The sender uses this information to construct a valid notification Bitmessage address:
# Use the recipient's 0<sup>th</sup> public key as the Bitmessage signing key: <pre>B</pre>
# Derive a Bitmessage signing key as: <pre>B = payment code / 0 / 0</pre>
# Initialize a counter at 1: <pre>n</pre>
# Derive a candidate encryption key: <pre>B' = B + nG</pre>
