Question

BlackTom AI · Accepted Answer

The question asks to identify which item is not a type of cryptography relevant to blockchain. 
Option 1: Asymmetric key cryptography. This is definitely relevant to blockchain, as the typical use is to generate public/private key pairs for digital signatures and address creation, enabling secure authentication and transaction validation. 
Option 2: Phishing Attacks. This is not a cryptographic technique; it’s a social engineering method used to trick users into revealing credentials or private keys. It falls outside the realm of cryptography itself and is more about attacker deception than cryptographic methods. 
Option 3: Symmetric key cryptography. While less prominent than asymmetric cryptography in many blockchain design aspects, symmetric cryptography can still play a role in certain protocols or off-chain communications where shared keys are used for confidentiality. It remains a cryptographic technique, so it is relevant to the broader field. 
Option 4: Digital signatures. Digital signatures rely on asymmetric cryptography to provide authentication, data integrity, and non-repudiation, and they are central to blockchain transaction verification and block validation. 
In summary, the only choice that is not a cryptographic type is Phishing Attacks, which is an attack vector rather than a cryptographic method.
