Philippe AGHION describes this publication as a “reference book for understanding the issues and threats of crypto-assets…”.
The book has twofold originality: – that of a duo of authors (which is not the most common in the field…), a duo of economists whose talent is well established, – but also, a parental duo, uniting mother and daughter around the crossed gazes of two generations that are both complementary and have different research and operational experiences.
This is one of the great riches and merits of this shared work. Thus, structured answers are proposed to the many questions that professionals and non-initiates ask themselves about the “ecosystem of crypto-assets”. Clearly emerging as one of the major technological innovations in the world of payments, these crypto-assets are wrongly qualified as “currency” (they only very partially fulfill the three main functions of a currency: instrument of exchange, unit of account, store of value), but they have given birth to a new model of finance, “decentralized finance” (Defi). They seem de facto, as the authors point out, to open: “a ‘new currency war’ between official currencies and private digital currencies, a perspective that cannot leave Central Banks indifferent: ‘it is a change of monetary and financial paradigm'”. The authors strive to make this transparent by developing four main questions:
– The genesis of crypto-assets and the blockchain
– decentralized finance and crypto-assets, – the currency war in the digital age, and – the analysis of the threats to financial stability of these digital developments.
At a time when the new President of the United States is initiating a spectacular “pro-crypto” turnaround, this publication, which is illustrated by analyses accessible to a wide audience, will undoubtedly appear to be a decisive contribution to the understanding of this sensitive subject, the risks of which remain largely underestimated.
