The Solana Foundation positions privacy as enterprise-customizable privacy levels, noting that the next wave of cryptocurrency adoption requires enterprises to control the data they disclose. In a recent report, the foundation outlined four privacy modes—ranging from anonymity to fully private systems using zero-knowledge proofs—which can be mixed and used within its network. The foundation claims that Solana's speed enables advanced technologies to be put into practical application, and emphasizes that features such as "audit keys" allow privacy and regulatory compliance to be balanced, applicable to use cases such as private transactions or confidential risk calculations.
