You have a Bitcoinhis was not sent to anyone.
After confirming this information, the transaction is included in a block attached to another block. The name block string is used, all transactions cannot be canceled or modified, all other blocks can be disturbed.
Some additional complications-
Sometimes the Bitcoin portfolio does not hold a bitcoin. He holds the Bitcoin address several times. All transaction records are at this address. The address – is a long chain of 34 letters. It is called the public key that everyone can see. Each key/public address has a respective “private key” that has 64 letters and numbers. It must be kept safe and safe. These 2 keys are connected, but in any way we can’t distinguish the keys.
Every transaction issued from your Bitcoin address must be linked to the private key and signed thereby. The private key and the details of the transaction are required. How many bitcoins should be sent and what account all this information is stored.
As a result of this information, a digital signature is created, which is sent for validation. This transaction is then validated – it is confirmed that I have a Bitcoin and that the transfer is made.
Use the signature and the public key known by everyone? If the signature is made using the private key matching the public key, the program will then confirm the transaction, even if the private key is not known.
The network ensures that Bitcoin is not already spent by checking the address history. As he knows the address that is nothing but the public key.
Even more complicated:
Once your transaction validation occurs, it is included in a block with other blocks of blocks.
We must discuss what a hash; A hash is manufactured by a hash function. This is a mathematical equation that converts any amount of text or 64 character data. When filling in this data through the hash feature, we get the same chain of 64 characters. But even if a slight change occurs, we will receive a completely different set of the 64-bit data chain. In this way we can say if something has changed and that is the way a blockchain can confirm whether the data is disturbed.
This is what Bitcoin makes so that it cannot be changed or disturbed. There is much less chance to play.
You can invest in Bitcoin by visiting the commercial area, so you know the options through which it can be done.
