Terracoin Attack analysis
-
That means extra calculations for the miners and a big change that is likely to cause blockchain forks, any solo miners or pools who didn’t change over could be punished, if they end on the wrong blockchain.
We are proposing testing some things around extending the number of time zones used to calculate the Block average time and the difficulty. In emergency we would issue a hard fork update to all miners.
Maybe creating a miner alert (pm list) would be good preventative action for a possible hard fork?

However, some say it’s (Feathercoi) is a poorly made copy of Litecoin. We’ve got a comment by one of the administrators at bitcoinexaminer.org, Ian Irving.
There have been many instances when it’s been subject to various attacks. A lot of people don’t think it’s very stable. Its key feathure is that it’s very fast. [/quote]

According to https://coinplorer.com/Charts/Difficulty/FTC
Feathercoin has been subject to 14 GHash network “attack”, combined with the scams, forum attacks. No coincidence?
-
Interesting… Do you have a theory?

The questions are interesting after 45mins onwards especially.
I have no theory, just watchin some charts. Hoping someone would enlighten me. If there’s a bank robbery going on, its worth having a look.
-
Feathercoin 3.2 GHash /s 01:29am OK so far.
-
Feathercoin 10 GHash 16:00om 29th not OK. Block 157559

Looks like someone is DDOSing middlecoin right now. I have been getting disconnected to the pool for the past few days.
How ironic that the attack pool is being attacked :'(
The usual 0.02 BTC to 0.01 right now :-[Back to mining Feathercoin directly via give-me-coins until this is stabilized :)
-
We are being attacked now, see the stats… 2:28am - 8 GHash/s
-
Just down to 6.2 GHash/s 1:30min Block time. They are using 4 GHash/s this time.
Still 2 hours to re-target.

[/quote]middlecoin would be the size of the “attacker”, It has ranged from 3 GHash/s 4, 10 and 13.
If this is how all these multipools work then they are deliberately 51% the coin networks to mine coins at disproportionally faster rates than loyal miners. Stranding miners at a high difficulty, and swooping in again with 51% when the loyal miners have dug out the seam with a low block rate.
I thought that pools deliberately taking over 51% of the network was frowned upon? re: GHASH.IO
It is especially tragic that FTC supporters might be in that pool and are “attacking” their own coins loyal miners. It reduced the chance of a coin so much on the 27th that the p2pool did not earn a coin. That is obviously going to be deliberately destructive and leaching on the loyal miners in the network.
No, I don’t advise multipools, if this is the way they work they don’t support the coins they mine.
I also think paying out in a competing currency has ethical issues I would be unhappy to be involved with and is open to abuse unless completely transparent.

[/quote]Only just managed to get back to looking at whats been going on properly this morning and noticed this, I was starting to look around to see what was going on, did my P2Pool node fail or something similar, then I found your post. I’m glad it wasn’t just my pool, but not glad there is a company out there killing coins the way they do.

Does this benefit them or just hinder everyone else?

By doing a manually adjusted 400% attack an evil pool can get coins at 1:00m intervals, obviously, they get 4 out of every 5 coins for that period.
They are mining at 1/4 difficulty of all other members. This then forces up the difficulty so loyal miners are left mining at 3:30m block intervals and win 50% less blocks because they are mining at a higher difficulty.
They say they are mining the most profitable coin, but the “profitability” can also be manipulated as well, to the evil pools advantage.
Lets hope they were hacked. It would make me ill doing this, not happy. Another case where a nice business isn’t good enough for them, and they’ve got to screw people to be satisfied?
I really hope I’m wrong and they come on here and apologies and say it was an automatic algorithm gone wrong, some hope…
-
I’ve just noted, the increased hash rate of the “multi-pool network attack” also brings forward the expected re-target time.
It was due at 18:00pm with loyal miners, now it is 17:00 GMT.

Thanks, as always, for the excellent explanation. +rep

+36 FTC from Give-me-coins today :P
Yes its indeed an attack for the past few weeks, causing difficulty to rise up to 200.
The amount of FTC I gained daily went down to 15-21.I hope there’s some kind of new algorithm introduced to Feathercoin to counter this… If this difficulty of 127 can be sustained, I’ll never go back to middlecoin…

This month [b]+762 FTC[/b] with 7950 + R9 280x GPU :P -
The Bitcoin answer was peer pressure.
I still think Bitcoin and Feathercoin strength is network condition monitoring by the members. That is effective against the next attack too.
-
6.2GH now. Doesn’t seems OK to me.
Give-Me-Coins got 28% of the network hash rate an hour ago, right now its down to 9%.
