So are they doing it again?

Yes, they are.
Somebody is sending (right now this wave is over) small amounts.
You can see these transactions in blocks. For example one of latest blocks:
https://blockchain.info/block/000000000000000008763b540d4b795c96a8e5277332ff227d7c3bf78addeed8
Scroll to the bottom and go up. You will see a lot of transactions which sends 0.00001 to several addresses

Oh Ok, I see! I guess to be safe, I need to raise the fees to 0.0005. But like somebody said above, this does fell like extortion. I hope this will be solved soon.

So are they doing it again? I have a stuck transaction again event though I sent it with the 0.0002 fee.

Do we have any clue who is doing this and what is the permanent solution except the temporary solution to raise the tx fee.

I have a feeling of being extorted for sending my money:
Send us double the normal fee, or your transaction will be delayed indefinitely Angry

It costs whoever is doing this 0.0002 for each transaction he spams. He cannot continue for long. Last time lasted for 5 days. I am not sending anything until the spam dies down.

Yeah... maybe the new game is to start spam attacks occassionally for a couple hours. That way bitcoiners never know if their transaction might be caught in a spam attack suddenly. And maybe they pay more from the start then.

At least it stopped now. Im too tired of these ... persons that i dont even want to get angry. Cheesy

It seems that all his transactions have fee 0.2 mBTC/kB exactly. If you use a slightly larger fee, your transactions should go through right away.

This site may be useful to follow the "test".

It does not seem to be an accidental surge of traffic. There was a sustained excess All these excess transactions seem to have the same fee (0.2 mBTC/kB) so transactions that pay less than that fee will be delayed until the backlog clears.

According to that site (approximate values):


Normal incoming tx rate         N = 0.67 kB/s (400 kB/block)

Peak incoming tx rate in test   P = 2.33 kB/s (1400 kB/block)

Apparent network capacity       C = 1.32 kB/s (790 kB/block)

Current backlog                 B = 13 MB.  

Current incoming tx rate        R = 0.90 kB/s (540 kB/block)

Expected time to clear          T = B/(C - N) = 5.6 hours (33 blocks)

Blockchain is at 7k unconfirmed at the moment.

7k unconfirmed is not too bad. We had 28k unconfirmed in the last stress test session. If the numbers return to normal in a few hours, I think it's just a co-incidence that a lot of people want to send coins at the same time.

Looks like it. 2.5 hours and no confirmations on todays transaction.

Same here, still no confirmation after 4 hours.

Wow, looks like I finally got lucky on this front, I sent and received some BTC yesterday. Last two times these "stress-tests"/spam-attacks happened I was caught up in the middle of it waiting for a confirmation for hours.

I doubt that there will be a report. As far as I know, there is nobody, who claimed that they did the big one. coinwallet.eu(whoever the hell they are) got pretty silent.

In that previous report that I linked to, they say that they had aborted the test for technical problems, they were about to retry the full test, and that their goal was to get 200 MB of backlog. Which they did. I see no reason to think that the test was done by some other entity.

On the other hand, no one knows who "coinwallet.eu" actually is.

There's no more stress test, which is nice. I hope the guy who did it will share some info with us.

After the first aborted attempt, Coinwallet.eu posted a report of the method and effects on reddit. Hopefully they will do the same for this one.

I hope for it too. If yes, please post it here because I don't have Reddit account.

BTW. you can read reddit without an account.

I know, but I don't have reddit account so I'm not checking reddit, logic..
