        Check this thread to see which pool has fixed the stratum problem.

              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…

                    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 ::)

                      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.

                        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?

                                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.

                                    Here’s the results of the analysis of extra coins mined by the attacks during the last 3 days. Its in terms of “Days of coins” mined.

                                        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.
