Is there some convinient web page for monitoring attack and state of network, except blockchain.info?

blockr.io is another one that is pretty good.  My full node seems to have about 6 blocks worth of transactions in the memory pool as of right now.  Should be interesting.

My transaction has been waiting for confirmations for approximately 3 hours now.  I wish I had seen the warning on this test.  And I wish these kinds of experiments were being carried out on testnet.  Sheesh, it's not that fun when you're the one who got disrupted by the experimentation.

Well look at the bright side. Now the "do not raise the blocksize limit above 1mb" crowd will learn the hard way. People don't want to solve problems until those problems are felt by themselves.

Ok, I'm trying to look at the bright side rather than the annoying side, but FWIW, I wasn't part of the "themeselves" that needed to feel this.  I had no issue raising blocksize limit and I stil wish these dudes would perpetrate elsewhere. 

[Minerkev]

Lol...waiting long? What about higher fees?

You can fill up any block size limit with this kind of scam.
It is not a question of the value of the actual block size limit itself but a
question of the price you have to pay for scam.

 What shall we learn from this kind of experiment:

1) We need a limit on the block size. This limit has to be
   sufficiently large for day to day transaction amounts but
   sufficiently small to prevent scam to enter the blockchain.

2) There should be some self-adjustment of fees. Clients should be
   able to inquire from the full nodes an estimate for a reasonable
   fee based on the current content of the mempool. This would allow for
   moderate fees under usual circumstances but would increase fees in
   times of flooding the blockchain with scam and would turn scamming
   into an expensive exercise.

Wow, these guys were spot on with this test.



I wonder if $500K in BTC was set aside.

Just normal calculation would tell me transactions would take days! If not weeks.

This is a serious problem.

Interesting, viewing an address is failing on blockchain sporadically.

Receiving this error - "Maximum concurrent requests for this endpoint reached. Please try again shortly."

^^ This.

If my client had warned me about the situation I would not have sent my BTC this morning.  'If my client had said "you're going to need to pay an exorbitant amount in fees if you hope to have your transaction confirmed anytime today thanks to a "stress test" that is currently being perpetrated on mainnet.' I would have appreciated the warning and cancelled the send.

I was going to play a game for 30 minutes or so before work.  Now, 4.5 hours later, my BTC is tied up in some unconfirmed transaction.  Hey, OP, uh, thanks!

[Ibian]

So what makes my coins so special? Nothing over 2 hours for 6 confirms yet.

According to the original calculation they provided, the unconfirmed tx should be around 55MB by now.
Currently, it is only around 8MB, which is not that bad. Miners seem to be chomping away fine.

So the stress testers either stopped or it was a scam to manipulate something unknown at this time (double spends?).

Currently, this only effects users who did not set a higher fee, to get into next block.
Currently, the average fee for next block seems to float around 0.0003.

pay the real fees ... 

[Meuh6879]

good, normal fee is 0,00001 BTC usually ... and 0,0001 BTC in 2014.  (android wallet)

Well... now current fee is 0.00053, for next block (in theory).

Seems they started again after stopping for 2.5 hours.

Hey, cute eyeball rolling smiley!  If by "the real fees" you're referring to the fee my client suggested for the transaction, that's exactly what I did.  If you missed the context above about a potential client that would warn you about spam-attacks and "stress-tests" and calculate a fee suggestion to get you confirmed, I dunno, today, then back at ya.

Whelp, I paid 0.00002BTC, so I guess I'm double what you consider normal.  Hey, thanks Meuh6879, for the help!

As of ~8:03 PM GMT, there are roughly 9,200 unconfirmed transactions with total Tx fees of ~1.76 btc that are a total of ~10,100 KB in size. Last block was found roughly 35 minutes ago and the 6th last block was found roughly 90 minutes ago.

Raise the limit!

Raise the limit!

Lol. Isn't that Peter Todd on the right? 

[AgentofCoin]

Here is a good site to watch the memepool as a graph, on the right hand side.

Dark Blue are unconfirmed transactions that are old and "were received since the confirmation of the last block".
Light Blue are unconfirmed transactions that are new and "were received since the confirmation of the last block".

You can also see how much the miners are adding into the blocks, when found.
