why do we need fabtoken


qs meng <qsmeng@...>
 

Hi experts,
     In the paper "Hyperledger Fabric: A Distributed Operating System for Permissioned Blockchains",  fabtoken is succinctly described. I want to know how much difference there will be between the one in the paper and the one to be implemented.
    In the paper after an utxo is spent, it is said that delstate is called to delete the utxo and it's status is labeld with spent.  I think that means the utxo's status is labeled with spent, not deleted.   I want to know why not delete the utxo entry after the utxo is spent?
   Thank you.
   Best regards,
qs meng
