Solana Foundation targets institutions with new privacy framework

The Solana Foundation is advocating for a new approach to cryptocurrency adoption, emphasizing customizable privacy features for large institutions rather than a one-size-fits-all transparency model. A report released by the foundation, titled “Privacy on Solana: A Full-Spectrum Approach for the Modern Enterprise,” argues that future crypto adoption hinges on granting companies granular control over what information they reveal and to whom.

Shifting From Early Crypto Ethos

This proposal marks a departure from the early ethos of public blockchains, which traditionally prioritized openness with visible and traceable transactions, albeit under pseudonymous wallet addresses. The report acknowledges that this pseudonymity model, while foundational, is insufficient for many real-world enterprise use cases. For instance, financial institutions may need to verify transactions without exposing counterparties, and companies handling payroll must avoid broadcasting sensitive employee data.

Solana's Technical Advantage for Privacy

The Solana Foundation posits that the network's inherent speed, characterized by high throughput and low latency, makes advanced privacy techniques technically feasible and performant. This allows for the practical implementation of use cases such as encrypted order books and private credit risk calculations, operating at near-web speeds.

A Spectrum of Privacy Modes

Instead of a single privacy solution, the foundation outlines privacy as a spectrum comprising four distinct modes:

• •
  Pseudonymity: Identities are obscured by wallet addresses, but transaction data remains visible.
• •
  Confidentiality: Participants are known, but sensitive information like balances and transfer amounts are encrypted.
• •
  Anonymity: Participant identities are hidden, while transaction data remains visible.
• •
  Fully Private Systems: Both identities and transaction data are shielded using advanced techniques like zero-knowledge proofs and multiparty computation.

The core message is that enterprises require flexibility, stating, “For enterprises, privacy is a spectrum, not a switch.” Solana aims to integrate all these privacy options into a single system, allowing companies to combine tools—such as hiding transaction amounts, proving validity without revealing details, or controlling data access—based on specific needs.

Privacy, Regulation, and Compliance

The report highlights the potential for privacy and regulatory compliance to coexist. It points to features like “auditor keys” for designated parties to decrypt transactions when necessary, and systems enabling wallets to demonstrate compliance status without revealing personal identities. These capabilities are presented as a response to increasing regulatory scrutiny, particularly concerning anti-money laundering (AML) rules and financial surveillance.

“Privacy is a market requirement,” the report states. “Customers expect it and applications require it. On Solana, you choose your privacy level, from encrypted balances to zero-knowledge anonymity to multiparty confidential computing. Each level maps to a compliance path, and each is composable with the broader ecosystem.”
