IEEE/ICACT20230237 Question.2 Questioner: s.ahmed1@massey.ac.nz 2023-02-21 오후 12:49:30	IEEE/ICACT20230237 Answer.2 Answer by Auhor sherazmohsin257@gmail.com 2023-02-21 오후 12:49:30
Dear author, Thank you very much for your nice presentation. where the couch DB/level DB used in the system flow diagram>	It is evident that LevelDB and CouchDB (optional) play a role in hyperledger fabric (HLF). While LevelDB is integrated into HLF as a state database, other databases like MongoDB or Redis can replace CouchDB. Normally, HLF uses LevelDB to store the blockchain and CouchDB to store the world state, and this functionality cannot be modified. Therefore, it is not explicitly mentioned in the system flow diagram because it is understood that LevelDB stores the blockchain and CouchDB manage the world state. I have also emphasized this in the manuscript. For more details please follow this link: https://hyperledger-fabric.readthedocs.io/en/release-2.5/couchdb_as_state_database.html#state-database-options Thank you.
