Creation of decentralized identities

No user’s personal data can be stored in the public Blockchain, none, not even encrypted.
The Enrollment process in Blockchain must generate a universal identifier for the user (DID), this identifier must be recorded in the blockchain, so that it is invariable over time and no one can manipulate it.
From the user identifier there can be no inference of user data.
The user password matching process must be performed from a network node, but the password cannot be stored in the network, not even its hash.
