The Solana Foundation has launched a new privacy framework aimed at institutional clients, outlining flexible privacy levels for data sharing.
The Solana Foundation has unveiled a new privacy framework aimed at attracting institutional clients by offering a range of adaptable privacy options.
Privacy on Solana is a spectrum.
We just published our new enterprise report mapping pseudonymity, confidentiality, anonymity, and fully private computing. With compliance frameworks at every level.

The organization believes that future adoption of cryptocurrency relies not just on transparency but also on businesses' ability to control their data sharing practices.
Highlighting the limitations of pseudonymous models in public blockchains, the foundation pointed out that financial institutions often need to validate transactions without disclosing counterparties.
Understanding Privacy Levels
Rather than offering a singular privacy solution, the framework categorizes privacy into four distinct levels:
- Pseudonymity
- Confidentiality
- Anonymity
- Fully private systems
Pseudonymity masks identities behind wallet addresses while allowing transaction details to remain visible. In contrast, confidentiality maintains identifiable participants but encrypts sensitive data such as transaction amounts.
Anonymity keeps transaction parties concealed while still showing the transaction itself. Finally, fully private systems use techniques like zero-knowledge proofs and multi-party computation to secure identities and data.
Corporate clients can mix and match these options according to their specific requirements, according to the foundation.
“Privacy is what the market demands. Clients expect it, and so do applications,” stated representatives from the foundation.
The Solana Foundation also highlighted that the network's speed facilitates the implementation of these complex privacy solutions, enabling scenarios such as encrypted order books and private credit assessments.
In February, Solana introduced Solana Payments, a centralized platform for cryptocurrency transactions, further enhancing its service offerings.
