Corda reuses the standard PKIX infrastructure for connecting public keys to identities and thus names are actually X.500 names. When a single string is sufficient the common name field can be used alone, similar to the web PKI. In more complex deployments the additional structure X.500 provides may be useful to differentiate between entities with the same name. For example there are at least five different companies called American Bank and in the past there may have been more than 40 independent banks with that name.
