I openly invite you to try your best with DGC.  Smiley

The gauntlet has been thrown.  Someone should make a youtube video as you destroy DGC.  With a ddos on the top few pools it becomes easy to achieve.

man talk about transference of aggression.  BTC and LTC prices collapse, mining profits shrink to meager gains and all that pent up rage is looking for a target.  epens that small?

shhh dont taunt them, that will make them angrier.

Instead of attacking coins, why dont they just spend the same time and effort  supporting the coin they like by creating products/services and other interesting places to spend them?

Because attacking coins is quick, brainless, and yields instant profit.

It's certainly not brainless.

You have to know what you're doing to attack a coin.

I thought the stated plan was just to DDoS the big pools and use somebody else's exploit? That's script kiddie level stuff - it's got amateur hour written all over it.

You'd have to find a botnet first

And who said anything about using someone else's exploit?

If it was that easy every alt would have been attacked already.

or follow a tutorial  

1. Sync client with network
2. Backup %appdata/coin_directory
3. Send coins to exchange and wait for 1 confirmation
4. Close client.  Disconnect internet.
5. Overwrite %appdata/coin_directory with the backup
6. Launch client.
7. Create new receiving address.
8. Send all your coins to your new address
9. Wait for transaction to be confirmed and you have found more blocks than the real world network
10. Reconnect internet.  

Your coins are at the exchange, but still in your wallet as well.

Oh, and you need another machine on your LAN running the client as well.  (you need at least one connection to anyone to mine)

Your transaction is recorded onto the blockchain so when you overwrite with your previous file, you won't be able to spend them.

Your client will see you already spent those coins and they'll disappear once your blockchain updates.

You're wrong.  You have the longer blockchain which doesn't contain the transaction to the exchange.  Your blockchain gets accepted by the network. 

[R-T-B]

I don't even have to understand the protocol fully to understand that's complete BS.

[FiiNALiZE]

How exactly will you have a longer blockchain if you rewrite your synced blockchain with an older one?

The older one will not contain the transaction to the exchange, true, but once it updates and syncs, your client will see you already spent your coins.

What exactly are you trying to prove here?

Dude trust me, if it was that easy, crypto would not exist anymore.

It's in step 9

[FiiNALiZE]

Yes but your other computer on the LAN is connected to the network so it'll see you already spent your coins.

If disconnect both, in order to get a longer blockchain, you'll have to generate blocks; good luck with that.

BTC difficulty is currently 19,339,258.

You'd need to have 51% of the hashing power, hence why it's called the 51% attack.

You kinda left that step out.

You're right - don't turn on the slave system until you've disconnected the internet.  The client will sync with your main system.  (just add connect=192.168.x.x to the config)

EDIT:  51% attack implies 51% of the hashing power.  Sorry for not making this even more brainless.

There should be another step in between 8 and 9: Get 51% or more of the hashing power of the coin you want to attack.

Otherwise the valid chain will generate blocks faster than you.

That's usually the hard part since most of us don't have $100k+ to spend

Edit: Sorry for not understanding your post since you left the MOST IMPORTANT STEP OUT.

At step 9, you indeed need to generate blocks faster than the real network ... That's why you need some horsepower and that's why it is "recommended" to launch a deny of service on the main pools to ease your chance to get a longer blockchain.

I'm not an expert, but I suppose you don't really need 51% of the hashpower ...  the more you have, the more likely you will generate a longer blockchain in a given timeframe. At 25% I suppose you can already be considered a threat

You can 51% Elacoin with about 3x7950.  I know quite a few people with 10-20 MH/s each which could kill a good number of the alt-coins tomorrow.
