There are many different flavors of blockchain technology. Public and permissioned blockchains, zero knowledge proofs, different consensus algorithms. One type of blockchain does not fit all purposes. Sometimes, the use of blockchain-technology is an unnecessary overhead and putting hashes of your data on a blockchain might be sufficient to increase transparency.

Majored in computer science and law, Jörn Erbguth can see the whole picture. He is the missing link between lawyers and developers. As a certified Scrum product owner and data protection officer (GDPR, udis certified), he prefers to work with agile teams applying data protection by design.
