Privacy has emerged as a critical requirement for institutional adoption of cryptocurrencies, according to Mixin CMO Sonny Liu. As the digital asset market transitions from speculative trading to a mature financial framework, privacy is no longer just a feature but a necessity for large-scale economic activity. Liu argues that the transparency of early blockchains, once seen as an asset, now poses a security risk as crypto handles more significant financial transactions. The shift towards privacy became evident in late 2025, with increased interest in privacy coins and Grayscale launching a privacy coin-based investment product. Liu emphasizes that privacy is foundational for secure and compliant financial infrastructure, allowing for regulatory alignment without compromising confidentiality. Mixin employs CryptoNote technology and a dual-key structure to ensure transaction privacy while enabling selective audits, addressing the balance between compliance and confidentiality.
