How does the issuance work?

[UkolovaOlga]

It is organised into a branching tree that always start at genesis, so Vec may be an outdated representation. Basically, you create “inflation rights” at genesis, allocate each of them to some UTXO and specify how much of the inflation this branch may produce. Later, when this UTXO is spent, the issuer creates “inflation” type of state transition, where he specifies to where the newly issued asset is allocated + provides (if necessary) new inflation rights, one or several, such that their sum is equal to the current allowed inflation in the branch minus already issued assets.

Open question: what would be the best representation of that in both rust data structures and SQL tables?
