How Privacy works

Privacy is a privacy protocol designed for Solana. Shielded asset records, zero-knowledge proofs and post-quantum cryptography form the foundation for private transfers and selective disclosure, while users retain control of their keys.

Private notes. Solana settlement.

A private note represents an asset, an amount and its owner. Commitments let the protocol verify state without publishing the underlying details.

Designed for the quantum era.

Public blockchain data can be stored today and analyzed in the future. Privacy is designed around quantum-resistant privacy to reduce that long-term exposure.

Built for long-term privacy

Balances and paymentsHash-based commitments and post-quantum encryption are the foundation of the protocol design.

Who paid whomPrivate ownership and spend proofs are designed to avoid exposing a direct link to your public wallet.

Which payments are yoursPrivate payment discovery is designed to let recipients identify transfers without revealing them publicly.

Your proofsZero-knowledge proofs are designed to verify validity while revealing only the required statement.

Self-custodial. Always in your control.

Keep signing keys under your control. The protocol is designed to verify authorized transfers through proofs rather than public account details.

Use Solana privately. Disclose on your terms.

A privacy layer designed for Solana applications, with shielded balances, private transfers and disclosure controlled by the user.

Selective Disclosure

Selective disclosure lets users prove specific statements about shielded activity. Policies define what may be revealed, to whom, and with whose approval.

Verifiable, selective disclosure.

Approve a focused request and share the proof that matters, while keeping unrelated balances and activity private.
