New Fordham International Law Journal article by Hub researchers offers a complete taxonomy of currencies

Hub researchers Anton Didenko & Ross Buckley propose in their new article a comprehensive taxonomy of existing currency types used in different types of modern payment systems

No agreed taxonomy covering the entire range of currencies used in modern payment systems exists today, which can be explained by the rapid pace of technological innovation. In their article ‘The Evolution of Currency: Cash to Cryptos to Sovereign Digital Currencies’ published in the Fordham International Law Journal Allens Hub researchers Anton Didenko and Ross Buckley propose a comprehensive taxonomy of existing currency types, from seashells (still used by some Pacific nations) and community currencies (like the Bristol Pound) to Bitcoin and sovereign digital currencies. In doing so, they aim to eliminate the confusion caused by the emergence of new technologies that has spawned numerous conflicting terms (which are often used interchangeably): ‘electronic money’, ‘cryptocurrencies’, ‘virtual money’, ‘digital currency’ and many other variations.
