“A transition to a DLT-based system requires cautious planning and execution and should contain working a DLT-based system in parallel to the prevailing system for some time, maybe indefinitely.”
Technical dangers associated to the reliability and safety of the software program bridge between platforms have been additionally famous, and the usage of the CBDC on networks outdoors of the 2 used within the proof-of-concept was additionally flagged as matters for additional consideration.
SARB says additional work can be undertaken to check the findings from this part of the undertaking and the authorized standing of the wCBDC, which can be used to tell coverage and regulatory responses to DLT and CBDCs within the monetary markets.
It additionally hinted that one other part of Undertaking Khokha could also be began to “construct on the work of PK2, performing reside transactions in a sandbox surroundings in a special use case.”
