The Token Guy (Roger?),

We are working with tokens sdk as of late and wondering if there are existing patterns controlling who can issue tokens on a business network or is it best to control that on the token spend?

We intend to use the tokens as a means to settle obligations via Corda Settler and were going to add in a "isValidToken(issuer,tokenType)" flow onto our BNO node that would be called during settlement.

Thanks in advance for any ideas or pointing me in the right direction.

Thanks Manos, could you elaborate please.  

I am after an existing pattern if it exists to have a concept of valid issuers on the business network.  

My approach was going to be to check the issuers/token types on the token spend against the BNO which would control who

could issue what.  Just looking for validation to my approach or alternative patterns already proven out.

Thanks,

An issuer whitelist maintained by a business network operator is a sensible approach. You can even distribute the list as a state and require that it is included as a reference state in transactions. Cheers
