Abstract: Embodiments of the present invention are a system for recording the ownership of an electronic token and its corresponding interest-bearing instruments (referred to as Notes). The system automatically credits the face value of Notes to their holder's account on the scheduled maturity date, thereby precluding the possibility of default. The method of issuing the Notes is such as to ensure that the total quantity of tokens in existence cannot exceed its pre-determined limit at any future date. The present invention enables a blockchain system to have a risk-free interest-bearing instrument denominated in its token, in a way which is compatible with a pre-determined token supply.
