hello i am a hirosika and i am mechanic engineer.

I tested a bitcoin wallets and i found a security weakness.

i copy wallet with a modified code.

normally, other net hash denied fake coin remittance, but i make a forced admission with closed fake net hash.

and i succeed deposit to exchanges my fake coin.

i will do not open this method to the public but i think some crackers already knew this way.

i am not used an english so i am immature. sorry about that.

well...i think bitcoin need a softfork.

how i contact bitcoin developer?

I don't understand the nature of the vulnerability, but if you found a security issue in Bitcoin Core wallet, you can contact them at security@bitcoincore.org

Otherwise, the problem might be in the exchanges you were using, so you should contact them.

I'm sure Development & Technical Discussion section is good place to talk about this problem. Also, bitcoin core isn't the only bitcoin developer.

I call bullshit on this one, such vulnerability of faking coins can not be broadcasted on the Bitcoin Network, if I am understanding what he's saying.

You can submit the bug here: https://github.com/bitcoin/bitcoin

That might a security flaw from the exchange, or are you able to send 'fake bitcoins' to other wallet?

there hasn't been a flaw like this for many years, can you post transactions that show this?

i guess you are on testnet mode .

because you cant just make coins out of nowhere, i mean such coins only come from mining.

and only inputs can be outputs.


send 1000 bitcoins to my wallet 14jp1tXiXbWJE8pxXR9oPhv7kQZqMWZddK
and PM me your paypal address.

I bet 1 BTC, that OP's fake transaction "with closed fake net hash" has no more than 0 confirmations.

Haha, it's unfortunate that Op didn't mention about txid from his cracked wallet to exchange but he stated it works which mean it has more than 0 confirmations. Well, I am not sure about his fake coins but at least he tried to contact core developers.
I am wondering how is it going, whether this problem really serious as a leak in blockchain system or not.
