[New Privacy Framework for Institutions Introduced by Solana Foundation] According to CoinDesk, the Solana Foundation has released a report titled *'Privacy on Solana: A Comprehensive Approach for Modern Enterprises'*, proposing that enterprise adoption requires flexible privacy controls and positioning privacy as a customizable feature rather than a trade-off. The report suggests that the next phase of crypto adoption will depend more on enabling enterprises to control who sees what information, rather than solely relying on transparency. The Solana Foundation outlines four distinct privacy models: pseudonymity, confidentiality, anonymity, and fully private systems. Pseudonymity hides identities while keeping transaction data visible; confidentiality allows participants to be known but encrypts sensitive information; anonymity hides participant identities while keeping transaction data visible; fully private systems use technologies like zero-knowledge proofs and multi-party computation to obscure both identities and transaction data. The report emphasizes that no single privacy model fits all scenarios, and enterprises can mix and match different tools based on their needs. The report highlights that Solana's high throughput and low latency enable advanced privacy technologies to operate at near-network speeds, making applications like encrypted order books or private credit risk calculations feasible. The Solana Foundation also proposes mechanisms like 'audit keys,' which allow designated parties to decrypt transactions when necessary, achieving a balance between privacy and regulatory compliance.
