2015: The year of the stress test

The nice thing is that bitcoin just keeps on keeping on.

I didn't know another "test" was on until I read your post. I check the explorers, we no have 28k unconfirmed transaction totaling 310M. The good news is nothing a 0.0002btc/k fee wouldn't solve.

The part I don't understand is why are some people burning their bitcoin to repeat these tests? They haven't proven anything and it's not bringing the network to its knees. Why waste money?

I don't really understand the motivations for some of this stuff, but it is important that it happens. It won't get anywhere unless it's given a beating and comes out the other side the stronger for it.

I was not aware of this stress test either. It looks like it started sometime last night but the significant increases have occurred today. Apparently some people are persistent when it comes to disrupting Bitcoin. The good thing is that Bitcoin survived everything that they're throwing at it.
This is also a sign that someone should hurry and work on a better spam filter. Spam transactions should be identified by various factors and completely ignored by the network. There needs to be work on both this and malleability.

That which does not kill you makes you stronger. We shall simply learn and adapt. An idea whose time has come can not be stopped.

I wasn't aware either. It seems that I wasn't the only one. Yes, many, many stress tests and attack on Bitcoin network this year. Who's doing it is a good question? It seems to me that the opponents of the certain things in the Bitcoin network are behind these tests.

Good thing is that we will eventually learn like this and improve our network. I honestly think that what doesn't kill us makes us stronger in this case and this is exactly what's going on. Bitcoin will prevail in the end everything!

Here we go again..

Im a bit worried this time though, because combined with the malleability of transactions this could become a painfull thing.

[RoadTrain]

What I've noticed:
1) it's a lot of ~15kB transactions spending 0.00001 outputs with miniscule fees (~1 satoshi/byte);
2) it's getting confirmed by BitFury mostly (only?).

Is BitFury cleaning the UTXO set?

Yep ... bitcoin connexion (RPC server) satured (100% CPU).
Keep connected to P2Pool, but it's hard ...

this tests prove everything ... 

but if you don't mine, you can't view this ... 

[UserVVIP]

Why do people think it is a good idea to do stress tests?

It seems like a waste of time and money.

I can think of groups that could benefit from such a thing. Whales and supporters of bigger blocks for example.

Perhaps a government organization or private corporation is conducting this attack. The fees are nothing for an entity with a high budget.

[Meuh6879]

Clearly, they don't pay the fees ...

In that case i follow conspiracy ,some people are closely looking btc when btc is starting to grow somestrange things are happening.230$ level has benn defended,number of transactin is growing.I think it is to disturbe btc one time again,maybe to accumulate more cheap btc

[Meuh6879]

to the sky and behond ...

Stress tests could only prove that the system is robust. Just be careful that the transaction will only get through when there is at least 1 confirmation.

Is this the biggest mempool backlog ever recorded? It's gotten to the point that core devs started suggesting that node owners should set spam filters...

Of cource this particular piece of advice came from no one else rather than Luke-jr

I think that it is. I don't recall it ever going this high so the attack is pretty 'powerful'. They have not started telling people about spam filters right now. There was talk about it before and if you properly set it you will not be affected by the spam.
