Traditional payments rely on banks and other centralized institutions to store information and ensure security, while crypto payments are decentralized and have public ledgers, with users managing their own private keys.

Privacy protocols use technologies such as zero-knowledge proofs to protect KYC information and card numbers, preventing the association of addresses with identities, guarding against data leaks and theft. They also provide clear accountability paths, which is a key difference from traditional payments and essential for maintaining security.
