Imagine if your NFC acted as its own treasury and central bank, managing the supply and tenor of credit to produce a personal yield curve. This isn't a yield curve on your debt, but instead on your credit. Others could borrow using "prints" of your NFC for some borrowing period, where the yield they pay depends on how many "prints" are available at each tenor. The yield is paid to the original NFC owner, but you could sell this "print" of the NFC on secondary markets. In case you haven't made the connection, this pricing and yield functionality would be loosely based on the Euler Beats model.
