Stealth Address
Definition
A stealth address is a one-time address generated for each transaction, preventing address reuse and protecting recipient privacy. The sender creates a unique address from the recipient's public key; only the recipient can detect and spend the received funds. Post-quantum stealth addresses use quantum-resistant key derivation.
Technical Explanation
Stealth address protocols use Diffie-Hellman-like key exchange: the sender generates an ephemeral key pair, derives a shared secret with the recipient's public key, and creates a one-time address. The recipient scans transactions for addresses matching their key.
Post-quantum adaptation: classical ECDH is quantum-vulnerable. Kyber-based key encapsulation can establish the shared secret for stealth address derivation. The ephemeral Kyber exchange protects the one-time address generation against quantum attacks.
SynX Relevance
SynX supports stealth addresses using Kyber-768 for quantum-resistant key derivation. Each transaction creates a unique receiving address that only you can identify and spend. Blockchain observers cannot link transactions to your public identity.
Frequently Asked Questions
- Do I need new addresses for privacy?
- Stealth addresses generate them automatically—you share one stealth address; senders create unique payment addresses.
- How do I find payments to stealth addresses?
- Your wallet scans transactions using your private key to detect incoming payments.
- Are stealth addresses standard?
- Various implementations exist (Monero, EIP-5564); quantum-resistant versions are emerging.
