchain.info and you should see some overlap right away, since obviously 0.5 ~ 1 Tera hash/second hashrate would not just come out of nowhere.  Though obviously some of those on the banned list is likely innocent, since they are just relaying fake blocks from malicious attackers, or they could have been spoofed.

Mining in P2Pool I got on the "banned nodes list" while using the most recent client, mining on the right chain and 2700Mhash/s.

Looks like there are at least 2 chains, when I look in the P2Pool statistics:

http://i146.photobucket.com/albums/r254/MaGNeT76/terra_at_p2pool_zps651ffeff.jpg

dustcoin.com/mining is on block 104396 with difficulty 12265.71592580.  I think I've been on top of updating terracoind from the latest github source, despite the dev's ridiculous lack of communication and short release schedules.

Is it possible that some services, miners and users are just running older versions of terracoin, and the forks are caused by the frequent hardforking updates to the difficulty adjustment algorithm?

https://sourceforge.net/mailarchive/forum.php?thread_name=5168555B.1080905%40gmail.com&forum_name=terracoin-announce shows an email sent yesterday, but that one was indeed quite brutal (24 hours before it becomes mandatory)...

People seeing difficulty below 5255 are on an orphaned chain and should update their client ASAP (this is the minimum difficulty supported by the latest client).

Maybe the TRC devs might be interested in checking out an idea I had: https://bitcointalk.org/index.php?topic=175858.0

Can anyone explain this?

I stopped mining TRC 3 hours ago (P2Pool) but 23 minutes ago my client suddenly said "incoming!":

p2pool always worked like that, PPLNS, you gather shares while mining, then every single block solved by p2pool will include you in payouts as long as you have valid shares in p2pool share chain (that number will decrease with others mining after you stopped)

You stopped mining but the blocks you contributed hashing power to are just now confirming and p2pool is paying you out appropriately as it should.

It's perfectly normal. P2Pool uses the PPLNS reward system.

Your contribution during a time window is used to compute your reward. I don't know the window used for Terracoin, on Bitcoin P2Pool uses a 24h window or the time needed to produce 3 blocks, whichever is smaller.

You don't have to mine or even run your node to be rewarded if P2Pool finds a block.

by the way i'm not sure p2pool is the best way to mine TRC now, i remember an issue (now vanished in limbo) where dev said he was contacting p2pool dev about unusual orphan blocks, and per-block retargets

The client doesn't dictate what the coin is. It's a shit coin and not open source, you couldn't even find the latest source code for. Enough with your RuCoin bullshit. Nobody gives a fuck about the coin, it was so shitty that BTC-e took it out. Come on, stop being so stubborn and accept that it's a piece of shit.

As for TRC... yeah... It's dead. I think it would be best not to mine on this chain before people start losing money.

LOL, like anyone cares what you think Simran... I remember when teenagers used to respect their elders, shame the majority of you are fucking idiots now.

Windows, Java, Flash, many major softwares are closed-source and yet they exist on pretty much every computer in the world without issue.

RuCoin has been around for a couple years now, I've been mining it for over 6 months and I have never had a problem with it not being open-sourced and have had no emptying of my wallets, corruption of my other clients, virus infections, etc...

Do some real research on the coin and go through the forums and you will find that no one else has had any of these problems either in the couple of years that RUC has been around now.

The reason their code is closed-source for the time being is for security reasons, they are not finished doing dev on the client (it is considered to be in Beta right now) and they will not release the current source until they are confident that they have covered all possible exploits.

You can talk all the shit you want about it, but the fact remains it is currently the only client safe from most types of attacks including the dreaded 51%

If you want to keep mining on clients which are susceptible to attack and total destruction should someone have the whim to, be my guest.

But in my personal opinion, having observed you here in the forums and on BTC-e chat, your thoughts and opinions aren't even worthy of mention since most of it is ego-driven, troll-bait bullshit.

So, as I said, the blocks he contributed shares too (be they new blocks, old blocks or whatever) are just now confirming and he is being paid appropriately by p2pool as he should be...

As for the rest of the quote, I didn't bother reading your bullshit.

