\[Bushstar Response Incl\] Fork and 51% the chain of event, including 33000
-
So I was so happy I found block 32,911 then it came back as an orphan… i was pissed. Now your telling me it was intentional.
if your theory is right someone could redirect one of the new alt-alt coins for about an hour and break something. i remember seeing a WDC pool and for abit ryc pool above 400M hash rate… heck the wdc pool was at 966mhashs… it was a few day old pool at that.
What’s the actual solution to something like this? Excuse me if I’m not as informed as others. I treat this as a hobby.

Ignore him he wants even cheaper coins :D
Oh and for the record, I have never changed my mining address, so that’s your FACT out of the window :), I’ll leave bush to explain the rest! 8)
You only joined on the 21st, stating that you are basically an expert in Cryptography/Security ::), my guess is:
You SIR are A FUD merchant! >:(
-
If someone or somegroup is willing to go to all that trouble,
that means only one thing,
they are scared of feathercoin.That fact alone makes me dig in even more, hope they enjoy throwing money at us. :P
-
Any way to track back the source?

I wouldn’t start to panic just yet. :) We know there are groups that would LOVE to see Feathercoin disappear. Bushstar will do the analysis and we’ll make any corrections as needed.
In the meantime, back to work for me.

Don’t panic :)

waiting nervously for bushstar comment.
Is this some of the reason why ftc has dropped like a rock to 0.0009 btc/ftc. sell order of over 2mill ftc
[/quote]I saw that. Someone put huge sell orders on to suppress the price. I bought as many as I could :P
Back to business. Someone is “testing” our chain and this is expected. This is nothing new and is something that all coins have had to suffer. Orphan chains do occur naturally and resolve themselves. WorldCoin with 15 second block targets generates many orphans, apparently it saw a 300+ chain orphan on one pool. An attack of that size would be incredibly hard to sustain and prove costly to the attacker.
I’m not sure what the motives are but perhaps we could piece some information together to investigate what is going on. We already know that they must have around 2.25GH/s to create blocks as fast as they do. This could explain why some complained about confirms resetting to zero, if your transactions end up in an orphaned block they have to be resent in a new block.
I will bring zerodrama into this conversation.

First off this concern isn’t about cheap coins but about breaking something. If you break something someone has to benefit from you using the non-broken thing.
I’m only about a month or so into the crypto-community. i remember jumping around to different mining pools to figure the stuff out and see results. There were so many that had some what high hash rate that I didn’t really anything from. i really learned more about crypto by using an honest stable pool done by BigVern because I could see actual results and attribute it to what people were talking about in many different forums. This makes me go back and literally question those other pools on whether for a day or two they were breaking stuff.
I wouldn’t call this a panic but a reasonable concern. Does this take effort? yes. Stability is FTCs future best friend. This would threaten it or deeply delay it.
-
Quick point to note is that the best way to protect ourselves is to grow bigger. All our efforts on development and adoption will bring value, volume and miners to the coin. The larger the hashrate the harder we are to attack. All coins can suffer from these attacks, but the larger ones have less concern.
Then again Bitcoin could experience this again with the rise of ASICs in the hands of the few.
-
First of all, a 51% attack is actually half of an attack.
51% takes control of the network, you still need to create false transactions, orphan your target chain so it ends, all sorts of other business.
The interesting thing in this thread is the idea of jumping orphan chains. This is interesting because it could be a means of fraud or a means of destroying your own trail (not necessarily a bad thing).
Still, 51% isn’t a death sentence. It just means shields are down, prepare to for pirates, if we’re to use a Star trek metaphor.
-
Groll - should be troll :)
-
Even a few consecutive 51% attacks can be reverted through a hard fork invalidating all blocks mined after a known good one. This is the last resort though.
It would be good to know who attacked our blockchain. If it is a large public LTC pool, then disclosure of this information is going to hurt their reputation badly.
UPD: BTC-e seems to know something. They have increased the number of confirmations for FTC deposits from 5 to 50.
-
You think an LTC pool redirected work toward FTC? (6FeathercoinSucks C T B (btc backwards) seems more of a BTC ONE TRUE COIN tard attack).
-
Could be. I remember the lethal 51% attack on CoiledCoin executed by Luke Jr using Eligius hash power, though it was rather easy due to merged mining with BTC. Need to investigate further.
UPD: Seems we’re still under attack. Someone moves millions of FTC.

That’s all for now, I’m falling asleep.

okay this is someone with a grudge.
i take this as a compliment.
we should give BTC-e a pat on the back for acting even without being asked.
1000x more trustworthy than mtgox.

your probably right about the BTC lover type, but that means he control all the hash power himself as he need to make it scrypt not sha256.
[quote]UPD: BTC-e seems to know something. They have increased the number of confirmations for FTC deposits from 5 to 50.[/quote]
humm that don’t sound good :-[, i was about to ask if their was someone that accept after 5 confirm, this answer it and is exactly the answer i didn’t want to get: BTC-Eso this one is speculation but I think:
he send to BTC-E then revert it. Sell all in BTC-E and then transfer to a BTC wallet before BTC-E can get anything back(if he is not so stupid to keep money at BTC-E will trying to fraud them ;) ). so this can be a 500K$ lost for BTC-E :(I can be wrong on this but I will not bet against that speculation ;)
for 33062 to 33069 their was move of coin. Block mine by he, but only a 33062 orphan as of now without anything very suspicious in my eyes at least. this seems just a i get out as fast as i can (would be a good thing in fact)
or he can try to make a 50 transactions fork :'(edited their is a fork but at 33057. 1M FTC. Back in chain for 33062 was in fact making the orphan. a bit weird
For the one that call me troll or wrong please at least find some argument (BTW: many don’t mean all. my english is not very good but at least i know that :) )

How can someone have this hash power. Any of the top 5 LTC mining pool redirect to FTC can do it, a non listed LTC pool can also have this hash rate. [b]An alt coin with high hype can also do it with pool redirect.[/b] (redirect can be for one or more alt coins pools that use script redirect to the target coins)
[/quote]I have to admit I mined quite a few of the new alt-coins in the last weeks.
New pools spring up like mushrooms these days. No one knows for sure if they are legit or not. And no one cares, as long as they mine the coin of the hour.
Not all of the pools have paid out correctly. I remember a pool (won’t say which one) where I mined for 24h and got only paid a fraction of what I should have got.
So the idea would be:
- Open a pool for the most popular coin.
- Payout correctly for a day or two to build up lots of hashing power.
- Redirect to Feathercoin and screw up the chain
- Users start to complain … let the pool die …

[/quote]Wait what? Luke Jr misused the hashing power of his clients to start a 51% attack? How come he’s not tarred and feathered?

Although BTC-e has acted accordingly to the situation, we have to do something as well. A quick solution is to release a new version of the client with a higher number of confirmations required for transaction. We can also implement some kind of central checkpointing for a while or even proceed further to PoS. If we do nothing, repeated attacks may destabilise the network as many valid transactions get into orphaned blocks.

[/quote]He thought of CLC as of another pump & dump altcoin and punished it in his way. Far not all Eligius miners approved this execution post factum, though he got away easy.

So it looks more like feathercoin is being used rather than attacked, used to make profit from the exchanges.
With the exchanges upping the confirm amount, it will make it harder to sell feathercoin at those exchanges, the price of FTC should establish a more stable base (it will slow down the pump/dump antics).
Its probably being done with other coins also.
