Feathercoin network up 3 % over 2 days- NETWORK ATTACK?
-
Hi Magic Magic - that’s not the attack, he/she injected 7000 ftc worth of false block accepts into the chain. There is a new block every 2 seconds from 9:51:30 to 9:53 this morning. The attack only took a couple of minutes ( I notice) so maybe more economic than you think.

The 2nd fork is at [url=http://explorer.feathercoin.com/block/8daf09be872593b4d1121dac60fde748fd1b31c359061b3ec855f92408296f0c]#51801[/url]. 29 additional blocks orphaned, the total is 63 so far, and it may not be the end.

It’s obvious we’ll need to lead by example with a technical solution. Hopefully the miners realize that ANY scrypt coin outside of LTC can get hit just as hard if not harder and more frequent. With 60+ alts floating around and the promise of LTC Gox, we’re fighting for every single hash.
4 prong approach:
- Bushstar continues with advanced check-pointing
- We get additional community members contributing code to resolve possible attacks
- We increase value through services (starting in a few days) which will attract miners
- We continue to promote
By time we’re ready for wide adoption, we will have already had the experience to deal with different types of attacks.

Yay for attacks, I was getting bored. ;D
Come get sum. Yeah. ;) -

[/quote]I’m almost ready to try a different route to checkpointing.
Reorgs require no effort. I’ve thought of a few ideas, but when you mentioned options trading I had a breakthrough.

Hi Zero Drama, I originally posted the 3% rise in hash as a good thing, but analysis showed the attack. Maybe a separate issue or arising from the difficulty change. The attack is bad, and your information on the wild swings in Hash is bad.
- I had already noticed from my analysis, that some of the swings were due to high hash rate miners like our own Nutnut moving or updating his rigs. Where the swings are due to Feathercoin miners diverging into worldcoin etc… that maybe OK, as they are not attacking the chain with injects.

[/quote]It took a couple of minutes to inject, true - thats the time when they had to surpass the network hash. But they had to mine their longer chain on the current difficulty.

Dont forget its summer and certain people has heat issues=P
My 13Mhash park is going all over the place due to heat. - I had already noticed from my analysis, that some of the swings were due to high hash rate miners like our own Nutnut moving or updating his rigs.

Hi Pyxis, you haven’t got any spare change for stopping your boredom, help finding the attack and my loss of coins (at least 4)??

[/quote]4 coins? Ill transfer em later

Hey, was there a DDos against Litecoin just before the Feathercoin attack? and again at 12:30 and 1:30 - Looks like DDos against P2pool?
Perhaps the DDos reduces pools to make it easier to confirm injects? Or make their solo mining more profitable? with the attack as a diversion.

[/quote]Bad news is good promotion ;) people will talk, out name gets out more.
So the way i look at it, we are buying advertising. ;) -
Pyxis, this is not good advertising.

[/quote]There is no such thing.

Some people see it as Feathercoin is worthy of being attacked or worth attacking. Many coins aren’t doing anything and therefore aren’t worth attacking.

[/quote]Certainly good for upsetting miners. Bit of a viscous circle really. We need more miners to stop the attacks but those that stick around and mine loose coin so stop mining.
Exchanges loose out if they don’t have high enough confirms before deposit so they raise their confirms which annoys people because they have to wait for 500 confirms before they can trade.
Pool ops loose out because they feel they can payout on 10/20/50 confirms then get all the blocks orphaned so they raise them up again.
Long and short - Miners get stuffed. Hardly promotion. :(

[/quote]the purpose of ddos is to take down pools, all the miners on that pool that do not have set failover option in their mining software will then stop hashing.
That way the network hashrate goes down, and it requires less hash to get 51% of the total network.p2pool should be ddos resistant, but if to many attach to the same node it would be popular for the “bad people” to ddos attack that adress, since they will take down a larger piece of hashpower.
EDIT:
just sent you 4ftc -
If it was good advertising the banks would be shouting how much money was defrauded from their cards, Tesco would glory in the horse meat content of their frozen foods and egg farmers would broadcast the level of salmonella in their chickens…
-
We’re splitting hairs here and not moving any closer to resolution.
- Attacking hurts us with confidence in the coin and our hard working miners lose out and security is questioned (1 side)
- Attacks prove that the coin is worth attacking right before the Oxford event and UNOCS announcement (the other side)
Hopefully we’ll be able to get some timelines on the check pointing system fairly quickly. Our time would be better spent testing code on possible future solutions.
