When making a transaction with Bitcoin, we send the transaction to the miner’s network. To maintain that no one can make transactions using our wallet without being noticed, some security is put in place.
Bitcoin transactions occur between two or more wallets. As explained earlier, these two wallets are only public/private key pairs that are used to encrypt data. The way these two key pairs of work ensures that all data encrypted with a public key can be read with a private key, and vice versa.

In Bitcoin, we don’t have heaps of money that can go up and down like in a bank. Instead, we have a collection of Bitcoin that can be traced to its first miner. When making a transaction, we must reference the transaction when getting the Bitcoin (can refer more than one). Next, we must digitally mark each referenced transaction. That is, we have the details of the transaction and encrypt it with the private key. Because the public key will always be connected to our address (also the referenced transaction), it will be ensured that only we have the authorization to carry out the transaction.
Note that no physical data comes out of the wallet other than messages to the blockchain. The amount of Bitcoin in a wallet is calculated by looking at transactions in the blockchain. This means that anyone can check the amount of Bitcoin in any wallet. However, that does not mean that anyone can find out who has a particular wallet because it is not easy to determine the owner of each wallet.
When this transaction reaches the miner’s hand, the transaction is added to the next block. As we have understood that each blockchain can be subdivided (and a miner with large computing power can share it on an ongoing basis). There is no guarantee the transaction will enter the blockchain directly, but judging by the number of blocks available. If there is only one block, then a lucky attacker can disrupt the entire mining network. With more blocks coming into the blockchain, the work of the attacker will be more and more difficult.
Six blocks are usually considered sufficient to ensure that a transaction is properly added to the blockchain. At the rate of one block every ten minutes, the process of adding transactions can occur within one hour. For large nominal transactions, you may wait a little longer before the transaction has been transferred.
