All my miners have dropped off FCPool now, although their website is up. Anyone else having problems with them? Wonder if they’re being DDoSed, as they’ve always been rock stable before for me…
[/quote]Yes mine say slow or invalid users but blocks are being confirmed and paid

Hashrate at 2,2ghash/s
Another attack or just really popular coin? -
With FTC off of Coinchoose (apparently) and/or CC getting DDoS’d that would not be a good thing.
-
Just wondering who are doing all the attacks? Anti-FTC group? seems like they are doing the attack at important change of events (the hard fork@33000) and now the new lower diff.
I am just guessing :
What is the objective of doing the attacks?
to prove or to make a point that the particular currency isn’t safe/stable that it can be attacked, creating a fear and losing trust.
to prevent the particular currency from gaining popular foothold.Who will benefit from the attacks.
- Banks or Government that doesn’t want want a crypto currency.
- other currency holder that only wants their own currency success by trying to kill off others.
(eg, BTC fanboys wants to kill LTC, LTC wants to kill FTC… etc…) - someone who just wants to prove a point… hmm…
for group 1, not likely, they would want to hit the big boys which should be BTC, why hit FTC?
for group 2, very possible, in fighting happens alot of time in history.
for group 3. may also belongs to the group 2, but with a heart for doing things they feel right.
All of the above are just speculation.

Interesting read

If the value of Feathercoin was left up to a few guys chatting it up on a message board, we’d all be screwed. :)

I vote the attacker was bored.

Are there any protocols in development that could prevent 51% control of a coin?

The problem of FTC and all the other scrypt based coins is that they use an identical hashing algorithm.
How about we [i]slightly[/i] modify this algorithm, to make it impossible for attackers to simply switch an LTC, WDC, CNC,etc. pool to FTC?
Plus create a fork of cgminer - or talk to ckolivas to include our new hashing algorithm in cgminer. -

[/quote]No. Because they would have the hashrate anyway and could just get the new miner.
Hashrate power is not the problem. Surprise hashrate power is the problem. Merged mining would be a boost to FTC if we got it.

[/quote]Wait! Do you think an individual / group can put something like 500 MH/s at FTC?
I thought it’s maybe a rogue pool operator (or a group of pool operators) that redirect hashes from LTC, WDC, DGC, etc. to attack FTC.
I mean for a big LTC pool with 2000 MH/s, redirecting 500 MH/s for 1/2 days or so isn’t that much of a problem. Many people won’t notice they got paid out 15% less on a specific day. And the pool operator can always say it was temporary problems with the pool software, an update that took longer than expected … something like that.
We are looking for
- someone that has the hashing power
- someone that suffers if LTC looses miners / supporters / value.
imho one of the big LTC pool operators is behind this attack.

Successful attack was successful. Difficulty just went down when it was supposed to rise.

[/quote]unless the system is completely broken the system will adjust the diff back up in a few hours

[/quote]I don’t believe in conspiracy theories, secret societies - and “unlisted pools”. People always have the need to talk. Can’t keep such things secret.

[/quote]This was really nifty how they did this.
It took less than than the target time to get to the next difficulty adjust so the difficulty should have gone up. Because the attacker overwrote the starting block with one from a day before it looked to the network like it took an extra day. This made the difficulty go down.
This is the first time that I have ever seen this sort of attack. We currently have an unexpected easy batch of coins to mine. Perhaps this is the attackers way of compensating miners for the orphaned blocks :)

[/quote]I tried to say it yesterday (it was not received well) but you said it far better than I.

Haha well, the attacker(s) helped get us a lot of attention, now we must capitalize on that attention. Plus, they have not achieved their goal, Feathercoin is still alive and kicking.
