Abstract

An anonymous token-based central bank digital currency (CBDC) would pose certain security risks to users. These risks arise from how balances are aggregated, from their transactional use and from the competition between suppliers of aggregation solutions. The central bank could mitigate these risks in the design of the CBDC by limiting balances or transfers, modifying liability rules or imposing security protocols on storage providers.
