With iden3 solution, users can create identities from any connected device with iden3 webapp and manage them.
Because identities are created off-chain, it is not necessary for the users to hold any Ether to create their identities.
They also don’t need to create a transaction to do claims if they use a relayer.
So there is no cost for end users to create and manage all this important information on the public blockchain.
A service provided by iden3 and future alternative providers updates the public blockchain and will pay the cost for updating the information in the public blockchain.
