I really hope that this isn't just some attention grabbing false claim.  I'm looking forward to seeing this, and I hope that you are able to actually keep up the volume and size (in bytes) of transactions that you say you are planning.

Cool, I enjoyed the last test, even though it failed.. By announcing, less people get trapped right before the test by sending with too low a fee.

CET is GMT+2 instead.
It is 12:35 GMT (FYR: http://time.is/GMT) at this moment, so the test will start in 25 minute.

This will certainly delay normal transactions. Results from last test show that 0.0001BTC per kb transaction on average took 9 blocks (~90 minutes) to confirm.
Really?  I went on with business as usual during your last pointless DoS attempt by spam, using my standard fee of 0.00002 BTC/kB, one fifth of yours.  All my transactions confirmed with no delays.  This is of course normal non-spammy transactions with normal sized outputs using oldish inputs, so I guess the priority of my transactions were a few orders of magnitude above your spam.  This is true for most non-spammy transactions.  Have a closer look at the delayed transactions.  It is probably just other spam delayed by your spam.  But please spammers, empty your pockets before your gangrene eats the rest of your brains as well.  The miners deserve their fees.

They have a bit of headstart with this backlog. They must have started the test by now. Let's see if everything works out this time

So what's the point of this now that you know it won't actually delay legit transactions?

The point is to study the effects of a mempool size of >150MB which was never reached so far.


I would be interested to see how quickly transactions are able to propagate throughout the network as the size of the mempool increases. I would make a hypothesis that transactions would take substantially longer to propitiate as the mempool increases, to what extend however I am not sure.

If it is more then an additional few seconds then a new way to execute double spend transactions could have been discovered. An attacker could flood the network with transactions, then attempt to spend the same inputs twice, each originating from diverse nodes. The victim(s) would not even realize the double spend attack for a long time.

As of  ~1357 GMT, around 1,400 unconfirmed transactions, total fees of ~.39 BTC and the last block was found ~4 minutes ago and 6 blocks were found in the last ~55 minutes.

Why not use the money to dig a few wells in Africa instead? It adds a little more to the wellness of the world.

Proving that Bitcoin is a broken mess despite how much power it wastes would be a much better net gain for society

Anyone with a modicum of awareness should know that it's not all that viable to continue as it is. No point in wasting further money when we know what'll happen.

Not cool that they would hype it up like this if it ended up being totally fake. My initial suspicion was they spent all their BTC on the first test and didn't want to admit it, maybe that's right.
There are a net 1,500 additional transactions in the mempool over the last ~20 minutes and two blocks were found in that time.

I think it is pretty clear that they are still in the process of doing the test.
