What defines a transaction in the Bitcoin network?

1. The amount of currency transferred

2. The digital signatures used

3. The addresses involved

4. All of the above

The correct answer is: All of the above

A transaction in the Bitcoin network is defined by several key components that work together to ensure the integrity and validity of the transaction. The selected answer, which includes all aspects of a transaction, reflects the comprehensive nature of how transactions are constructed and verified in the Bitcoin ecosystem. The amount of currency transferred is crucial as it specifies the value being exchanged between the parties involved in the transaction. This aspect ensures that the correct quantity of Bitcoin is sent from the sender's wallet to the recipient's wallet. Digital signatures play a fundamental role in securing transactions. They are generated using private keys and serve to verify the authenticity of the transaction, proving that the sender has authorized the transfer of the specified amount of Bitcoin. This cryptographic signature ensures that only the legitimate owner of the Bitcoins can initiate a transaction, thus maintaining security within the network. Addresses are vital as well, as they function as unique identifiers for the wallets involved in the transaction. Each Bitcoin address corresponds to a public key, and transactions are directed between these addresses. This not only facilitates the actual transfer but also ensures that the recipient can differentiate between various transactions. Together, these three components—the amount of currency transferred, the digital signatures, and the addresses involved—create a complete and secure representation of a Bitcoin transaction,
