[/quote]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 ::) -

[/quote]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.

[/quote]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?

My investigation last night showed a potential insertion of the odd block, not the massive multiple obvious inserts. This is more insiduous as these inserts are coins being stolen and would be more difficult to trace.
What tools do we need to do a weekly analysis the blockchain, and highlight all potentially dodgy blocks?
Please test the current block chain for any anomalies urgently. Post these Blocks and fraudulent addresses on the Investigations Page.
Some anomalies may be due to bugs or merged mining going wrong, they need identifying urgently for attention.
I have posted the incorrect times of some of the blocks as a new potential new attack vector and am doing a new survey this morning to see how many more coins were stolen last night.
If there was a minimum block time, incorrect dates would not have been been confirmed. Each should also be confirmed if it is consistent with the previous and post block.

[/quote]If that is the case all coins are affected, these show the attack was too the pools and all coins, the Bitcoins and Litecoins would be the most profitable to steal.
The charts show the change in “additional block days” above specification from 19th to 20th.7.2013.

You really should look at the chain as a whole. Looking at the entire chain you can see that Feathercoin is actually behind in blocks per design, which means there were periods of time where no blocks where found in the 2.5 minute allocation.
Time of first block: 1366147060 (2013-04-16 21:17:40)
2.5 minute blocks (150 sec)
Current Unix Time: 1374421048
Seconds Passed since Block #1: 8273988
Estimated Blocks@ 150sec each: 55160
Actual Blocks in Chain: 54471
# Blocks Behind: 689

Hi BigVern, thanks for checking my calcs
I have already noted previously, Feathercoin was much further behind the coin production rate, before the attack on 19th July 2013.
It will be interesting to see if you see the same reduction in missed blocks I have seen on my analysis.

[/quote]DigitalCoin is one I choose to examine. Now with digital coin, the genesisblock was mined 14 days before the first block was mined - which is unusual to see. In line 2048 of main.cpp of the source code has “block.nTime = 1367867384;”, so it’s probably from the genesis block timestamp.

23rd May to 21st July Chart of Feathercoin Blocks per day against specification (BigVerns Data).
Number of Blocks
should have been produced : 51840
were produced : 32502Unusual low block production rates : 7.5.2013 to 7.6.2013
Low block rates from Blocks 32463 to 33200
Could it be the block rate was being suppressed for a month, in a seperate more subtle attack, in order to have missing back coins to steal during the main attack?
Surely only producing 9 blocks against a required 575 should have rung some bells with someone as being incredibly unlikely?? Or extremely incorrect difficulty adjustment.[attachment deleted by admin]

that is why we had a hard fork at 33000 with big bounties to reach it. this was to correct diff adjustment that was going to wide. So the diff 188 was killing FTC with a rate of a block every 2H as only hard core supporter mined FTC at that time. so the data is ok and the chain also.
so (block reward * price)/diff give a ratio that can be compare to other scrypt coins for profitability if price goes up diff can go up if diff goes up without price going up your screwed with a high diff and low mining power. That what happen with the 2016 retarget and big change on diff that goes up and price fall. profitability was very bad so miner goes away and high diff-low hashrate makes very very long time between blocks.
