The Oracle is a special account with extended permissions. Technically, permissions are implemented at the level of access to operations - there are a number of operations that only oracles can perform. The specific list of operations depends on the type of oracle. For example, only a "rights holder oracle" may submit an operation to bind a content identifier to a rights holder.
Each oracle is represented by a separate business entity that can play such a role (for example a law firm), the valid URL of the website of such entity is mandatory and stores in the 'home domain' field of its account.
Adding and removing oracles¶
