Privacy Enhancing Tools

Definition

Privacy enhancing tools are technologies designed to protect user anonymity and data confidentiality in digital transactions. In the cryptocurrency domain, these tools include protocols like zero-knowledge proofs, mixers, and privacy coins, which obfuscate transaction details such as sender, recipient, or amount. Their purpose is to prevent the public traceability inherent in many blockchain networks, offering users greater control over their financial data. These solutions address concerns about surveillance and data aggregation.
