Different countries have different regulation rules (eg. AML). What financial regulation rules do Diem comply and implement now (I find there are codes that comply with KYC and travel rule)? If Diem is used worldwide and processed a number of cross-border transactions in the future, will it implement every rule of every country in the future? Or only implement a common set of these rules?
Moreover, I found in documentation and community that Diem will let wallet providers implement and support their own compliance mechanisms, which is the same as the way in some CBDC reports. Will there be some standards to guide wallet providers to implement this?
Additionally, the KYC requires national ID of user. How to check the correctness of that? Will wallet provider connect to the national identity system of every country to check the information and provide wallet services? How to prove security of the information when process cross-border transaction (travel rule)?
