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.


1500/20 wouldn't be out of the ordinary, also the transactions they are sending out should be easy to spot if you watch blockchain.info or whatever since they are all specifically crafted to use up the most data for the least amount of fees that the network will accept

How can you tell whether the stress test is going on? I think it might be, but I'm not sure. I have seen a couple large transactions going on, but not at the speed I would expect the test to be creating them at.

That is after two blocks were found so the actual number of transactions seen by the network are greater.

It seems that most of the major block explorers are running extremely slow right now so that number may not be accurate (although this could just be my internet - other sites are running fine though)

But running the numbers, you are probably right as that works out to roughly 1.25 tx/second.

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.

My God I totally agree!

Damn, the thing i can think is why doing that?

Come on Coinwallet.eu, why are you not sending out transactions?

Why would you even claim to perform this test if you don't actually conduct it? Is Coinwallet.eu simply trolling?

It's about 11AM in my timezone as of this post, and as I recall they didn't start last week's stress test until sometime between 2p and 4p I think

TBH this test it's being executed poorly, and it's likely someone lobbying for the block size increase. However, this test could achieve the opposite if well executed, showing how the general infrastructure is not ready for 8Mb blocks, specially with a massively full mempool and nodes and miners crashing randomly.

Expecting this kind of "experiment" in the very near future with more funding and custom software for crafting and injecting transactions to the network.
That would definitely be interesting.

Ok unless I'm getting hallucinations from watching all these transactions I think it's underway. 2200+ unconfirmed transactions and 1.15 mb in the mempool and only 5 minutes since the last block. We had like 5 blocks in 10 minutes before this which was keeping it at bay. I've been noticing lots of transactions that may be stress test with lots of inputs and outputs and exactly 0.01 btc being sent.
This is far from the results predicted by the OP for the first minutes of the "test". So something is likely wrong in their execution.

They only were going to generate 1 mb of data every 5 minutes, the current rate of data increase is in line with or exceeding that. IF they can sustain the test instead of crashing it should add up over time to a big mempool.

You are right, I misread the amount of data.

EDIT: Just got 3 blocks in 3 minutes, lol. Blockchain is way faster than usual this hour and the test the OP describes wouldnt be able to keep up.

8 blocks in 30 minutes.

Miners luck goes against OP's luck, this should normalize with some time.

Actually seems the blocks have quite low numbers of transactions.

363069 is completely empty, other than coinbase.

That's not going to help.

According to http://statoshi.info/dashboard/db/transactions, there is no noticeable change in either the "transactions per second" or the "bytes per transaction" charts in the past few hours. Is the test really going on?

4 of the last 5 blocks were filled to the limit, could be back underway. Mempool already passing the block limit less than 1 minute after the last block.

look at the transaction sizes, too small
