The trouble is, in the dispersed network, incorporating new details isn’t really a challenge but modifying it – is.
Short article 17: This article refers to the “right to be forgotten”. It is really not possible to delete facts from a blockchain and therefore this text straight away conflicts using the data safety regulation.

Even inside a authorization chain, the data remains immutable and can’t be deleted or edited. A probable alternative to this is able to be to retail outlet the information on a secure server with browse and produce obtain. We then keep a reference to that data on our blockchain by using a url using a hash function. We will retailer this hash over the blockchain. Hash functions are preferred for verifying the integrity in the documents on our protected server. Also, hash capabilities can’t be reverse engineered to reveal knowledge. If we delete the info to the server, the hash purpose becomes ineffective which is not turns into own details.
