Enterprise blockchains and identity management


Enterprise blockhcain solutions has usually totally different directions regarding identity management and user authentication. They usually integrate some kind of cloud or more decentralized identity management system, efficiently authenticating and personalizing every transaction and access to the system. Examples are Azure Blockchain as a Service with the help of Active Directory Services or Hyperledger Fabric Composer with the help of Membership Service. It is totally different from the open public world however, where you generate a public private key pair and practically the private key represents the identity. However even in enterprise scenarios, the two approaches should be combined. One part of the service might be authenticated with the help of classical centralized identity services, however part of the application could follow classical antonym authentication methods with the help of private - public keys. The authentication situation might be an analogy to the a classical portal system, where you can reach some of the content publicly on the internet as other content and services are protected with classical identity management systems.
