Are we stress testing again?

[RoadTrain]

Unconfirmed transactions still at over 11,000 so this spam fest is continuing then. I really think it's time for miners to reject all transactions carrying no fee. This rubbish will stop then.

It's actually not stress test anymore. Just some people trying to spend the dust that this test has created.

Still running at around 11,000 unconfirmed transactions - https://blockchain.info/unconfirmed-transactions

This seems to have become the norm now, my memory is terrible but I swear the average used to be somewhere between 500 - 3000 at any one time. It's terrible really, how long are these stress tests spam attacks set to go on for?

According to statoshi.org, there is still an excess traffic, ~3 transactions/second (compared to the average of 1.4 tx/s that was the norm before the "test").  

Yet the backlog is being cleared: from its peak of ~200 MB iy is down to ~35 MB.  The slow rate of clearing is due to the 1 MB block size limit, coupled to the unwillingness of many miners to mine full 1 MB blocks.  

On the other hand, most of those transactions in the backlog are paying low fees, so the fees that are needed to get prompt service are almost back to the pre-test levels.

that was actually such a cheeky play. they used a lot of known addresses (whose private keys were known) like the brainwallet ones and also released hundreds of other private keys.
the people's greed is now continuing the stress test / spam attack

Interesting.  So it is potentially possible that BitPay never gets that transaction, and I receive what I purchased for free.

Yes, but the merchant should never ship their products without having at least 1 confirmation.

Though thats not how bitpay works. They only wait until they see the transaction and they have huge turnovers. I wonder two what will happen. They will have huge amounts of coins that dont reach at the moment.

My transactions still have no confirmations, and nothing has been communicated to me from the merchant or BitPay.  I am going on almost 36 hours since the initial transaction happened. 

Transactions have cleared, and my wallet is empty.  I didn't try any double spend technique during this time, and it took around 48 hours to complete the transaction. 

[scarsbergholden]

There where a good amount of double spending tries during the stress test was anyone affected big with this ? or where there just most tiny transactions ?

[Quantus]

Transactions per second is still really high but the back log is being cleared, how is this possible?

[clipman77]

Now everything is working normally, I think everything is over.

[Meuh6879]

Yes, mempool decrease !
20 000 transactions ... need to flush.

Yes, significant reduction over the last hours.

I would be interested to see what happens to the fee policy of major mining pools as well the average fees paid by users in the coming days and weeks.

There are now only 2742 unconfirmed transactions and that should result in the backlog getting cleared fairly quickly. Nobody will be waiting 48 hours+ for a transaction to confirm from now on unless the stress testers start again. They had a limited budget and they probably spent it all by now.

Yes, my local node also shows significantly less[1] than the server. I might restart it later to clear the mempool.

I have seen that the transaction that doesnt get verified get back to the sender ! So the stress test have just delayed the transaction to be confirmed

Some nodes "censor" what they consider "spam" transactions in an attempt to cut down their own load and prevent them from being included in the blockchain.  This site still shows ~18 MB of backlog (bottom plot), which is clearing at the rate of ~10 MB/day.  

The backlog now seems to consist mainly of small-fee transactions, so the fees required to get confirmed in 2-3 blocks are back to almost the pre-test levels (when there was no backlog, so higher fees should not have bought faster service).

Coinwallet.eu, the entity ostensibly running this test, claimed originally to have a budget of 5000 euros (~5000 USD), and the goal of creating a 200 MB backlog of unconfirmed transactions.  They reached that goal on 2015-07-11, and the backlog has been clearing since then.  As predicted, it would take about a week to clear.

The incoming traffic rate reached a peak of over 110 tx/s on 2015-07-07. The average pre-test traffic was 1.4 tx/s, and it rarely went above 2 tx/s.  The network's effective capacity is less than 4 tx/s.  There are still occasional bursts of incoming traffic at 20-20 tx/s, and a background rate of ~3 tx/s. The extra traffic may be other people collecting their gazillion outputs that they sent to donation and public addresses.

Transaction fees added to about 20 BTC/day, on average, before the test.  This plot Shows that the miners collected so far 9 + 25 + 30 + 22 + 19 + 17 + 26 + 14 + 8 + 8 + 7 + 5 = 190 BTC of fees, above the normal amount, as a result of this test.  At today's price, that is ~52'000 USD of extra revenue for them.

aand its back on.

Oops!  Indeed. "Nobody expects the Spanish Inquisition!"

Looks like it was just a last batch of ~10k TX. Looks like we are back to "normal" from here.

[Herbert2020]

it seems like we are back to good ol' days of fast transactions, i just got a 5 minute confirmation which felt good

Yup, just checked my mempool... only around ~500 transactions. It seems almost too low
