EU, blockchain and GDPR: a coexistence that can exist

It has been just over four months since the European Union enacted the General Data Protection Regulation (GDPR) to protect the data of those living in the EU. As pointed out by Darryn Pollock on Forbes, apparently it conflicts with the blockchain.
The GDPR effectively banned the use of the blockchain technology in Europe because of its immutable nature. However, the ideological basis is common: to protect data. Both are seeking greater data security as controllers, processors and data sub-processors.
Sharing the same objective is favoring a level of flexible interpretation, which is helping the blockchain remain relevant in Europe, while still respecting the GDPR.