Respect their elders? I’ma worry about me, give a fuck about you. Besides, you've fucked up your life already, have kids with loads of girls but you're not even there for the kids or the girls...

Yes, pretend to know me and my circumstances...

First, having two daughters is hardly having "kids with loads of girls".

Second, I am not there for my children financially because I am unable to be there for them financially seeing as how I lack actual finances to be there for them with.

You don't know me as well as you might think you do (and certainly not as well as I know you, Simran Singh).

I recommend you keep my personal life out of our discussion as it is really irrelevant to the world of crypto-currencies and certainly irrelevant to the specific topic at hand.

Some pools require the full 120 confirmations, yes... But isn't p2pool what we are currently discussing...?

I reject your recommendation. Oh sheeeeeit! You know my last name!!!!! Because Singh isn't a common for a person named Simran LOL. Good job detective! Add me on Facebook, Twitter, or Google+ :D Oh wait, I don't give a shit about you or your opinion, you poor simpleton.

There's plenty more I could share...

You know, in my opinion, it's likely this guy who is taking advantage of Terracoin's diff is Luke-jr, he's done it before on other alt-coins, no reason he can't spare 100gh/s to do it again.

Doesn't matter who's doing it, this time it's Luke-jr or Luke-sr and next time it's someone we don't know.

Fact is: it is possible to do and with more ASIC's coming attacks like these won't go away.

To gain trust in the coin (by people, pools and exchanges) TerraCoin must be safe against any attack. If not? Nobody will remember it in 2014...

Part of the damage is already done. Remember, the end goal for a cryptocurrency is to be actually used for services and goods from vendors. Recent events do not inspire confidence in the currency.

Vircurex appears to be ahead of my local terracoind and cryptocoinexplorer.com.
Vircurex Blocks: 104530
My Blocks: 104508

TRC deposit to Vircurex is not showing up, probably due to this.

Vircurex is probably on the orphaned chain. I'm at 104508 too with latest git code.

A sizable hashpower from P2Pool is on the orphaned chain too (with blocks >104508).

Or is something else wrong?

People with a lot of coins manipulate the price higher by simulating demand, the people inflating the price sell the worthless coins at well below the current ask- buys get eaten, some noobs buy on the dip expecting a rebound, rinse and repeat.

LOL Good job finding my XDA-Developers account xD!!!!!!! Wrong DoB too!

If you want my info, just ask! I was born in '96, bitch ass nigga.

stfu

Agreed. No one cares who has the bigger internet dick.

That's what the "ignore" button is for. :)

I just now saw this, and I wanted to thank you for your kind words, and add that I feel the same way about the other people who have been visibly involved here in Terracoin.  crazy_rabbit in particular has been an all around great guy and also great person to learn from.

I'm sorry to say I sold most of my Terracoin a few days ago when Rabbit warned everybody to take their TRC out of Terrawallet.  I've bought a few since then for playing around with, but not many.

I hope the network can recover.  TRC was the first altcoin I ever owned, and I learned a TON!  So I hope the devs hear that I greatly appreciate the work they put in and what I learned from the network they created and the economy surrounding it, and the actors in that economy.

I still say, thumbs up for Thumbs Up Guy!  I hope he comes back soon, and I hope that somewhere down the road the forked chains are orphaned and forgotten and things look stable again.  I'm still amazed at the resiliency of TRC's price on the exchanges at this moment in time.  I definitely will not rule out buying more at some point.

And on that note, a comment to the Terracoin devs:

What you said in the Genesis Block is beautiful, and I hope Stephanie is remembered in perpetuity.

Edit:
What's with the birth control goggles son...?

I still win. LOL! Enjoy using shitty dating websites!!!!! xD

Son? I would never want you as a parent! Go mine shit RuCoin!

Keep telling yourself that you beta fag.


A beta fag such as yourself would definitely recognize a shitty dating site when he sees one. Lord knows you probably have enough accounts on enough sites with fake profiles to hide that ugly ass beta fag face behind.


Thank God because I'd be very disappointed that my son turned out to be such a beta fag.


Happily.

