Transaction anonymity refers to the degree to which the participants and details of a digital asset transaction are obscured from public view. While many blockchains offer pseudonymity, where addresses are public but not directly linked to real-world identities, true anonymity seeks to break these links. This is achieved through various cryptographic techniques like zero-knowledge proofs or coin mixing.
