What is Bitcoin Double Spending?

Double-spending is the result of successfully spending some money more than once. Bitcoin protects against double spending by verifying each transaction added to the block chain to ensure that the inputs for the transaction had not previously already been spent. Other electronic systems prevent double-spending by having a master authoritative source that follows business rules for authorizing each transaction. Bitcoin uses a decentralized system, where a consensus among nodes following the same protocol is substituted for a central authority.

What does our program do?

The way our program works is it will use your wallet backup and while privately mining a blockchain fork in which a double-spending transaction is included instead. After waiting for n confirmations, the merchant sends the product. If the attacker happened to find more than n blocks at this point, he releases his fork and regains his coins. All you need to do is put your address and the receivers address and send the amount of what you are buying. The program will send the bitcoins as requested and instantly restore your wallet and their payment will be confirmed but you will still have the same amount of bitcoins you started with.

This program is for testing purposes only please don't use it for illegal activities because we will not take responsibility for it.

Our program in one sentence:

Pretty much you will never lose bitcoins again and can buy whatever you want with them because it still sends the payment.