You use "fag" a lot, are you a fag? I'm 16, I have no reason to be on dating sites, but it's instantly obvious the one's you're on are indeed shitty judging by the MySpace + Shit look. Me having accounts with fake faces? I'm not BitcoinEXpress and I obviously have YouTube videos, Google+, Facebook and Twitter to disprove your assumption(and of course, you posted my info, take a lot at them, none with fake faces). Your son? Oh so now you have 2 daughters and 1 son that you fail to see? What a terrible parent you are, indeed. You're a dipshit LOL!

ok that's pretty funny

edit: can we get back to terracoin, you're guy's war is sort of getting entertaining, but jesus man

so trc is like the last girl I dated briefly, sending mixed signals. 

"i wanna do it in the backseat"

"I want to go home"

"I'm going to slit my wrists"

"my brother had sex with  me growing up and I have a crush on my dad"

"april fools I'm totally sane and just have an amazing sense of humor gotcha"

"you wish, I just downed a whole bottle of sleeping pills" 

"sike" 

"double sike"

"I'm horny and I like you" 

"sike"

"I'm toying with your emotions"

"take me home right now and don't you dare touch me"

"kiss me"

"I'm calling 911, police I am with a man who hit me"

"just kidding I wouldn't do that to you honey, now let's get freaky"

what is it TRC?  you are the most moody woman I've ever heard of.  you either belong in a mental ward or you need to be elected as vice president under bitcoin, I haven't quite put my finger on it.

what does it mean when it mines a future block early?  is that ok?  is terracoin more or less functional?  is it possibly an ok investment now?  I need signals interpreted from my friends.

oh yeah and crazy rabbit is cool in space goats book, i believe we are all on the same team.

http://www.reddit.com/r/Terracoin/comments/1c9r2h/banned_from_btce_for_mentioning_terracoin_problem/

check this out.

they banned me as well. 

i hardly even say anything in that box.  I said one thing, "trc is going haywire, finding 10 blocks a minute.  that's going to flood the market with coins and drive the price down" 

that's all I said.  banned for 7 days.  is that spam?  I don't even know what spam is

Vircurex is in 0.1.3-33, Btc-e in the older...

Agreed the trollbox on that site is worthless. Everyone can say Arise Chikun or whatever the hell it is they say over and over again,  but the second anyone actually says something useful they get banned

How can we tell which version BTC-E is running? The transfer I made to them this morning (>150 blocks ago) has never shown up. They said there are problems with the TRC network and to give it time. I'm suspecting they aren't running .33 though and are on the wrong block chain somehow? If so, I wonder what that means for all the buyers/sellers of TRC there currently.

I mined about 10 block without realizing that I was on a forked chain... That morning my transfer from forked chain appeared on BTC-E with no problems at all. Later I updated and lost 60 coins.

Unless you  have coins that you have MINED on the fork, you will lose nothing.

Except for coin base (mined) coins,any transactions on a fork are not on the real chain. Therefore you may have to use a backup of your wallet, or use PYwallet to remove the transactions from your current wallet so the client can rebuild the transactions from the correct chain. (Your client will see the coins you sent on the forked chained as spent until you do so)

I emailed BTC-E to see if I can get an official response on what version of terracoind they are running. The coins I sent off were coins I mined myself, and are in the official block chain. I think what's happening is BTC-E doesn't see them because they aren't on the right chain.

I just had a deposit go through on BTC-E that I sent this morning that was also MIA. It looks like they have corrected their issue.

Still ok with the original wallet, don't need to upgrade or anything?

Yes, minutes after posting my transaction finally popped into my account. :)

Client YES

Wallet nope, if your wallet needs updating with a newer client , the client will auto update it.

If you have transactions on a forked chain, it gets a bit trickier, but it is much easier if one keeps backups of their wallet like everybody does....RIGHT???... ;D

Glad to see Coinotron resumed TRC pool. :-*

lol, well never actually used it so no issue in getting a new one. it's stuck it seems updating blocks.

WTF?

http://s1.directupload.net/images/130510/gl3ydhz6.png

Despite the fluctuating difficulty, TRC has been topping the mining profitability charts often this week, enough to make me have another look at it. Found a nice little pool to use.  http://terracoin.redpoint.ro only 1% donation which appealed to me over the 4% others are asking.
