[Mandalorian] How do “chaincodes” work and what do they do? Who makes the chaincode for each bounty?

Chaincodes are most likely a form of identification. Similar to a block chain on crypto currency they identify the people involved to some degree so bounties can be tracked and payments rendered appropriately.  Also may be some form of unique identifier similar to a social security number assigned to people through a communication network. Allows a bounty hunter to specifically target the exact person they're after due to likely DNA tracking tied to the chaincode number. How it can be used to track someone from orbit and fit in a tiny device is beyond me however.
