No overload for the public blockchain

Any user can create as many identities as he wants. This is possible because these identities are created and maintained off-chain and don’t need to be registered as an individual transaction in the blockchain. 

The same way, identities can generate as many claims as needed, enabling the concept of  ‘freedom of speech’. To support that and not having to pay gas for all this potential cost, all of these changes are registered into Merkle trees and only the root of the data structure is written in the public blockchain.
