In addition, the crypto ecosystem inherits and may amplify the vulnerabilities of the mainstream financial system, as it grows and tries to replicate the functions of that system, and it introduces new points of vulnerability like bridges between blockchains or so called oracles that feed data to blockchains. Third, the investigations undertaken by many central banks, for the issuance of a retail and/or a wholesale CBDC, should be seen in my view as part of a broader response by central banks, in line with their monetary and financial stability mandate, to help bring the financial landscape, which will result from those transformations, within a confidence prone regulatory and operational framework, to help reap their benefits and master their risks. At the Banque de France, our response is based on three convictions: First, the traditional pillars to ensure confidence cannot be replaced by any "algorithmic" confidence, namely by rules of the game that would be coded once and for all and for which respect would be entrusted to algorithms. Second, confidence requires a regulatory framework that is clear, fair ("same business, same risk, same rule"), balanced and consistent at international level, if we want to simultaneously encourage innovation, protect adequately customers and investors, and maintain the stability of our financial system. Europe has led the way in this field, with the adoption of MiCA.
