What Privacy Features Do Quantum-Resistant Wallets Have?

Quantum-resistant wallets can integrate privacy-preserving features that protect transaction details from public observation. These features, combined with post-quantum cryptography, ensure that privacy protections remain effective against both classical surveillance and quantum computing capabilities.

Confidential transactions encrypt transaction amounts while allowing network verification of validity. The blockchain records that a valid transaction occurred without revealing the value transferred. Mathematical proofs (typically range proofs) demonstrate that amounts are non-negative and balance correctly without exposing actual values.

Stealth addresses generate unique one-time addresses for each received payment. The sender creates a transaction to a derived address that only the recipient can identify and spend from. Public observers cannot link multiple payments to a single recipient even when the same public address is shared.

Ring signatures or similar constructions can obscure the true sender among a group of potential signers. Verifiers confirm that one of the ring members signed the transaction without identifying which one, providing sender anonymity.

Quantum resistance for these privacy features requires post-quantum implementations. Traditional privacy schemes often rely on ECDSA or similar vulnerable cryptography. Quantum-resistant versions use lattice or hash-based constructions to maintain privacy guarantees against quantum-capable adversaries.

Privacy features involve trade-offs. Larger transaction sizes, increased computational requirements, and potential regulatory scrutiny accompany enhanced privacy. Users select features appropriate for their use case.

SynX integrates privacy features with Kyber-768 and SPHINCS+ quantum resistance. Transaction amounts and participant identities benefit from built-in protection, ensuring financial privacy remains intact as computational capabilities advance.
