The Logic of Money: Crypto Mechanics and the Limits of Tokenisation

Cryptocurrencies are widely recognised for catalysing distributed ledger technologies and tokenisation, innovations that are transforming payment systems globally. However, their role as money is often contested and the subject of intense academic and policy debate. Nevertheless, new taxonomies of money allocate a unique place for cryptocurrencies. Described based upon a few high-level features, cryptocurrencies, except for stablecoins, are assumed to be a uniform group that can indeed be studied and categorised as such. Moreover, the logic of their creation is often looked at from a broad decentralisation and disintermediation perspective and remains ambiguous and questionable at best. This paper reports the findings of a clinical investigation into the top 30 cryptocurrencies representing 95.5% of the total crypto market capitalisation. This study is primarily concerned with their logic of creation, and how they compare with that of fiat money and central bank digital currencies. The findings reveal that, unlike fiat money, and CBDCs, crypto mechanics depict a diverse assortment of logics. The evidence suggests that despite widespread technical innovations, the crypto ambition to provide an alternative to centrally controlled debt-based fiat money has managed to add a combination of transaction validation, mathematical guesswork, pseudo-randomness, and size dependent probability as alternative logics of creation and allocation. While centrally managed bank-controlled debt-based fiat money leaves a lot to be desired, protocol-managed, code-controlled, size-dependent probabilistic money does not seem like much of an upgrade. This paper addresses the limits of tokenisation as a transformational tool and argues that cryptocurrencies may have helped trigger improvements in the technology of money, but not in its logic of creation. Indeed, to compete in the emerging monetary landscape it has helped create, i.e., the ubiquitous tokenisation of debt and debt-based fiat money, the crypto revolution will have to extend its value proposition beyond technology and pseudo-randomness.
