Features of Central Bank of the Bahamas Sand Dollar and Eastern Caribbean Central Bank DCash (Updated)

I’ve tabulated the key features of the two active central bank digital currency (#CBDC) projects in the Caribbean area. The Central Bank of the Bahamas (CBOB) went live with its Sand Dollar on October 21, 2020 after a ten month pilot, and the Eastern Caribbean Central Bank (ECCB) started a twelve month pilot of its DCash on March 31, 2021 on four of the eight island countries under its currency union. This is all based on publicly-available information – hence some of the question marks. If there are errors of omission or commission, please let me know in the comments! Also, see below for an updated version of the PDF version of the table that includes the Central Bank of Uruguay 2017-2018 e-Peso pilot.

Offline?Users can make a pre-set dollar value of payments when communications access to the Sand Dollar Network is disrupted. Wallets would update against the network once communications were re-established.The party initiating the transfer (sender) must have an internet connection. If the receiver is offline the payment will still be processed, and they will see the change in their balance as soon as they are back online.
Anonymity/Privacy?Transaction transparency to enable central bank monitor suspicious transactions and stop accounts. Pseudonyms ensure user anonymity. Central bank maintains ledger and server is encryptedCentral bank can see anonymized transaction data and outstanding stock of DCash in each digital wallet. Registered financial institutions can fully observe the identity of payers and payees and the purpose of transactions
