I am NOT saying that, that transaction is invalid.I am saying that, that transaction is non-standard.Try to relay the given tx and see yourself.
take it confirmed

Either f2pool mines non-standard tx's or either https://bitcoin.org/en/developer-guide#non-standard-transactions was wrong.

I thought this was an interesting experiment, so I tried it:
double-spending the 0-conf coinwallet "sweeper" spam.
Below is a quick write-up:

@elmad, this is an answer how to create the transaction without retrieving utxo from the blockchain  Grin



Thanks, later I thought that you meant double spending but I have not researched the procedure. Thanks to you and @basil00 for these posts.

The correct is: Exception: standard null data outputs may receive any amount, even zero satoshis.
"standardness" - is not consensus protocol rule. Any client may use its own rules.

Some of the older encoded txs (XX, XY, XW, R, DS) will likely bounce around for a while.  I've set my script to double-spend them.
No need to do it. Because my script converts everything to "my address".
And your script converts my result to OP_RETURN.
Unfortunately to me, I can not beat you Smiley

OK, the game is over. From this moment all dust outputs from compromised private keys will go to miners only.  Grin

@basil00, You took my profits, the son of a bitch !  Grin Grin Grin


@amaclin what fee were you using when you took profit? How many satoshis for byte?

I took ~4BTC from these keys. What do you mean by "useless"? Useless for you?  Grin
You did? Please give us proof and share the knowledge of how you did it. In the process you've sucessfully cooperated on the evil plan (i.e. harming Bitcoin). Honestly, if it were a little less damaging I would have kept trying stuff. People should have stopped this when it began, yet they continued trying to get small bits of money.

Anyhow, from the looks of it the number of TX is persistent but the mempool size is going down. We're currently at: 166,845 (120MB) on blocktrail. It will take a while before this goes back to normal.

Also, I think there will be no more private keys here anyway.


They have wrote :


Instead, we will be giving away over 200 Bitcoins to the community. Previous tests have involved splitting bitcoins into hundreds of thousands of tiny outputs.

Now I don't know how much private keys they did release to the community so maybe they will give more private keys. Who knows?

He did for sure, in the past I read from him more advanced scan on the blockchain than this, he has bots that scans the blockchain for unsecure priv keys, and these things need a good knowledge of ECSDA signing and bitcoin protocol. And you can read in this thread his talk with basil, if you understand what they say. Is not that a proof? It's disturbing reading these doubts and pretending explanations. If you read this thread he gave hints, has he to do all the work for us? Without you do your homework to know and to understand?

Regarding the evil plan, I agree that the intent was this, but if Bitcoin doesn't resist a such attack why Bitcoin should survive? We can se that it resisted, and you can see that after @basil posts that amaclin swicthed his bots to clean the dust giving all profit to miners, so you should thanks them for clean the dust if you care about the mempool size problem...


P.S. If i did 0.23BTC in some hour at the right time with my "learning mess code"...

Different.
I am changing this value several times a day depending of...
I do not know how to explain.
This is a game. Like casino. The gamer in casino uses different bets: bigger, smaller....
I do not know why do I change algorithm parameters Smiley It's a game. It's only a game  Grin

but if Bitcoin doesn't resist a such attack why Bitcoin should survive?
The problem is in other place.
And all decentralized crypto-currencies can not resist and will die.
I think soon.
But i do not know when.

Do all blockexplorers ban your IP-address?
Aren't you able to walk through the dust addresses and check for withdrawings from them?

Yeah it's not so simple, I have to keep sweeping through and there's more unspent outputs. 0.1 BTC now and going up nicely Smiley

Most of all this was excellent programming experience, which I will immediately use for my decentralized forum.
I'm donating all my earnings to the decentralized forum too.
https://tradeblock.com/bitcoin/address/1AyRmvqe99mRWU69w8Hbaeej8twMpdeiKm
Transaction Count   12396
Confirmed Balance   0.00044846 (these funds were on your balance before)

Seems to me, that you will earn nothing. But go on! Keep trying!

tradeblock and blockchain barely show the balance, tradeblock has the correct transaction count though.
The only significant number for you is Confirmed Balance
All other numbers measure your work, not your profits

So much for the 'stress test', turned out to be a massive waste of money and needless bloat to the blockchain by a group of plonkers calling themselves 'CoinWallet'.
Way to cop out at the first sign of trouble ladies Tongue
