Wouldn't it easy for a blockchain to just reference external data which then get deleted to comply with GDPR? I know, breaks some ideas about storing data in the chain, but if that's the compromise that works. In the end it will all be about the specific implementation of each blockchain, the idea of blockchains in general will never be endangered like u/mamon suggested.
