Information on attacks
-
Just woke up, see a lot has going on this night.
We are just getting popular :)

“Community is popular” :)

Hi guys,
are the attacks still happening? I’m having a lot of trouble connecting to my regular pool.

[/quote]Which one is that? I mine on Coinotron and ther site is down whole day…

D2 pool. the pool operator is doing his best to resolve the issue (as I’m sure all pool operators are). I guess we just have to sit tight for the moment. -
A lot of transactions suddenly went to unconfirmed. Hope I won’t lose those FTCs.
-
I think the 51% attack is still going on. My pool (fcpool.com) generates nothing but Orphans. I lost a whole day’s worth of mining! I’m switching to another coin…
-
Take a look at the block chain.
http://explorer.feathercoin.com/chain/Feathercoin?count=500&hi=33711
All the blocks timed at 18:XX are generated by the attacker. Every so often they orphan genuine blocks and they seem to be trying to orphan them all. This is an attack on all the pools as any blocks found by a pool will be orphaned.
Pools should disable PPS if they are running it and move to RBPPS or something similar.
This seems to be a reaction to the large investments we saw in the Feathercoin markets yesterday. Last time we suffered from these attacks it also coincided with the price rising.

hmm…check this out…

D2 pool seems to be stable at the moments, might be of help to you if your pool is still down. -

[/quote]How do you think they are able to achieve this? Is there anything we can do to actively help prevent it? Other than mining?

[/quote]A classic 51% attack with repeated block chain forks and DDoS on large pools. Our hash rate is too low to prevent such attacks. Need to grow up again.

[/quote]Zerodrama is working on technical solutions, he seems to have something that would make this type of attack much most costly to achieve. The world is a dangerous place now that all those GPUs have been freed from Bitcoin mining.
Such a solution is a long way off so in the mean time let’s get mining. I have a new mining rig to build to put into the mix :)

By the way: Who’s finding our blocks?
Coinotron is down, and all the other pools I’ve checked only find orphans.
So who’s finding “legit” blocks?

[/quote]The attacker is finding the block and orphaning our blocks as they have more than 51% of the hash power.
Wemineftc seems to be down to.

[/quote]Do you know the current hashing power of the attacker?
What are we miners supposed to do now? Solo mine?

have solomining as failover. that way a ddos attack on the pool wont affect the network hashrate since cgminer goes solo mining when it can not reach your pool -

[/quote]fcpool has had more than 50% of hash power for a day. one user with 159MH right now. It’s been working though they got a lot of orphans and now have a bunch more found blocks at 360MH for the entire pool.
-
612,268,522 KHash/s (60 block avg.) now and all the blocks being mined are orphaned again… :(
-
WOW
Current Network Hashrate: [b]612,268,522 KHash/s[/b]
An hour ago give-me-ftc was at [b]70%[/b] network hashrate @ 470 MH/s
Currently give-me-ftc is reading [b]Pool: 468.14 MH/s (0.1%)[/b]
-
Now it is back down to [b]197,750 KHash/s [/b]!
The attackers must be increasing hashing power to about 99% certainty to solve blocks & successfully attack.
This attack is not to destroy FTC but to make a lot of money it seems like.
