 The smart contract supports UTXO ownership based on individual client identities from organizations that are members of the channel. In our scenario, the minter of the tokens will be a member of Org1, while the recipient will belong to Org2. To highlight the connection between the `GetClientIdentity().GetID()` API and the information within a user's certificate, we will register two new identities using the Org1 and Org2 Certificate Authorities (CA's), and then use the CA's to generate each identity's certificate and private key.
