I was reading the Sign whitepaper and the bridge section answered something i didn't expect. how does a government run private CBDC and public stablecoin at the same time without them becoming two completely separate systems.
The answer is atomic swaps — convert private CBDC to transparent stablecoin and back, fully or not at all, no funds lost in transit. and the central bank controls the exchange rate, sets conversion limits at individual and aggregate level, applies AML checks on every bridge transaction, and can suspend the bridge entirely if needed.
The whitepaper has a decision matrix — social benefits on public chain for transparency, banking operations on CBDC for privacy, financial payments on both.
From what i understand, $SIGN builds privacy and transparency as separate environments with a sovereign-controlled connection between them, not a tradeoff between them.
Privacy of your payments or transparency of public funds — which matters more to you?
