Since there is not used mining of tokens, we get all the advantages of the blockchain and not get minuses. We get an unchangeable database of all transactions and all system participants without wasting significant computing capabilities on maintaining this database.
But there is still a problem with decentralization. There should be official servers storing information and informally solving the same problem. Thus, the relevance of the database will be confirmed by several parties.
In this direction there are several technical solutions. I think that this is a trifle. This or that way it will be realized. This is not the basis of the project, in order to give it such increased attention.
