Is there a way to modify/re-assign the asset after transfer ?

Question

Im working on a asset management use case where an admin issues asset and assigns it to the user. After doing this, although the current owner of the asset is the user, admin should have permissions to change the custom fields and/or transfer the asset back to his name (assuming admin and user are 2 different nodes on the blockchain).. can this be achieved in multichain ?

Answer 1

If an asset is issued as 'open', then it's possible to perform follow-on issuances of the asset that include updated metadata and zero units.

If you want to the asset to be spendable by both the user and the admin, you should transfer it to a 1-of-2 multisignature made from the user's and admin's address. Then either party can spend it whenever they want. But note that this will not restrict it to only being sent back to the admin.
