If you are running BYFN (Build Your First Network) with the CouchDB option, the World State of each peer node is stored a CouchDB server running as Docker container.

The CouchDB server supports an admin web portal that allows you manage the CouchDB server, its databases and documents in each database.

1. Run a Web browser and enter the following URL to use the Web portal CouchDB container linked to peer0.org1:

http://40.121.62.144:5984/_utils/

You see a list of databases on this CouchDB container:

_replicator	2.3 KB	1	
_users	2.3 KB	1	
mychannel_	13.8 KB	2	
mychannel__lifecycle	50.1 KB	0	
mychannel_lscc	0.7 KB	1	
mychannel_mycc  2.7 KB	2

Click on "mychannel_mycc", you see 2 documents reprsenting 2 assets managed by "mycc" chaincode on "mychaneel" channel.
