Feathercoin network up 3 % over 2 days- NETWORK ATTACK?

flound1129

There appears to be some sort of issue with the FTC client. I’m not sure whether it’s related to the attacks or not, but in my client, ‘mintime’ was almost 2 hours off from the current time for a while, resulting in many rejected shares.

It’s still over 30 minutes off as I write this:

[code]$ feathercoind getblocktemplate {} | grep ntime
“mintime” : 1374235229,
$ date +%s
1374232575
$ bc
1374235229-1374232575
2654
[/code]

This caused 100% rejected shares on my pool for about 3 hours until I patched stratum with a larger allowance for incorrect ntime.

Hey, Is this ligit he got 7 blocks an hour since 21:30pm yesterday

af56e40d17… 52384 2013-07-19 14:00:57 200 13200.4419994 FTC
34c0324d35… 52385 2013-07-19 14:01:22 200 13400.4419994 FTC

Gotta go out, hope this is all stopped when I get back, I note nutnuts p2pool has not payed out since 6.00am and thats unusually unlucky.

Hope it is Ok?

Seems FTC were dead from now :( It is a pity, hoping that this will be the currency of a minimum replacement for litecoins :(

Seems that the diff/retarget time is completely out of wack.
Also havent gotten my latest block found confirmed/unconfirmed in ftc client for several hours.
Only info is that the miner has found one accepted.

Anyone care to comment about this? time for checkpoint?

Drjones

Yes Just seen this???

Why is difficulty going down with more hash power added?

Anyone have any idea? looks abit f0rked ;(

Something is very very wrong. Re-target time is negative and keeps increasing in negative value. Does this mean it will never reach 0 hence it will never re-target?

Edit: 69,505,175 KHash/s :o looks like another attack?

The attacker found a vulnerability in stratum and was using that to block the hash power. Because pools weren’t finding any blocks, even orphans, miners started jumping ship.

This attack isn’t one person but a group. I’m starting to think either these attacks are based on a grudge or the removal/down fall of ftc will make money for someone’s other project. This is to thought out and concentrated for sh*ts and giggles.

All right everyone, calm down. Everything will be okay :)

These attackers are pretty ingenious. I’m really keen to get the [url=https://forum.feathercoin.com/index.php?topic=1878.msg15226#msg15226]Advanced Checkpointing[/url] implemented so that attackers have to mine blocks normally like the rest of us.

What they are doing to us now they will move on and try on others. We are being forced to evolve which is no bad thing. More than anything these attacks help spread fear, uncertainty and fear as many do not understand the attacks and over estimate the damage the attacks will do.

Actually, it started happening about 10hours ago. a quick way around it was to change from stratum to getwork pool. Thus just temp change to getwork, its a alternative solution… But I guess most pool should have resolve this problem…

Multipool was patched last night.

Low difficulty without the exchange rate going down, looks like those multipools are aiming their hash at ftc.
at 0.00088 ftc/btc and a diff at 32 (at the time) ftc was REALLY profitable ::)

FTC is not dead.

If it’s dead, does it mean we can all avoid the insane back to back late nights? :) We were attacked, we continue to push forward.

as of 8:15pm this addr4sss got 47,000? the block rate is sometimes seconds. I thought it was fixed so he couldn’t exploit stratum.

Could we get some live crypto network statistics / charts on the forum, so the community can monitor more easily to diagnosed any further suspicious activity, and not so biased to “Tradeing” sites lie coinchoose.

Perhaps this explains - the block average rate prediction of the start date, anomaly, i.e. the difference to the actual start date is a measure of fraudulently included blocks during past attacks.

So something along the lines of a comparitive line chart of hashes from partner coins, litecoin, and bitcoin? Is there a online db somewhere that a historical hash rates can be pulled and diff adjust?
