Go Obfuscated ID

• ID is a value object that use for identify a domain object. The domain entity is only aware of itself, and can never reach across its own object boundaries to find out if an ID it has generated is actually unique. Once a new entity gets persisted as a record in the database it will get an ID. That is, the entity has no identity until it has been persisted.
