In many country of EU there were a period of patience to let firms fully covers their GDPR implementation.
However we have GDPR in effect last two years but authorities still had a so called "soft" penalty or no penalty just warn practice which is nearly over.
In mid and longer term the penalty fees will be harmonized. Today every country has its own penalty fees and penalty practice.
There is no more exceptions anymore such as it is technically impossible to delete data, etc.
So will the blockchain illegal among with sks in EU if stored data has PI records?
