As an example; If I have an account on a block chain I still will know what it is and anyone that have been interacting with that account could still identify the account. And GDPR says explicitly that it shouldn’t be possible at all to identify an individual given considering any amount of time and any resources. So I still think an “account” pseudo key in a block chain is still under GDPR. But we’ll probably see those cases in court under various conditions.
