MOD EDIT:
Pretty sure this guy is just trolling.  OP if you edit or remove this I'm banning you.




Hello Folks,

I know this is a provoking title. I am working as a researcher at a european university and i have already dedicated many years of my life to revealing insecurities in bitcoin.
My first stept were to solve thy mythos about the fact that nvidia cards are slower than ATI cards due to a missing right rotate function. This is crap resulting from not so good developers: I have showed how to implement sha256 without using right rotations and speeded up nvidia bitcoin mining by factor 3. Additionally an extra speedup has been made by guessing if the hash will be a leading-zero one or not with over 80% probability 5 sha rounds ahead. A very welcome extra speedup.

Enhancing Bitcoin mining was not satisfying me however. I wanted to go more over the top so i started on revealing other security holes.
This for example involved finding low quality transaction signatures with weak random seed values and exploiting the signature algorithm to reveal the private keys via simple XOR operations.

Right now I am working on another attack by revealing bitcoin adresses incl. their private keys. Several "super brains" in here keep telling you that it is almost impossible to guess the right private key because there are as many possibilities as atoms in the universe. Blah blah blah, just some wanna be script kiddies repeating what the read somewere on the IRC channel. Here you get a couple Bitcoin Adresses and their Private Keys that i have found in the last 2 hours. Good collision rate, huh? Eventually we will find an account with several million $$$ in it.

If anyone wants to support my work so i can make it open source (all, also the nvidia miner kernels) feel free to donate to:
NOPE

If you want my hacking ideas and proof of concept scripts, just send me 10 BTC and contact me on PN:

I think he will find it much easier to hack bitcoin than to get anyone here to send him any BTC.   Cheesy

Asking for donations, and asking for 10 BTC to reveal his super-secret hacking methods...

Get the fuck out of here.  If Bitcoin was truly this insecure, you wouldn't be asking for BTC that would be worthless if you were actually cracking private addresses.  This would mean Bitcoin would be tanking soon, to oblivion, and your 10 BTC from every sucker who fell for it would be worth the dirt under your feet.

Lets see a proof of concept.
I give you full authorization to break into the wallet on my phone. Please post my private key.
Address 1BgnX3rwyK9DzJHSuYPw2Kv9Zn73RxGiZ8

If you want proof that it is mine. Just ask. I can take a pic with it up on my phone.

Maybe I'm missing something (and admittedly I may be) but what exactly does listing wallet addresses and private keys prove? I can create a bunch of wallets and list their addresses and private keys too. How do we know you didn't create those wallets? It's sort of a which came first, the chicken or the egg thing. If you are able to derive a private key from a wallet address, why are you only wallets that have had ~0.1 BTC or less in them? It seems more likely that you have created those wallets or are randomly generating addresses and then checking to see if they've had activity. In that case, you'll probably find that mining is more lucrative.

Also, if you have improved Nvidia mining by a factor of 3, write a Nvidia miner. There will be a line of people waiting to donate to you then.

It might just prove that there is a sucker born every minute, even on the bitcointalk.org forum.

"The powers of financial capitalism had another far-reaching aim, nothing less than to create a world system of financial control in private hands able to dominate the political system of each country and the economy of the world as a whole. This system was to be controlled in a feudalist fashion by the central banks of the world acting in concert, by secret agreements arrived at in frequent meetings and conferences. The apex of the systems was to be the Bank for International Settlements in Basel, Switzerland, a private bank owned and controlled by the world's central banks which were themselves private corporations. Each central bank...sought to dominate its government by its ability to control Treasury loans, to manipulate foreign exchanges, to influence the level of economic activity in the country, and to influence cooperative politicians by subsequent economic rewards in the business world."

That is why I asked him to post my private key. It is an address I do not care about. So, lets see if he can do it.

Asking for 10BTC without any proof whatsoever? You have 2 posts and you registered yesterday.

Don't waste the forum's bandwidth, scammer.

How about you sign a message with the private key of one of the top 10 bitcoin balances?

Then we might be inclined to believe you. But then again, if you have access to over 100,000 in BTC - why do you need us to do anything at all?

If he is just "cracking" brain wallets I have a bitaddress.org file that I modified to check wallet balances and activity, so you can check word lists or randomly generated addresses. When it finds a balance (or activity) it will notify you. It's javascript so not the fastest method, but it works and is all contained in one file. I modified it when someone on reddit posted a challenge to break in and steal 1 BTC from each of their 5 brain wallets that had weak passphrases. I found out about it the day before it ended and didn't end up getting into any of them.

I'll undercut IHackedBitcoin and sell it for the low, low price of a 8 BTC donation.  Wink
