Bitcoin Q&A: What are PayNyms?
What are PayNyms / BIP-47 reusable payment codes and how do they work? A payment code for hierarchical deterministic wallets, which can be publicly advertised and associated with a real-life identity without creating the loss of security or privacy inherent to P2PKH address reuse. They are supported natively by Samourai Wallet.
