From Capabilities To Financial Instruments

From Capabilities To Financial Instruments

A major aspect of the emergence of capitalism from feudalism was the rise of contract. By creating a contract, you could define and transfer an arbitrary bundle of rights. The complexity of trade could now bloom, unrestrained by the simple limits of physical matter. During the twentieth century, a great variety of financial instruments were invented. These instruments represent the discovery of many new kinds of rights, and ways of deriving these rights from more primitive rights. We should hope the growth of financial cryptography will only accelerate this trend. For this hope to be realized, we should seek not just the secure computational expression of the contracts representing existing instruments, but the creation of secure material from which similar new contracts can easily be built. Following Nick Szabo [Szabo97], we refer to a partially self-enforcing computational embodiment of a contract as a smart contract.
