BIP47 PayNyms (privacy view)

Privacy-oriented summary; full details in ../../wallets/payment-codes/SKILL.md.

Privacy properties

  • Sender has anonymity-of-1 — server can correlate "X paid Y" via notification tx.
  • Receiver public address never appears on chain.
  • Different sender pairs use different derivation chains → no cross-sender correlation.

Compared to Silent Payments

  • BIP47 has notification tx that leaks the existence of sender ↔ receiver pairs.
  • Silent Payments has no notification tx — better privacy.
  • BIP47 has lower scan cost for receiver.

Status

  • Sparrow + Stack Wallet maintain BIP47 support.
  • Samourai (formerly the dominant BIP47 wallet) shut down 2024.
  • Adoption in decline as Silent Payments matures.
