Is it true that a Bitcoin transaction can only be signed on a machine connected to the Bitcoin network?

True
False
Only if using a wallet
Only if remote signing

The correct answer is: False

A Bitcoin transaction does not need to be signed on a machine directly connected to the Bitcoin network. The signing process involves cryptographic operations that can occur offline, using a private key stored securely on a device that does not connect to the internet. This is often referred to as "cold storage" or "cold wallets," where the transaction can be created and signed offline, enhancing security against potential online threats. Once the transaction is signed, it can then be transmitted to the Bitcoin network from any device that is online, making it possible to send transactions without being constantly connected. This is crucial for maintaining the security of one's private keys, as exposing them to an online environment increases the risk of theft or compromise. The other options suggest limitations that are not required, such as needing a wallet or a specific type of signing, which do not capture the flexibility offered by Bitcoin’s transaction signing process.
