It argues that all functional +requirements laid out in the report can be fulfilled by operating the two systems +in parallel: +<ul> +<li>A bearer-based digital euro based on trusted hardware that can be used +offline, anonymously, and without third-party intervention. +<li>An account-based digital euro that can be used online, is fully software- +based and excludes the possibility of anonymity. +</ul> +The report does not discuss other choices of hybrid systems. However, the +choice is more arbitrary than it might seem at first sight: bearer-based systems +are not necessarily offline payment systems, and online payment systems do not +need to exclude anonymity. +</p> +<p> +We argue that operating a bearer-based payment system to complement an +account-based CBDC in order to gain offline and privacy features is not a good +trade-off. Adding permanent, regular offline capabilities via the bearer-based +payment instrument constantly exposes the CBDC to the severe issues inherent +in offline-capable payment systems. Instead, the offline mode of operation +should be restricted to scenarios where it is actually required, which mitigates +the risks. +</p> +<h4>Download links</h4> +<ul> +<li><a href="/papers/euro-bearer-online-2021.pdf">PDF (English)</a></li> +</ul> + +{% endblock body_content %} diff --git a/papers/euro-bearer-online-2021.pdf b/papers/euro-bearer-online-2021.pdf Binary files differnew file mode 100644 index 00000000..1682c7ac --- /dev/null +++ b/papers/euro-bearer-online-2021.pdf @@ -35,6 +35,11 @@ staticfiles: - robots.txt meetingnotes: newsposts: + - page: 2021-03.html + date: 2021-03-29 + title: Why a Digital Euro should be Online-first and Bearer-based + abstract: + content: - page: 2021-01.html date: 2021-02-23 title: How to issue a Central Bank Digital Currency @@ -164,6 +169,15 @@ videoslist: paperslist: - year: 2021 authors: + - Christian Grothoff + - Florian Dold + kind: Article + name: "Why a Digital Euro should be Online-first and Bearer-based" + url_html: + comment: + url_pdf: "papers/euro-bearer-online-2021.pdf" + - year: 2021 + authors: - David Chaum - Christian Grothoff - Thomas Moser |
