This tutorial provides guides on CA* server creation, administrator/user registration, and MSP registration procedure for each user among the network configuration steps for using MDL Manager*.

* MDL Manager
-     A high-speed blockchain application platform that operates based on Hyperledger Fabric, allowing users to flexibly deploy and manage nodes, channels, and chaincodes by building a network environment through an intuitive UI.

* CA (Certificate Authority)
-     A certification authority that manages node roles and privileges in the network through Hyperledger Fabric's management system (MSP, Membership Service Provider) for user rights and authentication

※ Through this process, you can register a certificate that confirms the user's signature and authority.

※ This guides you through a series of procedures for distributing the chaincode after configuring the network with 1CA (1ORG), 2Orderer, and 2Peer, and checking the result by executing Invoke and query on the distributed chaincode.
