This link contains an RFC for a new type of Bitcoin address called a
"payment code"


Payment codes are SPV-friendly alternatives to DarkWallet-style stealth
addresses which provide useful features such as positively identifying
senders to recipients and automatically providing for transaction refunds.


Payment codes can be publicly advertised and associated with a real-life
identity without causing a loss of financial privacy.


Compared to stealth addresses, payment codes require less blockchain data
storage.


Payment codes require 65 bytes of OP_RETURN data per sender-recipient pair,
while stealth addresses require 40 bytes per transaction.
