“Programmable money” is, without doubt, one of the major buzzwords in the blockchain space in 2020. Even though everyone seems to talk about it, we still lack a clear definition and hence common understanding of this term. In this article, we present a taxonomy of programmable money. In particular, we argue that “programmable money” has to be differentiated from “programmable payments”. To make this distinction as clear as possible, we develop a framework in which we decompose the payments value chain into three pillars: the contract execution system, the digital payment infrastructure, and the monetary unit.

Programmable payments

The terms “programmable money” and “programmable payments” are often used interchangeably, even though they mean different things. Programmable payments are payments that are automatically executed after certain conditions are met. Thus, these payments are automated and follow an inherent, predetermined logic. Programmable payments already exist in today’s banking system, for example, in the form of standing orders and direct debits.

However, it is difficult to implement complex logic into these payments and hence their flexibility is limited. In this context, smart contracts based on distributed ledger technology (DLT) offer more degrees of freedom. With the help of smart contracts, even complex business processes can embed automated payments.

For instance, in the Economy of Things (EoT), autonomous e-cars will drive to the next charging station, negotiate a price, carry out the charging process and then make a payment. The payment will be split directly and transferred to all stakeholders according to a predefined key (e.g., 70% to the electricity provider and 10% each to the charging station manufacturer, the gas station operator, and the car manufacturer). This payment is managed by a smart contract and is therefore automated and programmed.

Three key features of smart contracts

To clarify the understanding of smart contracts, we rely on how smart contracts are realized on the Ethereum platform. In short, such smart contracts mainly have the following three features:

1st feature of smart contracts: programming capabilities. Smart contracts enable programmable payments triggered by arbitrary…
