If we view Plasma in the context of CBDC (Layer 2 network), its position is actually quite subtle and very real โ it is not the 'issuance layer', but rather the 'circulation layer'.
What is the biggest fear of national digital currencies?
It is not insufficient throughput, but rather cost, controllability, and settlement auditing. The central bank cannot write every coffee payment into the main ledger, but it must be able to reconcile the accounts and assign responsibility when issues arise.
This just happens to fit into Plasma's comfort zone.
In theory,
#CBDC the mainnet can only be responsible for issuance, recycling, and final settlement, while Plasma, as a Layer 2, carries out daily high-frequency small payments: public transport, retail, cross-border
#B2B settlements. Block headers regularly anchor to the main ledger, while off-chain operations occur normally, returning to the mainnet for arbitration in case of issues โ sovereignty is not delegated, but the load is delegated.
More importantly, the control structure.
Plasma inherently supports permissioned operators: who can create blocks, who can view data, and who can participate in validation can all be designed institutionally. This is psychologically much safer for central banks than a completely open Rollup.
Of course, risks are also on the table:
Data availability, historical record withholding, exit windows; these are already complex enough in civilian scenarios, and cannot rely on 'user self-rescue' in national-level systems.
So if
#Plasma really wants to enter the CBDC system, its role will not be that of an idealistic decentralized network, but more like an auditable, pausable, and accountable settlement buffer layer.
In summary:
Plasma is not suitable as the nationโs money, but it is very suitable for the segment of the journey of the nation's money.
