Bitcoin transactions are carried out through a decentralized network of computers. When someone wants to send Bitcoin to another person, they create a transaction message that includes the recipient's public key (Bitcoin address), the amount of Bitcoin being sent, and the sender's digital signature. This transaction is then broadcast to the network where it is verified by miners. Once the transaction is verified, it is added to a block and added to the blockchain. This entire process ensures that the transaction is secure, transparent, and irreversible.
