KingAfurah, will the stress test happen today? What went wrong yesterday?

So the test failed? Or, the test will be run today?
I found the previous test quite interestng and I was expecting to see updates on this test too.
I guess I will have to wait.
it was supposed to happen today, i haven't seen any time on the reddit announcement that i first saw.
a week ago they said it is going to happen yesterday, and then it was postponed 1 more day for today.

the stress tests are that if one person making just 1 transaction a second, can cause other peoples tx's to be bottle-necked and delayed....
The test has shown that if one person try to delay other transactions by sending spam, then this spam and other spam gets delayed.  Proving a small block size prevents the network from getting flooded by malicious spam.  None of my normal low fee transactions got delayed.  During her previous malicious spam campaign, I even got a zero-fee transaction confirmed on the first block.  Normal priority transactions will confirm, spam is delayed.

Increasing the block size to store more transaction spam, would be the same as upgrading your email system to store more email spam.  Filtering the spam is considered a much more sensible thing to do by most people.  In this case filtering was easy, and the spam got very low priority.

No I dont escrow anymore.
This thread is really a display about how people speak about stuff, they don't have any idea about.
Testing in a test environment is sufficient?
Where did you get that idea from? A children picture book?
There are tests you just can't make in an test environment. Everybody who worked in software development for some time, knows that.

Yes, you are correct. I was a bit enraged at first about the whole idea to spam the network. Now after the first test was somewhat successful, but fell a bit short and the 2nd test I did not even notice I am more relaxed. I never had any doubt the network could not endure this stress test, I was just questioning how we humans using it would cope with it. Many people are already antsy when their TX takes 30 minutes. Overall this was a very positive signal for me. Even 3 hours waiting time did not result in many more threads, complaining about it. All in all I still think the test was proving a point that was already well established. We need bigger blocks for bitcoin to grow further. On the other hand it also showed that 1MB can do much more than we might currently give blocks that size credit for.

We're nowhere close:

I think everyone agrees a solution needs to be found, but we're not in "panic mode" right now, which is what some people seem to assume for some reason, and others are trying to take advantage of that assumption.

What is the purpose of these blocktrain stress tests? You have a newbie account so I assume you are not part of the bitcoin dev team (I could be wrong ofc...).
Is the test for >>Academic study<< for some kinda a univericity thesis or paper?

the purpose of these stress supposed tests is to create fear mongering among members who don't really understand the repercussions of acting in haste and fear.
to change the system "upgrade" and allow endless blockchain spam for very low fees is a very bad idea for bitcoin. 

market forces and side chains/alt coins should provide the transactions per second necessary to be in the crypto world. 

(for dummies) you don't have to use your btc in starbucks if you can buy a starbucks gift card. also its not for storing pictures or websites or code.

It is crazy to think that the entire transaction network can be disturbed by so little money, imagine if someone important really had a grudge, seems like they could take down bitcoin easily!

That's the truth. P2P network are not able to scale well with large amount of communications

In traditional payment network, there is very little transaction done between participants, most of the transactions are cleared inside one financial institution, and settled between institutions. Similar to trading on an exchange, you never really buy or sell anything, you just play with numbers that represent those things in their database. This makes it very scalable, because everyone is accessing the same database at the same place

However, on P2P network, all the databases are spread across the globe, you have to broadcast transactions throughout the network to update each of them, and those communication will increase exponentially with the increase of network size. So maybe raising the block size is not a long term sustainable solution, but at least it is most simple to implement right now

I don't agree with these stress tests since they should be carried out on testnet rather than cost real users money. In any case, if you do want to be able to view what's going on during the test in terms of fees, you can check out

I'm capturing these images to make animations so if someone can tell me when whatever test starts and finishes (PM please) then I can put together a gif.

These "stress tests" are a little dumb, and nothing more than a propaganda stunt.  We all know what the limits of bitcoin are, and the core devs definitely do.
...
Agreed. The first time was a cute trick. But if this is your new hobby then you should be testing on the "test net". Perhaps you can glean it's use from the name "TEST NET".
Exactly, when governments do bank stress tests they don't disrupt real bank transactions whilst doing so!
I had thought that they should just make an Alt bitcoin, then test that, but yes, Test net seems more suitable really.

It is very interesting to see how people reacts to the situation

When a bank is closed during weekend, would people change to mobile bank or just wait until Monday to do transaction again? What if that wait will be one week/month? Or you just pay a little bit more to get your transaction through? Usually people are willing to pay a little bit more to get faster delivery

Greece just had a capital control today and the maximum money you can take out from any ATM is 60 euro, and we all saw that does not affect Euro's value that much, in fact Euro even rose

It's like me putting a pot of water on the stove at 150C, and saying, "see, it boils!  the stress test proved itself!".

It defeats the purpose.  Those conducting these tests know exactly what the limits of the network are, so obviously if you push a test over those limits it's going to fail.  Same as if I said I'm going to "stress test" aluminum, put it under a temperature of more than 660C, then say, "see, it melted, hence failed the test!".  Well, I knew from the onset that was going to be the result.



no....
its like a bunch of grumpy maids saying that the pot of water wont boil until 2000 people breath on it and generate enough heat and prove there is a 2000 strong demand for hot water to make coffee...

the stress tests are that if one person making just 1 transaction a second, can cause other peoples tx's to be bottle-necked and delayed.... then waiting for a year until the demand actually forces a upgrade is just waiting for the problem before looking for the best solution...

it is like letting someone sodomize you in your own bed.. before setting rules to not let anal lovers follow you home.


did you know that something like this happened before..
many core coders didnt want to strengthen and expand bitcoin to cope with change.. and it took satoshidice to spam the network for the coders to then stop sitting on their hands and implement code to decrease the spam..

most coders think they are gods. that their code is perfect and does not need changing.. it always takes outsiders to prove them wrong..

to me coders are like people who wont lock their doors and allow themselves to be violated a few times before thinking about whats needed to secure things.

There are over 3000 unconfirmed transactions now. Is that the normal number?

There were quite a few closely spaced blocks but now the gaps are increasing and the last block was almost 1 MB. The tester said the test would run for 24 hours. Is there a chance it might start disrupting the network if it takes longer than normal to find blocks from now on?

Yes, it's a "normal" number. If blocks take longer, the impact would be bigger, as it would take more time for confirms to happen in relation to if blocks were found each and every 10 minutes... But it's worse when blocks don't include any transactions.

You are right to some point, it will fail, but it will also give some useful information.

Oh, definitely.  I'm more than in support of stress tests themselves, as they're an integral part of any network.  Basically, I'm just questioning the motive of these recent "stress tests" due to the timing.  I'm assuming it's just Gavin and Mike trying to say, "see, bitcoin is broken, move over to XT", although I could be wrong.



Bitcoin is both core version and xt, bitcoin is not broken. The only question is; is it needed to increase it's block size , and i agree it is.
It makes much more sense to do the "upgrade" while it's still doing the job, rather than wait for it to be too late., don't you think so ?

cheers
I agree with this.  I think this sort of thinking ahead is very important at this stage.
