only 6% of advanced economies (AE) central banks and 40% of emerging economies (EM) central banks are considering distributed ledger technology (DLT) as an implementation layer for retail CBDCs
here, consider DLT = blockchain
91% of central banks are working on CBDCs, but not on a public blockchain
85 out of 93 central banks (β94% of global economic output) are engaged in some form of CBDC work
however, don't expect CBDCs to be implemented on permissionless blockchains like Ethereum
