I just read about Joe Biden's executive order (which may be a statement somewhat exaggerated) on Bitcoin[1] which mentions USA CBDC, and I've seen talks about CBDC from other nations, but I'm not sure if they realize how difficult it would be to get this production ready.

I'm wondering if the most realistic solution would end up being implementing it using Bitcoin smart contracts, which most prominent platforms at this point is to my knowledge RGB and then Taro*. Any thoughts on this?

* Taro might catch up fast since it is backed by Lightning Labs
