Melon ([méllō], μέλλω; Greek for "destined to be") is blockchain software that seeks to enable participants to set up, manage and invest in technology regulated investment funds in a way that reduces barriers to entry, while minimizing the requirements for trust. It does so by leveraging the fact that digital assets on distributed quasi-Turing Complete machines can be held solely by smart-contract code, and spent only according to preprogrammed rules within this code. The Melon protocol is a set of rules for how digital assets can be spent once held in a Melon smart-contract, or a Melon investment fund. These rules are meant to protect the investor and fund manager from malevolent behaviour of each other, even when both parties remain private. Melon is to investment funds as Bitcoin is to accounting: a set of rules, enforced by blockchain technology, legitimized by the consent of its participants.
