A Universal Quotient of Banking APIs

The Takeaway
We think of 'money' as a messy mix of local laws and different technologies. By analyzing nearly 5,000 banking APIs, this paper found a 'universal structure' of value transfer. No matter the country or the currency, the way money moves is governed by 14 'jurisdictionally invariant dimensions.' This means that finance isn't just a social construct; it’s a universal mathematical grammar that exists independently of human politics. It’s as if the 'physics of money' was discovered hidden inside the code of our banking apps.
From the abstract
Four axioms of immutable ledger, linear consent, payment irreversibility, and bounded credit manifest themselves as institutional facts codified by banking practice for the transfer of monetary value. These axioms certify the independence of 14 empirically observed and jurisdictionally invariant dimensions. Morphisms of the ambient category do not admit sections that would reconstruct one dimension from another, and every morphism admits epi-mono factorisation through the universal quotient Q_pu
