The Double Spending Problem and Cryptocurrencies

Abstract

The aim of this chapter is to situate blockchain-based governance tools within a public value (PV) context, arguing that public governance on the blockchain requires elements of a “public value mindset,” which is comprised of transparency, efficiency, stakeholder salience and participation, innovative thinking, decentralization, and trust. To illustrate this PV mindset, the chapter analogizes the powerful solution put forth by cryptocurrencies towards the “double spending problem,” an issue that had once plagued electronic money, by arguing that the manner in which the double-spending problem was solved by blockchain technology (as best embodied by cryptocurrencies) also offers lessons for public governance on the blockchain, specifically in terms of the PV elements enumerated above. By elucidating the nature of the double-spending problem and the revolutionary solution offered by cryptocurrencies, the chapter advocates for a similar approach in the application of blockchain technologies to public management and governance.
