Simon Schwerin from BigchainDB talkst about privacy and blockchain:
There are many blockchain applications in the field of identity, IP, finance and energy that are working with personal data. As of May, 28 2018 the new EU GDPR will be implemented, with the aim to strengthen the human rights of individuals, by increasing protection and a feel of ownership of their personal data. It is also supposed to be designed to be technologically neutral and adaptable to processing personal data in different contexts, structures and manners. With regards to blockchain this leaves many questions open, to name a few:
Who will be the data controller in decentralized multi-node systems? – Is there an Accountability Gap? Difference of Private vs. Public set-ups?
Privacy by Design/Default and blockchain core features – Implementation or Clash of Principles? What about the right to be forgotten?
How could a blockchain privacy impact assessment (bPIA) look like to increase the chance of compliance with GDPR next year?
