I thought this would be against your policy of not spending money on attacks? I changed my mind

At least the attack is proven to work in practice.

Governments do not need to "destroy" bitcoin. Because there is no danger from it. Governments steal our money but because they have to pay so much interest on debt there is no money left for a bitcoin attack. By the way, politicians still dont understand what Bitcoin is. Good for us, because when criminals dont understand something they dont want to steal it.

that kind of spamming will be really popular in future. If you add some text to each transaction and send it, it will works same as email spam

There is no law, no punishment for doing this. There are only consensus rules and mining policy in bitcoin. So, in this case right=ability. These are different apples.

Each such transaction costs 0.00045 for dishonest attacker (can be even less) 88 transactions (attack one block) will cost only 0.0396 BTC Daily attack 5.7024 BTC - not a big deal Wanna hire me for this dirty job? Main "weakness" for this attack is that miners could easily just ignore those transactions, without involving any hard fork. Only the pools that accept those transactions *and* that do not prioritize transactions in a block by total fee would be impacted, pools that build their blocks based on max fee they can rack in a block would automatically eliminate them, they may just need to take the SIGOPS limit into their block optimization code, but that's all. In practice only the "faucet pools", those that accept zero-fee tx and do not prioritize tx would likely feel the attack. So the practical spamming would be limited to relaying and the mempool, so no biggy. Yes this is right...once problem is identified it is easy for miners to ignore and fix the attack.

I would like to thank those that have (re)discovered this attack and shown it to be a viable attack using their own money to prove it.
Is anyone planning a large scale attack using this method? That would be interesting.
How much would it take to fund a sustained attack, for example a 24 hour period?

Our family was terrorized by Homeland Security. Read all about it here: http://www.jmwagner.com/ and http://www.burtw.com/ Any donations to help us recover from the $300,000 in legal fees and forced donations to the Federal Asset Forfeiture slush fund are greatly appreciated!

I think it is not ethical to do this attack, but also interested to know these answers for security purpose.
