The attacker is finding the block and orphaning our blocks as they have more than 51% of the hash power.
[/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 -

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?

Wemineftc seems to be down to.
[/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.
-
Well almost everything I made today jumped back into unconfirmed status for some reason :/
-
We as a community need to focus all hashing power we have and keep as much as we can on mining feathercoins.
-
Our pool stopped FTC for now, since we just lost 2 blocks, one with more then 26 confirms already.
I am investigating the issue, but i cannot run a PPS pool in this situation…
I will bring FTC pool back up as soon as i locked out all PPS workers… so you guys can try to defend the coin… but PPS is not possible at this point.Happy Mining.

EDIT: We are back up, PPS workers are disabled.
-
Use a rbpps system on feathercoin to help encourage people to hash.
-
are the blocks being stolen still able to be cashed out? Cant they be nullified in some way?
-
That will depend on how the FTC network & community handles the situation.
My first idea was the rollback to a certain block, which has not been corrupted and check how many blocks will be lost for the real network(not the fake chain)… if that relation is fine, we might just hardfork the chain ourself from that given point.That would require client code changes i guess… this is serious guys… we need to figure out a solution fast, before the still running pools, loose to much and have to stay on the fake chain.
I am really considering to stop FTC at all, and wait until we do that hard fork, otherwise we confirm the fake / attacks chain…

You can beat the bad chain by more hash not less.
Also there’s ways to fix this mess.
I’ll draw up a strategy.
This is getting ridiculous.
-
It would seem that someone is determined to mine all the blocks for themselves. All blocks mined are being orphaned. The quick fix to beat this is a lot of hash power, with FTC difficulty going down, FTC price doubling, BTC difficulty going up and BTC price going down we are 240% profitable to mine over Bitcoin. This will bring the miners in to the point where the attacks cannot effect us.
The bigger we are the harder we are to attack.
-
attack already has been done… if we try to outrun them now, we will confirm their blocks, if we do not rollback to a certain checkpoint…
I do not like confirming an attackers coins.Hynodeva
-
Roll back.
-
People’s transactions have already gone through those blocks. By rolling back this many blocks we would only do further harm.
-
Rollback is chargeback.
There’s ways to fix this.
But we need to get in a chatroom where we can talk.
-
Man these attacks suck. So are you saying the solution is to do nothing? Is that the option that does the least damage?
Also thanks for the explanation on the 51% attack. It makes alot more sense to me now.
-
Well if it was a botnet, would it be plausible to just disable cpu support? Sorry if I’m talking out my ass, I just want to help…
