Unlike Bitcoin and Ethereum, Corda is designed for semi-private networks in which admission requires obtaining an identity signed by a root authority. This assumption is pervasive – the flow API provides messaging in terms of identities, with routing and delivery to underlying nodes being handled automatically. There is no global broadcast at any point. This ‘identity’ does not have to be a legal or true identity. In the same way that an email address is a globally unique pseudonym that is ultimately rooted by the top of the DNS hierarchy, so too can a Corda network work with arbitrary self-selected usernames. The permissioning service can implement any policy it likes as long as the identities it signs are globally unique. Thus an entirely anonymous Corda network is possible if a suitable IP obfuscation system like Tor 6 is also used
