Climate, blockchain and CBDCs: an interview with HyperLedger's Karen Ottoni

However, the longstanding discussion “do you need a blockchain for that?” crops up. Ottoni cites the aforementioned tungsten mining operation in Rwanda as a successful implementation of blockchain technology that is more effective than a database.

Ottoni explains that these actors–good or bad–would “benefit from the visibility of shared data and shared transactions that wasn't as visible before.”

As for CBDCs, which most banks are now considering, Ottoni explains that CBDCs are the “evolution of digitizing assets.” Ottoni expands:

As an example, CBDCs make sense in the wake of a natural disaster: “following a hurricane, CBDCs allow the quick distribution of funds.”
