This interconnected network design of a CBDC is very similar to the concept of a decentralized blockchain, which is why CBDCs are often compared to cryptocurrencies. In the CBDC system, the currency is centralized, linked to the legal price, equivalent to the national currency, tracked by the government, and does not show any internal operations. Cryptocurrency systems, on the other hand, are decentralized, can be very volatile, but are globally accessible, preserving privacy while making transactions transparent.
