That he "started early" could easily be explained if these addresses were weak brainwallets
No Smiley I've received several privatekeys directly from coinwallet.
we were in email contact
and I suggested them to use https://bitcointalk.org/index.php?topic=1166928 for stress-testing

BTW, are there 791 published private keys now or have I been missing a post? 
I've counted the same number.

For 200BTC, you could generate 444444 such transactions.
This is 444444 * 225 = ~100,000,000 sigOps!
Or 100000000 / 20000 = 5000 blocks = 35day backlog.
This is for a fee rate of 0.0006BTC per KB (six times the standard rate).

Or even better, a 7day backlog for a fee rate of 0.003BTC per KB (30 times the standard rate).

This would have been a much more interesting DoS attack 'stress test'.

I am not interested in spamming bitcoin network. [for free and/or spending my funds]
I am not a rich person and bitcoin network is only a tool (or may be a "field"?) for earning funds for me and my family.
And of course I do not have 200 btc.
I do not hold btc as savings at all.
And we (both you and me) know how bitcoin network can resist in case of this attack.

I know, I thanked you before in this thread for your hints Smiley . It was a sort of joke, indeed I started with: "I'll try a syllogism". And anyway if were you I wasn't thinking bad of your actions. Sorry if it seemed so.

"I'll try a syllogism"
In my language the "syllogizm" is a "statement of the two preconditions"
this was an example of bad logic and spreading rumors, not a syllogizm

In my language too, indeed it wasn't a right syllogism, for that I was joking. But I realize what you mean, I'll edit that message.

I do not know where you took the number 200.
Seems to me that the sum is much smaller. I am too lazy and I do not have any reason to calculate their spending.
May be is was 200, but a big part of this sum went to fees while splitting to dust.
The problem was that the amount of bitcoins were already split to a small outputs - too late for SIGOPS-attack.
I do not have any information about future spam-attacks.
I do not know people who want to waste their bitcoins for a next "stress-tests"

Here, the OP:

....cut...

Tomorrow’s test will not occur as planned. CoinWallet.eu will not be sending a single transaction. 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, as a gift to the community, all of the private keys that contain those outputs will be posted publicly, making the coins free for the taking.

...cut...

I dont know if someone has verified this

Seems to me (but I can not prove it now) that the OP gave us all his private keys already.
I do not see any address which was used for dust outputs and still untouched by withdrawals from it.
There are 791 account, and it is too difficult to check them all manually.

New experimental SIGHASH_SINGLE encoding, e.g. a6e45fea2b67cf8ff85c0fcf13b477db3966cd5c19ce113a6894dbd107513ba4.

The motivation is less bytes hashed = faster verification.  (Very negligible per tx, but it all adds up).

Will take some hard work but it appears this is all worth it after all

Congrats, you've got 0.0017BTC spread across 170 UTXOs.

But I don't think this will be worthwhile for you.  I'm busy double-spending the rest of your transactions.  For example, this tx (3 confs) double spends your tx here.  In the same block I double spent 351 more of your txs.  Amaclin is also busy triple spending them.  And that's not counting all the other conflicting transactions...

Edit: To add insult to injury, block #374668 double spends 2080 of your transactions.

You *should* do the last step. SIGHASH_NONE | SIGHASH_ANYONECANPAY
How can I help you?

My religion and my wife... both of them disallow me to send btc to miners via OP_RETURN
So I can not create and broadcast such transactions myself.
But I like your efforts and want to help

Well it goes to the miners, but it's ruining the "giveaway" for people that actually want to do it.
Merging two outputs to one as you did - this destroys the network by increased traffic.
Why should 6000 nodes resend your 0.00001 values?

Quote
I don't understand why someone would do that, there's no gain for them besides upsetting the people like me who worked hard to build a sweeper program.
Just for fun. You are not 5-year-old boy. Don't cry. Next time you will be winner. Trust me.

His program just intercepts sweepers, it doesn't make its own transactions.
His program reduces spam in bitcoin network. Very fast and efficient.

I would be more understanding if it went after unspent transactions in general, but he is literally just attacking my program from what he says
Welcome to bitcoin world.

It's nothing personal.  I've also double-spent heaps of Amaclin's txs, and he has double spent mine.  I send it to the miners to avoid blockchain and UTXO bloat, which is better for everyone.

Amaclin was trying to warn you that this would happen.  All of the private keys were already spent (but unconfirmed) before you generated your first transaction (so technically you are also a double-spender!).  The transactions you did generate were sub-par (crappy fee/size ratio), and were never likely to ever be confirmed.  (you got lucky with the 0.0017BTC so far).

Yeah that didn't work when I tried it (other peers rejected the txs).  Could be a cbitcoin bug?
SIGHASH_SINGLE should be OK for this purpose.

Well, you could always fork off AmaclinCoin Smiley
