According to the chief economist of the Swiss National Bank Carlos Lenz (Carlos Lenz), the decentralized nature of blockchain is ill-suited for government-controlled digital currencies.
Lenz stressed, that blockchain is not very efficient, when it comes to centralized digital currencies. When designing state cryptocurrencies, various techniques are possible, including platforms using blockchain.
“When creating a digital frank, you can make a system with direct accounts in the National Bank. I will not say, that this is the best option, But he is the easiest. Or use a blockchain, But I don't think, that a decentralized solution will be perfect ", - said the economist.
Lenz also emphasized, that so far the Central Bank of Switzerland does not plan to really develop digital franc, since the existing payment system "works well". There is simply no need for state cryptocurrency in Switzerland.
Despite, that there are no plans to launch a digital franc yet, Recently, the Central Bank of Switzerland and France launched the experimental project “Project Jura” to test state digital currencies for international payments.
About that, that state cryptocurrencies do not need blockchain at all, More in 2019 a cryptocurrency skeptic Nuriel Rubini spoke a year (Nouriel Roubini).
