IPEN Webinar on central bank digital currency

IPEN webinar 2022

IPEN events bring together privacy experts and engineers from public authorities, industry, academia and civil society to discuss relevant challenges and developments for the technological implementation of data protection and privacy.

The EDPS organises on 1st December 2022 an Internet Privacy Engineering Network (IPEN) Webinar entitled:

IPEN webinar on central bank digital currency

Countries around the world are examining whether they should offer central bank money to the public not only as banknotes and coins but also in digital form. While almost 90% of central banks around the world have already launched a state-owned digital currency with different design choices the European Central Bank has decided to start an exploratory phase by 2024. Data protection and security are among the most compelling aspects that impact the core design choices to be taken.

The workshop aims at understanding the challenges and identifying the state of the art of the available design options in the field of transaction validation, auditability and monitoring for compliant and privacy-enhancing solutions.

Connection details will be shared on this page on the same day of the webinar.

Panel 1: “Transaction validation and privacy implications”

 

CBDC in the world opened a huge discussion about the role of the different stakeholders intervening in the validation of transactions of a digital currency when a payment is operated. According to different design choices, different validation mechanisms can be used. How a transaction can be validated and by which actor if a distributed architecture is chosen instead of a centralized one? What is the difference between a bearer-based and an account-based solution is implemented? Moreover, in case the amount of digital currency in circulation is limited via a threshold or a tier approach, how those requirements can be technically enforced while respecting privacy of the different parties involved in the transaction? And what about in case of offline systems that involves secure hardware solutions? How to avoid the possibility to “create money” and/or fake transactions?  In particular, the panel will analyze in depth the privacy implications and the maturity of the privacy enhancing technologies that can support these processing operations.

Panel 2:  “Enhancing privacy in auditability and monitoring” 

 

As any other means of payment, CBDC need to be audited and monitored to a certain extent defined by the law (especially for compliance to AML/CTF purposes). Technologies such as zero knowledge proof, z-cash and homomorphic encryption are getting mature in supporting similar use cases. On the other side, open issues remains on how to guarantee that those solutions are not tampered or have backdoors. While providing general understanding of the more common solutions in CBDC implementation around the world, the panel will focus on the state of the art, the pros and the cons of such solutions.
