Solana Foundation Proposes Flexible Privacy Framework to Drive Enterprise Adoption

The Solana Foundation released a report on March 23, 2026, arguing that enterprise adoption of blockchain technology requires customizable privacy controls rather than a one-size-fits-all model, positioning Solana’s high throughput as enabling advanced privacy techniques such as zero-knowledge proofs (ZKPs) while maintaining regulatory compliance capabilities.

The report, titled “Privacy on Solana: A Full-Spectrum Approach for the Modern Enterprise,” outlined four distinct privacy modes—pseudonymity, confidentiality, anonymity, and fully private systems—and argued that the next phase of crypto adoption depends on giving companies control over what information they reveal and to whom. The framework is designed to allow institutions to mix and match privacy tools based on specific use cases, from encrypted order books to private credit risk calculations.

Privacy as a Spectrum, Not a Switch

Four Privacy Modes

The report presents privacy as a spectrum with four distinct levels:

Pseudonymity: Identities are obscured behind wallet addresses while transaction data remains visible—the traditional public blockchain model

Confidentiality: Participants may be known, but sensitive information such as balances and transfer amounts is encrypted

Anonymity: Identities of participants are hidden while transaction data remains visible

Fully private systems: Both identities and transaction data are shielded using zero-knowledge proofs and multiparty computation

The foundation emphasized that no single privacy model fits all enterprise use cases, stating: “For enterprises, privacy is a spectrum, not a switch.”

Composability Across Privacy Levels

Rather than requiring companies to choose a single privacy approach, Solana’s framework allows organizations to mix and match tools based on specific requirements. The report gave examples including:

• Executing trades without revealing order size

• Sharing risk data across banks without exposing individual balance sheets

• Allowing users to prove compliance without disclosing personal information

Technical Foundation: Solana’s Speed Enables Advanced Privacy

Performance as Enabler

The report argued that Solana’s high throughput and low latency make advanced privacy techniques practical at scale, allowing these methods to run at near-web speeds. This technical capability opens the door to use cases that would be impractical on slower networks, including encrypted order books and private credit risk calculations.

Zero-Knowledge Proofs and Multiparty Computation

The framework leverages zero-knowledge proofs (ZKPs) and multiparty computation (MPC) as core technologies for fully private systems, enabling verification of information without revealing the underlying data. These techniques allow participants to prove transaction validity, compliance, or creditworthiness without exposing sensitive details.

Privacy and Regulation: Coexistence Framework

Auditor Keys and Compliance Mechanisms

The report emphasized that privacy and regulation can coexist through built-in compliance features. One mechanism highlighted is “auditor keys,” which enable designated parties to decrypt transactions when required for regulatory review or investigations. Other systems would allow wallets to demonstrate compliance status without revealing identity—a capability particularly relevant for anti-money laundering (AML) rules and financial surveillance requirements.

Market Requirement

The foundation framed privacy not as an optional feature but as a market requirement: “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.”

Strategic Context

Institutional Adoption Hurdles

The report acknowledges that traditional public blockchain transparency, while foundational, falls short for many real-world enterprise use cases. Financial institutions may need to prove transactions occurred without exposing counterparties, while companies processing payroll must avoid broadcasting employee salaries.

Regulatory Scrutiny

The framework positions customizable privacy as a response to growing regulatory scrutiny, particularly around anti-money laundering rules and financial surveillance. By allowing compliance mechanisms such as auditor keys while preserving privacy for routine transactions, Solana aims to address concerns that have historically limited institutional participation in public blockchains.

Frequently Asked Questions

What privacy options does Solana’s framework offer enterprises?

Solana’s framework offers four privacy modes along a spectrum: pseudonymity (identities hidden, transactions visible), confidentiality (participants known, data encrypted), anonymity (identities hidden, transactions visible), and fully private systems (both identities and data shielded). Companies can mix and match tools based on specific use cases.

How does Solana enable advanced privacy without sacrificing compliance?

The framework incorporates mechanisms such as “auditor keys” that allow designated parties to decrypt transactions when required for regulatory review. This enables compliance with anti-money laundering and financial surveillance requirements while maintaining privacy for routine operations.

Why is privacy becoming important for enterprise blockchain adoption?

Public blockchains traditionally emphasize transparency, where all transactions are visible and traceable. However, enterprises have legitimate privacy needs: financial institutions may need to prove transactions without exposing counterparties, and companies processing payroll must avoid broadcasting employee salaries. Solana’s framework aims to address these gaps while maintaining regulatory compliance capabilities.
