Abstract:
Central Bank Digital Currency (CBDC) is a digitized
domestic currency where the central bank issues new
digital money equivalent to its domestic currency. CBDC
could be issued using distributed ledger technology
(DLT) where transactions would operate and settle on a
peer-to-peer basis. There are two types of CBDC, retail
and wholesale. Retail CBDC is issued for general use
which is peer-to-peer payments and payments from
consumers to merchants. Wholesale CBDC is issued for
specific use by commercial banks and clearing houses
aiming at more efficient interbank payments. Many
central banks have already engaged in or about to begin
the CBDC framework. Quite a few central banks start
their CBDC projects building proofs of concept (PoCs)
using DLT to replicate wholesale payment systems such
as the Monetary Authorities of Singapore (Project Ubin),
Bank of Canada (Project Jasper), and Bank of Thailand
(Project Inthanon), and now looking for expanding their
uses to other use cases such as cross- border remittance
and delivery versus Payment (DvP). With an
announcement of Libra global stable coin and global
pandemic which encourages digital payments, many
central banks accelerate their study in retail CBDC with
some has already started testing for example in China. We
are not surveying prior academic work but rather
demonstrate results presented by each Central Banks in
this area. Moreover, this paper also compares analyses of
both technical and business aspects among various
CBDC, identifies challenges, and discuss future works in
this rapidly evolving field.
