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.
